How This VA Disability Rating Calculator Works
A VA disability rating calculator estimates the combined disability evaluation that results when more than one service-connected condition has an assigned percentage. Use this calculator to enter VA-style ratings from 0% to 100%, mark paired left-and-right conditions when the bilateral factor may apply, and see the raw combined value before VA final rounding.
The calculator is built around the whole person method used in the combined ratings table. Instead of adding percentages as if they were separate piles, VA starts with a whole person, applies the largest disability first, then applies each lower disability to the efficient portion that remains. That is why two or more ratings often produce a combined value lower than a simple added total.
For example, a 50% rating means 50% of the whole person is disabled and 50% remains efficient. If a 30% rating is then applied, the 30% affects the remaining 50% efficient portion, which adds 15 percentage points. The result is 65%, and VA final rounding converts 65% to a 70% combined rating.
This tool is not a claim decision, medical opinion, legal opinion, or payment estimate. It is a structured calculator for understanding the arithmetic. If the result affects a filing decision, appeal strategy, or household planning, compare it with VA records and qualified help. For quick percentage arithmetic outside the VA method, the Percentage Calculator can help with ordinary percentage questions.
Core whole person formula
The formula mirrors the table logic. The term 100 - current combined value is the remaining efficiency. The next rating is applied only to that remaining efficiency. The calculator rounds each table-style combination to the nearest whole number before moving to the next rating, then performs final rounding to the nearest 10% at the end.
Final VA rounding formula
A raw combined value of 64% rounds to 60%. A raw combined value of 65% rounds to 70%. A raw combined value of 94% rounds to 90%, while 95% rounds to 100%. This final rounding step happens after all ordinary and bilateral combinations have been handled.
What the calculator displays
The result panel shows the VA-rounded rating, the raw combined value, remaining whole-person efficiency, the largest individual rating, a simple added total for comparison, and a bilateral factor note. The combination order panel shows how each rating changes the combined value step by step.
Important scope note
This page estimates combined disability percentage and a monthly compensation amount from selected 2026 table values. It does not decide service connection, effective dates, special monthly compensation entitlement, unemployability, or dependency eligibility.
How to Use the VA Disability Rating Calculator
Use the calculator when you have a list of assigned ratings or when you want to model a possible combination. The cleanest inputs come from a VA decision letter or the disability rating section of a VA.gov account. If you are testing a possible future decision, label the entries clearly so you do not confuse a scenario with an official result.
- Enter the first assigned VA disability rating.
- Choose whether the condition is general, left-sided, right-sided, or paired muscle related.
- Add each additional rating from the VA decision or your planned scenario.
- Review the bilateral factor note if paired left-and-right ratings are present.
- Read the raw combined value, the final VA-rounded combined rating, and the estimated monthly payment amount.
After each entry, the tool recalculates the estimate. You can leave a 0% condition in the list for recordkeeping, but it will not change the combined rating. If a condition affects a paired body area, choose the matching left or right option so the bilateral factor check has the information it needs.
Input checklist
| Input | Accepted values | Why it matters |
|---|---|---|
| Rating | 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% | VA ratings usually move in 10% steps for this combined-rating calculation. |
| Label | Short condition name | Keeps the combination order and current-ratings list readable. |
| Affected area | General, left upper, right upper, left lower, right lower, left paired muscle, right paired muscle | Helps the calculator identify possible bilateral factor entries. |
| Number of entries | 1 to 12 | Keeps the calculator practical and the step list readable. |
| Pending scenario | Optional | Useful for modeling, but not an official VA outcome. |
A simple entry example
Suppose a veteran has ratings of 50%, 30%, and 10%. Enter the 50% condition first or last; the calculator will sort ratings from highest to lowest for the combination process. The raw combined value becomes 69%, and final VA rounding makes the combined rating 70%.
When to mark left or right
Mark left or right only when the rating affects a paired extremity or paired skeletal muscle. For a condition that is not tied to a paired left/right body part, choose General. If you are unsure how VA coded a condition, check the decision narrative or ask an accredited representative.
Recordkeeping tip
Keep calculator scenarios separate from official assigned ratings. A clear label like Proposed shoulder increase or Current knee rating can prevent confusion later.
VA Math and the Whole Person Method
The whole person method is the central idea behind VA combined ratings. It begins at 100% efficiency. A 60% disability leaves 40% efficiency. If a 30% disability is added next, it affects that remaining 40%, not the original 100%. Thirty percent of 40 is 12, so the combined value becomes 72%.
This structure prevents a person from being more than 100% disabled under the standard combined-rating scale. It also means that each additional rating has a smaller effect as the combined value gets higher. A 10% rating added to 20% moves the value more than a 10% rating added to 90%, because the remaining efficiency is much larger at 20%.
