1. What is VA Combined Disability Rating?

The VA Combined Disability Rating is calculated using a specific formula that accounts for multiple disability ratings. The VA doesn't simply add percentages together but uses a combined ratings table that accounts for the cumulative effect of multiple disabilities.

2. How Does the Calculator Work?

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

\[ \text{Combined Rating} = 100 - \left( \prod_{i=1}^{n} (1 - \frac{r_i}{100}) \right) \times 100 \]

Where:

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 the amount of monthly compensation a veteran receives. It also affects eligibility for additional benefits and healthcare services.

4. Using the Calculator

Tips: Enter each disability rating as a percentage (0-100). You can add multiple ratings to calculate the combined effect. The calculator follows VA rounding rules.

5. Frequently Asked Questions (FAQ)

Q1: Why doesn't the VA simply add the percentages?
A: Disabilities are not additive because each subsequent disability affects the remaining ability, not the original whole.

Q2: How does the VA round combined ratings?
A: Ratings are rounded to the nearest 10%. For example, 44% becomes 40%, while 45% becomes 50%.

Q3: What is bilateral factor?
A: Disabilities affecting both arms, legs, or paired skeletal muscles receive an additional 10% of the combined value of these disabilities.

Q4: What's the maximum combined rating?
A: The maximum is 100%, though special monthly compensation may be available beyond this for specific severe disabilities.

Q5: How often should I update my combined rating?
A: Whenever you receive a new disability rating or if your existing conditions worsen significantly.
