VA Disability Combined Rating Calculator
This calculator helps you estimate your combined VA disability rating based on multiple individual ratings. The Department of Veterans Affairs (VA) uses a specific "combined rating" system, which is not a simple addition of percentages. This system accounts for the fact that a veteran cannot be more than 100% disabled.
How the VA Combined Rating System Works
The VA's combined rating system is designed to reflect the overall impact of multiple disabilities on a veteran's earning capacity. Instead of simply adding individual ratings, the VA starts with the highest rating and then calculates the impact of subsequent ratings on the "remaining efficiency" of the veteran. For example, if a veteran has a 60% disability, they are considered 40% efficient. A second disability of 20% would then be applied to that remaining 40% efficiency, not the original 100%.
The process generally follows these steps:
- List all individual disability ratings.
- Arrange the ratings from highest to lowest.
- Start with the highest rating.
- Take the next highest rating and calculate its impact on the "remaining efficiency" (100% minus the current combined rating).
- Add this new impact to the current combined rating.
- Repeat for all subsequent ratings.
- The final combined rating is then rounded to the nearest 10% (e.g., 44% rounds down to 40%, 45% rounds up to 50%).
This calculator simplifies this process for you. Please note that this calculator does not account for special rules like the bilateral factor, which can slightly increase combined ratings for disabilities affecting both sides of the body.
Enter your individual VA disability ratings below (0-100%). You can leave fields blank if you have fewer than five ratings.

Examples of VA Combined Ratings
- Example 1: A veteran has two ratings: 50% and 30%.
- Start with 50%. Remaining efficiency: 100% – 50% = 50%.
- Apply 30% to the remaining 50%: 30% of 50% = 15%.
- Combined rating: 50% + 15% = 65%.
- Rounded to the nearest 10%: 70%.
- Example 2: A veteran has three ratings: 70%, 40%, and 20%.
- Start with 70%. Remaining efficiency: 100% – 70% = 30%.
- Apply 40% to the remaining 30%: 40% of 30% = 12%.
- Current combined: 70% + 12% = 82%. Remaining efficiency: 100% – 82% = 18%.
- Apply 20% to the remaining 18%: 20% of 18% = 3.6%.
- Combined rating: 82% + 3.6% = 85.6%.
- Rounded to the nearest 10%: 90%.
Important Considerations
While this calculator provides a good estimate, the official VA decision may vary. Factors not included in this basic calculator that can influence your final rating include:
- Bilateral Factor: If you have disabilities affecting both sides of your body (e.g., both knees, both ears), the VA may apply a 10% increase to the combined rating of those specific disabilities before combining them with others.
- Special Monthly Compensation (SMC): For very severe disabilities or combinations of disabilities, veterans may be eligible for SMC, which provides additional benefits.
- Aid and Attendance: If a veteran requires the aid and attendance of another person, or is housebound, additional compensation may be available.
- Effective Dates: The date your disability is recognized can impact the amount of back pay you receive.
Always consult with a VA representative or an accredited Veterans Service Officer (VSO) for personalized advice regarding your specific claim.
