Medical school is one of the most expensive graduate degrees in the United States, and the sticker price is only the beginning. Tuition, fees, health insurance, rent, food, transportation, and lost wages over four years stack up fast — and most students finance a large share of it with federal Grad PLUS and private loans. This medical school cost calculator rolls all of those pieces into one number: what your education actually costs, what you will still owe after scholarships, and what that debt grows into after interest.
Adjust the sliders and the result card updates instantly. Compare a public in-state program against a private one, stress-test a higher interest rate, or stretch the repayment term to see how much interest a longer loan adds.
How to Use
- Enter Annual Tuition & Fees. Use your school's "Cost of Attendance" figure, not just the tuition line — mandatory fees, student health insurance, and lab/clinical fees are almost always bundled in. The national average for private medical schools is around $65,000 per year.
- Set Annual Living Expenses. Housing, food, transport, and personal costs in a college town can add $25,000–$35,000 per year. Leave the default $30,000 if you do not have a tighter budget.
- Choose Program Length. Most MD programs are exactly four years; combined BA/MD or MSTP tracks may differ.
- Enter Scholarships & Grants as a total dollar amount across the whole program — this is free aid you do not pay back.
- Set your Loan Interest Rate (APR). Federal Grad PLUS loans recently averaged around 7–8%, while medical-school refinancing after residency can drop to 5–6%.
- Pick your Loan Repayment Term. The standard 10-year plan has the highest monthly bill but the lowest total interest; a 25-year extended plan lowers the payment but roughly doubles lifetime interest.
- Optionally add your Residency Annual Salary for context — typical resident pay is about $60,000, which frames how the monthly loan payment will feel during training.
The result card shows the total cost of attendance, the net cost after aid, the amount financed, your projected monthly payment, the total you will repay over the full term, and the interest alone.
The Loan Repayment Formula
Once you know how much you have to borrow, the monthly payment uses the standard amortization formula every US servicer applies:
M = P × r(1 + r)ⁿ / ((1 + r)ⁿ − 1)
Where:
- M is the monthly payment.
- P is the loan balance you finance (net cost after scholarships).
- r is the monthly interest rate — the annual APR divided by 12.
- n is the number of monthly payments — the repayment term in years times 12.
Worked example: borrow $340,000 at 7.0% over 25 years. The monthly rate is 0.07 / 12 = 0.005833, and n = 300. Plugging in gives a monthly payment of about $2,403, and over 25 years you repay roughly $720,915 — meaning interest alone is about $380,915, more than the original principal. That is why refinancing from 7% down to 5% after residency can save well over $100,000.
If the rate is 0%, the formula divides by zero, so the engine simply splits the principal evenly: $340,000 over 300 months is $1,133.33 per month.
What Drives the Total Bill
Two schools with the same diploma can cost hundreds of thousands of dollars apart:
- Tuition & fees — private med schools average roughly $65,000/yr; public in-state schools are often $35,000–$45,000/yr, while out-of-state public tuition approaches private levels.
- Cost of living — a school in a high-cost metro can add $10,000+ per year over a midwestern campus.
- Scholarships & grants — merit awards, need-based aid, National Health Service Corps scholarships, and military scholarships all reduce the principal dollar-for-dollar.
- Interest — because medical loans accrue during school, unpaid interest can capitalize onto the principal at graduation, inflating what you repay.
A $380,000 four-year cost at $40,000 of aid leaves a $340,000 loan. At 7% over 25 years that becomes roughly $721,000 repaid — which is why residents planning ahead often target refinancing, PSLF qualification, or an income-driven plan.
Examples
Example 1 — The default profile. A student pays $65,000/yr tuition and $30,000/yr living costs over 4 years, receiving $40,000 in scholarships. Total cost of attendance is $380,000, net cost $340,000. At 7% over 25 years, the monthly payment is about $2,403, and total repayment is near $720,915 — roughly $380,915 of interest.
Example 2 — In-state savings. The same student attends a public in-state school at $40,000/yr tuition with $30,000/yr living. Four-year cost is $280,000; with the same $40,000 aid, the loan is $240,000. At 7% over 25 years the monthly payment falls to about $1,696 and total repayment to roughly $509,000 — saving over $210,000 compared with the private track.
Example 3 — Sticker shock at a top-cost program. At $200,000/yr tuition plus $100,000/yr living, four-year attendance hits $1,200,000. Even after $40,000 of aid, the $1,160,000 balance at 7% over 25 years demands about $8,199 per month and repays near $2.46 million. Running this number before you commit prevents sticker shock years later.
FAQ
How much does medical school actually cost?
The total cost of attendance is tuition plus fees plus living expenses multiplied by the program length. A typical private-med-school student pays roughly $65,000/yr in tuition and $30,000/yr in living costs, for a four-year total near $380,000 before aid. Public in-state programs commonly run $250,000–$300,000 total.
How much will I owe after scholarships and grants?
Subtract your total scholarships, grants, and tuition waivers from the four-year cost of attendance. That remainder is your net cost, and it is the principal you will likely finance. For example, $380,000 of cost minus $40,000 of aid leaves $340,000 to borrow.
What is the typical monthly student loan payment for a doctor?
On a $340,000 balance at 7% over a 25-year extended plan, the monthly payment is about $2,400. On a standard 10-year plan the payment jumps to roughly $3,960, but total interest paid falls from about $381,000 to around $135,000. Residents often choose income-driven plans during training and refinance once attending salary starts.
Is a 10-year or 25-year loan term better?
A 10-year term has a much higher monthly payment but costs far less total interest; a 25-year term lowers the monthly bill (critical during residency on a ~$60,000 salary) but can double lifetime interest. Choose the shorter term if you can comfortably afford it; choose the extended or income-driven plan if cash flow during residency is tight, then refinance to a lower rate once your attending income begins.
Do medical students pay interest while in school?
Yes. Unsubsidized federal and Grad PLUS loans accrue interest during medical school. If you do not pay that interest as it builds, it capitalizes — it is added to your principal at graduation — which means you pay interest on interest. Making even small interest payments during school can meaningfully cut your final balance.
How does residency salary affect repayment?
Residents typically earn about $60,000 per year, which makes a $2,400–$4,000 monthly loan payment feel heavy. Many residents use income-driven repayment (IBR/PAYE/SAVE) during training, then switch to the standard plan or refinance once attending compensation begins, which is usually $200,000+.
Should I refinance my medical school loans?
Refinancing can drop the rate from ~7.5% to ~5–6% and save six figures over the life of the loan, but it forfeits federal protections such as PSLF, income-driven forgiveness, and forbearance. Refinance if you have a stable attending job, do not plan to work in public service, and can lock a lower fixed rate.
