VA disability benefits are notoriously confusing. This hub gathers plain-language answers to the questions we hear every day — what the benefit is, how ratings and back pay work, what happens at a C&P exam, how the appeal lanes differ, and when it makes sense to hire a lawyer. For condition-specific guidance, explore pages like PTSD, TDIU, and the PACT Act. To estimate your combined rating, use our VA disability calculator.
Below are answers to the questions veterans ask us most often. If you don't see yours, reach out — we're happy to help.
What is VA disability compensation?
VA disability compensation is a monthly, tax-free benefit paid to veterans who have a current disability that is connected to their military service. It is not based on income or need — it is based on a service-connected medical condition and how severely it affects you.
How do I file a VA disability claim?
You file by submitting VA Form 21-526EZ (for an original or increased claim) online at VA.gov, by mail, or in person, along with evidence supporting a current diagnosis, an in-service event or exposure, and a link (nexus) between them. Filing an Intent to File first can protect your effective date while you gather evidence. See our overview of the different claim types for more.
How does the VA decide my disability rating?
The VA assigns a rating from 0% to 100%, in 10% increments, based on its Schedule for Rating Disabilities. The rating reflects how much your condition limits your earning capacity and daily function. Each condition has specific criteria, and the evidence in your file determines which criteria you meet.
How does VA combined ratings math work?
The VA does not simply add your percentages. It uses 'VA math,' applying each rating to your remaining non-disabled percentage. For example, a 50% and a 30% rating don't equal 80% — the 30% applies to the 50% that remains, giving roughly 65%, which rounds to a 70% combined rating. Our VA disability calculator does this math for you.
What is VA back pay and how is it calculated?
Back pay (retroactive benefits) is the money owed to you from your effective date until the VA pays your award. It is calculated using your rating percentage, dependents, and the length of time the claim was pending. Winning an old appeal can produce a substantial lump sum. Try our back pay calculator for an estimate.
What is a C&P exam and how should I prepare?
A Compensation and Pension (C&P) exam is a medical evaluation the VA orders to assess your claimed condition. Be honest and describe your symptoms on your worst days, not just when you feel your best. The examiner's report heavily influences your rating, so never minimize how the condition affects your work and daily life.
What are the VA appeal lanes under the AMA?
Under the Appeals Modernization Act, if you disagree with a decision you have three main options: a Higher-Level Review (a senior reviewer looks at the same evidence), a Supplemental Claim (you submit new and relevant evidence), or an appeal to the Board of Veterans' Appeals. Choosing the right lane is a strategic decision. Learn more on our Higher-Level Review and Supplemental Claim page.
What is the Board of Veterans' Appeals?
The Board is where a Veterans Law Judge reviews your appeal. You can choose a direct review, submit additional evidence, or request a hearing. If the Board denies your claim, you can appeal further to the Court of Appeals for Veterans Claims (CAVC).
What is TDIU (unemployability)?
Total Disability based on Individual Unemployability pays at the 100% rate even if your combined rating is less than 100%, when your service-connected conditions prevent you from maintaining substantially gainful employment. Many veterans who cannot work qualify for TDIU without realizing it. See our TDIU page for details.
What is the PACT Act?
The PACT Act, passed in 2022, dramatically expanded benefits for veterans exposed to burn pits, Agent Orange, and other toxic substances. It added many presumptive conditions, meaning the VA presumes certain illnesses are service-connected for eligible veterans. If you were previously denied a toxic-exposure claim, the PACT Act may give you a new path.
What is a presumptive condition?
A presumptive condition is one the VA automatically presumes is connected to service for veterans who meet certain exposure or service criteria — such as Agent Orange or burn pit exposure. You still must have the diagnosis, but you don't have to separately prove the causal link.
Do I really need a lawyer for my VA claim?
For an initial claim, many veterans file on their own or with a VSO. But once you've been denied, underrated, or given the wrong effective date, an accredited attorney can significantly strengthen an appeal by identifying missing evidence and making the legal arguments the VA must address. The more complex the case, the more a lawyer typically helps.
How much does a VA disability lawyer cost?
Accredited attorneys generally work on contingency, regulated by federal law. VA PTSD Firm is not a law firm and does not charge that way — our independent medical chart review, DBQ, and Nexus Letter service is a flat $1,500 fee, paid upfront, regardless of outcome. The $1,500 fee is flat and paid upfront for the chart review itself, never a percentage of back pay or future monthly benefits. You should always receive a written fee agreement before you sign.
How long does a VA claim or appeal take?
Timelines vary widely. An initial claim may take several months, a Higher-Level Review or Supplemental Claim often takes a few months to over a year, and a Board appeal can take longer depending on the docket and whether you request a hearing. Building strong evidence early is the best way to avoid repeated delays.
Can I get my effective date pushed back?
Sometimes. Your effective date is generally the date the VA received your claim, but errors, earlier informal claims, or specific legal exceptions can support an earlier date — which means more back pay. Effective date appeals are technical, so it's worth having them reviewed. See our effective date appeal page.
What if my claim was denied years ago?
A past denial is not always the end. Depending on the facts, you may be able to file a Supplemental Claim with new and relevant evidence, or the PACT Act may open a new presumptive path. A free review can tell you whether a denied claim is worth reopening.