The formula can be written in several equivalent ways. The calculator uses the remaining-efficiency version because it is easiest to read and explain. If you want to compare how a non-VA value changes from one number to another, the Percentage Change Calculator is better for that separate task.
Whole person example with 60% and 30%
| Step | Action | Calculation | Combined value |
|---|---|---|---|
| 1 | Start with the largest rating | 60% disability leaves 40% efficient | 60% |
| 2 | Apply next rating to remaining efficiency | 30% x 40 = 12 | 72% |
| 3 | Round only after all ratings are combined | 72 is nearest to 70 | 70% final |
| 4 | Compare with simple addition | 60 + 30 = 90 | Not the VA combined value |
Why the order matters before combining
VA arranges disabilities in order of severity, beginning with the greatest disability. When table rounding is used after each pair, the standard process is to combine from highest to lowest. The calculator sorts the entries for you so the current-ratings list can be entered in any order.
Why small ratings matter less near the top
If a veteran is already at a raw combined value of 90%, a new 10% rating applies to the remaining 10% efficiency. That adds only 1 point, making 91%, which still rounds to 90%. A larger new rating or several added ratings may be needed to cross the next final rounding boundary.
Practical reading
A rating can be medically important and still have a small effect on the final combined percentage. The calculator explains the arithmetic, not the seriousness of any condition.
Combined Ratings Table Logic in Plain English
The combined ratings table can look intimidating because it is a grid, but the concept is consistent. The left side is the current combined value or the larger rating. The top row is the next lower rating. The point where the row and column meet gives the new combined value. The calculator performs that same table-style operation automatically.
For two ratings, the process is short. For three or more ratings, VA combines the first two, keeps that combined value unrounded to the nearest 10, then combines that whole-number table value with the next rating. The nearest-10 final rounding is saved until the last step.
Common pair combinations
| Rating A | Rating B | Raw combined value | Final VA rounded rating |
|---|---|---|---|
| 10% | 10% | 19% | 20% |
| 20% | 20% | 36% | 40% |
| 30% | 20% | 44% | 40% |
| 40% | 20% | 52% | 50% |
| 50% | 30% | 65% | 70% |
| 60% | 40% | 76% | 80% |
| 80% | 10% | 82% | 80% |
Multi-rating example
This example explains why the final answer is not 90%. The first two ratings produce 65%. The next 10% is applied to the remaining 35% efficiency, which adds about 3.5 points and becomes 69% after table-style whole-number rounding. The final rating is 70%.
Decimal thinking versus table thinking
The combined ratings table uses whole-number combined values. Formula examples sometimes produce decimals before rounding, especially when explaining the concept. The calculator follows table-style whole-number behavior so examples like 50% plus 30% become 65% and 65% plus 10% becomes 69%.
Helpful arithmetic habit
If you are checking the math by hand, keep two numbers in view: the current combined value and the remaining efficiency. That makes the next step easier to audit.
Bilateral Factor Rules and Examples
The bilateral factor is a special adjustment for certain compensable disabilities affecting both sides of paired extremities or paired skeletal muscles. In plain terms, if there are qualifying left-and-right paired ratings, those paired ratings are combined first, then 10% of that paired subtotal is added before the result is combined with the other ratings.
The calculator lets you choose general, left upper, right upper, left lower, right lower, left paired muscle, or right paired muscle. A bilateral factor needs compensable ratings on both sides of a pair. A 0% left-side entry does not trigger the factor because the rule requires a compensable degree on each paired side.
Bilateral calculations can be confusing because the paired subtotal becomes a single rating for the rest of the combination. If you need to convert a decimal explanation into a simplified fraction for a worksheet or note, the Decimal to Fraction Calculator can help outside the VA rating process.
Bilateral factor formula
Bilateral factor examples
| Paired ratings entered | Paired combined value | 10% factor added | Subtotal used before other ratings |
|---|---|---|---|
| Left leg 10%, right leg 10% | 19% | 1.9 | 21% |
| Left arm 20%, right arm 20% | 36% | 3.6 | 40% |
| Left leg 30%, right leg 10% | 37% | 3.7 | 41% |
| Left upper 20%, right upper 10%, left lower 10%, right lower 10% | 42% | 4.2 | 46% |
| Left paired muscle 40%, right paired muscle 20% | 52% | 5.2 | 57% |
The subtotal used before other ratings is rounded to a whole number for table-style combining. For example, two 10% paired leg ratings combine to 19%. The bilateral factor adds 1.9, making 20.9, which is used as 21% before it is combined with any remaining ratings.
Most favorable bilateral handling
Federal rules recognize that including every possible paired entry in the bilateral calculation should not reduce the veteran's combined evaluation. This calculator tests eligible paired subsets and uses the result that creates the highest final rounded rating from the entries supplied.
