VA Disability Ratings Explained
How the VA assigns disability percentages, how combined ratings actually get calculated, and what each rating level means for your monthly compensation.

What Is a VA Disability Rating?
Your VA disability rating is a percentage — 0% to 100%, always in 10% increments — that the VA assigns to each service-connected condition individually. It reflects how much that specific condition reduces your overall earning capacity, based on the diagnostic criteria in 38 CFR Part 4 for that particular type of condition.
A 0% rating still means the condition is officially service-connected, even though it carries no monthly payment on its own — that distinction matters because it opens the door to secondary conditions and future claims for increase if the condition worsens.
How Are Multiple Ratings Combined?
The VA uses what's often called 'whole person' math, not simple addition. Each new rating is applied to your remaining, non-disabled percentage rather than stacking directly on top of your prior ratings.
- 50% and 30% does not equal 80% — it combines to 65%, which rounds to 70%
- Start at 100% 'whole,' subtract your highest rating first, then apply each additional rating to what's left
- Bilateral conditions (affecting both arms, both legs, or paired body parts) get an additional 10% bilateral factor before combining with everything else
- The final combined number is always rounded to the nearest 10%

Calculate Your Combined RatingWhat Each Rating Level Actually Pays
Compensation increases non-linearly as your rating climbs — a 100% rating pays considerably more than double a 50% rating, not just twice as much, because the payment schedule itself is progressive rather than a flat per-percentage-point rate. Dependents (spouse, children, dependent parents) add to your monthly payment starting at the 30% rating level and above; ratings below 30% generally don't include a dependent add-on.
Because the exact dollar figures adjust annually with the cost-of-living adjustment, the most reliable way to check today's number for your specific rating and dependent situation is the VA's current compensation rate tables rather than a number that might already be a year out of date.
TDIU: The Path to 100% Pay Without a 100% Rating
If your service-connected conditions prevent you from maintaining substantially gainful employment, Total Disability based on Individual Unemployability (TDIU) pays at the full 100% rate even when your combined schedular rating is lower — generally 70% or higher with the right combination, or through extraschedular consideration in other cases. This is one of the most under-used benefits in the entire system, since many veterans assume 100% schedular is the only way to reach full compensation.
Ratings Aren't Always Permanent
A rating decision isn't necessarily the final word. If a condition worsens, you can file a claim for increase using the same evidence-based process as your original claim. If you discover a secondary condition — one caused or worsened by an already-rated condition — that's a separate, additional claim worth pursuing. And if you were denied a condition that's since become presumptive (common with PACT Act and Agent Orange expansions), re-filing is often successful where the original claim wasn't.
Conclusion
Understanding VA math turns rating decisions from a confusing black box into something you can actually plan around — whether that's deciding to pursue a secondary condition, filing for increase, or exploring TDIU.
