Medical school loans work in two stages: while you’re enrolled, you borrow mostly through two federal programs that cover tuition and living costs; after you graduate, you repay through a standard ten-year schedule, an income-driven plan tied to your salary, or a service-based forgiveness track. Understanding how medical school loans work matters because total costs typically run between $286,000 and $391,000 over four years depending on whether the school is public or private,1Association of American Medical Colleges. Medical Student Education: Debt, Costs, and Loan Repayment Fact Card for the Class of 2024 and the median debt for borrowers at graduation sits around $205,000. The choices you make about how to borrow, whether to pay interest during training, and which repayment path to take can shift the final cost by tens of thousands of dollars.
What You Can Borrow
The federal Direct Loan Program, authorized under the Higher Education Act, is the main source of funding for medical students.2eCFR. 34 CFR Part 685 – William D. Ford Federal Direct Loan Program Two federal loan types do the heavy lifting, and private loans sit on the margins.
Direct Unsubsidized Loans
Graduate and professional students can borrow up to $20,500 per academic year in Direct Unsubsidized Loans.3Federal Student Aid. How Much Money Can I Borrow in Federal Student Loans? Medical students get a meaningful bonus: because allopathic and osteopathic programs are classified as health professions programs, you can borrow an additional $20,000 for a nine-month academic year, or up to $26,667 for a twelve-month year, on top of the $20,500 base.4Federal Student Aid. Annual and Aggregate Loan Limits A nine-month program allows up to $40,500 in Direct Unsubsidized Loans; a twelve-month program allows up to $47,167. Interest rates are fixed each year based on the May 10-year Treasury auction plus a statutory markup, and once a disbursement year locks in, that rate stays for the life of the loan. An origination fee is deducted from each disbursement, so the amount deposited is slightly less than the amount owed.
Direct PLUS Loans (Grad PLUS)
When unsubsidized loans don’t cover the full bill, Grad PLUS fills the gap. There is no fixed annual cap; you can borrow up to the school’s cost of attendance minus any other aid.3Federal Student Aid. How Much Money Can I Borrow in Federal Student Loans? Grad PLUS requires its own application and a credit check for adverse history. A perfect score isn’t needed, but bankruptcy, foreclosure, or accounts currently 90+ days delinquent can produce a denial. A denied applicant can still qualify with an endorser or by documenting extenuating circumstances. Grad PLUS carries a higher interest rate and a steeper origination fee than Direct Unsubsidized Loans, so maxing out unsubsidized borrowing first saves money.
Private Loans
Private lenders are an alternative when federal aid falls short. They are credit-based, with competitive rates generally reserved for borrowers with FICO scores in the mid-600s and above. Private loans almost never offer income-driven repayment, forgiveness programs, or the mandatory residency forbearance available on federal loans, and they lack federal death and disability discharge protections. Exhaust federal eligibility before taking a private loan.
How You Actually Get the Money
Every federal loan starts with the Free Application for Federal Student Aid. You complete the FAFSA online at studentaid.gov, and the form pulls your tax data directly from the IRS rather than requiring manual entry.5Federal Student Aid. Do You Need Money for College or Career/Trade School? For graduate students, financial need is largely beside the point—unsubsidized and PLUS loans are available regardless—but the FAFSA is still the mandatory gateway.
After the FAFSA is processed, two additional steps on studentaid.gov unlock disbursement. The first is the Master Promissory Note, a binding legal agreement to repay the loan plus accrued interest. A single MPN can cover multiple disbursements for up to ten years. The second is entrance counseling, an interactive session walking through your repayment obligations, interest, and borrower rights.6Federal Student Aid. What Is the Status of My Master Promissory Note (MPN)? Schools will not release funds until both are complete.
From there, your financial aid office handles disbursement. Funds arrive about a week before classes each semester, go directly to the school’s bursar, and are applied first to tuition and mandatory fees. Anything left over is refunded to you, usually by direct deposit, for housing, books, equipment, and living costs. Because the origination fee is already taken out, the refund is smaller than the raw loan figure suggests.
What Happens to Interest While You Train
The piece most borrowers underestimate is how much interest builds between the first disbursement and the first real payment, which for most physicians is roughly eight to nine years later.
In-School Deferment and the Grace Period
While you’re enrolled at least half-time, you’re in in-school deferment and no payments are required. After graduation or dropping below half-time, a six-month grace period begins before payments start.7Federal Student Aid. Grace Periods, Deferment, and Forbearance in Detail Interest accrues on both Direct Unsubsidized and Grad PLUS loans throughout both periods. You don’t have to pay it, but it’s accumulating the entire time.
Residency Forbearance
Residency creates a cash-flow problem. Deferment ends at graduation, but a resident’s salary—often between $60,000 and $75,000 before taxes—struggles to support full payments on $200,000-plus in debt. Federal regulations require servicers to grant forbearance in yearly increments to borrowers in medical internship or residency programs for the length of training.8eCFR. 34 CFR 682.211 – Forbearance Interest continues to accrue in forbearance. Many residents therefore skip forbearance and enroll in an income-driven plan so their lower payments at least count toward eventual forgiveness.
Capitalization
When deferment, the grace period, or forbearance ends, any unpaid interest is added to your principal. That’s capitalization, and from there interest begins accruing on the new, higher balance. A student who borrows $250,000 at roughly 7–8% and defers payments through four years of school and the grace period can see $60,000 or more capitalize before making the first payment. Making even interest-only payments during school or residency reduces this effect significantly.
Repayment Plans After Graduation
Repayment officially begins when the grace period ends, which for most new physicians falls early in residency. You’re placed on the Standard Repayment Plan automatically unless you choose a different one.