When to be careful
Bilateral coding can depend on how VA describes the disability, not only on everyday wording. If the official decision uses body systems, diagnostic codes, or combined descriptions that are unclear, use the calculator as a teaching aid and verify with a qualified source.
Final Rounding Boundaries
Final rounding is one of the most important parts of VA combined rating math. The raw combined value is converted to the nearest number divisible by 10. Values ending in 1 through 4 round down, and values ending in 5 through 9 round up. This final conversion happens only after the ratings, including any bilateral factor, have been combined.
The boundary can be surprising near 95%. A raw combined value of 94% remains a 90% final rating, but 95% rounds to 100%. The same pattern applies throughout the scale: 74% rounds to 70%, while 75% rounds to 80%.
VA final rounding table
| Raw combined value | Final rounded rating | Boundary note |
|---|---|---|
| 0% to 4% | 0% | No compensable final rating unless the raw value reaches 5%. |
| 5% to 14% | 10% | Values ending in 5 or more round upward. |
| 15% to 24% | 20% | The nearest 10% is used. |
| 25% to 34% | 30% | The midpoint rounds upward. |
| 35% to 44% | 40% | A raw value of 44% is still 40%. |
| 45% to 54% | 50% | A raw value of 45% becomes 50%. |
| 55% to 64% | 60% | The same rule continues. |
| 65% to 74% | 70% | A 65% value becomes 70%. |
| 75% to 84% | 80% | This is a common boundary area. |
| 85% to 94% | 90% | 94% remains 90%. |
| 95% to 100% | 100% | 95% reaches the 100% final rating. |
Boundary example
This is why a small added rating may or may not move the final result. If the raw value moves from 82% to 84%, the final rating stays 80%. If it moves from 84% to 85%, the final rating becomes 90%. For ordinary fraction practice unrelated to VA rules, the Fractions Calculator can help check step-by-step arithmetic.
Why the final step matters
The final rounded rating is the value most people recognize because it appears in 10% increments. The raw combined value is still useful because it shows how close the estimate is to the next boundary.
Calculator display tip
Read both the raw value and the rounded value. The raw value explains movement; the rounded value is the combined percentage category.
Worked Examples for Common Rating Sets
Examples make VA math easier because the same pattern repeats no matter how many ratings are entered. The key is to combine from highest to lowest, hold final nearest-10 rounding until the end, and apply any qualifying bilateral factor before the remaining ratings are combined.
Example 1: two ratings
A veteran has 40% and 20%. The combined value is 40 + 20 x 60 / 100 = 52%. Final rounding converts 52% to 50%. Simple addition would say 60%, but the whole person method says 50%.
Example 2: three ratings
A veteran has 60%, 30%, and 10%. First, 60 and 30 combine to 72. Then 72 and 10 combine to 75. The final VA-rounded combined rating is 80%. The last 10% mattered because the raw value crossed a rounding boundary.
Example 3: bilateral pair plus another rating
A veteran has right leg 10%, left leg 10%, and a general 60% rating. The two leg ratings combine to 19. The bilateral factor adds 1.9, making 20.9, used as 21. Then 60 and 21 combine to 68, and the final rating rounds to 70%.
Example 4: high raw value near 100%
A veteran has ratings that combine to 94%. The final rating is 90%, not 100%. Another rating may push the raw value to 95% or higher, but it depends on the remaining efficiency, not on simple addition.
| Scenario | Ratings | Raw combined value | Final VA-rounded rating |
|---|---|---|---|
| Two moderate ratings | 40%, 20% | 52% | 50% |
| Three ratings | 60%, 30%, 10% | 75% | 80% |
| Two small ratings | 10%, 10% | 19% | 20% |
| Bilateral pair plus large rating | 60%, right leg 10%, left leg 10% | 68% | 70% |
| Near top boundary | Inputs combine to 94% | 94% | 90% |
| Top boundary crossed | Inputs combine to 95% | 95% | 100% |
If you are comparing a rating decision date with another deadline, keep the date math separate from the rating math. The Days Between Dates Calculator can count calendar-day gaps without changing the disability calculation.
Why Simple Addition Can Mislead
Simple addition is useful for many everyday tasks, but it is not how VA combined ratings work. Adding 50% and 30% to get 80% ignores the fact that the second rating applies to the portion of the whole person that remains efficient after the first rating. The table method accounts for that remaining efficiency.
The gap between simple addition and VA math grows as more ratings are added. Three ratings of 30%, 20%, and 10% add to 60%, but the VA combined value is 50% before final rounding. That does not mean a condition was ignored; it means the ratings were combined under a different arithmetic rule.
