VA Benefits Calculator
Estimate your monthly VA disability compensation using the official "VA Math" formula.
Dependency rates only apply to ratings of 30% or higher.
Estimated Monthly Payment
Formula: Combined Rating = 100% – (Remaining Efficiency). Each subsequent rating is applied to the remaining "healthy" percentage of the body.

What is a VA Benefits Calculator?
A VA Benefits Calculator is an essential tool for United States Veterans to estimate their monthly disability compensation. Unlike standard addition, the Department of Veterans Affairs uses a unique method often referred to as "VA Math." This system accounts for the fact that a person cannot be more than 100% disabled. Therefore, each additional disability rating is applied to the remaining "efficient" or "healthy" portion of the Veteran's body.
Who should use it? Any Veteran with one or more service-connected disabilities should use a VA Benefits Calculator to ensure they are receiving the correct compensation. Common misconceptions include the idea that a 50% rating and a 50% rating equal 100%. In reality, using the VA Benefits Calculator logic, a 50% and 50% rating actually results in an 80% combined rating.
VA Benefits Calculator Formula and Mathematical Explanation
The mathematical derivation of VA disability follows a diminishing returns model. The formula is:
Combined Rating = 100 – (100 * (1 – R1) * (1 – R2) * (1 – R3)…)
Where R is the decimal form of each disability rating. If a bilateral factor is involved (disabilities affecting both arms or both legs), an additional 10% of the combined bilateral value is added before the final rounding.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Individual Rating | Severity of a single condition | Percentage (%) | 0% – 100% |
| Efficiency | The remaining "healthy" percentage | Percentage (%) | 0% – 100% |
| Bilateral Factor | Boost for paired extremities | Multiplier | 1.1x (10% boost) |
| Combined Rating | Final rounded disability score | Percentage (%) | 10% – 100% |
Practical Examples (Real-World Use Cases)
Example 1: The Multiple Disability Scenario
A Veteran has three service-connected disabilities: PTSD (50%), Sleep Apnea (30%), and Tinnitus (10%).
- Step 1: Start with 100% efficiency. Apply 50%. Remaining: 50%.
- Step 2: Apply 30% of the remaining 50% (which is 15%). Remaining: 35%.
- Step 3: Apply 10% of the remaining 35% (which is 3.5%). Remaining: 31.5%.
- Result: 100% – 31.5% = 68.5%. This rounds to 70%.
Example 2: The Bilateral Factor
A Veteran has a 10% rating for the left knee and a 10% rating for the right knee. Using the VA Benefits Calculator bilateral logic:
- Combine the two 10% ratings: 10% + (10% of 90%) = 19%.
- Add the 10% bilateral boost: 19% + 1.9% = 20.9%.
- This 20.9% is then used as a single rating in the overall calculation.
How to Use This VA Benefits Calculator
- Select Your Ratings: Use the dropdown menus to select each of your individual disability ratings.
- Toggle Bilateral: If you have disabilities in both arms or both legs, check the "Bilateral" box next to those specific ratings.
- Choose Dependency: Select your current marital and family status, as this significantly changes the monthly payment for ratings 30% and above.
- Review Results: The VA Benefits Calculator will instantly update your combined rating and estimated monthly pay.
- Analyze the Breakdown: Look at the table below the results to see exactly how the "VA Math" was applied to your specific case.
Key Factors That Affect VA Benefits Calculator Results
- The Bilateral Factor: This is a 10% "bonus" added to the combined rating of disabilities affecting paired extremities. It can often push a Veteran into a higher rounding bracket.
- Rounding Rules: The VA always rounds the raw combined score to the nearest 10%. For example, 64% rounds down to 60%, while 65% rounds up to 70%.
- Dependency Status: Veterans with a rating of 30% or higher receive additional compensation for spouses, children, and dependent parents.
- SMC (Special Monthly Compensation): In cases of extreme disability (like loss of use of a limb), Veterans may qualify for SMC, which exceeds the standard 100% pay rate.
- COLA Adjustments: Every year, the Social Security Administration's Cost of Living Adjustment (COLA) changes the dollar amounts in the VA Benefits Calculator.
- Pyramiding: The VA does not allow "pyramiding," which is receiving two ratings for the same symptom. This is a limitation to keep in mind when inputting data.
