VA math is not regular math.

Adding 30% + 20% does not equal 50% in VA world. The VA applies each rating to what's left of your “whole person.” The real number is always lower than you think.

Your disability ratings

One per condition

Bilateral factor applies

Check this if you have ratings for both arms, both legs, or one arm + one leg — the VA adds 10% of your combined value before rounding.

What this calculator can't do

·This shows what your rating should be — not what the VA assigned. If your combined rating seems wrong, request your C-file (all your VA records) and verify.
·Dependent rates are higher. If you have a spouse, children, or dependent parents, your monthly compensation is more than shown above.
·Special Monthly Compensation (SMC) applies in specific situations — loss of use of limbs, need for regular aid and attendance, and others. SMC can pay significantly more than 100%.
·If you think you're underrated, you can file a Supplemental Claim, Higher-Level Review, or appeal to the Board of Veterans' Appeals.

How ratings work

Full explanation at va.gov

This calculator uses the official VA combined ratings formula (38 CFR Part 4). Pay rates are 2025 estimates for a single veteran with no dependents. Always verify your actual rating and compensation at va.gov or through a VSO.
