VA Disability, decoded.

How ratings work, what you're owed, and how to not leave money on the table — for life.

General overview of VA disability claims. Not legal or medical advice. Consider consulting a VA-accredited claims agent or VSO.

SEC 1The system that determines your compensation — forever.

How Ratings Work

WHAT A RATING MEANS

A VA disability rating is a percentage representing how much your service-connected condition affects your ability to work. Ratings range from 0% to 100%, in increments of 10%. The higher the rating, the more the VA determines your earning capacity is impacted.

Pro TipA 0% rating still matters — it establishes service connection. If the condition worsens later, you can file for an increase without proving the service connection again.
RATING LEVELS

0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%. Each level has a specific monthly payment set by Congress. At 30% and above, you receive additional compensation for dependents (spouse, children, dependent parents).

Pro TipThe jump from 20% to 30% is about more than money — it's the threshold where dependent benefits kick in. If you're at 20%, review whether additional conditions could push you to 30%.
SERVICE CONNECTION

You must prove the condition started in service (direct), was caused by service (aggravation), or was made worse by service (presumptive or secondary). Without service connection, you get nothing — this is the foundational requirement.

Pro TipPresumptive conditions skip the burden of proof for certain diseases tied to specific service (Gulf War, Agent Orange, burn pits). Check the PACT Act — the list expanded significantly in 2022.
Watch OutIf you didn't report it in service, you're not out of luck — buddy statements and post-service medical records showing continuity of symptoms can still establish the connection.
THE C&P EXAM

The Compensation & Pension exam is the VA's medical evaluation that largely determines your rating. A VA or contract examiner assesses the severity of your conditions using specific diagnostic criteria from the VA Schedule for Rating Disabilities (VASRD).

Watch OutTreat this like the most important doctor visit of your life. Describe your worst days, not your best. If you limp some days and not others, they need to know about the days you limp. Don't be stoic — be honest.
Pro TipBring a printed list of every condition, every symptom, how it affects your daily life and work. The examiner has limited time — make it easy for them to document everything.
Watch OutThe examiner may observe you from the parking lot to the exam room. If you claim a back injury, don't carry 50 pounds of gear into the building. This isn't about faking — it's about not masking your actual limitations.
SEC 2Why 50% + 30% does not equal 80%. This costs people thousands.

VA Math — Combined Ratings

WHY 50% + 30% ≠ 80%

The VA uses "combined ratings" math — not simple addition. They calculate based on your remaining "efficient" body percentage. Each additional disability rating is applied to what's left of your healthy body, not added to your total.

Watch OutThis is the single most misunderstood part of VA disability. Veterans routinely think they're rated higher than they actually are because they add their percentages. The VA does not add.
HOW IT ACTUALLY WORKS

Start at 100% healthy. A 50% disability leaves you 50% efficient. A 30% disability of the remaining 50% = 15%. Combined = 65%, which the VA rounds to 70%. The formula: take the highest rating first, then apply each subsequent rating to the remaining percentage.

Pro TipExample with three conditions: 50%, 30%, 20%. Start: 100%. After 50% → 50% remains. After 30% of 50% = 15% → 35% remains. After 20% of 35% = 7% → 28% remains. Total disability = 72%, rounded to 70%.
THE ROUNDING RULES

Combined values are rounded to the nearest 10%. The 0.5 rule: if the combined value ends in 5 or above, it rounds up. 65% rounds to 70%. 74% rounds to 70%. 75% rounds to 80%.

Pro TipIf your combined rating is just below a rounding threshold (e.g., 74%), even a small 10% secondary condition could push you over the line to the next payment tier.
BILATERAL FACTOR

If you have conditions on both sides of your body — both knees, both shoulders, both wrists — you receive an extra ~10% bump on those conditions before they enter the combined rating calculation. The bilateral factor is 10% of the combined bilateral conditions, added to their combined total.