Simple sum versus VA combined value
| Ratings | Simple added total | VA raw combined value | Final rounded rating |
|---|---|---|---|
| 30%, 20% | 50% | 44% | 40% |
| 50%, 30% | 80% | 65% | 70% |
| 60%, 30%, 10% | 100% | 75% | 80% |
| 70%, 20%, 10% | 100% | 78% | 80% |
| 80%, 10%, 10% | 100% | 84% | 80% |
| 90%, 10% | 100% | 91% | 90% |
What simple addition is still good for
Simple addition can help count how many assigned ratings you are tracking or show why VA math feels different. It should not be used to predict the final combined rating. The calculator shows the simple sum only as a comparison point.
Ordinary percentage tasks
Outside VA disability math, ordinary percentage tools still have a place. If you are comparing two non-rating numbers, checking a discount, or finding a share of a total, use a normal percentage formula instead of the whole person method.
Avoid this mistake
Do not subtract the simple sum from 100 and treat that as remaining efficiency. Remaining efficiency is recalculated after each whole-person combination.
Effective Dates, Age, and Record Timing
Combined rating math answers one question: what rating results from the percentages entered? It does not answer when the rating begins, whether a dependent is counted, whether a staged rating applies, or whether a decision is final. Those timing details often matter in the real world, but they are separate from the arithmetic on this page.
Effective dates can differ by claim type, evidence, appeal path, and VA decision history. If you are organizing dates for personal records, use exact calendar dates rather than relative wording. The Days From Today Calculator can help when you need to count forward or backward from a known date.
Age and dependent context
Age can matter for dependent children, school attendance questions, and records that use exact birthdays. This calculator does not decide dependency status, but if you need a clean age from a birthdate, the Age Calculator can keep that separate from the rating estimate.
Chronological age checks
Some records need age on a specific date rather than age today. In that situation, the Chronological Age Calculator can calculate exact years, months, and days for a selected date.
Comparing two people or dates
If you are comparing ages between two dependents, caregivers, or household members for a form, the Age Difference Calculator can provide that date-based comparison without mixing it into the VA rating math.
Timing caution
A calculator cannot infer the effective date of a rating. Use official VA notices and qualified guidance when dates affect payment, filing windows, or appeal choices.
Understanding 0%, 100%, and Edge Cases
Some rating entries behave differently from what people expect. A 0% rating can be service connected but noncompensable, so it does not change the combined value. A 100% schedular rating generally drives the combined value to 100% because no efficiency remains for the table formula to reduce further.
A 0% entry can still be worth listing for personal organization. The calculator allows it for that reason. It will appear in the current-ratings list, but it will not count as compensable for the bilateral factor and will not change the result panel.
Edge case table
| Situation | Calculator behavior | Reason |
|---|---|---|
| Only one 0% rating | Final estimate is 0% | No compensable percentage changes the combined value. |
| 0% plus 40% | Final estimate is 40% | The 0% entry has no arithmetic effect. |
| 100% plus any lower rating | Final estimate is 100% | A 100% rating leaves no remaining efficiency. |
| Left 0% and right 10% | No bilateral factor | Both sides must be compensable. |
| Left 10% and right 10% | Bilateral factor may apply | Both sides are compensable paired entries. |
| Raw 94% | Final estimate is 90% | Final rounding has not crossed 95%. |
| Raw 95% | Final estimate is 100% | Final rounding reaches the top boundary. |
When the calculator and VA records differ
Differences usually come from missing ratings, incorrect body-side marking, staged decisions, bilateral coding, a condition not yet service connected, a changed decision, or a special rule outside this calculator. Start by checking that every entered rating matches the official record.
When money planning is separate
Monthly VA compensation depends on more than the combined rating. If you are also planning household income from a job, the Pay Raise Calculator can keep wage changes separate from VA disability rating math.
Work-hour planning
If job hours or extra shifts are part of your budget notes, keep that arithmetic separate too. The Overtime Calculator handles work-hour pay estimates without affecting this disability rating calculation.
Manual Calculation Walkthrough
You can audit a calculator result by hand with a short worksheet. Write the ratings from highest to lowest. If a bilateral factor applies, combine the qualifying paired ratings first, add 10% of that paired subtotal, round that subtotal to a whole number, and treat it as one rating in the main list. Then combine the list from highest to lowest.
Manual worksheet formula set
Worksheet example with 70%, 20%, and 10%
Start with 70%. Remaining efficiency is 30%. Apply 20% to that remaining 30%, which adds 6 points, so the combined value is 76%. Remaining efficiency is now 24%. Apply 10% to 24, which adds 2.4 points, rounded through table behavior to 78%. Final rounding keeps the result at 80%.
