4 steps
- Order of severity: 50%, 30%.
- Most severe disability: 50%.
- Combine 50% with 30%: 30% of the 50% remaining efficiency is 15, so 50 + 15 = 65 -> 65%.
- Convert once to the nearest degree divisible by 10: 65% -> 70% (values ending in 5 are adjusted upward).

38 CFR 4.25 example: a 50% and a 30% disability example
With Individual disability ratings: 50,30, the calculator returns Combined value before conversion to a multiple of 10: 65, Combined disability rating: 70. This example is checked against an independent source in the test suite.
What you can compare
Change one input at a time to see how it affects Combined disability rating, Combined value before conversion to a multiple of 10 and Bilateral disabilities combined (before the factor). The inputs you can vary are Individual disability ratings and Bilateral (paired-extremity) ratings.
Understanding Combined disability rating, Combined value before conversion to a multiple of 10 and Bilateral disabilities combined (before the factor)
This reproduces the arithmetic of 38 CFR 4.25 and 4.26. It is not a rating decision: only VA can assign ratings, and special provisions (SMC, TDIU, protected evaluations, amputation rule) are not applied here.
Results are general information, not financial, tax, legal, medical or engineering advice. Check any decision that matters with a qualified professional.
