Federal vs private medical school loans: Complete comparison guide

Introduction

Medical school loans require a strategic choice: Federal loans generally offer superior protections for residents and Public Service Loan Forgiveness (PSLF) eligibility, while private loans may offer lower interest rates for borrowers with excellent credit who plan to enter private practice. This guide covers the complete comparison framework to help you choose the right financing path for your medical career.

You’ll learn how to weigh the safety nets of federal Income-Driven Repayment (IDR) plans against the potential cost savings of private lending. Whether you are a parent protecting your financial future or a student mapping out a residency budget, understanding these trade-offs is essential. By the end, you’ll be able to compare federal vs private options, model residency payments, and pick a funding path aligned with your specialty and career goals.

Context: Medical school financing landscape

Context: How medical school financing works today.

Medical school is a significant investment in human capital, with the Association of American Medical Colleges (AAMC) reporting that the total Cost of Attendance (COA) for four years typically ranges from $250,000 to over $400,000 as of late 2024. Because scholarships and grants rarely cover the full cost, most medical students rely on loans to bridge the gap. Unlike undergraduate financing, where limits are low, medical students can borrow up to the full cost of attendance through both federal and private channels.

Loans generally disburse at the start of each semester, sent directly to the school to cover tuition and fees, with the remainder refunded to the student for living expenses. It is important to note that interest rates and origination fees for federal loans update annually each July; we refresh our pages to reflect the 2024–2025 and upcoming 2025-2026 cycles.

At-a-glance: Quick decision framework

For many families and students, the decision comes down to career trajectory and risk tolerance. Here is a quick summary to help you orient yourself before diving into the details:

Federal medical school loans: Direct Unsubsidized and Grad PLUS

For the vast majority of medical students, federal loans form the foundation of their funding strategy. The U.S. Department of Education offers two primary loan types for graduate and professional students, both of which offer critical safety nets for the long training period required in medicine.

The Direct Unsubsidized Loan is the first loan medical students should utilize. According to StudentAid.gov, health profession students are eligible for higher annual borrowing limits than standard graduate students. As of the 2024-2025 academic year, medical students can borrow up to $40,500 per nine-month academic year (compared to the standard $20,500), with a higher aggregate lifetime limit of $224,000.

According to StudentAid.gov, these loans have a fixed interest rate of 8.08% for loans disbursed between July 1, 2024, and June 30, 2025, and a relatively low origination fee of 1.057% for loans disbursed before October 1, 2025. Crucially, they do not require a credit check or a cosigner.

Once you have maximized your Unsubsidized Loans, Grad PLUS Loans are available to cover the remaining Cost of Attendance. These loans require a basic credit check to ensure you do not have an “adverse credit history,” but they do not use your credit score to determine your interest rate.

According to StudentAid.gov, Grad PLUS loans carry higher costs: a fixed interest rate of 9.08% for the 2024-2025 academic year and a substantial origination fee of 4.228% as of October 2024. This high fee means that for every $10,000 you borrow, over $420 is deducted immediately, never reaching your bank account.

The primary reason to choose federal loans is flexibility during residency. Medical residents typically earn salaries that are low relative to their debt load. Federal loans are eligible for Income-Driven Repayment (IDR) plans, which can cap monthly payments at a percentage of your discretionary income. This ensures that loan payments remain affordable during residency.

Furthermore, federal loans are the only loans eligible for Public Service Loan Forgiveness (PSLF). Since many teaching hospitals and non-profit clinics qualify for PSLF, sticking with federal loans keeps the door open for tax-free forgiveness after 10 years of qualifying payments.

According to Betsy Mayotte, student loan expert, “In general, federal loans should be your first stop, but private loans can be appropriate when you’ve maxed out your federal eligibility.” This advice is particularly relevant for medical students who must navigate years of lower-income training before reaching peak earning potential.

Private medical school loans: Features and requirements

Private student loans are issued by banks, credit unions, and online lenders. While they lack the standardized protections of federal loans, they can offer competitive advantages for borrowers with strong financial profiles. Private student loans can cover up to 100% of the school-certified Cost of Attendance, similar to Grad PLUS loans.

