The step-by-step math
- Start with the higher rating: 80%. You're considered 20% efficient.
- Apply the 80% rating to the remaining 20%: 80% × 20 = 16 additional points.
- Combined value: 80 + 16 = 96 — exactly what the §4.25 Table I shows for 80 and 80.
- Round to the nearest 10 (§4.25(a)): 96 → 100%.

Frequently asked questions
What is 80% + 80% VA disability?
80% combined with 80% is a combined value of 96, which rounds to a 100% VA rating under 38 CFR 4.25. VA ratings combine rather than add: the 80% rating applies only to the 20% efficiency remaining after the 80% rating.
Why isn't 80% + 80% equal to 160%?
Because 38 CFR 4.25 combines ratings against your remaining efficiency. Starting at 80%, you have 20% efficiency left; the 80% rating takes 80% of that 20 (16 points), giving 96 — not 160.
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.
