What Is the VA Disability Calculator?

This calculator applies the official U.S. Department of Veterans Affairs (VA) method for combining multiple disability ratings into a single percentage. Because VA disability ratings do not simply add up, two 50% ratings do not equal 100% — they combine to 75%. This tool uses the "whole person" approach to give you the correct combined rating used to determine compensation. It applies only to U.S. veterans and reflects the VA's standard combined ratings table method.

How to Use It

Enter each of your individual disability ratings (0–100%) in the fields provided. You can enter up to five ratings; leave unused fields blank or at zero. The calculator automatically sorts your ratings from highest to lowest, combines them, and rounds the result to the nearest 10% as the VA does.

The Formula Explained

Start with 100% of a healthy "whole person." The largest rating is applied first, leaving a remaining efficiency. Each subsequent rating is applied only to what remains. Mathematically the remaining efficiency is the product of (1 − rating) for every disability, so the combined value is:

$$C = 100 - 100\prod_{i}\left(1 - \frac{r_i}{100}\right)$$

The final value is rounded to the nearest multiple of 10.

Each rating reduces only the remaining healthy portion of the whole person.

Worked Example

Suppose you have ratings of 50%, 30%, and 20%. Process them in descending order:

• Start: 100% efficient.
• Apply 50%: \(100 \times 0.50 = 50\%\) remains (50% disabled).
• Apply 30%: \(50 \times 0.70 = 35\%\) remains (65% disabled).
• Apply 20%: \(35 \times 0.80 = 28\%\) remains → 72% disabled.

The exact value is 72%, which rounds to a 70% combined VA disability rating.

Worked example: 50% and 30% combine to about 65%, rounded to 70%.

FAQ

Why don't my ratings just add up? The VA uses a whole-person concept: once part of you is rated disabled, later ratings only apply to the healthy remainder, so totals are always lower than a simple sum.

How does rounding work? After combining, the value is rounded to the nearest 10%. Values ending in 5 or above round up (e.g., 75 → 80), below 5 round down (e.g., 72 → 70).

Does this include the bilateral factor or dependents? No. This tool computes the basic combined rating only. The bilateral factor and dependent adjustments are separate and may change your final compensation.