Audit table
| Step | Current value | Next rating | Remaining efficiency | New combined value |
|---|---|---|---|---|
| Start | 0% | 70% | 100% | 70% |
| Second | 70% | 20% | 30% | 76% |
| Third | 76% | 10% | 24% | 78% |
| Final | 78% | Round to nearest 10 | Not applicable | 80% |
Manual audit limit
A manual worksheet can verify the arithmetic, but it cannot decide whether a rating should be paired, whether a condition is service connected, or whether a special rule applies.
Official References and Calculator Limits
The public VA explanation of disability ratings describes the whole person theory and shows how multiple ratings are combined rather than added. The federal regulation at 38 CFR 4.25 describes the combined ratings table, and 38 CFR 4.26 describes the bilateral factor. Those official references are the basis for the educational approach used here.
Even with correct arithmetic, a calculator is not a substitute for the official record. VA decisions can include effective dates, staged evaluations, diagnostic code changes, severance questions, reductions, special monthly compensation, individual unemployability, dependents, and appeal issues. Those topics need record-specific review.
What this calculator can and cannot do
| Topic | Calculator can estimate? | Reason |
|---|---|---|
| Combined schedular percentage from entered ratings | Yes | The whole person formula and final rounding are arithmetic. |
| Bilateral factor from marked paired entries | Yes, as an estimate | The calculator can test paired left/right entries you provide. |
| Monthly compensation | Yes, as a table estimate | The tool applies selected 2026 VA table values after the rating is calculated. |
| Service connection | No | That is a claim decision based on evidence and law. |
| Effective date | No | That depends on claim history and VA rules. |
| SMC(k) add-on amount | Yes, as a selected add-on | The tool can add selected SMC(k) award counts, but it cannot decide entitlement. |
| Individual unemployability | No | IU involves employability and additional standards. |
Good verification habits
- Compare every entered rating with the most recent VA decision or VA.gov record.
- Check whether paired body entries are actually compensable left-and-right conditions.
- Review the raw combined value before reading the rounded value.
- Compare the estimated payment with current VA tables and approved dependent records.
- Ask an accredited representative when a result affects a filing or appeal choice.
Why official wording matters
A condition label in everyday language may not match the official VA description. The decision letter, diagnostic code, and body-side wording can affect whether an entry belongs in the bilateral factor section.
Plain language bottom line
Use this calculator to understand the math, then use official records to confirm the facts.
What Happens Before Ratings Reach the Calculator
The calculator begins after ratings already exist, but a real VA disability percentage starts earlier. VA assigns an evaluation to each service-connected condition based on how severe the condition is under the rating schedule. The percentage is a shorthand way to describe loss of health or functional capacity for that condition, not a direct measurement of income, pain, or personal difficulty.
The document you provided emphasizes an important distinction: the combined rating calculator does not decide whether a condition should be service connected or how severe it should be. That decision depends on evidence, examinations, records, and rating rules. Once those individual ratings are assigned, the calculator can help explain how they combine.
Common inputs VA may review before assigning a percentage
| Information source | What it may show | Calculator role |
|---|---|---|
| Medical records | Diagnosis, symptoms, treatment history, and functional limits | Used before the calculator; not entered directly. |
| Doctor reports or test results | Objective findings and severity details | May support a rating, but the calculator only needs the final percentage. |
| VA claim exam | Examiner findings from a compensation and pension exam | Can influence the assigned rating; not a calculator input. |
| Other federal or service records | Service history, prior records, or agency information | May support the claim record, but not the combined math. |
| Rating decision | The official percentage for each service-connected condition | This is the best source for calculator entries. |
Why this distinction matters
A user may see many numbers in a VA record: dates, diagnostic codes, exam measurements, test values, old percentages, and current percentages. Only the current assigned disability percentage belongs in the combined-rating calculation for the period being checked. Entering a diagnostic code or exam measurement as though it were a rating will produce a misleading result.
What the calculator can confirm
The calculator can confirm the arithmetic path from individual percentages to a combined percentage. It cannot confirm whether a rating should have been higher, whether the evidence was weighed correctly, whether an exam was adequate, or whether an effective date was assigned correctly.
Plain workflow
First identify the official rating percentages. Then enter those percentages here. Finally, compare the raw combined value and rounded rating with the official combined evaluation.
Preservice Aggravation and Why It Is Separate
The document also mentions a situation that can confuse calculator users: a condition that existed before service but became worse because of service. In that setting, VA may focus on the level of aggravation. In plain language, aggravation is the portion of worsening attributed to service, not necessarily the entire current severity of the condition.
For calculator purposes, do not try to subtract preservice severity yourself unless the official decision already gives you the rating percentage to use. The combined rating calculator is not designed to decide the aggravation level. It combines the ratings that are assigned after VA applies the relevant rule.