Private lenders offer both fixed and variable interest rates. As of January 2025, highly qualified borrowers (or those with creditworthy cosigners) may qualify for fixed rates that are lower than the federal Grad PLUS rate, and occasionally lower than the Direct Unsubsidized rate. Unlike federal loans, private loans generally do not charge origination fees. This 0% fee can result in immediate savings compared to the ~4.2% fee on Grad PLUS loans.

Approval and pricing for private loans are based strictly on creditworthiness. Since most medical students do not have an income while in school, a cosigner is frequently required to secure the best rates. For parents, this is a significant consideration. If you cosign, the loan appears on your credit report, affecting your ability to borrow for other purposes (like a mortgage or car loan).

However, many private lenders offer “cosigner release” programs. After the student graduates, begins earning an income, and makes a set number of on-time payments (typically 12 to 48 months), the cosigner can be removed from the loan obligation.

Private lenders also innovate by offering specific “medical residency and relocation loans.” These are personal loans designed to cover the expensive transition between medical school graduation and the start of residency—expenses that federal student loans generally cannot cover because the student is no longer enrolled.

According to Mark Kantrowitz, financial aid expert, “Private loans can be a good option when federal loans don’t cover the full cost of attendance.” This makes them a strategic tool for filling specific funding gaps or for students who are ineligible for federal aid.

Key comparison points for medical students

To make an informed decision, you must compare how these loans behave during the specific lifecycle of a physician’s career. The differences in cost and flexibility can be dramatic.

Federal loans have a “one-size-fits-all” rate, while private loans price risk individually. If you have a cosigner with a credit score of 800+, a private loan might offer an interest rate 1–2% lower than a Grad PLUS loan. When you combine a lower interest rate with the absence of a 4.2% origination fee, the private loan can be mathematically cheaper if you pay it off in full. However, if interest rates rise, variable-rate private loans can become significantly more expensive than fixed-rate federal loans.

This is often the deciding factor.

• Federal: You can enter an IDR plan (like SAVE or IBR) during residency. If your resident stipend is ~$65,000, your monthly payment might be $300 or less. In some plans, unpaid interest is subsidized, preventing your balance from ballooning.
• Private: Private lenders typically offer a “residency deferment” or “forbearance” period where you pay either nothing or interest-only payments during residency. However, interest continues to accrue and capitalize, meaning your balance will grow. Once residency ends, you owe the full amortized payment immediately, which can be a shock to your budget.

If you plan to work in academic medicine, a non-profit hospital, or the VA system, you are likely eligible for Public Service Loan Forgiveness (PSLF). According to StudentAid.gov, this program forgives the remaining balance of your federal loans tax-free after 120 qualifying monthly payments. Private loans are never eligible for PSLF. If you borrow $300,000 privately, you must pay back every cent, plus interest.

Furthermore, federal loans offer discharge options for death and permanent disability. While some private lenders have added similar clauses, they are not guaranteed by law and vary by lender contract.

Some students choose a hybrid approach: they take federal loans during school to maintain safety and PSLF eligibility during residency. Then, once they become attending physicians with high incomes, they evaluate their debt. If they are not pursuing PSLF, they can refinance their federal loans into a private loan at that time to secure a lower interest rate. This strategy preserves options until you are financially secure.

Special considerations for medical career paths

Your intended specialty and career environment should heavily influence your borrowing strategy. The financial trajectory of a pediatrician in private practice differs vastly from a neurosurgeon in an academic research hospital.

Residency training lasts anywhere from 3 to 7+ years. According to AAMC data, the average first-year resident stipend is approximately $64,000 as of 2024. If you have a longer residency (like surgery) or pursue a fellowship, you will spend nearly a decade in this lower-income bracket. Federal IDR plans are essential here to keep payments manageable and to accumulate credit toward PSLF forgiveness.

The PSLF path (academic/non-profit): If you intend to work for a 501(c)(3) hospital or university, PSLF is likely your most financially efficient option. You should borrow 100% federal loans. Even if private loans have a lower interest rate, the savings rarely outweigh the benefit of having a significant portion of your principal forgiven tax-free.

The private practice path: If you are certain you will join a for-profit private group immediately after residency, PSLF is off the table. In this specific scenario, minimizing interest accrual becomes the priority. A private loan with a lower rate might save you money long-term, provided you can manage the payments during residency or negotiate a signing bonus to cover them.

