Notes: This tool applies the **whole person** formula, adds a **10% bilateral bonus** to the combined bilateral subset (if any), then combines with other conditions and **rounds to the nearest 10%** as the VA does. For complex cases (multiple separate bilateral groups, special rules), consult official VA guidance.
For U.S. veterans, the VA disability rating determines monthly compensation and other benefits. However, calculating this rating isn’t always simple. When you have multiple disabilities, the VA doesn’t just add percentages together—it uses a unique “VA math” formula.
That’s where the VA Disability Calculator (VA Dis Calculator) comes in. This tool helps veterans quickly estimate their combined disability rating and understand how much monthly compensation they may be entitled to. It simplifies a complex process into an easy calculation, giving veterans clarity and confidence when reviewing their benefits.
How the VA Disability Calculator Works
The VA doesn’t add disability percentages in a straightforward way. Instead, they use a “whole person” concept. For example:
- Start with a 100% whole person.
- If you have a 40% disability, you’re considered 60% efficient.
- If you then have a 20% disability, it applies to the remaining efficiency (20% of 60 = 12).
- Your combined rating becomes 40 + 12 = 52%, rounded to the nearest 10 → 50%.
The VA Disability Calculator automates this process. Instead of manually crunching numbers, you simply enter your disability ratings, and the tool instantly calculates your combined rating.
Step-by-Step: How to Use the VA Dis Calculator
- Enter Each Disability Rating
- Input the VA ratings you’ve received for each condition (e.g., 40%, 20%, 10%).
- Click Calculate
- The calculator applies VA math to determine your combined disability rating.
- View Results
- See your final combined percentage.
- The tool also shows your monthly compensation estimate based on current VA rates.
- Adjust If Needed
- Add or remove conditions to see how your combined rating changes.
Example Calculation
Imagine a veteran with the following disabilities:
- PTSD: 40%
- Back Injury: 20%
- Hearing Loss: 10%
Step 1: Apply first rating
100 – 40 = 60% efficiency left.
Step 2: Apply second rating
20% of 60 = 12. Add to 40 → 52%.
Step 3: Apply third rating
10% of remaining 48 = 5. Add to 52 → 57%.
Step 4: Round to nearest 10
57% rounds up to 60% combined rating.
👉 This veteran would receive 60% disability compensation according to VA pay tables.
