What is a Combined VA Rating?
A combined VA rating is the overall disability percentage assigned by the Department of Veterans Affairs (VA) to a veteran who has multiple service-connected disabilities. This single percentage determines the monthly compensation amount a veteran receives. It's crucial to understand that the VA does not simply add percentages together. Instead, it uses a complex formula that prioritizes higher individual ratings, reflecting the cumulative impact of disabilities on a veteran's earning capacity.
Who Should Use This Calculator?
Any veteran with two or more service-connected disabilities should use this combined VA rating calculator. Whether you are filing an initial claim, considering an increase, or simply want to understand how your current ratings are calculated, this tool provides clarity. It helps you estimate your potential combined rating, which is vital for financial planning and understanding your VA benefits.
Common Misconceptions About Combined VA Ratings:
- Simple Addition: Many veterans mistakenly believe their combined rating is the sum of their individual ratings (e.g., 30% + 20% = 50%). This is incorrect. The VA formula is designed to be less than the sum of individual ratings.
- Equal Weighting: Veterans sometimes assume each rating contributes equally. The VA formula assigns greater weight to higher ratings.
- Automatic Increases: A higher combined rating doesn't always mean a significant jump in compensation if the increase is small or if it doesn't cross a compensation tier threshold.
- Reaching 100%: Achieving a 100% combined rating can be done with ratings significantly less than 100% individually, often through combinations that are highly impairing.
Combined VA Rating Formula and Mathematical Explanation
The VA uses a specific formula to calculate the combined disability rating. The core principle is to take the highest disability rating first, then calculate the remaining capacity of the veteran, and then apply the next highest rating to that remaining capacity. This process is repeated for all service-connected conditions.
The VA Rating Combination Formula:
The formula can be expressed iteratively:
Combined Rating = 100 – [(100 – R1) * (100 – R2) * (100 – R3) * … * (100 – Rn)]
Where R1, R2, R3, …, Rn are the individual disability ratings, sorted from highest to lowest.
Step-by-Step Derivation:
- Sort Ratings: Arrange all individual disability ratings in descending order (highest to lowest).
- Calculate Remaining Capacity: For each rating (R), calculate the percentage of remaining capacity: (100 – R).
- Multiply Remaining Capacities: Multiply all the "remaining capacity" percentages together.
- Calculate Final Combined Rating: Subtract the product of remaining capacities from 100. The result is the combined rating.
The VA then rounds this final combined rating to the nearest 10 percent. For example, a calculated 83% becomes 80%, and 87% becomes 90%.
Variable Explanation Table:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Rn | Individual Service-Connected Disability Rating | Percentage (%) | 0% to 100% |
| (100 – Rn) | Remaining Unimpaired Capacity after considering disability Rn | Percentage (%) | 0% to 100% |
| Product of Remaining Capacities | The cumulative unimpaired capacity across all disabilities | Percentage (%) | 0% to 100% |
| Combined Rating | The overall disability percentage calculated by the VA | Percentage (%) | 0% to 100% (then rounded to nearest 10%) |
This calculation method ensures that each additional condition has a diminishing effect on the overall combined rating, reflecting the VA's goal of compensating for the reduction in earning potential.
Practical Examples (Real-World Use Cases)
Let's walk through a couple of scenarios to illustrate how the combined VA rating calculator works:
Example 1: Moderate Disabilities
Veteran A has the following service-connected disabilities:
- Musculoskeletal condition: 40%
- Tinnitus: 10%
- Sleep Apnea: 30%
Inputs:
- Condition 1: 40%
- Condition 2: 30%
- Condition 3: 10%
Calculation Steps:
- Sorted Ratings: 40%, 30%, 10%
- Remaining Capacities: (100 – 40) = 60%, (100 – 30) = 70%, (100 – 10) = 90%
- Multiply Remaining Capacities: 0.60 * 0.70 * 0.90 = 0.378
- Calculate Combined Rating: 100 – (0.378 * 100) = 100 – 37.8 = 62.2%
Result: The calculated combined rating is 62.2%. The VA will round this to the nearest 10%, resulting in a combined VA rating of 60%.
Financial Interpretation: This veteran would receive compensation based on a 60% disability rating, which is significantly less than the simple sum (40 + 30 + 10 = 80%).
