How VA Math Determines Your Combined Disability Rating
Calculating your military disability rating is not a simple matter of addition. The Department of Veterans Affairs (VA) uses a specific method known as "VA Math" to determine how multiple disabilities affect a Veteran's overall ability to work and function. Instead of adding 30% and 20% to get 50%, the VA considers the whole person's remaining efficiency.
The Combined Rating Table Logic
The core concept is that a person cannot be more than 100% disabled. Therefore, each subsequent disability is calculated as a percentage of the remaining "non-disabled" portion of the Veteran. Here is a realistic example:
- Step 1: You start as 100% healthy.
- Step 2: You have a 50% disability rating. 50% of 100 is 50. You are now 50% disabled and 50% "efficient."
- Step 3: You have a second disability rated at 20%. The VA takes 20% of your remaining 50% efficiency, which is 10%.
- Step 4: 50% + 10% = 60% combined rating.
The Rounding Rule
Once all individual ratings are combined using the method above, the final number is rounded to the nearest 10%. For example, if your raw combined score is 64%, it is rounded down to 60%. If it is 65%, it is rounded up to 70%. This rounding can have a significant impact on your monthly compensation.
Why Use This Calculator?
Our Military Disability Calculator automates this complex logic, ensuring you don't have to manually cross-reference the VA's 10-page "Combined Rating Table." This tool is particularly useful for:
- Veterans filing for new secondary conditions.
- Service members undergoing the Medical Evaluation Board (MEB) process.
- Estimating potential monthly benefits for financial planning.
