Combined ratings table
Each new rating combines with the existing combined value using a table in regulations. Online calculators mirror this process for planning.
Why it exists
The model reflects diminishing combined impact of multiple impairments on earning capacity.
Bilateral factor
When both sides of the body qualify under specific rules, an extra adjustment may apply before final combination.
A worked example
VA does not add ratings. Say you have a 50 percent rating and a 30 percent rating. Start with the higher one, 50 percent, which leaves 50 percent of whole-body capacity. Apply the 30 percent rating to that remainder: 30 percent of 50 is 15. Add it back to get 65 percent, then round to the nearest 10 percent for a 70 percent combined rating. The combined ratings table in 38 CFR 4.25 performs this calculation, and the bilateral factor in 38 CFR 4.26 can add a step when paired limbs (both arms or both legs) are involved.
