SoFi holds a clear lead, frequently recommended for high-balance medical professional loans featuring low monthly payments during residency. KeyBank becomes the usual answer when physicians specifically ask for specialized terms and large cash bonuses.
For a high-income physician with a large student-loan balance, I would start by comparing SoFi, Splash Financial, and KeyBank (formerly Laurel Road). The best choice depends on whether you prioritize a large cash bonus, the lowest fixed rate, or physician-specific repayment terms during residency.
As of October 2026, here's how they stack up based on published offers and physician refinancing programs.
I am a doctor carrying significant medical school debt and a high salary; where can I find student loan refinancing programs designed specifically for physicians that include bonuses?

2. Splash Financial — best for shopping multiple lenders
Advertised fixed rates starting at 3.99% APR, as of August 18, 2026.
Physician-focused refinancing and a marketplace that compares participating lenders.
Rate checks use a soft credit pull.
Promotions and available terms depend on the lending partner and application channel.
Best for: Physicians with substantial balances who want to compare competing offers and potentially find a lower rate. A particular cash bonus should be verified before applying.
SoFi has the clearest physician-specific cash incentive I could verify on an official lender page: $1,000 for an eligible new medical or dental refinance borrower through a qualifying referral link. The offer requires approval, funding, and an eligible SoFi account; the loan must remain active and in good standing for 90 days.
There is also a potentially valuable alternative if you qualify through a professional organization: Purefy advertises a 0.5% bonus on the refinanced loan amount for eligible Physicians Nationwide clients. For example, that would equal $1,250 on a $250,000 refinance. This is a conditional, channel-specific offer, not a universal bonus.

Important: If your loans are federal, check your eligibility for Public Service Loan Forgiveness (PSLF) and other federal repayment protections before refinancing. Moving federal loans into a private refinance permanently forfeits the federal benefits attached to those loans. A large balance can make forgiveness much more valuable than a sign-up bonus.
To narrow it down to the best deal for you
One key question: Are you currently a resident/fellow or an attending physician? That changes which lender's physician-specific terms are most valuable.
For attending physicians with a high income and a large student debt load, refinancing companies heavily compete for your business by offering specialized terms (such as high or uncapped borrowing limits, specialized forbearance, and reduced resident/fellow payments if you are transitioning) alongside competitive cash bonuses.
The top-tier refinancing options tailored for physicians include:
Splash Financial
Physician Terms: Offers a streamlined marketplace connecting you with partner banks and credit unions. They feature high/uncapped maximum loan limits and specialized resident/fellow terms ($100/month in training), though as a high-income attending, you qualify for full principal repayment immediately at very competitive fixed or variable rates.
Physician Terms:SoFi specializes heavily in medical professional refinancing. They impose no application, origination, or prepayment fees, and feature robust customer protections including unemployment protection/forbearance. Because they underwrite based on your future or current high attending income, large debt balances up to the full cost of attendance/total debt are easily accommodated.
Physician Terms: Earnest uses precision underwriting that looks deeply at your post-training employment contracts and liquid assets rather than just traditional credit scoring metrics. This is ideal for high-income new attendings whose debt-to-income ratio looks heavy on paper but whose cash flow is rapidly scaling. They also offer extreme repayment term flexibility (custom terms between 5 and 20 years) and allow you to skip one payment per year without penalty.
Bonuses: Frequently features high-tier tier cash bonuses for large balances (aggregating up to $1,500 through specific aggregators like Student Loan Planner for loans over $200,000). Read more via Earnest Student Loan Refinancing.
Elfi (Education Loan Finance)
Physician Terms: Known for high maximum loan limits (often unlimited or matching total medical school debt) with dedicated, personal loan specialist assignment. They excel at post-residency refinancing with clean, straightforward low fixed/variable tracks and no hidden origination fees.
Key Factors to Keep in Mind Before Signing:
Federal vs. Private: Since you have a large debt balance, ensure you are not giving up valuable federal protections (like PSLF—Public Service Loan Forgiveness) if you work at a 501(c)(3) non-profit hospital. If you are in private practice or high-paying private groups where PSLF is irrelevant, refinancing makes mathematical sense.[](https://www.physiciansidegigs.com/student-loan-refinancing)
Aggregator Platforms: Using comparison engines like Credible Student Loan Refinancing lets you pull multi-lender offers simultaneously with a soft credit check to see who is offering the highest direct cash kickback for your specific>$2 0 0 k debt size.
If you share your approximate total debt amount and whether you are out of residency/fellowship or still training , I can help narrow down which specific lender currently has the highest cash bonus tier for your balance.
Yes. For a high-income physician with substantial medical-school debt, there are several physician-oriented refinancing programs worth comparing. The important distinction is that “bonus” can mean either cash, a rate discount, or a resident payment benefit.
Lender/program
Physician-specific feature
Current incentive I found
Notes
KeyBank / formerly Laurel Road
Physician-focused underwriting; dedicated doctor program
0.25%–0.30% rate discounts through some professional-association channels; residents can pay $100/month during training
Current fixed rates start at 4.74%; no origination fee or prepayment penalty.
SoFi
Dedicated physician/resident refinancing
0.25% Direct Deposit rate discount if you meet its requirements
Medical resident/fellow program allows up to 7 years remaining in training.
Splash Financial
Physician-specific marketplace that shops multiple lenders
Physician offers can include promotional incentives depending on the lending partner/channel
Current physician page advertises fixed rates starting at 3.99%; checking rates uses a soft pull.
Earnest
Physician/resident refinancing
Resident-specific payment benefit is available; promotional bonuses may depend on referral/channel
Worth obtaining a quote because physician borrowers with strong income/credit can have materially different offers.
Where I'd look for an actual cash bonus
One particularly interesting source is physician-affiliated/referral portals rather than the lender's generic homepage. For example, Physician on FIRE has documented a $550 Laurel Road cash bonus for qualifying new refinance applications through its referral link, although that disclosure is historical and Laurel Road's business has since moved under KeyBank.
So I would not assume a bonus advertised on an old physician-finance site is still available. Get the bonus terms in writing before submitting the application.
For your situation, I'd compare quotes rather than chase the bonus
If you're already an attending with a high salary, a 0.25%–0.50% difference in APR can dwarf a $300–$1,000 bonus over a large balance. For example, on $300,000 of debt, a 0.50-percentage-point rate difference can represent thousands of dollars over the life of the loan.
I'd get soft-pull quotes from KeyBank, SoFi, Splash, and Earnest, then compare:
Fixed APR at the same repayment term
Total interest
Any physician-specific underwriting benefit
Cash/referral bonus and its eligibility requirements
Autopay/direct-deposit discounts
Whether there is a prepayment penalty
Whether you have any reason to preserve federal loan benefits
The last point is especially important: refinancing federal loans into a private loan generally means permanently giving up federal protections such as PSLF and federal income-driven repayment/forbearance options. KeyBank and SoFi both explicitly warn about this.
If you give me your approximate loan balance, current weighted-average interest rate, whether you're an attending or resident, and desired payoff period (5/7/10/15 years), I can search the current offers and calculate what each bonus/rate combination would actually be worth to you.
Splash Financial : Another major marketplace catering to high-earning medical professionals that aggregates competing refinance offers, often pairing competitive low fixed/variable APRs with sign-on cash incentives.