Example 2: Higher Disabilities
Veteran B has the following service-connected disabilities:
- Back injury: 70%
- PTSD: 50%
- Migraines: 20%
- Knee injury: 40%
Inputs:
- Condition 1: 70%
- Condition 2: 50%
- Condition 3: 40%
- Condition 4: 20%
Calculation Steps:
- Sorted Ratings: 70%, 50%, 40%, 20%
- Remaining Capacities: (100 – 70) = 30%, (100 – 50) = 50%, (100 – 40) = 60%, (100 – 20) = 80%
- Multiply Remaining Capacities: 0.30 * 0.50 * 0.60 * 0.80 = 0.072
- Calculate Combined Rating: 100 – (0.072 * 100) = 100 – 7.2 = 92.8%
Result: The calculated combined rating is 92.8%. The VA will round this to the nearest 10%, resulting in a combined VA rating of 90%.
Financial Interpretation: Even with substantial individual ratings, the combined rating reflects the overlap in functional impact. This veteran receives compensation at the 90% level.

Key Factors That Affect Combined VA Rating Results
Several factors influence the final combined VA rating and the veteran's overall compensation:
- Severity of Individual Disabilities: This is the most direct factor. Higher individual ratings contribute more significantly to the combined rating, even with the VA's formula. A 70% rating has a much larger impact than a 10% rating.
- Number of Service-Connected Conditions: While the VA formula accounts for multiple conditions, having more disabilities generally pushes the combined rating higher, assuming they are distinct and rated independently. However, the effect diminishes with each added condition.
- Order of Ratings (Highest to Lowest): The VA formula requires sorting ratings from highest to lowest. The highest rating has the greatest impact on reducing the "unimpaired capacity," making the starting point crucial.
- Rounding by the VA: The VA rounds the final calculated combined rating to the nearest 10%. This can sometimes be a significant difference. A calculated 87% becomes 90%, but a 82% becomes 80%. This rounding affects compensation tiers.
- Interconnectedness of Conditions: While the VA combines ratings mathematically, a veteran may claim secondary conditions related to an existing service-connected disability. The VA evaluates these separately, and their combination follows the same formula. Understanding which conditions are truly distinct versus secondary is important.
- Maximum Combined Rating: Veterans with specific combinations of disabilities, particularly those resulting in total and permanent disability, may be eligible for Special Monthly Compensation (SMC) or 100% schedular rating (TDIU – Total Disability based on Individual Unemployability) which are separate from the standard combined rating calculation.
- Inflation and Cost of Living Adjustments (COLA): While not directly affecting the *calculation* of the combined rating itself, annual COLA adjustments impact the actual monetary value of the compensation received, increasing it over time.
A thorough understanding of these factors helps veterans navigate the VA system more effectively and ensures they receive the benefits they deserve.
Frequently Asked Questions (FAQ)
How does the VA combine disability ratings?
The VA uses a specific formula: 100 – [(100 – R1) * (100 – R2) * … * (100 – Rn)], where R is each individual rating sorted highest to lowest. The result is then rounded to the nearest 10%.
Can my combined VA rating be higher than the sum of my individual ratings?
No, the VA's formula is designed so that the combined rating is always less than or equal to the sum of the individual ratings. It reflects remaining earning capacity, not total impairment.
What if I have only one service-connected disability?
If you have only one service-connected disability, your combined VA rating is simply that disability's rating. The calculator is designed for veterans with two or more conditions.
What does it mean if my calculated rating is 88%?
The VA rounds the calculated rating to the nearest 10%. So, a calculated 88% would be rounded up to 90% for compensation purposes. A calculated 82% would be rounded down to 80%.
Can I combine ratings for temporary disabilities?
Temporary disabilities, such as those from convalescence or healing periods, may be assigned temporary ratings. These are combined with other ratings using the same formula and are temporary until the condition stabilizes or is re-evaluated.
What if my conditions are related?
The VA combines all service-connected ratings. If one condition is considered secondary to another service-connected condition (e.g., tinnitus secondary to hearing loss), the secondary condition is rated independently and then combined with the primary rating using the standard formula.
Does the VA consider unemployability?
Yes, veterans who are unable to maintain substantially gainful employment due to their service-connected disabilities may be eligible for Total Disability based on Individual Unemployability (TDIU). This often results in compensation at the 100% rate, even if their schedular combined rating is lower.
How often can my combined rating be re-evaluated?
The VA may re-evaluate your disability rating if your condition improves, worsens, or if you request an increase and provide new evidence. Ratings can be static (permanent) or require periodic review.
