How VA Disability Ratings Work

Understanding VA Ratings

VA disability ratings determine how much compensation you receive each month. Ratings range from 0% to 100% and are based on how much your service-connected conditions impact your ability to work and function.

The VA Rating Formula

The VA does not simply add percentages together. Instead, they use a "combined ratings" formula that calculates how each condition affects your remaining efficiency.

Example

If you have a 50% rating, the VA considers you 50% disabled and 50% efficient. If you then receive a 30% rating, it applies to the remaining 50% efficiency:

30% of 50% = 15%
50% + 15% = 65%
Rounded to the nearest 10 → 70%

If you'd rather not do this math by hand, the Veteran Benefits Toolkit includes a combined ratings calculator that does it for you.

What Affects Your Rating?

1. Severity of Symptoms

The VA uses diagnostic criteria to determine how severe your condition is.

2. Medical Evidence

C&P exams, private medical opinions, and treatment records all play a major role.

3. Impact on Daily Life

The VA considers how your condition affects work, mobility, mental health, and daily tasks.
