VA Disability Calculator
Enter your service-connected ratings and this figures your combined VA disability rating the way the VA actually does it: combining, not adding, then rounding to the nearest 10. It also applies the bilateral factor for paired-limb conditions.

Combined ratings calculator
Enter each of your service-connected ratings. This runs the VA's own method (38 CFR § 4.25), applies the bilateral factor (§ 4.26) where you mark it, and rounds to the nearest 10.
Add them one at a time. Order doesn't matter, the calculator sorts them for you.
Estimate only. It runs the VA's combined-ratings method (§ 4.25) and the bilateral factor (§ 4.26), but not Special Monthly Compensation or TDIU. Your official rating comes from the VA. To turn a rating into a monthly dollar figure, see the 2026 rate tables.
How the math works
The VA doesn't add your ratings together, because a person can't be more than 100% disabled. It starts you at 100% efficient and each rating takes a bite out of what's left, not out of the original 100. That's why a 50% and a 30% come out to 70%, not 80%. For the full walkthrough, worked examples, and the rounding rule, read the Combined Ratings guide.
Estimate only, not an official rating. This tool uses the VA's combined-ratings method (38 CFR § 4.25) and the bilateral factor (§ 4.26); it does not include Special Monthly Compensation or TDIU, and it can't account for every case.
