VA combined rating calculator

VA does not add ratings. Each new rating applies to what efficiency remains after higher ratings.

How VA combined ratings work

  1. Sort disabilities from highest to lowest percentage.
  2. Start with the highest rating. Each next rating multiplies the remaining efficiency (100 − combined so far).
  3. Bilateral factor: mark only the paired disabilities. Those are combined first; if two or more are bilateral, add 10% of that subtotal, then combine with non-bilateral ratings before rounding.
  4. Round to the nearest 10% for the official combined rating.

Example: 50% then 30% → 50 + (50% × 30) = 65 → rounds to 70%.

Disabilities

Mark Bilateral only for paired extremities (or paired skeletal muscles) that belong together — e.g. left knee + right knee. A back rating is usually not bilateral.

70%

VA whole-person method, then round to the nearest 10%. Bilateral ratings are combined first; 10% of that subtotal is added before combining with other disabilities.