Standard Repayment
The Standard Plan sets fixed monthly payments calculated to pay off the balance over ten years.9Federal Student Aid. Standard Repayment Plan It minimizes total interest but produces payments above $2,000 a month on a $200,000 balance, which is difficult to manage on a resident salary.
Income-Driven Repayment
Income-driven repayment plans tie monthly payments to earnings rather than balance. The payment is a percentage of discretionary income, defined as the gap between your adjusted gross income and a set multiple of the federal poverty guideline. Pay As You Earn (PAYE) and Income-Based Repayment (IBR) for borrowers who took out loans after July 2014 set payments at 10% of that amount. Income-Contingent Repayment (ICR) uses a higher percentage. Any remaining balance is forgiven after 20 or 25 years of qualifying payments, depending on the plan.
For a resident earning $65,000, an IDR payment might be a few hundred dollars rather than $2,000-plus. The tradeoff is more total interest over the loan’s life, unless forgiveness arrives before the balance is paid off.
Marriage changes the math. Most IDR plans use joint income if you and your spouse file taxes jointly. Filing separately can lower the payment substantially if your spouse earns more, but filing separately also costs you certain tax credits and deductions, so run both scenarios.10Federal Student Aid. 4 Things to Know About Marriage and Student Loan Debt
One boundary worth knowing: the Saving on a Valuable Education (SAVE) plan is not currently a usable option. Courts blocked key provisions, and in December 2025 the Department of Education announced a proposed settlement that would end SAVE entirely.11Edfinancial Services. Saving on a Valuable Education (SAVE) Plan Enrolled borrowers were moved into administrative forbearance pending the settlement. Compare PAYE, IBR, and ICR instead using the Loan Simulator at studentaid.gov.
Forgiveness Paths That Change the Math
Two forgiveness programs can reshape a physician’s debt picture: Public Service Loan Forgiveness and the National Health Service Corps.
Public Service Loan Forgiveness
After 120 qualifying monthly payments made while working full-time for a qualifying employer, the remaining balance on your Direct Loans is forgiven in full—principal and accrued interest.12eCFR. 34 CFR 685.219 – Public Service Loan Forgiveness Program Qualifying employers include federal, state, local, and tribal government agencies and organizations designated as tax-exempt under section 501(c)(3) of the Internal Revenue Code. Most academic medical centers, nonprofit hospital systems, and VA hospitals qualify.
The 120 payments don’t need to be consecutive. Residency payments on an IDR plan count as long as the employer qualifies. A physician who makes IDR payments through a three-year residency at a nonprofit hospital already has 36 payments banked and needs 84 more as an attending. On a $250,000 loan, forgiveness can easily exceed $150,000.
Documentation discipline is what makes or breaks PSLF. Submit a PSLF certification form every year and whenever you change employers so qualifying payments are tracked in real time.13Federal Student Aid. Become a Public Service Loan Forgiveness (PSLF) Help Tool Ninja The PSLF Help Tool on studentaid.gov allows digital signing and submission. Waiting until the end to file everything is how borrowers discover that payments they assumed counted don’t.
National Health Service Corps
The NHSC Loan Repayment Program is available to licensed primary care providers who work in a Health Professional Shortage Area. In exchange for a two-year full-time service commitment, primary care physicians can receive up to $75,000 toward their student loans. Behavioral and oral health providers receive up to $50,000 for the same commitment, and continuation contracts extend the award.14Health Resources and Services Administration. Fiscal Year 2026 NHSC Loan Repayment Program Application and Program Guidance
Students can apply earlier through NHSC Students to Service. Final-year students at an accredited allopathic or osteopathic school who commit to an NHSC-approved primary care residency in a field like family medicine, internal medicine, pediatrics, or psychiatry can qualify.15Health Resources and Services Administration. National Health Service Corps Students to Service Loan Repayment Program Fiscal Year 2026 Application and Program Guidance NHSC and PSLF are separate programs, and many NHSC-approved sites also qualify for PSLF, so the two can often stack.
The Tax Trap at the End of IDR
Starting January 1, 2026, the federal tax exclusion for forgiven student loan debt created by the American Rescue Plan Act expired. Any balance forgiven through an income-driven repayment plan after that date may be treated as taxable income by the IRS.16NASFAA. Welcome to 2026: Some Student Loan Forgiveness Is Now Taxable If $150,000 is forgiven after 20 years on PAYE, the IRS could treat it as $150,000 of additional income in the year of forgiveness, producing a tax bill in the $30,000 to $50,000 range depending on other income and bracket.
PSLF forgiveness is not affected. Balances forgiven under PSLF remain tax-free under federal law regardless of when forgiveness occurs,16NASFAA. Welcome to 2026: Some Student Loan Forgiveness Is Now Taxable which widens the gap between PSLF and time-based IDR forgiveness. State treatment is a separate question: some states follow federal rules automatically, others set their own, and states with no income tax are not a concern. Check your state before building a long-term strategy around IDR forgiveness.
Consolidation and Refinancing
Federal Direct Consolidation combines multiple federal loans into one, with a new rate equal to the weighted average of the old rates rounded up to the nearest one-eighth of a percent. Consolidation is a convenience move, not an interest-saving one. It can also reset payment counts, so consolidating mid-way through an IDR plan may cost you credit toward PSLF or IDR forgiveness. Think carefully before consolidating if forgiveness is in your plan.
Private refinancing is a different decision with permanent consequences. A private lender pays off your federal loans and issues a new private loan, often at a lower rate for borrowers with strong credit and high income. The tradeoff is that you lose IDR, PSLF, residency forbearance, and federal death and disability discharge, and that loss can’t be undone. For an attending with no interest in forgiveness, refinancing can save real money. For a resident still years from full earning potential, it’s almost always premature.
