Understanding "VA Math"
Calculating VA disability ratings isn't as simple as adding percentages together. The VA uses a "Whole Person" concept. This means once a veteran has a disability rating, they are no longer considered 100% healthy. Any subsequent disability ratings are applied only to the "remaining" healthy portion of the individual.
The Step-by-Step Calculation Formula
To calculate the combined rating, follow these logic steps:
- Sort Ratings: List all individual ratings from highest to lowest.
- First Calculation: Start with a 100% "healthy" person. If the highest disability is 50%, subtract 50% from 100. The person is now 50% disabled and 50% healthy.
- Second Calculation: If the next rating is 20%, take 20% of the *remaining* 50% healthy portion (which is 10%). Add that 10% to the initial 50%. The person is now 60% disabled and 40% healthy.
- Rounding: The final raw number is rounded to the nearest 10%. A 64% raw score rounds down to 60%, while a 65% raw score rounds up to 70%.
Example Calculation:
Veteran has ratings of 50%, 30%, and 10%.
- Start: 100% healthy.
- 50% Disability: 100% – 50% = 50% disabled. (50% remaining healthy).
- 30% Disability: 30% of 50% remaining = 15%. Total disability: 50% + 15% = 65%. (35% remaining healthy).
- 10% Disability: 10% of 35% remaining = 3.5%. Total disability: 65% + 3.5% = 68.5%.
- Final Result: 68.5% rounds up to 70%.
Bilateral Factors
When a veteran has disabilities affecting both sides of the body (e.g., both knees, both arms), the VA applies a "Bilateral Factor." This adds an additional 10% of the combined value of those specific bilateral disabilities to the total score before combining it with non-bilateral ratings. This calculator provides a standard combined rating; however, specific bilateral conditions may result in a slightly higher final score.
