VA Disability Ratings Calculator
Understanding how multiple VA disability ratings combine can be confusing because VA disability percentages are not simply added together. A Veteran with several individual ratings may receive a combined rating that is lower than the arithmetic sum of those percentages.
The VA Disability Ratings Calculator helps estimate a combined disability rating by applying each disability to the Veteran’s remaining level of efficiency. It then rounds the resulting combined percentage to the nearest 10% and uses compensation-rate assumptions to estimate monthly and annual payments.
The calculator also includes inputs for a spouse and dependents so you can see how those selections affect the estimated compensation.
For current benefit planning, it is important to compare calculator results with the official VA compensation tables because VA payment rates and dependent rules can change. VA’s current 2026 compensation tables are effective December 1, 2025.
What Is a VA Disability Ratings Calculator?
A VA Disability Ratings Calculator is a tool designed to estimate how multiple individual disability ratings may combine into a single overall VA disability rating.
For example, if a Veteran has disability ratings of 50% and 30%, the ratings are not simply added to produce 80%. VA uses a combined-ratings method in which the second disability is applied to the remaining portion of the Veteran’s efficiency. VA explains that multiple ratings are combined using the “whole person” concept rather than simple addition.
This calculator accepts up to five individual disability ratings.
It calculates:
- Combined disability rating before rounding
- Rounded VA disability rating
- Estimated monthly compensation
- Estimated annual compensation
- Spouse allowance
- Dependent allowance
How to Use the VA Disability Ratings Calculator
Using the calculator requires entering your individual disability percentages and dependent information.
1. Enter Your Disability Ratings
Enter each individual disability rating into the available fields.
You can enter up to five ratings:
- Disability Rating 1
- Disability Rating 2
- Disability Rating 3
- Disability Rating 4
- Disability Rating 5
Only ratings greater than 0 are included in the calculation.
For example, you might enter:
- 50%
- 30%
- 20%
The calculator then sorts the ratings from highest to lowest before combining them.
2. Select Your Spouse Status
Choose whether you have a spouse.
The calculator provides:
- No
- Yes
The calculator applies a spouse allowance only when the resulting rounded rating is at least 30%.
VA likewise states that additional compensation for qualifying dependents may be available when a Veteran has a combined disability rating of at least 30%.
3. Enter the Number of Dependents
Enter the number of dependents you want to include.
The calculator uses this number to estimate a dependent allowance when the rounded disability rating is at least 30%.
However, actual VA compensation depends on the type and eligibility of each dependent. VA’s official tables distinguish between spouses, children, parents, children of different ages, and other circumstances.
4. Calculate Your Results
Select Calculate to display the results.
The calculator provides your estimated:
- Combined rating
- Rounded rating
- Monthly compensation
- Annual compensation
- Spouse allowance
- Dependent allowance
How VA Disability Ratings Are Combined
The most important concept to understand is that VA disability ratings are not additive.
Instead, each additional disability is applied to the remaining percentage of the Veteran who is not already considered disabled.
The basic calculation used by this calculator is:
Combined Rating = Existing Combined Rating + (Next Rating × Remaining Percentage ÷ 100)
Where:
Remaining Percentage = 100 − Existing Combined Rating
This process is repeated for each additional disability.
VA’s official explanation confirms that multiple ratings are combined using the combined ratings table, with the highest rating considered first and additional ratings applied sequentially.
Why VA Ratings Are Not Added Together
Suppose a Veteran has:
- 60% disability
- 30% disability
Adding the ratings directly would produce 90%.
However, the second 30% rating is not applied to the entire original 100%. It is applied to the remaining 40%.
So:
60% disability leaves 40% efficiency
Then:
30% of 40 = 12
The combined value becomes:
60 + 12 = 72%
The final rating is then rounded according to VA’s combined-rating process.
This is why the combined rating differs from simply adding individual percentages.
VA provides similar examples in its official combined-ratings information.
Why Ratings Are Sorted From Highest to Lowest
The calculator sorts the disability ratings from largest to smallest before performing its calculations.
For example, if you enter:
- 20%
- 60%
- 30%
The calculator processes them as:
60%, 30%, 20%
This follows the general structure of VA’s combined-rating methodology, where disabilities are arranged from the greatest to the least before combination.
