VA combined rating calculator
VA doesn’t add ratings together. It combines them with the table in 38 CFR 4.25, so 50% and 30% make 70%, not 80%. Enter each rating to see the math step by step.
Choose at least one rating to see your combined rating.
How VA combines ratings
- Put the ratings in order, highest first.
- Start with the highest. Each next rating applies only to the part of you that isn’t already rated: 30% of the remaining 50 adds 15, so 50 becomes 65.
- Each step is a whole number (a half rounds up), and that number is used for the next step.
- The final value rounds to the nearest 10, with values ending in 5 rounding up: 65 becomes 70%, 64 becomes 60%.
The bilateral factor
- When conditions affect both arms, both legs, or matching muscles on both sides, 38 CFR 4.26 combines those ratings first and adds 10% of that value.
- Example: 40% left knee and 20% right knee combine to 52. Adding 5.2 makes 57, which is then combined with your other ratings.
- If you have bilateral ratings on both arms and both legs, they all go into one group.
- This calculator uses VA’s usual method. In unusual cases VA can arrange the group differently, so your rating decision is the final word.
Good to know
- 0% ratings don’t change the combined rating, but they still matter if the condition gets worse.
- A combined rating doesn’t include special monthly compensation, which is paid on top. See how SMC works.
- Your pay depends on the rounded rating and your dependents. See the VA disability rate tables.
- This is an estimate from the numbers you enter, not a VA decision.
