How the VA Calculates Your Disability Rating
Common sense would tell you that two ratings of 30% and 30% would equal a combined disability rating of 60%. Yet, the VA has a different way of calculating your combined. Instead of adding ratings together, they calculate percentages of percentages. Let’s use the numbers above for our example.
In the VA’s eyes, the first disability rating of 30% would mean you are 70% healthy. To rate your second disability, they would then calculate 30% of the remaining 70%. This is done by multiplying 30% by 70%.
First, let’s convert the percentages into decimals.
30% x 70% = 0.30 x 0.70
Next, we’ll multiply our two decimals to find 30% of 70%.
0.30 x 0.70 = 0.21 → 21%
In percentage form, 0.21 becomes 21%. By calculating percentages of percentages, the VA would rate your second disability at 21%, rather than the 30% they gave your first disability.
After rounding to the nearest 10%, the combined VA disability rating would then be 50%, rather than 60%. See our math below.
30% + 21% = 51% → Round to nearest 10% → 50% combined disability rating
Once your ratings reach 50%, it becomes more difficult to get higher ratings through VA math. This is especially the case the closer your ratings get to 100%.
How Your Combined Rating Affects Compensation
The higher your combined rating, the more compensation you’ll receive each month from the VA. This is why it’s important you hire one of our VA disability attorneys if your claim has been previously denied. Our VA lawyers fight hard for your rights so you can receive the veterans compensation you deserve.
Other Factors That Affect Your Rating
You may qualify for Total Disability due to Individual Unemployability (TDIU) if your service-connected condition(s) prevent you from being gainfully employed. This would give you a disability rating of 100%. You may also have a higher combined rating if your condition(s) affect both arms or legs. Yet, the VA may stop counting ratings if there are too many on one extremity.
