Va Combined Ratings Calculator
The VA Combined Ratings Calculator is an essential online tool designed for U.S. military veterans who receive multiple disability ratings from the Department of Veterans Affairs (VA). Instead of simply adding percentages together, the VA uses a special formula to determine a veteran’s overall disability rating. This combined rating directly affects monthly compensation benefits, healthcare eligibility, and other support services.
Because VA math is not straightforward, many veterans find it confusing to calculate their true combined rating manually. The VA Combined Ratings Calculator simplifies this process by automatically applying the official VA formula and showing the correct overall disability percentage in seconds.
This tool ensures accuracy, saves time, and helps veterans better understand their compensation level before submitting claims or appeals.
How the VA Combined Ratings System Works
Before using the calculator, it is important to understand how VA combined ratings are calculated.
The VA does NOT add percentages directly. Instead, it uses a “whole person theory,” which assumes a person is 100% efficient at the start.
Key Concept:
- Each disability rating reduces the remaining “healthy” portion of the body.
- The next disability is applied to what is left, not the original 100%.
Example Logic:
If a veteran has:
- 50% disability
- 30% disability
The second rating is applied to the remaining 50%, not 100%.
Formula Used in VA Combined Ratings Calculator
The standard VA formula is:
Combined Rating = A + B(100 - A)/100
Where:
- A = highest disability rating
- B = next highest rating applied sequentially
After all ratings are combined:
- The result is rounded to the nearest 10%
- Values ending in 5 or higher are rounded up
What Inputs Are Required?
To use the VA Combined Ratings Calculator, you need:
1. Individual Disability Ratings
- Example: 10%, 20%, 40%, 60%, etc.
- These are assigned by VA for each condition.
2. Number of Conditions
- You can input multiple service-connected disabilities.
3. Optional Factors
Some calculators may include:
- Bilateral factor (for both arms or both legs)
- Secondary conditions
What Outputs Users Expect
The calculator provides:
- Final combined VA disability rating (e.g., 70%, 90%)
- Step-by-step breakdown of calculations
- Remaining efficiency percentage
- Estimated compensation tier (optional in advanced tools)
How to Use the VA Combined Ratings Calculator
Using the tool is simple and fast:
Step 1: Enter Your Disability Ratings
Input each VA disability percentage you have been assigned.
Step 2: Arrange or Auto-Sort
The tool automatically sorts ratings from highest to lowest for accuracy.
Step 3: Apply Calculation
Click the calculate button to process VA math.
Step 4: View Results
You will see:
- Combined disability rating
- Rounding result
- Breakdown of each step
Practical Example
Let’s say a veteran has the following ratings:
- PTSD: 50%
- Back injury: 30%
- Tinnitus: 10%
Step-by-step calculation:
- Start with 50% → remaining efficiency = 50%
- Apply 30% of remaining 50 = 15 → total = 65%
- Apply 10% of remaining 35 = 3.5 → total = 68.5%
Final result:
- Rounded VA rating = 70%
This demonstrates why manual calculation is often confusing without a tool.
Why VA Combined Ratings Are Not Simple Addition
Many users mistakenly think:
50% + 30% + 10% = 90%
However, VA uses diminishing efficiency logic:
- Each new condition affects only the remaining healthy portion
- This prevents inflated disability totals

Important Notes About VA Ratings
- Final ratings are always rounded to the nearest 10%
- VA uses combined tables internally
- Bilateral conditions may increase final rating
- Secondary conditions are calculated separately
20 FAQs with answers:
1. What is a VA Combined Ratings Calculator?
It is a tool that calculates total VA disability ratings using official VA math.
2. Does VA add disability percentages directly?
No, VA uses a combined rating formula instead.
3. Why is VA math so complicated?
Because each disability is applied to remaining health, not total 100%.
4. Can I manually calculate my VA rating?
Yes, but it is difficult and error-prone without a calculator.
5. What is the highest VA disability rating?
100% is the maximum combined rating.
6. What is a bilateral factor?
An adjustment for disabilities affecting both arms or both legs.
7. Does order of disabilities matter?
Yes, they are sorted from highest to lowest before calculation.
8. What happens after 100% rating?
You cannot exceed 100% combined rating.
9. Do secondary conditions affect rating?
Yes, they are included in combined calculations.
10. Is VA math fair?
It is designed to reflect overall functional impairment more accurately.
11. Can I use this calculator for appeals?
Yes, it helps estimate possible outcomes.
12. Is rounding always applied?
Yes, VA rounds to nearest 10%.
13. What if I have many disabilities?
The calculator handles multiple entries easily.
14. Does PTSD count differently?
No, it is treated like other percentage ratings.
15. Can combined rating decrease?
Yes, if conditions improve or are re-evaluated.
16. Is this calculator official VA tool?
No, but it uses official VA formulas.
17. How often should I recalculate?
Whenever your disability ratings change.
18. Can I include old claims?
Only current active service-connected ratings should be used.
19. What is remaining efficiency?
It is the portion of the body still considered unaffected.
20. Is this tool free to use?
Yes, most VA calculators online are free.
Conclusion
The VA Combined Ratings Calculator is an essential tool for every veteran navigating disability compensation. Since VA math does not work like simple addition, many veterans underestimate or overestimate their actual combined rating. This tool removes confusion by applying the official VA formula automatically and producing accurate results in seconds.