Pro TipThe bilateral factor is often overlooked. If you have a left knee condition and your right knee compensates and develops problems, claim the right knee as secondary. The bilateral factor alone could bump your combined rating.
WHY THIS MATTERS

The difference between 90% and 100% is hundreds of dollars per month — for the rest of your life. And 100% P&T (Permanent and Total) unlocks an entirely separate tier of benefits: Chapter 35 DEA education benefits for dependents, CHAMPVA healthcare, property tax exemptions in most states, and more.

Watch OutDon't guess your combined rating — calculate it. Use an online VA disability calculator. The difference between 80% and 90% over a 40-year lifetime is over $200,000.
SEC 3The right way to file determines how fast and how much you get.

Filing Your Claim

BDD CLAIM

Benefits Delivery at Discharge — file 180 to 90 days before your separation date. The VA begins processing while you're still in service, so your rating and payments can start as soon as the day after you separate.

Pro TipThis is the single best thing you can do. BDD claims process faster and your effective date is the day after discharge. Every month you delay after separation is money you don't get back.
Watch OutYou must still be available for C&P exams at your current duty station. If you're about to PCS or go on terminal leave, coordinate timing carefully.
STANDARD CLAIM

Filed on VA.gov after separation with supporting evidence. Processing time varies — typically 3 to 6 months, sometimes longer. Your effective date is the date VA receives the claim (or the Intent to File date, if you filed one).

Watch OutIf you file a year after separation without an Intent to File, you lose backpay to your discharge date. That could be tens of thousands of dollars gone.
FULLY DEVELOPED CLAIM (FDC)

You submit ALL evidence upfront — service treatment records, private medical records, buddy statements, nexus letters. You certify there's no more evidence to gather. In exchange, the VA processes it faster.

Pro TipFDC is the fastest standard track. If you have strong evidence ready, go this route. If you're still gathering records, file a standard claim and submit evidence as you get it.
INTENT TO FILE

A placeholder that locks in your effective date for up to one year. File this FIRST — even if your full claim isn't ready. It gives you 12 months to gather evidence while preserving your backpay date.

Pro TipFile an Intent to File the day you decide to file a claim. It takes 5 minutes on VA.gov or one phone call to 1-800-827-1000. There is zero downside and potentially tens of thousands of dollars of upside.
Watch OutThe Intent to File expires after one year. If you don't submit your actual claim within 12 months, you lose the effective date and have to start over.
WHAT YOU NEED

Service treatment records (every sick call, profile, and ER visit), buddy statements (sworn statements from fellow service members who witnessed your condition), private medical records (civilian doctor records), nexus letters (a doctor's letter linking your condition to service), and your personal statement (your detailed account of what happened and how it affects your life).

Pro TipRequest your full service treatment records before separation. After you leave, getting them from the National Personnel Records Center can take months. Do it while you still have access.
SEC 4The difference between a denied claim and a 100% rating is evidence.

Evidence That Wins Claims

SERVICE TREATMENT RECORDS

Every sick call visit, every physical therapy session, every profile, every ER visit, every line of duty determination. These are your contemporaneous proof that something happened in service.

Pro TipRequest your COMPLETE records — not just the summary. Ask for radiology reports, lab work, surgical notes, everything. Records you don't know exist could support conditions you haven't claimed yet.
Watch OutIf your STRs are incomplete or missing, it's not over. The VA has a duty to assist. Buddy statements, unit records, and even your own contemporaneous notes (journals, texts, emails) can fill gaps.
BUDDY STATEMENTS

Sworn statements from fellow service members who witnessed your condition, injury, or the circumstances that caused it. They don't need to be medical professionals — they just need to describe what they observed.

