Key Takeaways
- Refinancing before residency ends is almost always a mistake — you’ll likely forfeit IDR protections and PSLF eligibility during years when income-driven payments are lowest.
- A $250,000 loan at 7% refinanced to 5% saves roughly $43,000 in interest over a 10-year repayment term — but that math only works if you’re not on track for PSLF.
- Laurel Road and SoFi both offer physician-specific programs with reduced payments during residency, but read the rate footnotes: the advertised rates assume strong credit and often require auto-pay enrollment.
- Refinancing a federal loan into a private one is permanent. There is no reverse option.
The Refinancing Window Is Not When You Think
Most physicians who refinance their medical school loans do it too early. The residency match comes through, the loan balance is sitting at $280,000, and the instinct is to do something about it. Refinancing feels like action. It is often the wrong action.
Federal medical school loans come with income-driven repayment options, and during a three-to-seven-year residency on a $65,000 salary, those options matter. On the SAVE plan, a resident earning $65,000 with $250,000 in federal debt would have a monthly payment in the range of $350 to $450, a fraction of what a market-rate private loan would demand. The moment you refinance into a private loan, that floor disappears. So does any progress toward Public Service Loan Forgiveness.
The right window for most physicians is the six months after residency and fellowship end. You have verifiable attending income, your credit profile has had time to strengthen, and you know your employer. That last part is what most people skip.
Run the PSLF Math Before Anything Else
If you are joining a nonprofit hospital system or an academic medical center, you may qualify for Public Service Loan Forgiveness. PSLF forgives the remaining balance on federal Direct Loans after 120 qualifying monthly payments under an income-driven repayment plan, while employed full-time by a 501(c)(3) or government entity. The forgiven amount is not currently taxable as federal income.
Here is why this changes the refinance calculation entirely. A physician who completes a four-year residency and a two-year fellowship has already made six years of PSLF-qualifying payments, assuming they were on an IDR plan and working at a qualifying employer. That physician needs only four more years of payments as an attending before the remaining balance is forgiven. Refinancing at that stage, even to a meaningfully lower rate, means paying off a balance that would otherwise disappear.
Take a physician entering attending practice with $220,000 remaining on federal loans after residency payments. On an IDR plan at an attending salary of $250,000, the payment under SAVE is higher than during residency but still below what a private refi would require. Four years of those payments totals somewhere around $80,000 to $100,000 depending on income growth. The forgiven balance at year ten could be $160,000 or more. No refinance rate gets you there.
The PSLF path only makes sense if you stay at a qualifying employer for the full ten years. If you move to a private practice group or for-profit hospital system, the calculus flips, and refinancing as an attending becomes the right move.
The Worked Example: $250,000 at 7% vs. 5%
For physicians not on track for PSLF, the interest savings from refinancing can be substantial. Work through a realistic scenario: $250,000 in federal loans at a blended rate of 7%, refinanced at the start of attending practice to a fixed private rate of 5%, both on 10-year repayment terms.
At 7% over 10 years, the monthly payment on $250,000 is $2,903. Total interest paid over the life of the loan is $98,340. At 5%, the payment drops to $2,652, and total interest falls to $67,880. The difference is $30,460 in interest, plus $251 per month in cash flow. Extend to a 12-year term at 5% and the monthly payment drops further to $2,319, though total interest rises to $83,350, still saving roughly $15,000 against the 7% ten-year scenario.
Those are real numbers. A physician who refinances $250,000 from 7% to 5% and keeps the same 10-year payoff timeline walks away with more than $30,000 in their pocket compared to leaving the loans on the original federal terms. The question is always whether PSLF or IDR benefits would have been worth more.
Physician-Specific Lenders and What Their Footnotes Say
Five lenders dominate physician loan refinancing right now: Laurel Road, SoFi, Earnest, ELFI, and Splash Financial. They all market aggressively to doctors, and they all have product features worth understanding before you apply.
Laurel Road has the most explicitly physician-branded product. Their doctor loan refinancing program allows residents and fellows to make payments of $100 per month during training, then transitions to full amortization once you hit attending status. The advertised variable rates as of spring 2026 start around 5.49% APR and fixed rates around 5.74% APR. Laurel Road’s rate disclosure footnote specifies that those rates include a 0.25% auto-pay discount and assume a borrower with a credit score above 740. Lose the auto-pay and the rate ticks up immediately.
