Medical school is one of the most rewarding — and most expensive — paths in American higher education. Four years of tuition, fees, and living expenses, followed by several years of residency on a modest salary, means most future physicians borrow heavily and borrow early. Understanding medical school loans before you sign your first promissory note can save you tens of thousands of dollars in interest and years of repayment stress later.
This complete borrowing guide explains how medical students pay for school in 2026: federal Direct and Grad PLUS loans, annual and lifetime limits, private loan options, how interest behaves during residency, and repayment strategies designed for doctors.
How Much Do Medical Students Borrow?
Total medical school costs vary widely. Public medical schools with in-state tuition are substantially cheaper than private schools and out-of-state options, but even the lower-cost path often requires significant borrowing once living expenses are included. Over four years, total costs commonly reach into the low-to-mid six figures, and at private schools in high-cost cities the full cost of attendance can be considerably higher.
As a result, many graduates finish medical school owing roughly in the $150,000 to $250,000 range, and some owe more, especially when undergraduate loans are added. Family support, scholarships, and lower-cost public schools can bring the total down sharply.
Step 1: File the FAFSA and Exhaust Free Money First
Every medical student should file the FAFSA each year, even if you expect to rely mainly on loans. The FAFSA is the gateway to federal loans and to some institutional aid. Before borrowing:
- Apply for school-based scholarships and need-based grants, which vary greatly by institution.
- Ask about service-commitment programs, such as the National Health Service Corps and military health professions scholarships, which can cover tuition in exchange for a service obligation.
Federal Loans for Medical School
Most medical students finance the bulk of their education with two federal loan programs. Both are applied for through your school after you file the FAFSA.
Direct Unsubsidized Loans
Graduate and professional students can borrow Direct Unsubsidized Loans each year up to the annual limit set for their program. Medical students may have access to a higher limit — confirm the exact figure with your financial aid office.
For 2025-26, the interest rate on Direct Unsubsidized Loans for graduate students is 7.94%. The rate is fixed for the life of that loan, but rates for new loans reset every July 1, so each year’s borrowing may carry a different rate. Check current rates at studentaid.gov. Interest accrues from disbursement, and there is a small origination fee deducted from each disbursement.
Grad PLUS Loans
When Direct Loans and other aid are not enough, Grad PLUS Loans can cover up to the full cost of attendance minus other aid received. That makes Grad PLUS the workhorse loan for many medical students in years three and four, when costs remain high and savings run low.
For 2025-26, Grad PLUS Loans carry an 8.94% interest rate, plus an origination fee that is higher than the fee on Direct Unsubsidized Loans. Grad PLUS requires a credit check for adverse credit history. A credit check is not the same as the income and credit-score underwriting private lenders use, but an adverse history can lead to denial unless you obtain an endorser or document extenuating circumstances.
Because Grad PLUS costs more, the usual order of borrowing is: scholarships and grants first, Direct Unsubsidized Loans second, and Grad PLUS only for the remaining gap. If you are comparing that order with other graduate programs, our guide to how much law school costs shows the same federal structure applied to a JD.
Private Medical School Loans: When Do They Make Sense?
Private student loans are offered by banks, credit unions, and online lenders. They may advertise lower interest rates than Grad PLUS, especially for borrowers — or cosigners — with excellent credit.
The trade-off is protection. Private loans generally do not offer:
- Income-driven repayment tied to your residency salary
- Public Service Loan Forgiveness
- The same deferment, forbearance, and discharge options as federal loans
Those federal protections are unusually valuable in medicine, because many physicians train and later work at nonprofit hospitals and academic medical centers that can qualify for Public Service Loan Forgiveness. Read our comparison of Grad PLUS vs. private loans before replacing federal borrowing with a private offer that only looks cheaper on rate alone.
Interest During School and Residency
Interest is where medical school debt grows quietly. Because federal graduate loans are unsubsidized, interest accrues while you are in school, during the six-month grace period after graduation, and during residency unless you make payments.
Consider the pattern, not just the principal:
- Four years of borrowing means your earliest loans accrue interest the longest.
- Unpaid interest capitalizes at certain points — for example when a repayment or deferment period ends — after which you pay interest on a larger balance.
- Residency often lasts three to seven years, depending on specialty, on a salary that makes full standard payments difficult for high-balance borrowers.
Even modest payments in residency can help. Paying just the interest, or enrolling in an income-driven plan with payments based on your residency salary, can slow growth and keep more options open. If you are still choosing a health career, comparing costs with our physician assistant program cost guide can put medical school borrowing in perspective — PA programs are shorter and usually require far less debt.
Repayment Strategies for Doctors
Income-driven repayment during residency
Federal income-driven plans base your payment on income and family size, which can make payments manageable on a resident’s salary. Payments made during residency at a qualifying nonprofit employer can also count toward Public Service Loan Forgiveness, giving residents a valuable head start.
Public Service Loan Forgiveness (PSLF)
PSLF forgives the remaining federal loan balance after 120 qualifying payments while working full-time for a qualifying government or nonprofit employer. Many teaching hospitals qualify. If you plan to pursue PSLF, keep federal loans federal, certify employment regularly, and stay on a qualifying repayment plan.
Refinancing after training
Once you are an attending physician with a strong income and you are certain you do not need federal protections or forgiveness, refinancing federal loans into a lower-rate private loan can reduce interest costs. Refinancing is permanent — you cannot move private loans back into the federal system — so most doctors wait until after residency and after the PSLF decision is clear.
A Borrowing Checklist for Every Year of Medical School
- Review your school’s official cost of attendance and build a real monthly budget below it where you can — every dollar not borrowed saves more than a dollar.
- Accept only the loan amount you need; you can reduce or return funds within the school’s deadlines.
- Track each loan’s rate and balance in your studentaid.gov account, and revisit your repayment strategy in your final year.
Frequently Asked Questions
What is the interest rate on medical school loans in 2025-26?
For 2025-26, federal Direct Unsubsidized Loans for graduate and professional students carry a 7.94% rate, and Grad PLUS Loans carry 8.94%. For comparison, the undergraduate Direct Loan rate for 2025-26 is 6.39%. Rates for new loans reset every July 1; confirm the current year’s rates at studentaid.gov.
How much can I borrow in Grad PLUS?
Up to your school’s cost of attendance minus any other financial aid you receive, subject to a credit check for adverse credit history.
Should I pay interest while in residency?
For most residents, making income-driven payments is preferable to forbearance because it limits balance growth and can count toward loan forgiveness if you work for a qualifying employer.
Key Takeaways
- Borrow in order: free money first, Direct Unsubsidized Loans second, Grad PLUS for the remaining gap up to the cost of attendance.
- 2025-26 federal rates are 7.94% for graduate unsubsidized loans and 8.94% for Grad PLUS; rates reset every July 1.
- Private loans may offer lower rates to excellent-credit borrowers but lack income-driven repayment and Public Service Loan Forgiveness.
- Income-driven repayment during residency usually beats forbearance, and refinancing is best considered only after training.
