One question. One deep dive. Every week.

Quick Answer

You are generally eligible for VA disability compensation if three things are true: (1) you served in the active military, naval, or air service and were discharged under conditions other than dishonorable; (2) you have a current diagnosed condition; and (3) you can show a connection between that condition and your service — either it started in service, it was made worse by service, or it appeared after service because of something that happened in service. That third piece is what the VA calls a "service-connected" disability.

Below, we take each requirement apart in plain language — no jargon, no regulation numbers — the same way we walk through it on the Stand Easy Network podcast.

Requirement 1: Qualifying Service

The VA looks at two things here: your character of discharge and your length of service.

Most veterans know the first one by its shorthand — "other than dishonorable." Most discharges qualify: honorable, general (under honorable conditions), and several others. A dishonorable discharge generally bars compensation, but this area has exceptions and gray zones, and a bad-paper discharge is not always the end of the conversation. Discharge upgrades and character-of-discharge determinations are real processes.

Length of service matters too. For veterans who enlisted after September 7, 1980, the general rule is a minimum service period — typically 24 months of continuous active duty, or the full period you were called to or ordered to, if that was shorter. There are exceptions for hardship, disability incurred in service, and other categories.

Requirement 2: A Current Diagnosed Condition

This one is more straightforward than people expect, and it is where a lot of veterans stall. The VA does not pay for symptoms alone. It pays for diagnosed conditions — a medical finding on the record.

Chronic pain that no doctor has ever documented is a hard claim to win. The same pain with a diagnosis attached — even a small one — is a real starting point. If you have symptoms but no diagnosis, the first step is medical documentation, not paperwork.

Requirement 3: The Service Connection

This is the requirement that trips up the most claims, because it has several doors:

• Direct service connection. The condition started in service. You hurt your knee in training in 2012, your records show it, and your knee still hurts today.
• Presumptive service connection. The VA assumes a condition was caused by service based on where and when you served — burn pit exposures, Agent Orange, certain radiation-exposure periods, and post-service conditions appearing within a set window are the big categories.
• Secondary service connection. A condition your service-connected condition caused or made worse. Knee pain that alters your gait for years and ends in back problems is the classic example.
• Aggravation. you had a condition before service, and service made it permanently worse.

Do You Need Treatment Records From Active Duty?

Not always — and this is worth saying clearly, because many veterans assume a claim is hopeless without them. Service treatment records help enormously, but they are not the only evidence lane. Buddy statements, post-service records that document continuity, and the VA's duty to assist (which we cover in a later post in this series) all carry weight. The VA is also required to help you obtain records under its Duty to Assist obligation.

What "Eligible" Does Not Mean

Eligibility opens the door. It does not decide what happens inside the room. A rating — the percentage that determines monthly compensation — depends on the severity of the condition as the VA measures it. Two veterans with identical eligibility can end up with very different ratings because their evidence is different. That is why the claims file, not the application alone, decides the outcome. We walk through that file in our podcast episode "The File That Decides Your VA Claim."

Where to Start

If those three requirements sound like they describe you, the fastest start is a free claims-file review process — our Free VA Claims Quick-Start Guide walks through it step by step, at standeasynetwork.com. If you want an accredited representative in your corner, veterans service officers (VSOs) help free of charge, and accreditation verification is public through the VA's official search tool. Never pay anyone to file an initial claim for you.

Quick Answer

A C&P exam — Compensation and Pension exam, sometimes called a VA claim exam — is a medical appointment the VA schedules to evaluate the condition you claimed. It is not treatment. The examiner does not manage your care; they document how your condition looks today, on the record, using VA measurement standards. To prepare: know what condition(s) you claimed, describe your worst and typical days honestly rather than performing either way, bring or reference supporting evidence, and show up. Your rating decision will lean heavily on what happens in that room.

What the Exam Actually Is

The VA can only rate what it can see. Your claims file tells the story of your condition on paper; the C&P exam is where the VA checks that story against a live person.

The examiner — a VA clinician or a VA-contracted provider — works through a VA worksheet (called a DBQ, or Disability Benefits Questionnaire) specific to your claimed condition. They record range of motion, functional limits, observed symptoms, and consistency with your file. For mental health claims, the exam is a clinical interview rather than a physical measurement.

What the Examiner Is Really Writing Down

Examiners are trained to look at a few things beyond the diagnosis itself:

• What you can still do — the functional picture, not just the diagnosis.
• Consistency — whether what they see matches your file, your claims, and your behavior during the visit.
• Severity markers — things like flares, frequency of symptoms, and how the condition interferes with work and daily life.

