Get Your Personal CalculatorSee how different military backgrounds and conditions combine for VA ratings:
The VA uses a combined rating table to calculate your overall disability percentage. This isn't simple addition - a 70% rating plus a 30% rating doesn't equal 100%. Instead, the VA considers that each additional condition affects the remaining "whole person."
For example, if you have a 70% rating, the VA considers you 30% "whole." A second condition rated at 30% would affect 30% of that remaining 30%, adding 9% to your total for a combined rating of 79%, which rounds to 80%.
Keep detailed records of all symptoms, medical visits, and how conditions affect your daily life.
Have fellow service members document incidents and symptoms they witnessed during service.
Many conditions cause other problems. PTSD can lead to sleep disorders, back injuries can cause depression.
