Understanding "VA Math" and Combined Ratings
Calculating your VA disability rating isn't as simple as adding percentages together. The VA uses a "Combined Rating Table" based on the idea of a "whole person." This ensures that a total rating can never exceed 100%.
How the Calculation Works
When a Veteran has multiple service-connected disabilities, the VA starts with the highest individual rating first. They then apply subsequent ratings to the "remaining efficiency" of the individual. For example:
If you have a 50% rating, you are considered 50% "efficient" or "whole."
If you have a second 30% rating, the VA takes 30% of that remaining 50% (which is 15%).
Your combined rating becomes 50% + 15% = 65%.
The Rounding Rule
The VA always rounds the combined total to the nearest 10%. Following our example above, a 65% rating rounds up to 70%. If the combined total was 64%, it would round down to 60%. This rounding happens only at the very end of the calculation after all disabilities have been combined.
Bilateral Factor
If you have disabilities affecting both arms or both legs, a "Bilateral Factor" may apply. This adds an extra 10% to the combined rating of those specific limbs before they are combined with other non-bilateral ratings. This calculator provides a baseline combined rating; complex cases involving the bilateral factor may require additional adjustments.
Why Ratings Matter
Your final combined rating determines your monthly compensation amount. Ratings are calculated in 10% increments from 10% to 100%. A 0% rating is considered "service-connected" but does not receive monthly monetary compensation, though it may qualify you for other benefits like healthcare or travel pay.
