Veterans who receive disability benefits often face one major challenge—understanding how multiple VA disability ratings combine. Unlike simple math, the Department of Veterans Affairs (VA) does not just add percentages together. Instead, they use a formula that considers the “whole person” concept, meaning each new rating applies to the remaining efficiency after other conditions are calculated.
Multiple VA Disability Calculator
What is a Multiple VA Disability Calculator?
The Multiple VA Disability Calculator is a digital tool that helps veterans quickly determine their combined VA disability rating. Instead of manually applying the VA’s complex formula, you simply enter your disability ratings, and the calculator does the math instantly.
For example, if you have a 50% disability rating for PTSD and a 30% rating for a back condition, the VA does not simply add them to make 80%. The formula reduces the "whole person" percentage each time, so the actual combined rating may be different.
Our calculator provides:
- Fast results – No manual math required.
- Accurate percentages – Uses the same formula as the VA.
- User-friendly interface – Just enter numbers and click "Calculate."
How to Use the Multiple VA Disability Calculator
Using the tool is simple and requires just a few steps:
- Enter Your Ratings
- Type your disability ratings into the box, separated by commas.
- Example:
50,30,20
- Click "Calculate"
- The calculator applies the VA’s formula automatically.
- View Your Combined Rating
- The result will be displayed instantly as a percentage.
- Reset Anytime
- Use the "Reset" button to clear the form and start fresh.
Example Calculation
Let’s walk through an example to see how it works:
- You enter 50, 30, 20 into the calculator.
- The tool sorts them from highest to lowest.
- It applies the VA’s “whole person” method:
- First rating = 50% (you are now 50% disabled, 50% efficient).
- Next rating = 30% of the remaining 50% = 15%. Total = 65%.
- Next rating = 20% of the remaining 35% = 7%. Total = 72%.
- Rounded result = 72% disability rating.
Without the calculator, you would need to do this manually, which can be confusing.

A combined disability rating is the percentage the VA assigns to reflect how multiple service-connected disabilities affect your overall health and earning ability.