That third one matters more than most veterans realize. A condition that is "fine" most of the time but flares badly enough to disrupt work is a different rating picture than a steady mild ache — but only if the flare pattern gets documented.

Your Only Job in That Room

Honesty. Not performance.

Two failure modes show up constantly:

• Playing it down. The veteran who spent years being told to push through walks in, says "I'm fine," and shakes off the pain out of habit. The examiner writes down what they see and hear. If you minimize, the record minimizes.
• Playing it up. The opposite veteran performs their worst day as if it were every day. Examiners read thousands of these exams, and inconsistency with the file is visible to them.

The correct answer is always the truthful, specific one: what a typical day looks like, what a bad day looks like, how often the bad days come, and what you can no longer do because of the condition.

How to Prepare — The Practical List

1. Read your claims file before the exam. Know exactly what you claimed and what the VA has asked the examiner to evaluate. Our podcast episode on the claims file walks through how to request it.
2. Know your condition's timeline. When it started, how it has changed, what treatment you have tried.
3. Track your current reality for a couple of weeks if you can. Flares, missed work, sleep, what you stopped doing. Bring notes — notes are allowed.
4. Bring evidence if you have new documentation the VA may not have (recent treatment records, a doctor's statement, medication list).
5. Plan the day. Exams are often short notice and short duration. Confirm the location, arrive early, and bring your ID.
6. Answer the questions asked, truthfully and specifically. Do not editorialize about the VA in general — stay on your condition.

What If the Examiner Is Bad?

It happens — rushed exams, dismissive examiners, exams shorter than the paperwork could allow. You have options: noting it in your file, getting your own provider to complete a DBQ as counter-evidence, and raising it in an appeal if the decision comes back wrong. We cover bad-examiner situations in a later post in this series, and our episode on exams covers what to do after.

After the Exam

The examiner's report goes into your file, and a VA rater — a different person, at a different desk — reads the whole file and writes the decision. The exam is the evidence; the rating decision is the verdict. When the decision letter arrives, read it fully, including the reasoning — it tells you exactly what the VA believed and what evidence would change their mind.

Quick Answer

TDIU — Total Disability based on Individual Unemployability, also called individual unemployability — is a VA path that pays disability compensation at the 100% rate when your service-connected conditions make it impossible to maintain "substantially gainful employment," even if your combined rating math is below 100%. There are two basic eligibility doors: one service-connected condition rated at 60% or higher, or a combined rating of 70% or higher with at least one condition rated at 40% or higher — plus, in both cases, the employment reality the conditions have created. The claim runs on VA Form 21-8940 plus your evidence file.

The Part Most People Get Wrong

Most veterans assume the math has to reach 100% before the top rate is on the table. It does not.

TDIU is not a separate disability and not a new claim for a new condition. It is a recognition built into the system: some veterans are disabled enough — by the conditions the service caused — that steady full-time work is off the table, and the percentage math alone does not capture that. The rating schedule measures conditions. TDIU measures the whole person in the working world.

The Two Doors

Door one: one service-connected condition rated at 60% or higher, where that condition by itself keeps you from holding substantially gainful employment.

Door two: a combined rating of 70% or higher, with at least one individual condition rated at 40% or higher, where the conditions together keep you from holding substantially gainful employment.

Notice what is not required: you do not need to be 100% on paper, you do not need every condition rated, and you do not need a doctor to write the words "totally disabled." The doors are about the rating structure you already have plus the employment reality the conditions created.

Beyond the doors, the VA also looks at the whole picture — age, education, work history, and whether the impairments actually prevent securing or following a substantially gainful occupation. And there is a special case worth knowing: a condition severe enough to require frequent hospitalization, or that otherwise clearly prevents gainful work, can be considered outside the normal rating floors.

What "Substantially Gainful Employment" Means

Substantially gainful employment generally means steady work that pays above the marginal line — a real job, with real wages, on a real schedule.

Two carve-outs matter:

• Marginal employment — odd jobs, occasional work, seasonal gigs, work that stays under the poverty line — does not by itself disqualify a claim.
• Sheltered employment — a protected environment where an employer, family member, or supervisor shields you from demands everyone else meets — does not count as gainful employment either.

The VA's honest question is one question: can you hold that kind of job, or can't you?

