Navigating the U.S. Department of Veterans Affairs (VA) disability ratings can feel overwhelming. Veterans who receive multiple disability ratings often struggle to understand how those ratings combine into one overall percentage. Unlike simple math, the VA uses a special formula to calculate combined ratings.
VA Disability Percentage Calculator
What Is the VA Disability Percentage Calculator?
The VA Disability Percentage Calculator is a simple, interactive tool that allows you to enter multiple disability ratings (for example, 50%, 30%, and 20%) and instantly receive your combined VA disability rating.
This rating is crucial because it determines your monthly compensation benefits, access to healthcare, and other veteran services.
Unlike adding percentages directly (50 + 30 + 20 = 100), the VA uses a “whole person” method, which reduces the remaining “healthy” percentage with each rating. Our calculator automatically applies this formula so you don’t need to perform the complex math yourself.
Why Is This Calculator Important?
- Accuracy – Manual calculations can easily result in errors.
- Time-Saving – Instantly see your combined rating without confusing charts.
- Planning Benefits – Know your rating before filing claims or appeals.
- Transparency – Understand how the VA combines ratings.
- Confidence – Avoid surprises when you receive your official VA letter.
How to Use the VA Disability Calculator
Using the calculator is simple and requires just a few steps:
- Enter Ratings – In the input box, type your disability ratings separated by commas (e.g.,
50,30,20). - Click “Calculate” – The calculator will instantly show your combined disability percentage.
- View Results – The tool displays your final percentage clearly.
- Reset if Needed – Use the reset button to clear inputs and start again.
Example: How VA Ratings Combine
Let’s say you have three service-connected disabilities:
- 50% for PTSD
- 30% for back injury
- 20% for tinnitus
The VA doesn’t add them as 100%. Instead, the formula works like this:
- Start with the highest rating: 50% disabled → 50% disabled, 50% healthy.
- Apply the second rating to the remaining healthy portion: 30% of 50 = 15 → new disability total = 65%.
- Apply the third rating: 20% of 35 (remaining healthy) = 7 → new total = 72%.
- Rounded to the nearest 10% → 70% combined rating.
This is exactly how our tool calculates results automatically.