Aggravation example in calculator terms
| Stage | Example percentage | Meaning for this calculator |
|---|---|---|
| Before service | 10% | A baseline severity may be identified in the record. |
| After service worsening | 20% | The condition may now meet a higher severity level. |
| Aggravation level | 10 percentage points | This may affect the rating VA assigns for compensation purposes. |
| Calculator entry | Use the assigned rating from the VA decision | Do not invent a calculator entry from the example alone. |
Why not calculate aggravation inside this tool
Aggravation is a rating-decision issue, not just arithmetic. It may involve medical baseline evidence, service records, and legal standards. A combined-rating tool should not pretend to decide that background question. It should wait for the assigned percentage and then combine that percentage with the rest of the ratings.
Good user habit
If a decision discusses preservice aggravation, label the condition clearly in your notes but enter only the percentage that VA assigned for the period you are checking.
Scope reminder
This calculator estimates combined rating math after individual evaluations are known. It does not assign or revise those individual evaluations.
Combined Ratings Table Lookup Excerpt
The document includes combined-rating tables split into ranges, which is how a large table becomes easier to scan. The calculator does not need to display every row because it calculates the same intersections directly. Still, a short excerpt helps users see the table method: current value down the left side, next rating across the top, and the intersection as the new combined value.
The values below are table-style whole-number combined values before final rounding to the nearest 10%. They are not copied as a layout from the document; they are generated from the same whole-person formula the calculator uses.
Selected lookup values
| Current combined value | +10% | +20% | +30% | +40% | +50% |
|---|---|---|---|---|---|
| 50% | 55% | 60% | 65% | 70% | 75% |
| 60% | 64% | 68% | 72% | 76% | 80% |
| 65% | 69% | 72% | 76% | 79% | 83% |
| 70% | 73% | 76% | 79% | 82% | 85% |
| 80% | 82% | 84% | 86% | 88% | 90% |
| 90% | 91% | 92% | 93% | 94% | 95% |
How to read this excerpt
If the current combined value is 50% and the next rating is 30%, the intersection is 65%. If there are only two ratings, that 65% then rounds to 70%. If more ratings remain, 65% becomes the current combined value for the next lookup instead of being rounded to the nearest 10% immediately.
Why the calculator still shows steps
A full table is useful for manual checking, but step-by-step output is easier for most users. The calculator sorts ratings from high to low, applies any eligible bilateral subtotal, and then shows each combination step so the user does not have to hunt across several table blocks.
Final rounding caution
Table values in this excerpt are raw combined values. The final VA-rounded rating comes after the last rating has been combined.
2026 VA Monthly Compensation Tables Used by the Calculator
The monthly estimate in the result panel uses 2026 VA disability compensation table values effective December 1, 2025. Ratings of 10% and 20% use a flat monthly amount. Ratings of 30% through 100% may increase when qualifying dependents are selected.
The document you provided includes the same payment-table structure: a short 10% to 20% table, standard dependent tables for 30% to 100%, parent-dependent tables, and extra amounts for additional children, schoolchildren, and a spouse who needs Aid and Attendance. The calculator turns those table rows into a live estimate.
10% and 20% base rates
| VA disability rating | Monthly amount |
|---|---|
| 10% | $180.42 |
| 20% | $356.66 |
SMC(k) add-on amounts modeled by the calculator
| SMC(k) awards selected | Added monthly amount |
|---|---|
| 0 | $0.00 |
| 1 | $139.87 |
| 2 | $279.74 |

How the calculator uses these tables
First, the calculator finds the final VA-rounded rating. Next, it selects the row that matches spouse, child, and parent choices. If more than one child is entered, it adds the extra child amounts after the first child is already included in the basic child row. If SMC(k) awards are selected, the SMC(k) amount is added separately.
Why one value was corrected
The provided document listed the 30% veteran-with-child value as $595.47 in one place. The current VA 2026 table lists that amount as $596.47, so the calculator and article use $596.47.
Payment estimate caution
A payment table can estimate the monthly amount from selected factors, but it cannot confirm dependency approval, effective dates, retroactive periods, withholdings, offsets, or special monthly compensation entitlement.
Reading the Result in Real Claim Records
A calculator result becomes more useful when it is matched against the way VA records are actually written. A decision letter may list each condition, the evaluation assigned, the effective date, a diagnostic code, and a short explanation of the evidence considered. The calculator only needs the percentage and, when relevant, the left or right paired body area. The other details still matter, but they answer different questions.
Start by separating the rating list from the narrative. The rating list gives the percentages. The narrative explains why VA granted, denied, continued, increased, or decreased a condition. If you copy every number from the narrative without checking whether it is an assigned percentage, you can accidentally enter exam measurements, dates, diagnostic code numbers, or prior evaluations that are not current ratings.
A common recordkeeping mistake is mixing current ratings with historical ratings. A veteran may have had a 10% evaluation in an older period and a 30% evaluation in a later period. If the goal is to estimate today's combined rating, enter the current assigned rating for each condition. If the goal is to understand a past period, enter the ratings that applied to that past period. Do not blend the periods unless you are intentionally modeling a scenario.