The Traps

1. Assuming you cannot file because you still pick up occasional work. Occasional is not a career. Read the carve-outs again.
2. Assuming the math must reach 100 first. That is the entire point of this path.
3. Performing. Describing your worst day as if it were every day. Examiners and raters read thousands of files; the claims that hold up are the honest ones. Describe the real pattern — hard weeks, better weeks, the trend line.
4. Quitting a job to make the application look better. Do not. A sudden voluntary break in employment can read against you. File from where you actually are.
5. Shame. A lot of us were raised on the idea that not working means failing. TDIU is not quitting — it is a benefit the system built because it knows what your service cost.

How the Claim Works

The core form is VA Form 21-8940. It asks for employment history, your conditions, and how they affect work. Past-employer information runs through VA Form 21-4192. Give yourself time on those — employers move and businesses close, and a missing form has stalled many an otherwise strong claim.

But the form is not the claim. The evidence is the claim. The VA asks one question: do the service-connected conditions documented in this file actually prevent this person from maintaining substantially gainful employment? Your medical records have to connect the dots, and your own statement — a typical day, what you can still do, what you cannot — matters more than most people realize. Consistency is the currency: the file, the forms, the exam, and your words all get read side by side.

One more thing, stated plainly: if you are granted TDIU and you return to substantially gainful work, the VA can re-evaluate the benefit. That is not a threat; it is the design. The benefit tracks reality, so keep your record matching your life.

Quick Answer

The VA does not add disability percentages together. It combines them as fractions of what's left. Each condition is rated as a percentage of impairment, then applied to the remaining "healthy" portion of the veteran — 30% for the knee first, then 20% of what remains. That's why 30% + 20% comes back as 40%, not 50%. The final combined number is rounded to the nearest 10%, and conditions affecting both arms or both legs get an extra step (the bilateral factor) that usually works in the veteran's favor.

Why the Letter Never Matches the Math in Your Head

Almost every veteran knows exactly where their decision letter is, and almost every veteran misreads what the number means. You did the math the way school taught you: thirty for the knee, twenty for the back. That should be fifty. The letter says forty.

The first thought is never math. The first thought is "they got me." But it's not a trick — it's a different arithmetic, and once you see it, you can check the VA's own work.

The Actual Method: Percentages of What's Left

The VA treats each condition as a fraction of the whole person. The first condition takes its percentage of the whole. The second condition takes its percentage of what's left. Each subsequent rating applies to a smaller remainder.

Here's the standard example:

• Knee at 30%: you're now considered 30% impaired, 70% remaining.
• Back at 20%: 20% of the remaining 70% is 14%. Total impairment: 30 + 14 = 44%, 56% remaining.

44% rounds to the nearest 10% — and that's how a pair of ratings that "adds" to 50 comes back from the VA as a 40% combined rating. The ten-point gap between the letter and your arithmetic is the combined ratings table doing exactly what it's built to do.

The VA does this with a published table (the combined ratings table) rather than step-by-step subtraction, but the logic is exactly this. Every combination of ratings maps to a final combined number, and the table always rounds to the nearest 10% — a combined 34% becomes 30%, a combined 35% becomes 40%.

The Bilateral Factor

One more step can change the answer, and it usually helps: the bilateral factor.

If you have rated conditions affecting both arms, both legs, or paired bones (knees, ankles, wrists), the VA first combines those paired ratings together, then adds an extra 10% of that combination to account for the added disability of having both sides impaired. That adjusted figure then enters the main combined-ratings math.

It's one of the most commonly missed pieces of the math — and one of the reasons an independent check of the letter sometimes finds the VA itself under-calculated.

What a Rating Actually Measures

Worth saying plainly: a rating is not a score of how disabled you are as a person. It's the VA's estimate of how much your average earning capacity is affected compared to an unimpaired worker your age. That's why the functional evidence — what you can and can't do — drives the individual ratings before any math happens.

Checking Your Own Letter

You can verify the math yourself: list each condition and its percentage, combine them by the "percentages of what's left" method (or the VA's published table), apply the bilateral factor for paired limbs if applicable, and round to the nearest 10%. If your result differs from the letter's, that's a concrete, checkable question — and exactly the kind of thing an accredited VSO reviews for free. Our podcast episode "Combined Ratings and the Bilateral Factor" walks the whole calculation with real numbers, and the Free VA Claims Quick-Start Guide at standeasynetwork.com shows you how to pull the file the math came from.
