Burnout vs Depression: How They Overlap and Where They Differ
In this article
People usually search "burnout or depression" at a low point. Work has felt heavy for months, weekends no longer refill the tank, and somewhere along the way the question shifted from "how do I get through this week" to "is something wrong with me." The honest answer has two parts. The two overlap a great deal, enough that researchers still argue about where one ends and the other begins. And the difference still matters, because depression is a health condition that clinicians diagnose and treat, while burnout is defined by its link to work, which points toward a different set of fixes.
This piece sets out what each term means, why neither you nor your manager can reliably tell them apart by looking, and what two short self-checks on this site can and cannot tell you. None of it can tell you which one you have. Only a doctor or licensed clinician can do that, and the later sections cover when to go and what to bring.
Two definitions that start in different places
Burnout: an occupational phenomenon
The World Health Organization includes burnout in ICD-11, its international classification, as an occupational phenomenon. WHO is explicit that it is not classified as a medical condition. It sits in the chapter on factors that bring people into contact with health services, not among the illnesses.
The ICD-11 definition describes a syndrome resulting from chronic workplace stress that has not been successfully managed, with three dimensions:
- feelings of energy depletion or exhaustion
- increased mental distance from your job, or cynicism and negativity about it
- reduced professional efficacy, the sense that you no longer do the work well
WHO also limits the term to the occupational context. Exhaustion from caregiving or parenting is real, but it is not what ICD-11 means by burnout. Two things follow from the definition. Burnout says something about the job as well as the person. And because it is not a diagnosis, there is no agreed clinical threshold for "having" it. In the US, the DSM that clinicians use does not list burnout as a disorder either.
Depression: a health condition that reaches every part of life
Depression is a mental health condition, and a common one. WHO's depression fact sheet estimates that 5.2% of adults worldwide live with it. During a depressive episode, a person has a depressed mood (sad, irritable or empty) or a loss of pleasure or interest in activities, most of the day, nearly every day, for at least two weeks. Other symptoms can include poor concentration, excessive guilt or low self-worth, hopelessness about the future, disrupted sleep, changes in appetite or weight, tiredness, and thoughts about dying or suicide.
The important word there is "activities," not "work." Depression does not stay at the office. It follows people into weekends, hobbies, relationships and vacations. It can be set off by a hard job, a loss, an illness, or nothing anyone can point to. And unlike burnout, it is diagnosed and managed by clinicians. WHO describes psychological treatments as the first line, with antidepressant medicines added in moderate and severe cases.
Where the two overlap
Side by side, the overlap is plain. Exhaustion is the core of burnout and a listed symptom of depression. Mental distance from the job looks a lot like loss of interest. Reduced efficacy looks a lot like poor concentration and low self-worth. Sleep trouble and irritability turn up in both.
The research says the same thing in numbers. A 2019 systematic review and meta-analysis pooled 69 studies and found a correlation of 0.52 between burnout and depression scores. A correlation of 0.52 is strong by the standards of workplace research: people who score high on one measure tend to score high on the other. Square it, though, and you get about 0.27. The two scores share roughly a quarter of their variation, and the rest is not shared. The authors concluded that burnout and depression are connected but are not the same construct.
When I built wellbeing surveys, I saw the team-level version of this: exhaustion items and mood items moved together across teams, but not in lockstep. A team in a brutal quarter-end would light up on exhaustion and barely move on mood. Now and then a team showed the reverse, for reasons that had little to do with workload.
| Burnout (ICD-11 occupational phenomenon) | Depression (health condition) | |
|---|---|---|
| Status | Not classified as a medical condition | A diagnosable mental health condition |
| Scope | Work only, by definition | All areas of life |
| Core features | Exhaustion, distance or cynicism about the job, reduced efficacy | Low mood or loss of interest, most of the day, nearly every day, two weeks or more |
| Sleep, energy, concentration | Often affected | Often affected |
| Guilt, worthlessness, hopelessness | Not part of the definition | Common symptoms |
| Thoughts of death or suicide | Not part of the definition | A possible symptom that needs help right away |
| Who assesses it | No formal diagnosis | A doctor or licensed clinician |
| Where change usually starts | The job: workload, control, support, recovery time | Clinical care, plus changes to whatever is feeding it |
Treat the table as a sketch, not a decision tool. Real people rarely sit neatly in one column.
Why you cannot tell from the outside
Managers often ask some version of "how do I know if it's burnout or something more serious?" The truthful answer is that they cannot, and should not try.
From the outside, the two produce the same visible signals: withdrawal from meetings, more mistakes in familiar work, a shorter temper, more sick days, a flat tone in one-to-ones. A manager sees behavior at work, not whether the person enjoyed their weekend, is sleeping, or felt the heaviness lift on vacation. Those are exactly the details that separate the two, and they belong in a clinic, not a performance conversation. Diagnostic questions from a manager also create real risk under the ADA. The manager's job is to notice, ask in plain terms how the person is doing, look at what is within their control (workload, deadlines, support), and point to the EAP. Our field guide to early warning signs of burnout covers that conversation.
It is not much easier from the inside. Depression colors how you read your own life, so a depressed person can sincerely believe the job is the whole problem. Burnout that runs long enough can spread past work and pull mood down with it. And the two can exist together. Deciding on your own that "it's only burnout" can delay care that would help. Deciding "I must be depressed" can lead you to treat a staffing problem as a personal failing.
A few questions are still useful as clues to bring to a professional, not as answers:
- Does the heaviness lift on days off and vacations, even briefly, or does it come along?
