Combine Multiple VA Disability Ratings
The VA Combined Calculator is an essential online tool designed to help veterans determine their overall disability rating when they have multiple service-connected conditions. Instead of simply adding percentages together, the VA uses a complex formula that calculates how each disability affects the remaining “healthy capacity” of a person.
Because of this unique system, many veterans find it difficult to estimate their true combined rating. The VA Combined Calculator solves this problem by automating the entire process and giving quick, reliable results.
This tool is widely used by:
- Veterans with multiple disabilities
- Claim applicants preparing VA submissions
- Advisors and legal representatives
- Individuals tracking compensation changes
How VA Combined Calculator Works
The VA does not use simple addition like 50% + 30% + 20%. Instead, it uses a remaining efficiency method.
Basic Logic:
- Start with 100% healthy body
- Apply highest disability first
- Each next disability applies to remaining health
- Final result is rounded to nearest 10%
This makes VA combined ratings more realistic and medically aligned.
Inputs Required
To use the VA Combined Calculator, users need to enter:
1. Disability Ratings
Each service-connected condition percentage (e.g., 10%, 30%, 50%).
2. Number of Conditions
Multiple injuries or illnesses can be added.
3. Order of Severity (optional)
Some tools automatically sort highest to lowest.
Output You Receive
The calculator provides:
- Final combined VA disability percentage
- Step-by-step calculation breakdown
- Rounded VA rating (10% increments)
- Estimated impact on benefits (optional tools)
VA Combined Rating Formula (Simplified)
The VA uses a diminishing value system:
Step-by-step process:
- Start with highest disability
- Subtract from 100%
- Apply next disability to remaining value
- Continue until all conditions are applied
- Round final value to nearest 10
Example:
- 60% disability → 40% remaining
- 30% of 40 = 12
- New total = 72%
- Rounded = 70%

Practical Example
A veteran has:
- Knee injury: 40%
- PTSD: 50%
- Hearing loss: 20%
Calculation:
- Start 50% → 50% remaining efficiency
- 40% of 50 = 20 → new total 70%
- 20% of 30 = 6 → final 76%
- Rounded result = 80%
Why VA Does Not Use Simple Addition
VA uses this system because:
- A person cannot be more than 100% disabled
- Each condition affects remaining health, not total health
- Prevents mathematical inflation of disability ratings
