VA Disability Calculator

Use this VA Disability Calculator to estimate a combined VA disability rating from multiple service-connected ratings and see the corresponding 2026 monthly compensation amount. The calculator follows the VA combined-rating method rather than simply adding percentages together, and it can also account for qualifying bilateral disabilities involving both arms, both legs, or paired skeletal muscles.

After entering your individual ratings, you can add a spouse, dependent parents, children under age 18, qualifying school-age children, and spouse Aid and Attendance when applicable. The result shows the raw combined value, the final rounded VA rating, an estimated monthly payment, and an annual compensation estimate using the current 2026 VA compensation tables.

How to Use the VA Disability Calculator

Enter each individual service-connected disability rating separately. If you have a 50% rating for one condition, a 30% rating for another, and a 10% rating for a third, enter 50, 30, and 10 in three separate rows. Do not add the ratings together before entering them.

For each condition, leave the body location set to Other unless the rating is for a qualifying left or right arm, left or right leg, or paired skeletal muscle. The location field is used only to test whether the bilateral factor may apply. It is not asking you to enter a diagnosis.

Next, enter your dependent information. Dependents do not increase the standard monthly compensation rate at 10% or 20%, but they can affect the payment at ratings of 30% and higher. The calculator can account for a spouse, up to two dependent parents, children under 18, children age 18 to 23 in a qualifying school program, and a spouse who receives Aid and Attendance.

The result shows four useful numbers: the final rounded combined rating, the raw combined value before final rounding, the estimated monthly payment, and the estimated annual amount. It also tells you whether a bilateral factor was applied.

How VA Disability Ratings Work

The Department of Veterans Affairs assigns disability ratings in percentages based on the severity of service-connected conditions. Individual evaluations are generally assigned under the VA Schedule for Rating Disabilities. A rating represents the degree to which a service-connected condition is considered disabling under the applicable criteria.

A Veteran can have one service-connected disability or many separate disabilities. When there is more than one compensable rating, VA does not normally add the percentages together. Instead, VA combines them using the Combined Ratings Table in 38 CFR §4.25.

This distinction is one of the most confusing parts of VA disability compensation. Two 50% ratings do not equal a 100% combined rating. A 50% disability leaves 50% of the whole person remaining. The next 50% rating applies to that remaining 50%, which adds 25 percentage points. The combined value is therefore 75%, which becomes an 80% final combined rating after VA rounding.

If you only need to check a percentage calculation outside the VA system, our Percentage Calculator can help with ordinary percentage math. VA combined-rating math, however, follows its own whole-person method.

How VA Math Combines Multiple Ratings

The phrase “VA math” is commonly used to describe the whole-person calculation. VA starts with the highest individual rating and then applies the next-highest rating to the percentage of the person that remains unaffected.

Suppose the first disability is 60%. That leaves 40% of the whole person remaining. A second disability rated 30% is applied to that remaining 40%, which contributes 12 additional percentage points. The new combined value is 72% rather than 90%.

If there is another 20% rating, that rating applies to the 28% of the whole person remaining after the 72% combined value. Twenty percent of 28 is 5.6, producing approximately 78% after the VA table’s whole-number step. The final combined value is then rounded to the nearest 10%.

VA instructs that ratings are arranged from highest to lowest. Each additional rating is combined with the current combined value. The final value is converted to the nearest degree divisible by 10. Values ending in 1 through 4 round down, while values ending in 5 through 9 round up.

The Whole Person Theory

The whole-person approach prevents a combined disability percentage from mathematically exceeding 100%. Each new disability affects only the portion of the person that has not already been accounted for by higher ratings. If you want to check the arithmetic outside the VA table, the Simple Math Calculator can help with the individual multiplication and subtraction steps.

This is why additional ratings have a smaller numerical effect when the combined value is already high. At 20% combined, there is 80% efficiency remaining. At 90% combined, only 10% remains. A new 10% disability applied to that remaining 10% adds only about one point before rounding.

The whole-person system also explains why moving from a 90% final rating to 100% can be difficult. A Veteran shown as 90% could have a raw combined value anywhere from 85% through 94%. Someone sitting at 94% is much closer to the 95% threshold that rounds to 100% than someone at 86%.

Combined VA Rating Examples

50% and 30%

A 50% rating leaves 50% remaining. Thirty percent of the remaining 50 is 15. Add that to 50 and the combined value is 65. VA rounds 65 to 70%, so the final combined rating is 70%.

40% and 20%

A 40% rating leaves 60% remaining. Twenty percent of 60 is 12. The combined value becomes 52%, which rounds to a final rating of 50%.

60%, 40%, and 20%

VA’s published example combines 60 and 40 to 76. The 20% rating is then combined with 76 to produce 81. A raw combined value of 81 rounds to 80%.

