Why don't VA ratings just add together?

The VA uses a 'whole person' or 'efficiency' formula in 38 CFR 4.25. Each rating reduces only the unrated portion of the body, not the total. Two 50% ratings combine to 75%, not 100%, because the second 50% only applies to the remaining 50% of unrated body.

Does the order I enter my conditions matter?

No. The calculator always sorts ratings from highest to lowest before applying the formula, so the math is identical regardless of input order.

What if my combined rating is 95% or higher?

The VA converts a final Table I value of 95–99% to 100% for compensation purposes. That nearest-10 conversion happens only after all disabilities are combined.

Is this calculator the same as the VA's?

Yes — we apply the Table I sequence and final conversion described in 38 CFR 4.25. Results are an estimate; the official rating decision is made by a VA rater based on your full medical evidence and exam results.

Step-by-step math

Ratings are processed from highest to lowest. Each whole-number Table I value is carried into the next combination.

Step 1: 50%
Combined rating starts at 50%.
Step 2: 30%
30% × (50% remaining unrated) ÷ 100 = 15%. Table I combined value: 65%.
Final: Convert once to the nearest 10%
Compensation rating: 70%