Pro TipGet buddy statements BEFORE you all scatter after ETS. Track down your squad leader, your battle buddy, anyone who saw you limping, struggling, or going to sick call. A VA Form 21-10210 (Buddy/Lay Statement) makes this easy.
Pro TipBuddy statements should be specific: dates, locations, unit, what they witnessed. "I saw SGT Smith struggle to carry his ruck during the March 2022 field exercise at Fort Bragg due to his back pain" beats "He always had a bad back."
NEXUS LETTER

A medical doctor's letter that directly connects your current condition to your military service. It states that the condition is "at least as likely as not" (50% or greater probability) related to your service. This is the golden document.

Pro TipThe magic phrase is "at least as likely as not." If your doctor writes "it is possible" or "it could be related," that's not strong enough. The nexus must meet the 50% threshold to carry legal weight.
Watch OutA good nexus letter costs money ($1,000-$3,000+ from independent medical opinion providers), but it can mean the difference between 0% and 70%. On difficult claims, it's the single most impactful investment you can make.
Pro TipA nexus letter should reference your specific service treatment records, describe the medical mechanism connecting service to your condition, and cite relevant medical literature. Generic one-paragraph letters get ignored.
PRIVATE MEDICAL RECORDS

Records from civilian doctors showing ongoing diagnosis, treatment, and symptom severity. These prove your condition didn't just disappear after service — it persists and affects your life.

Pro TipSee your doctor for EVERY condition you plan to claim — and be thorough. Describe your symptoms, their frequency, and their impact on daily life. The doctor's notes become evidence.
Watch OutIf there's a gap of years between your service and seeking civilian treatment, the VA may question continuity. Explain the gap in your personal statement — lack of insurance, military culture of pushing through pain, etc.
PERSONAL STATEMENT

Your own detailed account of what happened, when, where, which unit you were in, and — critically — how the condition affects your daily life today. Describe your worst days: can you bend down, stand for long periods, sleep through the night, concentrate at work?

Pro TipBe specific and honest. "My back hurts" is weak. "I wake up 3-4 times per night due to lumbar pain. I cannot sit for more than 30 minutes without standing. I dropped from running 5 miles a day to being unable to walk around a grocery store without pain" tells a rater exactly how this affects you.
Watch OutDon't exaggerate — but don't minimize either. The military trained you to push through pain and say "I'm fine." The VA needs to hear about the days you're NOT fine.
SEC 5The claims most veterans miss — often the easiest to prove.

Secondary Conditions

WHAT THEY ARE

Secondary conditions are disabilities caused or aggravated by a condition you're already service-connected for. You don't need to prove the secondary condition happened in service — you need to prove it was caused or made worse by a primary condition that IS service-connected.

Pro TipThis is where most veterans leave money on the table. If you have ANY service-connected condition, ask your doctor: "What other conditions could this cause or worsen over time?"
COMMON EXAMPLES

Back injury leading to radiculopathy (shooting pain down the legs). PTSD leading to sleep apnea, depression, migraines, or substance abuse disorders. Knee injury leading to hip problems from altered gait. Ankle injury leading to plantar fasciitis. Tinnitus leading to migraines or insomnia. Diabetes leading to peripheral neuropathy or erectile dysfunction.

Pro TipMental health secondaries are powerful and common. PTSD is connected to sleep apnea, migraines, IBS, GERD, bruxism (teeth grinding), hypertension, and more. Each is a separate ratable condition.
WHY THEY MATTER

You're already service-connected for the primary condition — the hardest part is done. Secondary conditions are often easier to prove because you only need a nexus between the primary and secondary condition, not between the secondary and your actual service.

Pro TipEach secondary condition gets its own rating, which enters VA math and increases your combined. Three 10% secondary conditions on top of an existing 50% rating can push you from 50% to 70% combined.
HOW TO CLAIM

File as "secondary to [your primary service-connected condition]" on VA Form 21-526EZ. Include a nexus letter from a doctor explaining the medical relationship between the primary and secondary conditions. The nexus letter should state the secondary condition is "at least as likely as not" caused by or aggravated by the primary.

