VA Combined Disability Rating Calculator

Enter your individual VA disability ratings below to calculate your combined VA rating according to VA Math rules. You can enter up to 7 ratings.

function calculateVARating() { var ratings = []; for (var i = 1; i = 0 && ratingValue <= 100) { ratings.push(ratingValue); } } if (ratings.length === 0) { document.getElementById("result").innerHTML = "Please enter at least one valid disability rating (0-100%)."; return; } // Sort ratings in descending order for VA Math ratings.sort(function(a, b) { return b – a; }); var combinedEfficiency = 100; // Start with 100% efficiency for (var j = 0; j < ratings.length; j++) { var currentRating = ratings[j]; // Calculate remaining efficiency after applying current disability combinedEfficiency = combinedEfficiency * (1 – (currentRating / 100)); } var unroundedCombinedRating = 100 – combinedEfficiency; // Round to the nearest 10 for the final VA combined rating var roundedCombinedRating = Math.round(unroundedCombinedRating / 10) * 10; var resultHtml = "

Your Combined VA Rating:

Understanding Your VA Combined Disability Rating

The Department of Veterans Affairs (VA) provides disability compensation to veterans who have service-connected conditions. When a veteran has multiple service-connected disabilities, the VA uses a specific method, often referred to as "VA Math," to combine these individual ratings into a single, overall combined disability rating. This combined rating determines the level of compensation and benefits a veteran receives.

How VA Math Works (It's Not Simple Addition)

Unlike simple addition, where a 50% rating and a 30% rating would equal 80%, VA Math works on the principle of "efficiency." It assumes that a veteran is 100% efficient (not disabled) before any disability is applied. Each subsequent disability rating is then applied to the *remaining* efficiency of the veteran, not to the original 100%.

Here's a simplified breakdown of the process:

1. Order Matters: The VA first lists all individual disability ratings in descending order (highest to lowest).
2. Start with 100% Efficiency: Imagine the veteran is 100% "efficient" or "whole."
3. Apply the Highest Rating: The highest disability rating is applied to this 100%. For example, a 50% rating means the veteran is 50% disabled, leaving 50% efficiency.
4. Apply Subsequent Ratings to Remaining Efficiency: The next highest rating is then applied to the *remaining* efficiency. If 50% efficiency remains, and the next rating is 30%, then 30% of that remaining 50% is lost (0.30 * 50% = 15%). The new remaining efficiency would be 50% – 15% = 35%.
5. Repeat and Round: This process continues for all disabilities. Once all ratings are combined, the resulting percentage is subtracted from 100% to get the combined disability rating. Finally, this number is rounded to the nearest 10% (e.g., 65% rounds to 70%, 64% rounds to 60%).

Example of VA Math:

Let's say a veteran has three service-connected disabilities with ratings of 60%, 40%, and 20%.

• Initial Efficiency: 100%
• 1. Apply 60% Rating: 100% – (100% * 0.60) = 40% remaining efficiency.
• 2. Apply 40% Rating: 40% – (40% * 0.40) = 40% – 16% = 24% remaining efficiency.
• 3. Apply 20% Rating: 24% – (24% * 0.20) = 24% – 4.8% = 19.2% remaining efficiency.
• Unrounded Combined Rating: 100% – 19.2% = 80.8%
• Rounded Combined Rating: 80.8% rounds to 80%.

As you can see, simply adding 60% + 40% + 20% would give 120%, which is not how the VA calculates it. The combined rating of 80% reflects the cumulative impact on the veteran's overall efficiency.

Why Use This Calculator?

This calculator helps you quickly estimate your combined VA disability rating based on the individual ratings you enter. It applies the correct VA Math rules, saving you the complexity of manual calculation. While this tool provides a reliable estimate, it's important to remember that it is not an official VA determination. The VA's final decision will be based on their comprehensive review of your medical evidence and applicable regulations.

Use this calculator as a helpful guide to understand your potential combined rating and to prepare for discussions with VA representatives or accredited claims agents.
