Va Percentage Calculator
VA Percentage Calculator
Veterans often face multiple service-connected disabilities, and determining the combined VA disability rating can be confusing. That’s where the VA Percentage Calculator comes in — a simple, reliable, and fast tool that helps veterans calculate their combined VA disability percentage based on individual ratings.
Instead of manually doing the math (which isn’t a straightforward addition), this calculator automatically applies the VA Combined Ratings Table formula to give you an accurate total disability percentage.
Whether you’re preparing for a claim, verifying a decision, or just estimating your benefits, this tool makes the process effortless and accurate.
What Is a VA Percentage Calculator?
A VA Percentage Calculator is an online tool that helps U.S. veterans calculate their combined disability rating from multiple individual ratings assigned by the Department of Veterans Affairs (VA).
The VA doesn’t simply add percentages together. Instead, it uses a unique formula based on the concept that each disability reduces the efficiency of a healthy person. The calculator automates this process, so you can easily determine your overall VA disability rating without manual calculations or confusion.
For example:
- If you have a 50% disability and another 30%, the combined rating is 65%, not 80%.
This calculator applies that same formula accurately in seconds.
How to Use the VA Percentage Calculator
Using the VA Percentage Calculator is easy and only takes a few seconds. Follow these simple steps:
Step 1: Enter Your Disability Ratings
- Input your primary disability rating in the first box (e.g., 50%).
- Enter your secondary rating in the second box (e.g., 30%).
- If you have a third disability, you can optionally enter it in the third box.
Step 2: Choose Rounding Option
Select whether you want:
- Round to Nearest 10%: For official VA ratings (e.g., 64% rounds to 60%).
- Show Exact Percentage: To see the precise mathematical result (e.g., 64.25%).
Step 3: Click “Calculate”
Press the Calculate button.
The tool instantly computes your combined VA disability percentage using the official formula.
Step 4: View and Copy the Result
Your combined percentage will appear in the result box. You can easily copy it using the “Copy” button to save for your records or share with your VA representative.
Step 5: Reset (If Needed)
Click the Reset button to clear all fields and start a new calculation.
Example Calculation
Let’s walk through a real example.
Example:
- Primary Rating: 60%
- Secondary Rating: 20%
- Additional Rating: 10%
Calculation Steps:
- Start with 60% disability — you’re 40% efficient.
- Apply the next 20% to the remaining 40% → 20% of 40% = 8%.
- Add 8% to 60% = 68%.
- Now apply 10% to the remaining 32% → 10% of 32% = 3.2%.
- Add 3.2% → 71.2%.
- Round to the nearest 10% → 70% combined disability rating.
With this calculator, you don’t have to worry about doing any of this math manually — it handles everything for you in one click.

- You can use the “exact” option to understand the real mathematical value before rounding.
- Keep in mind that additional factors like dependents or special monthly compensation (SMC) are not calculated by this tool.
Understanding How the VA Combines Ratings
The VA Combined Ratings Table uses a specific formula:
Combined Rating = 100 − [(100 − A) × (100 − B) × (100 − C) …] / 100
This means that each additional disability is applied to your remaining efficiency, not to a full 100%. That’s why combined ratings are always less than a simple total.
For example:
- 50% + 50% ≠ 100%.
- It’s actually 75% combined.
This formula ensures that your total disability percentage reflects your overall remaining health — the more disabilities you have, the smaller each new percentage affects your total.
