Learn how the VA calculates disability ratings and what you can do to ensure you receive the rating you deserve.
If you are a veteran dealing with a service-connected disability, understanding how the VA calculates your disability rating is one of the most important steps in securing the benefits you have earned. Disability ratings determine your monthly compensation, eligibility for healthcare, and access to additional programs. This guide walks you through the process, explains how ratings are combined, and offers practical advice on strengthening your claim.
Under federal law, veterans who suffer from injuries or illnesses that are connected to their military service are entitled to disability compensation from the VA. The amount of compensation you receive is based on your disability rating, which is expressed as a percentage from 0% to 100%.
A higher rating means more compensation. However, the VA does not simply add ratings together when you have multiple conditions. Instead, they use a formula called combined ratings, where each additional condition is applied to the remaining percentage of your overall health.

When preparing your disability claim, there are several factors that can significantly impact your rating. Medical evidence is the foundation of every successful claim. The VA relies heavily on your service records, private medical records, and the results of any Compensation and Pension examinations.
Be thorough in documenting how each condition affects your daily life. The VA rates conditions based on functional impairment, not just diagnosis. Two veterans with the same condition may receive very different ratings depending on the severity of their symptoms.
IMPORTANT NOTE
Important information highlighted for the reader — could be a statute of limitations warning, key deadline, or critical fact that veterans should be aware of before proceeding.
If you believe your current disability rating does not accurately reflect your condition, you have options. First, gather updated medical evidence that documents how your condition has worsened since your last evaluation.
You can file a supplemental claim with new and relevant evidence, request a higher-level review by a senior claims adjudicator, or appeal to the Board of Veterans' Appeals. Each path has different timelines and requirements, so consider consulting with a veterans' law attorney to determine which option gives you the best chance of a favorable outcome.