SoFi runs a similar residency deferment option and adds unemployment protection: if you lose your job, they’ll pause payments for up to 12 months. Their advertised fixed rates start around 5.24% APR for the most qualified borrowers, but the fine print confirms that rate assumes excellent credit, a co-signer in some scenarios, and auto-pay enrollment. SoFi also offers career coaching and financial planning access, which matters more to some borrowers than others.
Earnest allows you to set your own exact monthly payment within a range, which gives more control over payoff speed. Their rates are competitive, generally starting around 5.49% fixed for physicians with strong credit. Earnest does not use a hard credit score cutoff and considers income trajectory, which helps residents who are pre-attendings at application.
ELFI and Splash Financial tend to compete more aggressively on rate for larger loan balances. Splash in particular acts as a marketplace, matching your application to multiple lenders simultaneously, which means one soft pull can surface competing offers. For a $300,000+ loan, the difference between the second and third best offer can be half a percentage point, which adds up to real money over a decade.
A detail worth knowing from the inside of how these approvals work: lenders price physician loans partly on income trajectory, not just current income. A first-year attending in internal medicine and a first-year attending in orthopedic surgery will not always get the same rate offer even with identical credit scores, because lenders model projected repayment risk differently. Some lenders are more explicit about this than others, but it is happening in the underwriting whether or not the marketing says so.
Residency-Friendly Refinancing: The Reduced Payment Trap
Laurel Road and SoFi’s $100/month residency programs sound attractive. They are not always a good deal. During the period when you are paying $100/month on, say, $250,000 at 6%, roughly $1,250 in interest is accruing every month. The gap between your payment and the accruing interest is $1,150 per month, and it capitalizes onto your principal. A three-year residency with $100/month payments adds approximately $41,000 to your balance before you ever make a full payment.
Contrast that with staying on a federal IDR plan during residency, where the same physician might pay $400/month and interest subsidies under SAVE prevent the balance from ballooning. The federal option protects you better during training. The private residency programs are mostly useful for physicians who are ineligible for federal loans, already know they’re going into private practice, and have a strong reason to lock in a rate now rather than after training.
If you have federal loans and are still in residency, the right answer is almost always to stay federal, keep making IDR payments, and revisit the refinance question when you have an offer letter from your attending employer in hand.
Cosigner Release and the Other Reason Physicians Refinance
The interest savings narrative dominates physician refinancing content, but there is a second reason to refinance that matters to a significant share of medical school borrowers: releasing a parent or spouse who co-signed the original private medical school loans.
Many private medical school loans, particularly those taken out for the first two years of school before federal limits were maxed out, require a co-signer. That co-signer is on the hook for the full balance. Their credit report carries the debt. If the loan goes delinquent for any reason, it affects them.
Refinancing in your name alone as an attending physician, with verifiable income at $200,000 or above, is one clean transaction that removes that obligation entirely. You do not need a co-signer release clause in the original loan, you do not need to qualify through the original lender’s release process, and you do not need the original lender’s cooperation. The new loan is yours alone. For a parent who co-signed $80,000 in private loans a decade ago, that matters as much as the rate.
Federal Loans Are a One-Way Door
Refinancing a federal student loan into a private loan is permanent. There is no reconsolidation back into the federal system, no reinstatement of IDR eligibility, no path back to PSLF. The decision deserves that weight.
For physicians going into private practice, employed by for-profit hospital groups, or joining specialties with high enough income that forgiveness math simply does not pencil, refinancing is the right call. The savings are real, the rates are competitive, and the product features from the major physician lenders have improved meaningfully in the last several years.
For anyone with even a reasonable chance of spending ten years at a qualifying nonprofit employer, exhaust every federal option first. Run the PSLF numbers with a student loan attorney or a fee-only financial planner who works with physicians. The calculation is not complicated, but it is easy to get wrong when a lender’s rate offer is sitting in your inbox and looking appealing.
For physicians who want to compare current rates across lenders before deciding, private student loan rates gives a current overview of the market. And if you are still evaluating which private lenders have physician programs worth considering, best private student loans covers the broader competitive landscape with current rate data.
The refinance decision for physicians is not primarily about finding the lowest rate. It is about knowing whether you are in the group for whom refinancing is the right move at all. Get that part right first, and the rate comparison becomes straightforward.