Current rating versus staged rating
A staged rating means a condition had different evaluations during different time periods. For example, a condition might be 10% for one period and 30% starting on a later date. The calculator can estimate each period, but it cannot decide which period applies. To audit staged ratings, run one calculation for the first period and a separate calculation for the later period, using only the ratings assigned during each period.
This matters because a combined rating can change even when only one condition changes. If a veteran moves from 70% raw to 74% raw, the final rating remains 70%. If the same change moves the raw value from 74% to 75%, the final rating becomes 80%. A staged decision can therefore create a different final combined percentage in one period but not another.
Diagnostic code numbers are not rating percentages
Diagnostic codes can look like numbers that belong in a calculator, but they are not percentages. A code may be four digits or may include a hyphenated format. Do not enter diagnostic code numbers as ratings. Enter only the assigned evaluation, such as 10%, 30%, or 70%. If a condition has multiple diagnostic-code references but one assigned evaluation, use the assigned evaluation.
The same caution applies to exam measurements. A medical examination might list degrees of motion, number of painful episodes, frequency of symptoms, or other measurements. Those figures may explain the decision, but they are not automatically disability ratings. The calculator begins after VA has assigned a rating percentage.
Old rating decisions and current records
If you have several decisions, use the most recent official record for the period you are checking. Older decisions can be useful for history, but they may have been replaced by later grants, reductions, increases, corrections, or appeal outcomes. A calculator cannot detect that history unless you enter the correct set of ratings.
When records conflict, slow down and identify the source. A VA.gov summary, a rating decision, a letter, and a representative's worksheet may not all have been updated at the same moment. If the difference matters, use official notices and qualified support rather than guessing from a calculator result.
Practical record review order
First list the current service-connected conditions. Second write the assigned percentage for each condition. Third mark only clearly paired left-and-right compensable entries. Fourth run the calculator. Fifth compare the final estimate with the official combined evaluation and investigate any mismatch.
Troubleshooting a Mismatch
If the calculator result does not match the official combined rating, do not assume the calculator or VA record is wrong immediately. Most mismatches come from input differences. The calculator only knows the entries you provide. One missing rating, one extra historical rating, or one paired body setting can change the result enough to cross a final rounding boundary.
Begin with the simplest check: count the conditions. If the official record lists eight service-connected ratings and the calculator has seven, find the missing entry. If the calculator has nine entries, check whether a historical, proposed, or denied condition was accidentally included. The number of entries will not always prove the result, but it quickly exposes many mistakes.
Check the exact percentage values
A 20% entry accidentally entered as 30% can change the final result. A 0% condition accidentally entered as 10% can also change the raw combined value and may create a false bilateral factor if it is marked as paired. Review each percentage from the official list and match it line by line against the current-ratings panel.
Be especially careful with increases and reductions. If a condition changed from 10% to 20%, enter the rating for the period you are checking. If a decision proposed a reduction but did not yet make it final, do not enter the proposed percentage as the current rating unless you are intentionally modeling that possible scenario.
Check body-side and bilateral settings
The bilateral factor is a frequent source of mismatch because it depends on paired left-and-right compensable disabilities. A condition described as bilateral in ordinary language may not be entered as two separate left-and-right compensable ratings. Another condition may be listed separately for each side. The calculator needs the structure that matches the rating record.
If the official combined rating is higher than the calculator estimate, a missing bilateral factor may be the reason. If the calculator estimate is higher than the official record, you may have marked a condition as paired when it should be general, or you may have included a condition that is not service connected for the period being checked.
Check final rounding boundaries
Sometimes a mismatch is only apparent. A raw combined value of 74% and a raw combined value of 70% both round to 70%. If you compare only final rounded ratings, you may miss that the raw values differ. Conversely, a one-point raw difference near a midpoint can change the final rating. Always inspect the raw combined value when troubleshooting.
Near 95%, the boundary becomes especially important. A calculator estimate of 94% raw produces 90% final, while 95% raw produces 100% final. If an official record is near that boundary, a small input difference can look dramatic in the final rounded result.
When to stop troubleshooting alone
If the rating list, percentages, body-side settings, and period all appear correct but the result still differs from the official record, stop treating the issue as simple arithmetic. There may be a special rule, coding issue, staged period, correction, or document timing problem. That is the point where an accredited representative or other qualified help is more useful than repeated calculator edits.
A good calculator should make your next question clearer. It should not push you into certainty when the records are unclear. Use the mismatch as a signal to review the source documents, not as proof that a decision is wrong. The calculator gives a transparent arithmetic estimate from entered values; the official record controls the actual assigned rating.
