The step-by-step math
- Start with the higher rating: 40%. You're considered 60% efficient.
- Apply the 30% rating to the remaining 60%: 30% × 60 = 18 additional points.
- Combined value: 40 + 18 = 58 — exactly what the §4.25 Table I shows for 40 and 30.
- Round to the nearest 10 (§4.25(a)): 58 → 60%.
What 60% pays
Effective 2025-12-01: $1,435.02/month for a veteran alone, $1,566.02 with a spouse, $1,663.02 with spouse and one child. Full dependent tables: 60% pay page.
What a third rating would do
| Add | Combined value | Final rating |
|---|---|---|
| +10% | 62 | |
| +20% | 66 | |
| +30% | 71 | |
| +40% | 75 | |
| +50% | 79 |

Frequently asked questions
What is 40% + 30% VA disability?
40% combined with 30% is a combined value of 58, which rounds to a 60% VA rating under 38 CFR 4.25. VA ratings combine rather than add: the 30% rating applies only to the 60% efficiency remaining after the 40% rating.
Why isn't 40% + 30% equal to 70%?
Because 38 CFR 4.25 combines ratings against your remaining efficiency. Starting at 40%, you have 60% efficiency left; the 30% rating takes 30% of that 60 (18 points), giving 58 — not 70.
How much does a 60% rating pay?
Effective 2025-12-01, 60% pays $1,435.02 per month for a veteran with no dependents, or $1,566.02 with a spouse, per the va.gov rate tables.
