The VA doesn't add ratings together. They use “whole person” math — and it almost always results in a lower number than you'd expect. See how yours works.

With a combined rating of 80%, if your disabilities prevent you from holding a steady job, you may qualify for TDIU — which pays at the 100% rate ($3,737/month). Ask a VSO whether this applies to you.

The VA uses what's called “whole person” math. Instead of adding your ratings together, the VA treats each disability as reducing what's left of a “whole person.”
For example: if you have a 70% rating, VA considers you 30% “whole.” A second 50% disability takes 50% of that remaining 30% — not 50% of 100%. So your combined rating is 70% + 15% = 85%, which rounds to 90% — not 120%.
This is why veterans with multiple significant disabilities often find their combined rating lower than expected. Understanding this math matters when deciding which conditions to claim and how to prioritize your evidence.