Two 10% Ratings

Two ordinary 10% ratings combine to 19%. That final value rounds to 20%. If those two 10% ratings qualify for the bilateral factor, the calculation may be different because the bilateral adjustment is applied before the final combination process.

Why Individual Ratings Should Be Entered Separately

A common mistake is to take several disability percentages, add them by hand, and enter the sum into a calculator. That produces the wrong result because it skips the whole-person calculation.

Enter each rating exactly as a separate evaluation. The order does not matter in the form because the calculator sorts them from highest to lowest before combining them.

VA Bilateral Factor

The bilateral factor is an additional calculation under 38 CFR §4.26. It can apply when compensable service-connected disabilities affect both arms, both legs, or paired skeletal muscles. The rule recognizes that disabilities affecting both sides of a paired set of extremities can create additional overall impairment.

The bilateral factor is often misunderstood as a flat 10% disability rating. It is not. VA first combines the qualifying bilateral ratings using normal VA math. It then adds 10% of that bilateral combined value arithmetically before the bilateral group is combined with the Veteran’s other ratings.

For example, two qualifying 10% bilateral ratings combine to 19. Ten percent of 19 is 1.9. Adding that factor produces approximately 20.9, which is treated as about 21 for the next step of the combined-rating process.

What Counts as a Bilateral Disability?

The regulation refers to disabilities of both arms, both legs, or paired skeletal muscles. “Arm” and “leg” are used broadly for the upper and lower extremities. A compensable disability of the right knee and a compensable disability of the left ankle can potentially satisfy the paired lower-extremity requirement even though the exact joints are different.

One arm and one leg do not form a bilateral pair. A single left-knee rating alone does not receive the bilateral factor. There must be compensable disability affecting both members of the relevant pair.

The 2023 Bilateral-Factor Exception

Since April 2023, 38 CFR §4.26 includes an exception designed to avoid a lower combined evaluation caused by mandatory use of the bilateral factor. If excluding one or more bilateral disabilities from the bilateral-factor calculation would produce a higher combined evaluation, VA is supposed to use the more favorable calculation.

The calculator compares the final rounded result with and without the bilateral adjustment and does not force the bilateral result when it would produce a lower final evaluation. This matters most in unusual combinations near a rounding threshold.

2026 VA Disability Pay Rates

The current 2026 VA disability compensation rates are effective December 1, 2025. Veterans rated 10% or 20% receive the same standard rate regardless of dependent status. Additional compensation for qualifying dependents begins at a combined rating of 30%.

These are standard compensation rates. Special Monthly Compensation can produce payments above the ordinary 100% table, and some Veterans may have adjustments related to military retired pay, severance pay, incarceration, apportionment, or other circumstances.

The official VA compensation tables should be the final reference whenever a payment amount matters. You can review the current figures directly on the VA disability compensation rates page.

VA Disability Pay With Dependents

At a combined rating of 30% or more, qualifying dependents can increase the standard monthly disability compensation payment. The VA tables include combinations involving a spouse, dependent parents, and children.

The first child under 18 is built into the applicable “with one child” base table. Additional children under 18 receive an added monthly amount based on the Veteran’s combined rating. A qualifying child age 18 to 23 who is attending an approved school program is handled through a separate added amount.

A spouse who qualifies for Aid and Attendance can also add a separate amount to the Veteran’s monthly compensation. That addition depends on the Veteran’s combined disability rating.

2026 Additional Dependent Amounts

Dependent Parents

A dependent parent can increase compensation when the Veteran’s combined rating is at least 30% and VA recognizes the parent as a dependent. The rate table distinguishes between one parent and two parents, as well as whether the Veteran also has a spouse or child.

The calculator lets you choose zero, one, or two dependent parents. This is only a payment estimate; it does not determine whether a parent meets VA dependency requirements.

Children Over 18 in School

A child can sometimes continue to count for additional VA compensation after age 18 when enrolled in a qualifying school program, generally until age 23 if the applicable requirements are met. VA publishes a separate additional amount for these school children instead of treating them exactly like a child under 18.

The calculator therefore has a separate school-child field. Do not put the same child in both fields at the same time.

100% VA Disability Pay in 2026

A Veteran with a standard 100% disability rating and no dependents receives $3,938.58 per month under the 2026 compensation table. A Veteran rated 100% with a spouse and no children receives $4,158.17 per month. Other dependent combinations can increase the amount further.

A 100% rating can be reached through a single disability rated at 100% or through multiple disabilities that combine to a final 100% evaluation. For combined ratings, a raw combined value of at least 95% rounds to 100%.

Special Monthly Compensation can exceed the standard 100% rate when separate eligibility criteria are met. The ordinary compensation table should not be treated as the maximum possible VA payment in every case.