Modeling Scenarios Without Confusing Them With Official Ratings
Many people use a VA disability rating calculator for two different tasks. The first task is an audit of assigned ratings that already exist in the official record. The second task is scenario modeling, where a person asks what might happen if one condition increased, one new condition were granted, or a paired left-and-right condition became compensable. Both tasks are reasonable, but they should not be mixed in the same saved note.
For an audit, use only the percentages that are currently assigned for the period being checked. For a scenario, write down that the entry is hypothetical before you run the calculation. A label such as possible increase or modeled new rating is plain enough to prevent confusion later. If you return to the calculator days or weeks later, those labels will remind you that the result was not an official VA outcome.
One-change scenario method
The cleanest scenario method changes one variable at a time. Start with the current assigned ratings and confirm that the calculator reproduces the expected combined value. Then change only one rating, add only one possible new condition, or change only one affected-area setting. Read the raw combined value and final rounded value. If the result changes, you know which entry caused the movement.
Changing several entries at once can still be useful, but it is harder to explain. If a 70% final rating becomes 90% after three edits, you may not know which edit crossed the boundary. A one-change method gives better notes because it connects a result to a specific assumption.
Boundary-aware scenario notes
When the raw combined value is close to a rounding boundary, record the raw value, not only the final rounded percentage. A scenario that moves from 73% to 74% still rounds to 70%, but it is closer to the next boundary. A scenario that moves from 74% to 75% changes the final rating to 80%. The raw value explains that difference.
The same idea applies near 95%. A modeled result of 94% raw can feel close to 100%, but the final rounded result remains 90%. A modeled result of 95% raw reaches 100%. If you are studying possible outcomes, the raw number tells you whether the scenario actually crossed the final rounding threshold.
Scenario notes for paired conditions
For paired extremities or paired skeletal muscles, scenario notes should say whether each side is already compensable or only proposed. The bilateral factor depends on compensable left-and-right paired entries. If one side is currently 0% and the other side is 10%, the current audit does not receive a bilateral factor from that pair. A modeled scenario might receive the factor if the 0% side becomes compensable.
Clear separation rule
Keep one calculator run for current assigned ratings and a separate run for each scenario. That habit makes the result easier to explain, easier to verify, and less likely to be mistaken for an official combined evaluation.
Frequently Asked Questions
Is this VA disability rating calculator official?
No. This calculator is an educational tool that estimates combined VA disability ratings from the ratings you enter. Always compare the result with your VA decision letter, VA.gov account, or help from an accredited representative before relying on it for a claim or appeal.
Why does my combined VA rating not equal the ratings added together?
VA combines ratings under the whole person method. Each new percentage is applied to the efficient part that remains after earlier ratings, so 50% plus 30% becomes 65% before final rounding, not 80%.
What ratings can I enter?
Use VA-style percentages from 0% through 100% in 10% increments. The calculator accepts 0% ratings so you can keep a complete list, but 0% entries do not change the combined value or trigger a bilateral factor.
How does the calculator handle the bilateral factor?
If you mark compensable left-and-right paired extremity or paired skeletal muscle entries, the calculator combines those paired ratings, adds 10% of that paired subtotal, then treats the result as one rating before combining the rest.
Can a bilateral factor make my final VA rating lower?
Federal rules include a most-favorable principle for bilateral calculations. This calculator tests eligible paired subsets and keeps the combined result that produces the highest final rounded evaluation from the entries you provide.
Does this calculator estimate monthly VA compensation?
Yes. The result panel estimates monthly compensation from the 2026 VA table after the combined rating is calculated. The amount changes when you select a spouse, dependent children, dependent parents, or SMC(k) awards, but it remains an educational estimate.
What does raw combined value mean?
The raw combined value is the whole-number combined percentage before VA final rounding to the nearest 10%. For example, a raw value of 74% rounds to 70%, while 75% rounds to 80%.
Should I include ratings that are still pending?
Only include ratings if you want to model a possible outcome. Pending claims are not official assigned ratings yet, so a calculator estimate cannot confirm what VA will decide or when a decision will be effective.
Why is 95% rounded to 100%?
VA final rounding converts the combined value to the nearest number divisible by 10, with values ending in 5 adjusted upward. That means 95% through 100% become a 100% combined rating.
Final Thoughts
A VA disability rating calculator is most useful when it makes the combination process visible. The final rounded rating is important, but the raw combined value, remaining efficiency, bilateral factor note, and combination order explain why the final number appears. That explanation is often more helpful than a single percentage by itself.
Use the tool calmly and carefully. Enter only the ratings you mean to test, mark paired left-and-right conditions only when appropriate, and compare the estimate with official VA records. The math can clarify a combined rating, but the facts behind each rating still come from VA decisions, evidence, and qualified review.
