How VA Disability Compensation Actually Works
Combined ratings are not simple addition. Here is how the VA math works, why dependents matter, and how to calculate your monthly compensation.
The single most common surprise for veterans is that VA disability ratings do not add up the way you would expect. A 50% and a 30% rating do not make 80%. Here is what is really happening.
Combined ratings use "VA math"
The VA combines ratings sequentially against your remaining "whole person." Start at 100% healthy. A 50% rating leaves 50%. A 30% rating then applies to that remaining 50%, taking off 15 more points — landing near 65%, which rounds to the nearest 10. The order matters, and the result is always lower than straight addition. This is why two veterans with the same list of conditions can end up at different combined ratings.
Why dependents change the payment
Once your combined rating reaches 30% or higher, the monthly compensation increases based on your dependents — a spouse, children, and dependent parents each adjust the amount. Below 30%, the rate is the same regardless of dependents.
Rounding and the final number
After combining, the VA rounds to the nearest 10% to set your official rating, then looks up the dollar amount on the current compensation tables. Small differences in individual ratings can push you across a rounding line and change your payment meaningfully.
Calculate yours in seconds
Doing this by hand is error-prone. The VA Disability Rates Calculator does the combined-rating math for you, factors in dependents, and shows your estimated monthly compensation instantly — it is the most-used app we make, for exactly this reason.
This is general information, not a benefits determination. Your official rating and payment are set by the U.S. Department of Veterans Affairs.
