Why VA ratings do not add up
The VA combines ratings using the combined ratings table in 38 C.F.R. § 4.25. Each rating applies to the “efficiency” left after the higher ratings. A 50% rating leaves 50% efficiency; a 30% rating applied to that takes 15 more, for a combined 65%, not 80%.
Rounding
After combining, the VA rounds the result to the nearest 10. Values ending in 5 round up, so 65% becomes 70% and 64% becomes 60%.
The bilateral factor
When you have ratings on both arms or both legs, the VA combines those first, then adds 10% of that value before combining with your other ratings (38 C.F.R. § 4.26). Tick “Bilateral” for those ratings.
Monthly payment
Your monthly compensation depends on your combined rating and dependents. The VA publishes the current rate tables each December at va.gov.
