Why VA Disability Ratings Don't Add Up
VA combines disability ratings using the remaining percentage after each rating is considered. It does not add the assigned percentages. Two ratings of 50% and 30% combine to 65, which rounds to a 70% combined rating.
Start With The Individual Evaluations
A decision may show several condition-specific evaluations and one combined evaluation. Those numbers serve different purposes. The individual evaluations describe how VA rated the separate disabilities; the combined evaluation is calculated using the rule in 38 CFR 4.25.
Before checking the arithmetic, collect the individual percentages that apply during the same period. Do not mix a past evaluation with its replacement, or include a condition whose evaluation was not yet effective. The calculator needs the assigned evaluations, not a list of possible symptoms or diagnoses.
Follow The Remaining Percentage
Imagine a starting value of 100 for the arithmetic. A 50% evaluation leaves 50. The next 30% is applied to that remaining 50, producing another 15. Adding 15 to the first 50 produces a combined value of 65, not 80.
This remaining-percentage approach explains why the same additional evaluation has a smaller numerical effect when earlier evaluations are higher. It is a calculation convention. It does not mean VA believes a person experiences only a particular fraction of pain or daily difficulty.

Keep Combining Before The Final Round
VA's table gives whole-number results at each combination. With more than two evaluations, use the whole combined result for the next step. Only after all evaluations have been combined do you convert the result to the nearest multiple of 10; a final value ending in 5 rounds upward.
For an illustrative set of 50%, 30%, and 10%, the first two combine to 65. Combining 65 with 10 gives 68.5, entered as 69 in the table. The final combined rating is 70%. Rounding 65 to 70 before adding the last evaluation uses the wrong intermediate number.

Check The Math Without Guessing An Award
Use the combined-rating calculator to display each step, then compare the input list with your decision. If the results differ, first check for missing evaluations, different effective periods, or a paired-extremity calculation. A mismatch identifies a question to investigate; it does not establish that the decision is legally wrong.
The table cannot determine whether separate evaluations are permitted, which condition is connected to service, or what percentage the evidence supports. Keep those questions separate from arithmetic. The existing combined-ratings guide explains the wider decision context, and accredited assistance can help review a disputed decision.

Frequently Asked Questions
Does 50% plus 30% mean 80%?
No. Under the ordinary combined table, the whole combined value is 65 and the final rounded rating is 70%.
Should I enter my combined rating as another condition?
No. Enter the separate evaluations once each. Adding the combined rating as an extra input counts those disabilities again.
