1. What is VA Combined Rating?

The VA Combined Rating is calculated using a special formula that accounts for the cumulative effect of multiple disabilities. It's not a simple sum of individual ratings but rather accounts for how disabilities interact.

2. How Does the Calculator Work?

The calculator uses the VA's standard combined rating formula:

\[ \text{Combined Rating} = 100\% - \left[(100\% - R_1) \times (100\% - R_2) \times \cdots \times (100\% - R_n)\right] \]

Where:

\( R_1, R_2, \ldots, R_n \) — Individual disability ratings (as percentages)

Explanation: The formula calculates the remaining ability after each disability is applied sequentially, then converts back to a disability percentage.

3. Importance of Combined Rating

Details: The combined rating determines your overall disability percentage, which affects your monthly compensation amount and eligibility for additional benefits.

4. Using the Calculator

Tips: Enter your individual disability ratings separated by commas (e.g., "30, 20, 10"). The calculator shows both the exact combined percentage and the VA-rounded percentage (to nearest 10%).

5. Frequently Asked Questions (FAQ)

Q1: Why doesn't the VA just add ratings together?
A: The VA system accounts for the fact that disabilities don't simply add up - a person with two 50% disabilities isn't 100% disabled.

Q2: How does the VA round combined ratings?
A: The VA rounds to the nearest 10%. Ratings ending in 1-4 round down, 5-9 round up.

Q3: What's the maximum combined rating?
A: The maximum is 100%, though special rules apply for certain severe disabilities.

Q4: Do all conditions get combined?
A: Only service-connected conditions are included in the combined rating calculation.

Q5: How does bilateral factor work?
A: Bilateral conditions (affecting both arms/legs) receive an extra 10% of their combined value before being added to other ratings.
