The step-by-step math
- Start with the higher rating: 100%. You're considered 0% efficient.
- Apply the 50% rating to the remaining 0%: 50% × 0 = 0 additional points.
- Combined value: 100 + 0 = 100 — exactly what the §4.25 Table I shows for 100 and 50.
- Round to the nearest 10 (§4.25(a)): 100 → 100%.

Frequently asked questions
What is 100% + 50% VA disability?
100% combined with 50% is a combined value of 100, which rounds to a 100% VA rating under 38 CFR 4.25. VA ratings combine rather than add: the 50% rating applies only to the 0% efficiency remaining after the 100% rating.
Why isn't 100% + 50% equal to 150%?
Because 38 CFR 4.25 combines ratings against your remaining efficiency. Starting at 100%, you have 0% efficiency left; the 50% rating takes 50% of that 0 (0 points), giving 100 — not 150.
How much does a 100% rating pay?
Effective 2025-12-01, 100% pays $3,938.58 per month for a veteran with no dependents, or $4,158.17 with a spouse, per the va.gov rate tables.
