How to Calculate VA Disability Ratings: A Step-by-Step Guide for 2026
If you have ever tried to add up your VA disability ratings and ended up with a headache, you have experienced the confusing reality of VA math. The VA does not use standard addition because of the “whole person theory.” This mathematical framework dictates that a veteran can never be more than 100% able-bodied. When you receive your first disability rating, it is subtracted from your “whole” healthy self. Any subsequent ratings you receive are not taken from your original 100% starting point; instead, they are calculated as a percentage of your remaining healthy efficiency.
