VA Combined Rating Calculator

VA ratings don't add — they combine. This calculator runs the actual regulation: the §4.25 combined ratings table, the §4.26 bilateral factor, and the rounding rule, with every step shown and every number sourced.

How the math works

Under 38 CFR §4.25, ratings are combined from most to least severe. Each new rating applies only to the “efficiency” you have left. With a 50% rating you are considered 50% efficient; a second, 30% rating takes 30% of the remaining 50 — that is 15 more points, for a combined value of 65, which rounds to 70%.

The §4.26 bilateral factor applies when both arms or both legs are affected: those ratings combine first, gain 10% of their combined value, and the result is treated as a single disability.

Frequently asked questions

How does the VA combine multiple disability ratings?

The VA does not add ratings. Under 38 CFR 4.25, ratings are combined: starting from the highest rating, each additional rating applies only to the "remaining efficiency." For example, 50% combined with 30% is 65 (50 + 30% of the remaining 50), which rounds to a 70% combined rating.

What is the bilateral factor?

Under 38 CFR 4.26, when you have disabilities affecting both arms or both legs (or paired skeletal muscles), those ratings are combined first and 10% of that combined value is added before combining with your other ratings.

How is the final rating rounded?

Under 38 CFR 4.25, the final combined value is rounded to the nearest 10%. A combined value of 65 rounds to 70%; a combined value of 64 rounds to 60%.

Do dependents change the rating itself?

No. Dependents do not change your combined rating. At ratings of 30% or higher, dependents increase the monthly compensation amount, per the VA compensation rate tables.