Some states offer loan repayment assistance programs (LRAPs) for physicians working in Health Professional Shortage Areas (HPSAs). While many of these programs prefer federal loans, some state-based grants can be used to pay down private debt. Always check the specific requirements of the state medical board where you plan to practice.

Making your decision: A step-by-step framework

Navigating these options can be overwhelming. Use this step-by-step framework to determine the right mix for your situation.

File the FAFSA (complete the Free Application for Federal Student Aid online) and accept your Direct Unsubsidized Loans first. These offer the best balance of high limits, fixed rates, and lower fees without a credit check. Calculate how much money you still need for tuition and living expenses.

Do you or a cosigner have a credit score of 750+ and stable income? If yes, get a rate quote from private lenders to see if you can beat the current Grad PLUS interest rate and origination fee. If your credit is fair or you lack a cosigner, Grad PLUS is the clear choice.

Are you 100% certain you will go into private practice? If there is any chance you might work in a non-profit hospital, stay with federal loans to preserve PSLF eligibility. You can always refinance federal loans into private loans later, but you cannot convert private loans back to federal.

• Maximize Federal Unsubsidized: Yes, always.
• Gap Funding: Compare Grad PLUS vs. Private.
• Safety Check: If I don’t match or have to delay residency, can I afford the private loan payments?
• Cosigner Conversation: Is my parent willing and able to take on this debt risk for the next 5-10 years?

If the math favors private loans but the risk feels too high, remember: you can use Grad PLUS loans now and refinance them after you become an attending physician.

Frequently asked questions

Yes, but it is difficult. While some medical students with established credit histories or prior careers may qualify alone, most lenders view full-time students as high-risk due to lack of income. Some lenders have specific programs for medical students in their final year (M4) that base approval on future income, but for M1-M3, a creditworthy cosigner is usually necessary to secure competitive rates.

Both federal Grad PLUS and private loans can be used for living expenses up to the school’s Cost of Attendance. If you choose private loans for this purpose, ensure the lender offers a grace period that covers your entire medical school duration plus the initial months of residency. Be cautious about borrowing more than absolutely necessary, as living expenses accrue interest just like tuition debt.

Refinancing federal loans into private loans is generally recommended only after you have secured a high-paying attending position and have ruled out PSLF. Refinancing during residency converts your federal loans to private, causing you to lose access to income-driven repayment plans (like SAVE) that keep payments affordable on a resident’s salary.

According to StudentAid.gov, PSLF forgives the remaining balance on Direct Loans after 120 qualifying monthly payments while working full-time for a qualifying employer (typically 501(c)(3) non-profits or government organizations). Most residency programs at teaching hospitals qualify. This allows you to make low, income-based payments during residency that count toward the 10 years needed for forgiveness.

If you do not match, federal loans offer unemployment deferment, forbearance, or income-driven plans that can drop payments to $0 if you have no income. Private loans have much stricter repayment terms and limited forbearance options (often 12 months total over the life of the loan), making them riskier if your career path faces an unexpected delay.

Yes. A common strategy is to borrow the maximum in federal Direct Unsubsidized Loans (due to their lower fees and protections) and then use private loans to cover the remaining gap if the private rate is significantly lower than the Grad PLUS rate. This “hybrid” approach diversifies your debt portfolio.

Choosing between federal and private medical school loans is not just a math problem; it is a risk management decision. For most students, the federal loan pathway offers the most security, flexibility during residency, and potential for massive forgiveness through PSLF.

However, private loans play a vital role for families with strong credit who want to minimize interest costs, or for students committed to private practice careers who want to avoid high federal origination fees. The best strategy often involves maximizing your Direct Unsubsidized eligibility first, then carefully evaluating the remaining gap.

Key takeaways:

• Federal first: Always maximize Direct Unsubsidized Loans before looking elsewhere.
• Protect your residency: Federal IDR plans provide crucial cash flow flexibility during your training years.
• Know your path: PSLF candidates should strictly avoid private loans; private practice candidates can shop for savings.
• Refinance later: You can always turn federal loans into private loans later, but you can never go back.