- Can you still enjoy things that have nothing to do with work?
- Is the main feeling tiredness and frustration, or emptiness, guilt and hopelessness?
- Did it start or worsen with a specific change at work, or does it predate the job?

What the self-checks on this site measure
People often take our two free self-checks one after the other. They measure different things, and knowing what each asks makes the results easier to read.
The burnout self-check (Copenhagen Burnout Inventory)
Our burnout self-check uses the seven work-related questions from the Copenhagen Burnout Inventory, which its Danish authors published for free use. The items ask whether your work is emotionally exhausting, whether you feel worn out when the working day ends, whether you are exhausted in the morning at the thought of another day at work, whether every working hour is tiring, and whether you have energy left for family and friends. Each answer is scored from 0 to 100 and the seven are averaged. On our page, under 50 counts as low, 50 to 74.9 as moderate, and 75 or above as high.
Notice what is missing. The Copenhagen questions focus on exhaustion you attribute to work. They do not ask about guilt, appetite, hopelessness or thoughts of death, and they do not separately measure WHO's other two dimensions, cynicism and reduced efficacy. A high score says your work is wearing you down. It cannot say whether depression is also present.
The mood self-check (PHQ)
Our PHQ self-check uses the Patient Health Questionnaire, a widely used depression screener. It asks how often over the last two weeks you have been bothered by specific problems: little interest or pleasure, feeling down or hopeless, sleep changes, tiredness, appetite changes, feeling bad about yourself, trouble concentrating, and moving or speaking noticeably slower, or more restlessly, than usual. The questions follow the symptoms clinicians look for in depression, and they ask about your life in general, not your job.
The full PHQ-9 adds a ninth question about thoughts of being better off dead or of hurting yourself, and its scores run from 0 to 27. Our page runs the PHQ-8, which leaves that question out, because a web form cannot respond safely to a yes. Scores run from 0 to 24, with band edges at 5, 10, 15 and 20, and a score of 10 or more is the level commonly used to identify current depression in population studies.
A screener is a prompt, not a diagnosis. It flags a pattern worth taking to a clinician.
Reading the two results together
| Burnout score | PHQ score | What it may suggest | A sensible next step |
|---|---|---|---|
| High | Under 10 | Work-related exhaustion without many wider mood symptoms right now | Look hard at workload and recovery, talk with your manager or HR, check again in a month |
| High | 10 or more | Exhaustion at work alongside wider depressive symptoms | See a doctor or licensed clinician soon, and bring both results |
| Low or moderate | 10 or more | Mood symptoms that may not be mainly about work | See a doctor or licensed clinician, and do not assume work is the cause |
| Low or moderate | Under 10 | Neither pattern is strong right now | Keep an eye on it and check again if things change |
Wherever you land, if something feels wrong, trust that over a number. If work exhaustion is the main concern and your mood is holding up, our guide on how to recover from burnout goes further into what helps.
When to see a doctor
Make an appointment with your primary care doctor, a licensed counselor or therapist, or your employee assistance program (EAP) if any of these apply:
- low mood, emptiness or loss of interest on most days for two weeks or more
- the heaviness is there on weekends and vacations, not only at work
- changes in sleep, appetite or weight you cannot explain
- persistent guilt, worthlessness or hopelessness
- a PHQ score of 10 or more, or a burnout score of 75 or more
- you are struggling to get through ordinary days, at work or at home
- you are drinking more, or leaning on other substances, to cope
A doctor can also look for physical causes that mimic both, such as thyroid problems, anemia, sleep disorders or medication side effects. That alone is a reason to start with an appointment rather than a guess.
Bring notes: when this started, what changed at work or home around then, how you are sleeping, and your dated self-check scores. If cost or a waitlist is the barrier, the EAP is usually free and confidential, and it can often help you find a counselor your health plan covers.
If you have thoughts of death, suicide or hurting yourself, do not wait for an appointment. Call or text 988 to reach the 988 Suicide & Crisis Lifeline, which is free, confidential and open around the clock. If you are in immediate danger, call 911.
What employers should take from the distinction
For HR teams, the WHO definition carries a pointed message. Burnout comes from chronic workplace stress that has not been managed, which makes it partly the organization's problem, solved through workload, staffing, control over how work gets done, and recovery time. A resilience webinar touches none of those.
Depression is different ground. Employers should not try to identify it, screen individuals for it, or infer it from performance data. Their part is to keep routes to care open: a trusted EAP, benefits with real access, managers who know where to point, and accommodation requests handled properly. The same two moves serve both: fix what the job is doing to people, and make care easy to reach for whatever the job does not explain.
Frequently asked questions
Can burnout turn into depression?
The two often travel together, as the meta-analysis above shows. What research cannot do is tell you, as an individual, which came first or whether one caused the other. If exhaustion has started to spread beyond work into the rest of your life, treat that as a reason to see a clinician rather than waiting it out.
Should I tell my manager?
You do not have to share a diagnosis or a self-check score with anyone at work. Many people find it useful to talk about the work side (workload, deadlines, the hours) without going into health. If you need changes because of a health condition, you can ask HR about accommodations, which run through a separate, confidential process.
A book on where the two meet
One book sits right on the line this article draws. Johann Hari's Lost Connections (Amazon page) is a journalist's look at the social causes of depression and anxiety, including work that feels meaningless or out of your control. It offers a perspective, not a treatment plan, and it does not replace care from a clinician. How we chose it: from the author's background as a long-form reporter, the publisher's information, and published reviews, and for how directly it takes on work as one of the forces behind low mood.