How VA Math Goes From 90% to 100%

A final 90% rating can hide a wide range of raw combined values. Anything from 85% through 94% rounds to 90. To reach 100% through ordinary combined-rating math, the raw value generally needs to reach at least 95%.

This means the same additional rating can have very different effects for two Veterans who both appear to be rated 90%. Someone at a raw 94% may need only a small additional effective increase to cross 95. Someone at 86% needs substantially more.

For example, combining a raw value of 94 with a new 20% rating affects the remaining 6% of the whole person. Twenty percent of 6 is 1.2, producing about 95 after the table’s whole-number calculation, which can round to 100. But combining 86 with 20 adds only about three points and does not reach 95.

Why a New 10% Rating May Not Change Your Final VA Rating

As the combined percentage rises, less of the whole person remains available for each additional disability to affect. A new 10% evaluation can increase the raw combined value without changing the final rounded rating.

This is not the same as saying the 10% condition has no value. It remains a service-connected rating and may matter in future combinations, medical treatment eligibility, secondary claims, the bilateral factor, or other benefit considerations. It simply may not move the current final rounded percentage.

VA Disability Rating Calculator vs VA Disability Pay Calculator

A rating calculator answers the percentage question: how do several individual evaluations combine under VA math? A disability pay calculator takes the resulting final rating and applies the compensation table based on dependent status.

This tool does both, so it can also be used as a VA compensation calculator after the combined percentage is determined. It first calculates the estimated combined rating and then looks up the standard monthly compensation amount. Keeping those two steps separate is important because the dependent information changes payment, not the combined disability percentage itself.

VA Disability Compensation Is Different From Military Retirement Pay

VA disability compensation and military retired pay are separate benefit systems. Some Veterans can receive both subject to applicable concurrent-receipt rules, while others may have offsets or different treatment depending on the type of retirement and disability.

This calculator estimates only standard VA disability compensation. It does not calculate CRDP, CRSC, military retirement, severance recoupment, or retired-pay offsets.

TDIU vs a 100% Schedular VA Rating

Total Disability based on Individual Unemployability, commonly called TDIU, can allow an eligible Veteran to be paid at the 100% compensation rate even when the schedular combined rating is below 100%. TDIU is not calculated by simply pushing a combined rating to 100%.

Eligibility depends on service-connected disabilities, employment limitations, and applicable VA rules. This calculator does not determine TDIU eligibility. If VA has already granted TDIU, the standard payment is generally based on the 100% compensation level, subject to dependents and other applicable rules.

Special Monthly Compensation

Special Monthly Compensation, or SMC, is additional VA compensation for certain severe disabilities, combinations of disabilities, loss or loss of use, housebound status, need for Aid and Attendance, and other qualifying circumstances.

SMC uses separate statutory rate tables and letter designations. It is more complicated than the standard percentage-based compensation table. A Veteran can sometimes receive SMC in addition to or instead of the ordinary schedular amount.

Because SMC eligibility depends on more than a combined percentage, this calculator intentionally does not try to infer it from the ratings entered. The VA publishes a separate Special Monthly Compensation rate table.

VA Disability Back Pay and Effective Dates

When VA grants a claim or increases a rating, the Veteran may receive retroactive compensation based on an effective date. Back pay is not simply the current monthly rate multiplied by the number of months since a claim was filed.

Historic compensation rates can change from year to year, dependent status can change, staged ratings can apply, and VA generally pays benefits according to specific effective-date and payment-start rules. A proper back-pay calculation may therefore require several rate periods.

This calculator does not estimate retroactive benefits. It calculates the current standard 2026 monthly compensation based on the final estimated rating and dependents you enter.

Are VA Disability Benefits Taxable?

VA disability compensation is generally excluded from federal taxable income. That makes the monthly compensation figure different from an ordinary paycheck amount that is reduced by federal income tax withholding.

If you are comparing disability compensation with employment income, remember that gross wages and tax-free benefits should not be compared dollar-for-dollar without considering taxes and payroll deductions. Our Paycheck Calculator can help estimate ordinary take-home wages separately.

Can a VA Rating Be Reduced?

Some VA disability ratings can be reduced when the evidence and applicable rules support a reduction, while other ratings have procedural or time-based protections. The rules depend on factors such as how long a rating has been in effect, whether a disability has improved, and whether the evaluation is considered protected.

A calculator cannot determine whether an individual rating is protected from reduction. Use the percentages currently shown in your VA decision or rating information if you are trying to reproduce your existing combined rating.

Permanent and Total VA Disability

Permanent and Total, often abbreviated P&T, is not another percentage above 100%. It generally refers to a total disability that VA considers permanent. A Veteran can be paid at the 100% level without necessarily having a Permanent and Total designation.