How the Calculator Handles Multiple Ratings
Suppose you have three ratings:
60%, 30%, and 20%
First Rating
Start with:
60%
Second Rating
The remaining percentage is:
100 − 60 = 40%
Apply the 30% disability to the remaining 40%:
30% × 40% = 12%
Combined:
60 + 12 = 72%
Third Rating
Now there is:
100 − 72 = 28%
remaining.
Apply the 20% rating:
20% × 28% = 5.6%
New combined rating:
72 + 5.6 = 77.6%
The calculator displays the unrounded result as:
77.60%
It then rounds the result to the nearest 10%:
80%
VA’s official example using 60%, 40%, and 20% produces an exact combined value of 81% before the final rounding to 80%.
Understanding the Rounded VA Rating
The calculator uses:
Rounded Rating = nearest 10%
For example:
| Combined Value | Rounded Result |
|---|---|
| 42% | 40% |
| 47% | 50% |
| 53% | 50% |
| 55% | 60% |
| 64% | 60% |
| 65% | 70% |
| 77% | 80% |
| 84% | 80% |
VA explains that the final combined value is converted to the nearest degree divisible by 10.
This final rounding step is important because compensation rates are tied to the final disability percentage.
VA Disability Compensation and Dependents
A Veteran’s compensation can depend not only on the disability rating but also on eligible dependents.
VA states that Veterans with a combined disability rating of at least 30% may qualify for additional compensation for qualifying spouses, children, and dependent parents.
The actual payment structure is more detailed than simply multiplying the number of dependents by one universal allowance.
For example, VA’s current 2026 rate tables distinguish among:
- Veteran alone
- Veteran with a spouse
- Veteran with children
- Veteran with a spouse and children
- Veteran with dependent parents
- Additional children
- Certain children over age 18
- Spouses receiving Aid and Attendance
The official tables should therefore be used to verify a payment amount.
VA Disability Compensation Rates
The compensation figures built into this calculator should not be treated as current official VA payment rates.
For 2026, VA lists basic monthly compensation for a Veteran without dependents at:
| Rating | 2026 Monthly Rate |
|---|---|
| 10% | $180.42 |
| 20% | $356.66 |
| 30% | $552.47 |
| 40% | $795.84 |
| 50% | $1,132.90 |
| 60% | $1,435.02 |
| 70% | $1,808.45 |
| 80% | $2,102.15 |
| 90% | $2,362.30 |
| 100% | $3,938.58 |
These are the current VA rates effective December 1, 2025.
The calculator’s embedded compensation amounts are different from these current official figures. For example, the calculator uses $171.23 for 10%, while VA’s current 2026 table lists $180.42. Therefore, the calculator’s compensation output should be treated as an estimate based on its built-in rates, not as a current official payment quote.
VA Disability Calculator Example
Suppose a Veteran enters:
| Disability | Rating |
|---|---|
| Rating 1 | 60% |
| Rating 2 | 30% |
| Rating 3 | 20% |
| Rating 4 | — |
| Rating 5 | — |
The calculator sorts the ratings as:
60%, 30%, 20%
Start with the highest rating:
60%
Remaining efficiency:
100 − 60 = 40%
Apply the 30% rating:
30% × 40% = 12%
Combined:
60 + 12 = 72%
Remaining efficiency:
100 − 72 = 28%
Apply the 20% rating:
20% × 28% = 5.6%
Final unrounded result:
77.6%
Rounded result:
80%
The calculator would therefore display a 77.60% combined rating and an 80% rounded rating.
VA Combined Rating vs. Simple Addition
It is useful to compare the two approaches.
Using the example above:
60 + 30 + 20 = 110%
Simple addition produces 110%, which cannot represent the VA combined rating.
The calculator’s whole-person-style calculation produces:
77.6%
After rounding:
80%
This illustrates why Veterans should not calculate their combined VA rating by simply adding their individual percentages.
VA specifically explains that disability ratings are not additive and provides a combined-ratings table for calculating multiple disabilities.
Why a 100% Combined Rating Is Different
A Veteran can have several individual disability ratings that combine to a value approaching 100% without reaching exactly 100%.
For example, successive ratings are applied to increasingly smaller portions of remaining efficiency.
This means additional ratings can have a smaller numerical effect as the combined rating gets higher.
The final VA rounding process can also affect the rating that determines the compensation level.
Understanding the “Whole Person” Concept
The VA combined-rating method is often described through the concept of the “whole person.”
Rather than treating each disability as if it applies to a separate 100% person, the method recognizes that a Veteran’s first disability already reduces the remaining efficiency.