Pro TipFile secondary claims at the same time as your primary if possible. If your primary is already rated, you can file secondaries at any time — there's no deadline.
Watch OutDon't assume the VA will connect the dots. Even if the relationship is medically obvious (like a knee injury causing hip problems), you need a nexus letter spelling it out explicitly.
SEC 6What the VA pays at each rating level — every month, for life.

Monthly Compensation Rates

10%

$171.23/month. No dependent add-ons at this level. Dependents only increase compensation at 30% and above.

Pro TipEven 10% gets you into the VA healthcare system (Priority Group 1-6 depending on percentage) and access to VA home loan benefits. Don't dismiss a 10% rating.
30%

$524.31/month (veteran alone). Dependents start adding here — spouse, children, and dependent parents each increase the amount. This is the first major threshold.

Pro TipAt 30%, a spouse adds roughly $60/month, and each child adds about $30/month. If you're just under 30% combined, secondary conditions could push you over this threshold and unlock dependent compensation.
50%

$1,075.16/month with spouse. Without spouse: $958.44/month. At 50%, you qualify for additional vocational rehabilitation benefits (VR&E, Chapter 31).

Pro TipVR&E at 50% or higher can pay for graduate school, certifications, tools to start a business, and even a living stipend — often better than GI Bill for certain career paths.
70%

$1,716.28/month with spouse. Without spouse: $1,556.76/month. At 70%, you may also qualify for Individual Unemployability (TDIU) if you can't work — which pays at the 100% rate.

Pro TipIf you're at 70% and unable to maintain substantially gainful employment, apply for TDIU (Total Disability Individual Unemployability). It pays the same as 100% without needing a 100% combined rating.
100%

$3,621.95/month with spouse. Without spouse: $3,456.30/month. This is full compensation, plus eligibility for dental care, CHAMPVA for dependents (if P&T), and commissary/exchange access.

Pro TipAt 100% schedular, you can still work — there's no income limit for schedular 100% (unlike TDIU). Your compensation stays the same regardless of your employment.
100% P&T

Permanent and Total — the same monthly rate as 100%, but the VA has determined your conditions are not expected to improve. This unlocks the highest tier of benefits: Chapter 35 DEA (education benefits transferable to dependents), CHAMPVA healthcare for dependents, property tax exemptions in most states, Space-A travel, and more.

Pro TipChapter 35 DEA alone is worth over $60,000 in education benefits for your dependents. If you're at 100%, check your rating decision letter for the words "permanent and total." If it's not P&T, you may be able to request it.
SMC — SPECIAL MONTHLY COMPENSATION

Additional pay beyond the 100% rate for severe disabilities: loss of use of a limb, blindness, need for aid and attendance, housebound status. SMC levels range from SMC-K ($131.44/month extra) to SMC-T (over $4,500/month extra).

Pro TipSMC-K is commonly awarded for loss of use of a creative organ (erectile dysfunction) — if you have this condition rated secondary to a medication or service-connected condition, you may qualify for the extra $131/month.
SEC 7Denied or underrated — you have options. Use the right lane.

The Appeals Process

HIGHER-LEVEL REVIEW (HLR)

Your existing evidence is reviewed again by a more senior rater. No new evidence is allowed — you're asking the VA to take a second look with fresh eyes. An informal conference (phone call) lets you explain why you think the original decision was wrong.

Pro TipBest for clear errors: the examiner didn't review your records, the rater applied the wrong diagnostic code, or the evidence clearly supports a higher rating. If the evidence is there and was just overlooked, HLR is the fastest fix.
Watch OutNo new evidence means NO new evidence — not even a buddy statement you forgot to include. If you have new evidence, go Supplemental instead.
SUPPLEMENTAL CLAIM

Submit new and relevant evidence for the VA to reconsider your claim. This includes new nexus letters, updated medical records, new diagnoses, additional buddy statements — anything that wasn't in the original claim.

