Disability Rating Calculator
Enter up to 5 individual disability ratings (%)
The Disability Rating Calculator is a simple yet powerful tool that helps individuals determine their combined disability percentage. Whether you’re a veteran managing multiple service-connected disabilities, an employee calculating workers’ compensation, or someone trying to understand your insurance rating, this calculator gives you an accurate and instant result.
Instead of doing complex math manually, this tool applies the official combined ratings formula (used by the VA and other disability systems) to calculate your overall disability percentage quickly and precisely.
💡 What Is a Disability Rating Calculator?
A Disability Rating Calculator combines multiple disability percentages to find your total disability rating. It uses the logic that no person can be more than 100% disabled.
For example, if you have disabilities rated at 50% and 30%, your total disability is not 80% — it’s 65%, because the second percentage applies only to the remaining “healthy” portion of your body.
This calculator uses the same combined rating math applied by the Department of Veterans Affairs (VA) and many insurance agencies to calculate fair compensation or benefits.
⚙️ How the Combined Disability Formula Works
When you have more than one disability, each one reduces your “healthy” capacity. The combined formula works step-by-step like this:
- Start with the highest disability rating.
- Subtract that percentage from 100 to find how much of your body is still “efficient.”
- Multiply your next disability percentage by the remaining efficient percentage.
- Add that result to your total disability so far.
- Continue this process for all ratings.
- Round your final result to the nearest 10% (as done by the VA).
Example Calculation:
If you have disability ratings of 50%, 30%, and 10%:
- Start with 50% → Remaining = 100 − 50 = 50
- Apply 30% of remaining: 0.3 × 50 = 15 → Total = 65%
- Apply 10% of remaining: 0.1 × 35 = 3.5 → Total = 68.5 → Rounded to 70%
✅ Final Combined Disability Rating: 70%
🧮 Example: Veteran Disability Rating
Let’s say a veteran has the following conditions:
- PTSD: 40%
- Back injury: 30%
- Hearing loss: 20%
Step 1: Start with 40% → Remaining 60%
Step 2: 30% of 60 = 18 → Total = 58%
Step 3: 20% of remaining 42 = 8.4 → Total = 66.4% → Rounded to 70%
✅ The combined disability rating is 70%, not 90%.

📘 Understanding Disability Ratings
A disability rating represents the degree of loss in earning capacity or physical ability. Ratings range from 0% to 100%, depending on the severity of your conditions.
When you have multiple disabilities, the ratings combine instead of adding directly. The calculator follows the VA Combined Ratings Table logic to determine your total impairment.