For example, after a 60% disability, the remaining efficiency is 40%. A later 20% disability is therefore applied to that remaining 40%, rather than to the original 100%.
This approach prevents multiple disabilities from being added directly to more than 100%.
Are VA Disability Payments Taxable?
VA disability compensation is generally a federal tax-free benefit. However, individual financial situations can involve other considerations, so Veterans should verify their specific circumstances using authoritative federal guidance.
The calculator itself does not calculate federal, state, or local tax treatment.
Why Calculator Results May Differ From Your VA Award
A calculator can provide a mathematical estimate, but your official VA rating and compensation can depend on factors that a basic calculator does not capture.
These may include:
- The actual disability ratings assigned by VA
- Bilateral factor considerations
- Special Monthly Compensation
- Dependent eligibility
- Additional dependent categories
- Aid and Attendance
- Effective dates
- Other compensation adjustments
- Current VA payment tables
VA also determines disability ratings based on evidence, including medical evidence and, when applicable, the results of a VA claim examination.
For that reason, a calculator should be used as an educational planning tool rather than as a substitute for an official VA determination.
Frequently Asked Questions
1. What is a VA Disability Ratings Calculator?
A VA Disability Ratings Calculator estimates how multiple individual disability percentages combine into an overall VA disability rating and can provide an estimated compensation amount.
2. Can I simply add my VA disability ratings together?
No. VA generally uses a combined-ratings method rather than simple addition. Each additional disability is applied to the remaining percentage of efficiency.
3. Why does my combined rating differ from the sum of my ratings?
Because VA combines disabilities sequentially rather than adding the percentages directly. A second disability is applied to the portion of the Veteran not already considered disabled.
4. Does the order of disability ratings matter?
The ratings are arranged from highest to lowest for the combined-rating calculation. The calculator automatically sorts the entered ratings in descending order.
5. How many disability ratings can this calculator combine?
This calculator accepts up to five individual disability ratings.
6. How does VA round a combined disability rating?
The final combined value is rounded to the nearest 10%. VA describes this as converting the final combined value to the nearest degree divisible by 10.
7. When can dependents affect VA compensation?
VA states that qualifying Veterans with a combined disability rating of at least 30% may receive additional compensation for eligible dependents.
8. Does having a spouse automatically add the same amount at every rating?
No. Dependent compensation varies according to the disability rating and the Veteran’s specific dependent circumstances. Current VA tables contain different rates for different family situations.
9. Does the calculator use current VA compensation rates?
The compensation figures built into this calculator are fixed values and do not match the current 2026 VA rate table. Current payment amounts should be verified against the official VA rates.
10. What is the difference between combined rating and rounded rating?
The combined rating is the calculator’s calculated percentage before final rounding. The rounded rating is the percentage after rounding to the nearest 10%.
11. Can two 10% disabilities equal 20%?
Not under the VA combined-rating method. VA gives the example that two 10% disabilities combine to 19% before the final rounding process.
12. Can a Veteran have a combined rating above 100%?
The VA combined-rating system does not produce a final rating above 100%. Individual ratings are combined using the remaining-efficiency method and the final result is rounded within the VA rating scale.
13. Does this calculator include every VA compensation adjustment?
No. It is a simplified calculator. Factors such as special monthly compensation, bilateral-factor rules, specific dependent categories, and other adjustments may affect an actual VA payment.
14. Where can I find official VA disability compensation rates?
The official VA compensation-rate tables provide current payment amounts based on disability rating and dependent status. VA’s current 2026 tables are available through its disability compensation rates page.
15. Is this calculator an official VA determination?
No. It is an estimating tool. Your official disability rating and compensation amount are determined by the Department of Veterans Affairs based on applicable rules, evidence, ratings, and current benefit tables.
Final Thoughts
A VA Disability Ratings Calculator can make the combined-rating process easier to understand, particularly when you have multiple individual disability percentages.
The key concept is that VA ratings are not simply added together. Instead, disabilities are combined using a remaining-efficiency approach, with the final result rounded to the nearest 10%.
The calculator can also provide a useful estimate of compensation based on its built-in assumptions. However, its compensation figures are not the current 2026 VA rates, so Veterans should verify payment amounts against the official VA tables before using them for financial planning.
Dependent compensation is also more detailed than the calculator’s simplified spouse and dependent allowances. VA’s official tables account for different family circumstances, including spouses, children, parents, and certain special situations.
For the most reliable result, use your official VA disability ratings and current VA compensation tables when determining your actual benefits.
