How VA Disability Ratings Work Explained

Multiple ratings do not add up. The VA uses what it calls the whole person theory, and the arithmetic surprises almost everyone the first time.

The logic: each rating describes a share of remaining ability, not a share of a fixed total. Rate someone 50% disabled and 50% of their capacity remains — so the next condition is applied to what's left, not to the original whole. That's what stops ratings exceeding 100%.

Worked through, with 50% and 30%:

  1. Order them highest to lowest — 50, then 30.
  2. Look up the intersection in the VA's combined ratings table: 50 in the left column, 30 along the top.
  3. Read the result — 65.
  4. Round to the nearest 10% — 65 rounds to 70%.

So 50 and 30 give you 70, not 80.

The rounding rule is standard: values ending 1 to 4 round down, values ending 5 to 9 round up.

For three or more conditions, repeat the step using the previous unrounded combined value against the next rating, and only round at the very end. Rounding as you go produces a different — wrong — answer.

Who is eligible?

Everyone with more than one service-connected condition has a combined rating, so this applies to most claimants rather than a subset.

The practical consequence is that a low additional rating may not move your combined figure at all once it's rounded. Adding 10% to an existing 70% gives 73, which rounds back to 70 — the same payment. That is not the VA declining your claim; it is the arithmetic.

The reverse also matters: near a rounding boundary, a small additional rating can push you up a whole band. At 65 combined (paid at 70%), one more condition can be the difference between 70% and 80%.

How do I apply?

  • Check the combined figure, not the individual ones: Your payment follows the combined rounded rating. Adding up your letters will overstate it.
  • Use the VA's combined ratings table: It is published on VA.gov. Do not use a law firm's calculator to decide whether to appeal.
  • Work with unrounded values for three or more conditions: Round only at the end. Rounding at each step gives the wrong answer.
  • Understand why a new rating may change nothing: At 73 combined you are paid at 70%, and so is someone at 65. That is rounding, not a denial.
  • Look at where you sit relative to a boundary: If you are at 65 or 75 combined, one more accepted condition can move you a full band.

Common questions

Why don't VA disability ratings add up?

Because each rating applies to your remaining ability rather than the original whole — the VA's whole person theory. That is what keeps combined ratings from exceeding 100%.

What do 50% and 30% combine to?

65 unrounded, which rounds to 70%. Not 80%.

How does the VA round combined ratings?

To the nearest 10%: values ending 1 to 4 round down, values ending 5 to 9 round up.

How are three or more ratings combined?

Combine the two highest, then combine that unrounded result with the next rating, and so on. Round only the final figure.

Can a new rating leave your payment unchanged?

Yes. Going from 70 to 73 combined still rounds to 70%, so the payment is the same. That is the arithmetic rather than a denial.
