VA Disability Ratings: How They Work

Rating System Overview

The VA assigns disability ratings in increments of 10%, ranging from 0% to 100%. Your rating reflects the severity of your service-connected conditions and directly determines your monthly compensation amount. A higher rating means higher monthly tax-free payments.

Key facts about VA disability ratings:

• Ratings are assigned per condition based on the VA Schedule for Rating Disabilities (VASRD), found in 38 CFR Part 4.
• A 0% rating means the VA acknowledges your condition is service-connected but considers it not currently disabling enough for compensation. However, a 0% rating still provides access to VA healthcare.
• A 100% rating represents total disability and provides the maximum monthly compensation.
• Permanent and Total (P&T) means the VA has determined your disability is both 100% and unlikely to improve. P&T unlocks additional benefits including Chapter 35 education benefits for dependents.

VA Math: How Combined Ratings Work

One of the most misunderstood aspects of VA disability is how multiple ratings are combined. The VA does not simply add your ratings together. Instead, they use a formula based on your remaining “whole person” percentage.

The formula works like this:

1. Start with your highest-rated condition
2. Apply the next highest rating to the remaining “whole” percentage
3. Repeat for each additional condition
4. Round to the nearest 10%

Example: A veteran has three conditions rated 50%, 30%, and 20%.

• 50% disabled means 50% “whole” remains
• 30% of remaining 50% = 15% → Total so far: 65%
• 20% of remaining 35% = 7% → Total: 72%
• Rounded to nearest 10% = 70% combined rating

This is why veterans with multiple 10% and 20% conditions often have a lower combined rating than expected. Understanding VA math is crucial for planning which conditions to claim. If you’re close to a rounding threshold (e.g., 74.5% rounds to 70%, but 75% rounds to 80%), identifying and claiming additional secondary conditions can make a significant financial difference.

Current Compensation Rates (2026)

VA disability compensation is tax-free and paid monthly. Rates are adjusted annually for cost of living (COLA). The following are approximate base rates for a veteran with no dependents:

Rates shown are approximate base rates for a single veteran with no dependents. Veterans with dependents (spouse, children, dependent parents) receive additional compensation at the 30% level and above. Check VA.gov for exact current rates.

The Rating Schedule (VASRD)

The VA Schedule for Rating Disabilities (VASRD, 38 CFR Part 4) is the official guide used by VA raters to assign disability percentages. It covers virtually every medical condition organized by body system. Each condition has specific diagnostic codes with criteria for each rating level.

Understanding the diagnostic code criteria for your specific condition is crucial for your C&P exam and claim preparation. You should know exactly what symptoms and functional limitations correspond to each rating level for your conditions.

The Bilateral Factor

The bilateral factor (38 CFR § 4.26) is an additional benefit applied when you have service-connected disabilities affecting both arms, both legs, or paired skeletal muscles. The VA adds 10% of the combined bilateral rating before combining it with your other ratings.

For example, if you have 20% for a left knee condition and 10% for a right knee condition, the bilateral combined is 28%. The bilateral factor adds 2.8% (10% of 28%), making the bilateral group contribution 30.8% before combining with other conditions.

How to Maximize Your Rating

• Claim every condition. Don’t leave conditions unclaimed. Even a 0% rating establishes service connection and can be increased later if the condition worsens.
• Understand secondary conditions. Conditions caused by your service-connected disabilities are also ratable.
• Know the rating criteria. Review the VASRD diagnostic code for each of your conditions and understand what criteria must be met for each rating level.
• Get strong nexus letters. A well-written nexus letter from a qualified medical provider is often the single most impactful piece of evidence.
• Request your C-file. Your complete claims file (C-file) contains every document the VA has about you. Reviewing it can reveal opportunities for additional claims.
• Consider TDIU. If you can’t maintain substantially gainful employment due to your service-connected conditions, you may qualify for Total Disability based on Individual Unemployability, which pays at the 100% rate.
