Why VA Disability Math Isn't Normal Math (50% + 30% != 80%)

How the VA actually combines your ratings, why two 50s don't make 100, and a free calculator that does it for you.

  • The VA combines ratings using 'whole person' math — each rating applies only to the ability you have left, not a simple sum.
  • Example: 50% then 30% combines to 65% (rounded), not 80% — order and rounding both matter.
  • Our free combined-rating calculator shows the real number and the step-by-step math.
  • For the actual claim — evidence, secondary conditions, appeals — VetAid.ai is purpose-built to do the heavy lifting.

Frequently asked

Is 50% plus 30% equal to 80% for VA disability?

No. The VA uses combined-ratings math, so 50% and 30% combine to about 65% (rounded), not 80%. Use our calculator for your exact number.