Pro TipThis is the most common and versatile appeal option. Got a nexus letter since your denial? New diagnosis? Additional medical evidence? File a Supplemental. Your effective date goes back to the Intent to File or original claim date if the new evidence is tied to the original issue.
BOARD OF VETERANS APPEALS (BVA)

A formal appeal reviewed by a Veterans Law Judge. You can request a direct review (evidence only), submit new evidence, or request a hearing. BVA is the most thorough but also the longest wait — often 1-2+ years.

Watch OutBVA is the right choice for complex legal questions, multiple denied appeals, or cases that need a judge's interpretation. For straightforward rating disputes, HLR or Supplemental is faster.
LANE CHOICE

Think of it this way: HLR is fastest for clear rater errors or overlooked evidence. Supplemental is best when you have new, stronger evidence. BVA is for complex cases that need judicial review or when the other lanes have failed.

Pro TipYou can switch lanes. If HLR is denied, file a Supplemental with new evidence. If Supplemental is denied, go to BVA. You're not locked in — but each decision resets the timeline, so choose strategically.
Watch OutDon't go it alone on appeals. A VA-accredited claims agent or attorney can represent you for free on appeals (they get paid from back-pay only if you win). A good representative dramatically increases success rates.
NoteRates shown are approximate examples and change annually. Check the current year's rates at va.gov/disability/compensation-rates. Rates vary by number and type of dependents.
Red Flags

Mistakes that cost veterans thousands — monthly, for life

!
Not filing before separation

BDD claims process faster and lock in your effective date from the day after separation. Every month you wait is money you never get back. A 50% rating filed 6 months late costs you roughly $5,750 in lost backpay.

!
Saying "I'm fine" at the C&P exam

Be honest about your worst days. The examiner needs to rate your actual impairment, not your ability to push through pain. Describing only good days guarantees a lower rating than your condition warrants.

!
Not claiming secondary conditions

Secondary conditions are often easier to prove than primaries and can significantly increase your combined rating. Most veterans with a 50% rating have unclaimed secondaries that could push them to 70% or higher.

!
Using VA math wrong

People assume their percentages add up — they don't. 50% + 30% = 65% in VA math, which rounds to 70%. If you think you're at 80% but VA math puts you at 70%, you're making financial decisions based on wrong numbers.

!
Not getting a nexus letter

The nexus letter is the single most impactful piece of evidence for difficult claims. It directly connects your condition to your service. Without one, the VA rater is guessing — and they often guess against you.

!
Accepting the first rating without review

Many initial ratings are lower than warranted. Read your rating decision letter carefully — if the evidence supports a higher rating, appeal. You have one year from the decision to file without losing your effective date.

!
Not filing an Intent to File

An Intent to File locks in your effective date for up to 12 months while you gather evidence. Without it, your effective date is when the VA receives your completed claim. That delay costs real money every single month.

!
Waiting years after separation to file

You can still file — there's no deadline for VA disability claims. But you lose backpay to your separation date for every year you wait. A veteran who waits 5 years to file at 70% loses roughly $110,000 in backpay they would have received by filing at separation.

Action Plan

What to do right now — today

  1. 1

    File an Intent to File on VA.gov today to lock in your effective date. It takes 5 minutes and preserves up to 12 months of backpay.

  2. 2

    Request your complete service treatment records — every sick call, every profile, every ER visit. If you're still in, do it before you separate. If you're out, request from the National Personnel Records Center.

  3. 3

    Get buddy statements from people who served with you. Track them down now while you still can. Use VA Form 21-10210 and be specific about dates, locations, and what they witnessed.

  4. 4

    See your doctor for every condition — create a paper trail. Describe symptoms, frequency, and how they affect your daily life. Every visit becomes evidence.

  5. 5

    Contact a VSO (Veterans Service Organization) — they're free and help with claims. DAV, VFW, American Legion, and others have trained claims agents who file thousands of claims a year.

  6. 6

    File a BDD claim 180 days before separation if possible. If you've already separated, file your claim on VA.gov with all evidence you've gathered. Don't wait for "perfect" evidence — your Intent to File protects your date.
