The median pay is about $256,560 a year. Across everyone in the job it runs from about $73,570 at the lower end to about $475,430 at the upper end. The source is listed under Sources at the end of this page.
13 to 14 years after high school, on the usual route.
$195,000 to $330,000 all in for tuition, fees, exams and kit. Living costs are not counted.

The national median is $256,560 a year, the bottom tenth earn $73,570 or less and the top tenth $475,430 or more, in the 2025 federal wage survey. The wage survey does not count endocrinologists separately. It lumps them in with general internal medicine physicians, so this is the figure for that whole group.

Resident pay in years 1 to 4 at UC San Diego (University of California San Diego), 2025 to 2026
You are a paid hospital employee for five or six years after medical school, through residency and fellowship. Each hospital sets its own scale, and this one is in a high cost city. Nationally, the AAMC (Association of American Medical Colleges) survey of 345 teaching hospitals puts the average first-year stipend at $68,166 as of July 1, 2025, and about $81,807 in the fifth year. Read from the AAMC's data, downloaded in a browser with Claude in Chrome on 6 November 2026, because aamc.org refuses our checker.
Few procedures to bill
Most of the work is clinic visits, not operations or scopes
Doctors bill for visits and for procedures separately. Endocrinology is mostly history, lab results and long conversations, with few procedures, so income depends on clinic visits. Go in knowing that.
Roughly, all in
$195,000 to $330,000
Tuition, fees, exams and kit. Not rent, food or travel
The costs are the same as any medical path: a four year degree, the medical school entrance exam and applications, four years of medical school, and the national licensing and board exam fees. The low end is a community college start, an in state public university and an in state public medical school. The high end is a public university followed by a private medical school. Residency and the endocrinology fellowship are paid posts, so the extra specialty years cost you nothing in tuition. Public Service Loan Forgiveness after ten years at a nonprofit or public hospital can cancel the remaining federal balance.
Most graduates borrow, and the debt is large. Public Service Loan Forgiveness can help: 10 years at a nonprofit or public hospital on an income driven plan can wipe the balance.
Malpractice insurance paid
Covered by the hospital or the group, and cheaper in this specialty than in surgery.
Predictable hours
Clinic-based medicine. There is call, but you are rarely operating at 2am.
Loan repayment for shortage areas
Federal and state programs pay down student loans for doctors who work in underserved places, and endocrinology is short-staffed in most of the country.
Academic and research posts
Hormone research is where a lot of the best-known work in modern medicine happened, and university jobs are genuinely available.
The exact path from high school to qualified.
Thirteen or fourteen years after high school. Endocrinology is a subspecialty, so you become an internal medicine doctor first.
High school
Grades 11 and 12
Biology and chemistry above all, with the grades to get into a strong college program.
Bachelor's degree
4 years
Any major, as long as you finish the pre-medical science courses and sit the Medical College Admission Test (MCAT).
Medical school
4 years
Two years of science, two years of hospital rotations. You graduate as a Doctor of Medicine (MD) or a Doctor of Osteopathic Medicine (DO).
Internal medicine residency
3 years
Wards, clinics and intensive care. Paid, supervised, and the foundation for everything after.
Endocrinology fellowship
2 to 3 years
Endocrinology, diabetes and metabolism. Two years for clinical training, three if you add research.
Board certification
After each stage
Certify in internal medicine first with the American Board of Internal Medicine, then in endocrinology, diabetes and metabolism.
Chemistry
Hormones are chemistry. This is the specialty where that is literally true.
Biology
Feedback loops between glands are the whole mental model of the job.
Math and statistics
You will read lab trends and research papers every week for the rest of your career.
English
Half of this job is explaining a chronic illness to someone who did not ask for it.
Every state licenses doctors through its own medical board, and you hold a license in each state where you work. The exams are national: the three steps of the United States Medical Licensing Examination during medical school and residency, then board certification in internal medicine and again in endocrinology, diabetes and metabolism from the American Board of Internal Medicine. Both certifications have to be kept current with ongoing assessment for the rest of your career.
Things you don't need, but that help.
Diabetes
Both types, plus insulin pumps and continuous glucose monitors.
Thyroid disease
Overactive, underactive, nodules and thyroid cancer follow-up.
Bone and calcium
Osteoporosis, parathyroid disease and fracture prevention.
Pituitary and adrenal disorders
Rare, complicated, and the cases other doctors cannot work out.
Reproductive and growth hormones
Puberty, fertility and hormone therapy, often shared with other specialties.
Patience with long problems
Nobody is cured on the day you meet them. You are managing conditions for decades.
Comfort with data
Glucose monitors produce thousands of readings. Reading a pattern in them is a real skill.
Research during medical school
Fellowships are competitive and academic endocrinology runs on research.
A second language
Diabetes hits some communities much harder, and explaining a treatment plan badly is the same as not giving one.
If the subject interests you more than the 13 years, there are shorter ways in. Certified diabetes care and education specialists come from nursing, pharmacy or dietetics and do a lot of the day-to-day teaching. Nurse practitioners and physician assistants run diabetes clinics in many health systems. Dietitians sit at the center of the same problem. All of those take four to seven years after high school instead of thirteen.
Day to day, pros and cons, where you'd work.
Clinic. Fourteen to twenty appointments, most of them people you have known for years. You read glucose downloads before the patient sits down, then spend the visit working out why the numbers moved and what in their life caused it. Between patients you answer messages, adjust doses, chase lab results and argue with an insurer about a drug they will not cover. One or two new referrals a day are genuine puzzles nobody else could solve, and those are the reason people pick this specialty.
The good
The hard parts
Things people don't tell you.
Insulin was first given to a patient in 1922, and a disease that killed children within months became something people live with for decades. Almost everything endocrinology does follows from measuring and replacing hormones.
The brain tells a gland to release a hormone, the hormone tells the brain to stop asking. Working out which step in a loop has broken, from a handful of blood tests, is the core skill of the job.
A continuous glucose monitor records a reading every few minutes, day and night. Endocrinology went from guessing between three-month blood tests to reading a graph of someone's entire life, which changed both the medicine and the conversation.
Every list is built from the same numbers shown above, so you can see where this career sits next to the others.