P&T status can affect eligibility for certain additional benefits for the Veteran or family members, but this calculator does not determine permanent-and-total status.

VA Disability Ratings and Secondary Conditions

A secondary service-connected condition is a disability that VA recognizes as caused or aggravated by another service-connected condition. If VA grants a separate evaluation for the secondary condition, that rating can become another percentage in the combined-rating calculation.

Do not enter a possible secondary condition into the calculator as though it has already been awarded unless you are intentionally running a hypothetical scenario. The tool can show the mathematical effect of a potential rating, but it cannot predict whether VA will grant service connection or which percentage will be assigned.

Using the Calculator for a What-If VA Rating Scenario

One useful way to use a VA disability percentage calculator is to test a possible future rating. Start with your existing individual ratings, then add a hypothetical 10%, 20%, 30%, or other evaluation to see whether the final combined percentage changes.

This can explain why a proposed additional rating may or may not move the rounded combined rating. It should not be used as a prediction of a claim decision, because the actual evaluation depends on medical evidence and the rating criteria for the condition.

VA Combined Ratings Table vs Formula

The official Combined Ratings Table lists the result when one rating is combined with another. A calculator can reproduce the same logic using the whole-person formula and whole-number rounding at each step. Both methods are intended to reach the same ordinary combined value.

The table is useful when checking only two or three ratings by hand. A calculator becomes more convenient when there are many separate conditions, bilateral disabilities, or a need to test several scenarios.

You can review the VA’s explanation and combined-rating table on its disability ratings page.

Common VA Disability Calculator Mistakes

• Adding individual ratings together instead of using VA math.
• Rounding after every step to the nearest 10 instead of waiting until the final combined value.
• Treating the bilateral factor as an extra flat 10% rating.
• Marking one arm and one leg as a bilateral pair.
• Counting dependents at a 10% or 20% rating when the standard table does not add dependent compensation at those levels.
• Counting the first child twice when using the VA “with one child” base rate.
• Putting the same child in both the under-18 and school-child fields.
• Assuming a current monthly rate can be used for every month of historic back pay.
• Assuming 90% shown on a decision means the raw combined value is exactly 90.
• Assuming the calculator can determine service connection or the correct diagnostic-code percentage.

Why the Raw Combined Value Matters

The rounded rating determines the standard compensation tier, but the raw value explains how close you are to the next threshold. A Veteran at 74% and a Veteran at 65% are both paid at the 70% level, yet their next additional rating can have very different effects.

The calculator displays the raw combined value for this reason. It helps you understand the math behind the rounded result rather than showing only the final 10% increment.

VA Compensation and Retirement Planning

For a Veteran receiving long-term disability compensation, the monthly amount may become one part of a broader retirement-income plan alongside Social Security, military retired pay, a 401(k), IRA savings, or other pensions.

Our Retirement Calculator can be used separately to model retirement savings and recurring income. Veterans who also save through an employer plan can use the 401(k) Calculator for contribution and growth scenarios. Keep in mind that VA compensation, Social Security, and retirement-account withdrawals have different tax and eligibility rules.

2026 VA Pay Examples With Dependents

A Veteran rated 70% with a spouse and one child has a 2026 base monthly rate of $2,074.45. If the Veteran has two additional children under 18, each additional child adds $76, bringing the amount to $2,226.45 before any other applicable additions. If the spouse also receives Aid and Attendance, another $141 is added, producing $2,367.45.

A Veteran rated 100% with no dependents receives $3,938.58 per month. With a spouse and no children, the base rate is $4,158.17. With a spouse and one child, the base rate is $4,318.99 before additional children, school children, dependent parents, or spouse Aid and Attendance.

Why VA Disability Rates Change

VA disability compensation rates are adjusted periodically to keep benefits aligned with cost-of-living changes. That means a calculator that uses an older pay table can show the correct combined rating but the wrong monthly dollar amount.

This version uses the 2026 standard compensation table effective December 1, 2025. When VA publishes a new annual table, the dollar amounts in the calculator should be updated even though the basic combined-rating formula usually remains the same.

VA Disability Calculator Frequently Asked Questions

Final Thoughts

The key to understanding a VA combined rating is to stop thinking of the percentages as ordinary addition. VA math applies each additional disability to what remains of the whole person, then converts the final value to the nearest 10%. The bilateral factor can add another layer when qualifying disabilities affect both sides of a paired set of extremities.

Use the calculator to reproduce an existing combined rating, compare possible future scenarios, or estimate the current standard monthly compensation for your household. For an actual claim, dependency decision, TDIU question, SMC eligibility issue, or disagreement with a VA decision, rely on the official VA record and qualified assistance rather than a calculator alone.
