How to Use VA Disability Calculator
The VA Disability Calculator combines multiple service-connected ratings. Add each rating from 10 to 100 and the VA Disability Calculator shows the raw combined value and the rounded result.
- Add Ratings — One per row, increments of 10.
- Adjust as Needed — Remove rows or change values.
- Read Combined Rating — Raw value plus final rounded VA rating.
- Inspect Steps — Trace how each rating reduces residual capacity.
Formula & Theory - VA Disability Calculator
The VA Disability Calculator mirrors the VA Combined Ratings Table:
Start with 100% efficiency
Sort ratings high to low: r1, r2, r3, ...
After r1: efficiency = 100 × (1 − r1/100)
After r2: efficiency = previous × (1 − r2/100)
...
Combined raw = 100 − final efficiency
Combined VA rating = round(raw, nearest 10)| Symbol | Meaning |
|---|---|
| Efficiency | Remaining whole-person capacity |
| Combined raw | Pre-rounding combined rating |
| Combined VA | Official rating after rounding |
