Question 1

What is 40 and 30% VA disability combined?

Accepted Answer

40 and 30% combines to a 60% VA disability rating (58% before rounding to the nearest 10%), not 70%. The VA uses whole-person math: each rating only applies to the portion still healthy after the previous one. A 60% rating pays $1,435/month in 2026 for a veteran alone.

Question 2

Why isn't 40 and 30 equal to 70%?

Accepted Answer

Because the VA never adds ratings. After a 40% rating, only 60% of the "whole person" is left, so the next rating applies to that smaller amount. This always yields less than the simple sum, capped at 100%.

40 and 30% VA Disability = 60%
