What do 80% and 50% VA disability ratings combine to?
80% and 50% disability ratings combine to 90%, which is already a multiple of ten, so the combined rating is 90%. They do not add up to 130%, because each rating applies only to the part of the body that is still considered healthy.
VA does not add ratings together. It combines them using the table in 38 CFR §4.25, starting with the most severe and applying each next rating to whatever percentage remains. This page shows that arithmetic step by step for 80% and 50%.
Step by step
| Step | Rating applied | Applied to | Running total |
|---|---|---|---|
| 1 | 80% | the starting rating | 80% |
| 2 | 50% | 20% still healthy | 90% |
The combined value of 90% is already a multiple of ten, so §4.25 leaves it unchanged at a 90% combined rating.
Monthly compensation at 90%
These are the published VA rates for a 90% combined rating, effective December 1, 2025. The amount depends on dependents, and other factors can change it, so treat these as the table figures, not as a statement about any individual payment.
| Veteran alone | $2,362.30 |
| With spouse | $2,559.30 |
| Spouse + 1 child | $2,704.30 |
| With spouse and two parents | $2,875.30 |
What a 90% rating may open up
A combined rating is the key that federal programs check. See the programs a 90% combined rating may make a veteran eligible for, each with its official citation and the agency that decides it, on the 90% benefits page.
Where this can differ from a real decision
This page combines the numbers in its own URL. A real decision letter can differ for reasons the arithmetic alone does not show: paired limbs add the bilateral factor before the rest is combined, some conditions cannot be rated separately because of pyramiding, and effective dates can mean different ratings applied at different times.
To see the arithmetic on the conditions in your own letter, including the bilateral factor where it applies, you can decode your rating letter, or try other numbers in the combined rating calculator.
