veteran disability calculator

Accurately calculate your combined VA rating using official VA math logic.

Combined VA Disability Rating

Raw Combined Score: 0.00%

Remaining "Efficiency": 100.00%

Formula Used: VA Combined Rating Method (Descending Descending Order)

What is a Veteran Disability Calculator?

A Veteran Disability Calculator is a specialized tool designed to help veterans determine their combined disability rating from the U.S. Department of Veterans Affairs (VA). Unlike standard addition, where 50% plus 50% equals 100%, the VA uses a method commonly known as "VA Math."

This calculator is essential for veterans with multiple service-connected disabilities. Who should use it? Any veteran applying for or receiving va benefits overview who has more than one rated condition. A common misconception is that ratings are simply added together; in reality, each subsequent rating is applied to the veteran's remaining "healthy" percentage.

Veteran Disability Calculator Formula and Mathematical Explanation

The mathematical logic behind the Veteran Disability Calculator follows a descending efficiency model. Here is the step-by-step derivation:

1. List all service-connected ratings in descending order (highest to lowest).
2. Start with a 100% efficiency (a fully healthy person).
3. Apply the highest disability percentage to that 100%.
4. Take the remaining percentage and apply the next highest disability percentage to it.
5. Repeat until all ratings are accounted for.
6. Round the final raw sum to the nearest 10%.

Variable	Meaning	Unit	Typical Range
Efficiency	Remaining percentage of non-disabled health	Percentage (%)	0% – 100%
Individual Rating	Assigned rating for a specific condition	Percentage (%)	0% – 100%
Bilateral Factor	Extra 10% weight for limb-pair disabilities	Percentage (%)	10% of combined limbs
Raw Score	The exact calculated disability before rounding	Percentage (%)	0% – 100%

Practical Examples (Real-World Use Cases)

Example 1: The 50/30 Rule
A veteran has a 50% rating for PTSD and a 30% rating for a knee injury. Step 1: 100% – 50% = 50% remaining. Step 2: 30% of that remaining 50% is 15%. Step 3: 50% + 15% = 65%. Step 4: The Veteran Disability Calculator rounds 65% up to a 70% combined rating.

Example 2: Multiple Minor Ratings
A veteran has four 10% ratings. 100% -> 90% (after 1st) -> 81% (after 2nd) -> 72.9% (after 3rd) -> 65.61% (after 4th). Total disability: 100% – 65.61% = 34.39%. This rounds down to 30%. Note how four 10% ratings do not equal 40%.

How to Use This Veteran Disability Calculator

Follow these simple steps to get an accurate result:

• Step 1: Locate your official VA rating decision letter.
• Step 2: Enter your highest rating in the first dropdown.
• Step 3: Enter subsequent ratings in the following boxes. The order doesn't strictly matter in this tool as the script sorts them for you, but it is good practice to follow descending order.
• Step 4: Check the "Bilateral Factor" box if you have related disabilities in both arms or both legs (this adds a complex bilateral factor guide calculation).
• Step 5: Review the "Main Result" for your final rounded percentage and "Raw Score" for the precise figure.

Key Factors That Affect Veteran Disability Calculator Results

• VA Math Logic: The non-additive nature of ratings ensures no one exceeds 100%.
• The Rounding Rule: VA rounds to the nearest 10. 4.4% rounds down, while 4.5% rounds up.
• Bilateral Factor: Disabilities affecting paired extremities (left/right arm) get a 10% boost to their combined value before being added to other ratings.
• Service Connection: Only disabilities listed as "service-connected" by the VA are included in the Veteran Disability Calculator.
• Pyramiding: VA rules prevent rating the same symptom under two different codes; this tool assumes ratings are already legally combined.
• Maximum Ratings: Certain conditions have a "cap" regardless of severity, which influences the inputs you provide.

Frequently Asked Questions (FAQ)

Can I ever reach 110%?

No. The maximum combined rating is 100%. Once you reach 100%, additional disabilities do not increase the percentage but may qualify you for Special Monthly Compensation (SMC).

What is the 2024 VA rating table?

The va rating table 2024 provides the dollar amounts associated with each 10% increment. The calculator helps you find your percentage; the table helps you find the pay.

Does a 0% rating count?

Yes. A 0% rating means the condition is service connected disabilities but not currently severe enough for compensation. It is a "placeholder" for future increases.

How does the bilateral factor work?

If you have disabilities in both legs or both arms, those are combined first, then 10% of that combination is added as a bonus before the rest of the ratings are processed.

Why is my 90% so hard to get to 100%?

When you are at 90%, you only have 10% "efficiency" left. To get to 95% (which rounds to 100%), you would need an additional 50% disability rating (50% of 10% remaining = 5%).

What if I disagree with my rating?

You can start the va appeals process if you believe the individual ratings assigned to you are too low based on your medical evidence.

Does this calculator include SMC?

No, this is for standard combined ratings. For higher-level pay, you should use an smc calculator.

Are dependents included in this calculation?

The Veteran Disability Calculator only determines the percentage. Compensation amounts including dependents are determined by separate pay tables.
