Example: 50% + 30% — 65% unrounded, rounds to 70% combined rating.
Behind the numbers
How your VA combined rating is calculated
The VA never adds disability ratings together. Instead it uses the combined-ratings table method, which works on what is left of you — your “efficiency.” You start at 100% efficiency. The largest rating is applied first: it takes that percent away from 100. The next rating is then applied only to what is left, not to the full 100, and so on down the list. That is why 50% plus 30% is 65% before rounding, not 80%. After all ratings are applied, the result is rounded to the nearest 10% — that rounded number is your combined rating. This calculator follows that exact method for up to five ratings. It is a 2026 estimate for planning only and is not official VA advice; the VA’s own decision is the only official result.
Sort the ratings largest first. Start with 100% efficiency. For each rating, remaining efficiency = remaining × (1 − rating ÷ 100). Combined = 100 − remaining, then round to the nearest 10%.
Worked example, 50% + 30%: start at 100. After 50%: 100 × (1 − 0.50) = 50 left. After 30%: 50 × (1 − 0.30) = 50 × 0.70 = 35 left. Combined = 100 − 35 = 65%, which rounds to the nearest 10% = 70%.
Common results
Common combined ratings
| Your ratings | Unrounded result | Combined rating |
|---|---|---|
| 50% + 30% | 65% | 70% |
| 40% + 20% + 10% | 56.8% | 60% |
| 60% + 40% | 76% | 80% |
| 30% + 20% | 44% | 40% |
| 70% + 50% | 85% | 90% |
| 10% only | 10% | 10% |
Tips before you use your rating
Always sort ratings largest to smallest before combining — the order changes nothing in the math here, but it matches how the VA table reads and keeps your working clear.
A combined rating can never reach 100% by combining ratings below 100%; only a single 100% rating, or total disability based on individual unemployability (TDIU), gives a 100% payment level.
This calculator does not include the bilateral factor, an extra adjustment the VA adds when you have disabilities on both sides of the body — the real VA result can be slightly higher.
Your combined rating decides your monthly payment amount, but each separate rating also matters for claims and appeals, so keep the full list.
If your result looks wrong, check that you entered each rating once — entering the same condition twice is the most common mistake.
Good to know
Frequently asked questions
Why isn't my combined rating just the sum of my ratings?
Because the VA measures what is left of your efficiency, not what was taken. Each new rating applies only to the efficiency remaining after the ones before it, so every extra rating adds less than its face value. That is the whole point of the combined-ratings table.
How does the VA round the combined rating?
To the nearest 10%. A result of 65% rounds up to 70%, 64% rounds down to 60%, and 56.8% rounds to 60%. A result ending exactly in 5 always rounds up.
Is this calculator the official VA result?
No. This is a 2026 estimate using the published combined-ratings method. It does not include the bilateral factor or special monthly compensation, and only a VA decision letter is official.
Can two ratings ever add up to 100%?
No. Even 90% plus 90% combines to 99% before rounding, which rounds to 100% only at 95% or above — and in practice the VA table caps combined results below a single 100% rating. A 100% combined rating comes from a single 100% condition or from TDIU.
