The step-by-step math
- Start with the higher rating: 70%. You're considered 30% efficient.
- Apply the 30% rating to the remaining 30%: 30% × 30 = 9 additional points.
- Combined value: 70 + 9 = 79 — exactly what the §4.25 Table I shows for 70 and 30.
- Round to the nearest 10 (§4.25(a)): 79 → 80%.
What 80% pays
Effective 2025-12-01: $2,102.15/month for a veteran alone, $2,277.15 with a spouse, $2,406.15 with spouse and one child. Full dependent tables: 80% pay page.
What a third rating would do
| Add | Combined value | Final rating |
|---|---|---|
| +10% | 81 | |
| +20% | 83 | |
| +30% | 85 | |
| +40% | 87 | |
| +50% | 90 |
Notice how each added rating moves the needle less — that's the combining math working against you as the numbers climb. Model your exact set of ratings.
Frequently asked questions
What is 70% + 30% VA disability?
70% combined with 30% is a combined value of 79, which rounds to a 80% VA rating under 38 CFR 4.25. VA ratings combine rather than add: the 30% rating applies only to the 30% efficiency remaining after the 70% rating.
Why isn't 70% + 30% equal to 100%?
Because 38 CFR 4.25 combines ratings against your remaining efficiency. Starting at 70%, you have 30% efficiency left; the 30% rating takes 30% of that 30 (9 points), giving 79 — not 100.
How much does a 80% rating pay?
Effective 2025-12-01, 80% pays $2,102.15 per month for a veteran with no dependents, or $2,277.15 with a spouse, per the va.gov rate tables.
