Student loan refinancing replaces one or more existing loans with a new private loan at a lower interest rate. For borrowers with strong credit and stable income, refinancing can save thousands of dollars in interest over the life of the loan. The key trade-off: refinancing federal loans into a private loan permanently removes access to income-driven repayment plans and federal forgiveness programs.
Who Should Consider Refinancing
Student loan refinancing makes the most sense when:
- You have private student loans with high interest rates (7% or above)
- You have federal loans but do not plan to pursue forgiveness and have a stable income
- Your credit score is 680 or higher
- Your debt-to-income ratio is below 50%
- You want a lower monthly payment or want to pay off debt faster
If you have federal loans and work in public service, a non-profit, or government, do not refinance. You would lose eligibility for Public Service Loan Forgiveness (PSLF), which can forgive your entire remaining balance after 10 years of qualifying payments.
Best Student Loan Refinancing Companies of 2026
SoFi — Best Overall
SoFi is one of the largest student loan refinance lenders and consistently earns top marks for rates, member benefits, and customer experience. Fixed rates start around 4.99% APR and variable rates start around 5.99% APR for the most qualified borrowers. SoFi offers unemployment protection — if you lose your job, you can pause payments for up to 12 months total. There are no origination fees or prepayment penalties. SoFi also offers career coaching, financial planning access, and referral bonuses for members.
Best for: Borrowers with strong credit who want the best combination of rates and member perks.
Earnest — Best for Flexible Repayment
Earnest lets you choose your own monthly payment (within a range) instead of forcing you to pick from preset loan terms. You can pick a payment amount and Earnest shows you the resulting payoff date. You can also skip one payment per year with no penalty. Earnest uses a holistic underwriting model that considers your savings habits, career trajectory, and earning potential in addition to credit score — beneficial for recent graduates with thin credit files.
Best for: Borrowers who want precise control over their monthly payment and repayment timeline.
Laurel Road — Best for Healthcare Professionals
Laurel Road, a division of KeyBank, offers specialized programs for physicians, dentists, nurses, and other healthcare professionals. Residents and fellows can refinance at reduced payments during training — as low as $100 per month — then transition to full payments when earning a full attending salary. Medical professionals carry some of the highest student debt balances in the country, and Laurel Road’s programs are specifically built for their income trajectory.
Best for: Medical and dental borrowers who want a lender that understands physician income timing.
NaviRefi — Best No-Fee Option
NaviRefi is the refinancing arm of Navient (one of the largest federal student loan servicers) and offers a clean, no-fee product with competitive rates. There are no origination fees, no prepayment penalties, and no application fees. Rates are competitive, particularly for borrowers in the 700+ credit score range. Customer service is accessible and the application is straightforward.
Best for: Borrowers who want a simple, no-frills refinance from an established servicer.
CommonBond — Best for Graduate Borrowers
CommonBond focuses on graduate degree holders (MBA, JD, medical, engineering) and has underwriting criteria built for higher-balance loans. Fixed rates are competitive for borrowers with strong credentials. CommonBond also offers a social promise — for every loan funded, it contributes to education funding for students in need through its partnership with Pencils of Promise.
Best for: Graduate borrowers with higher loan balances who want a mission-driven lender.
ELFI (Education Loan Finance) — Best Rate Transparency
ELFI offers some of the lowest published rates for student loan refinancing and provides each applicant with a dedicated loan advisor rather than a call center experience. ELFI’s rates are consistently competitive and it has no hidden fees. The personal advisor model is useful for borrowers with complex situations — multiple loans, non-standard income, or self-employment.
Best for: Borrowers who want to work with a dedicated advisor and get transparent rate quotes.
Federal vs. Private Loans: The Refinancing Trade-Off
This is the most important decision in student loan refinancing. Federal loans come with protections that private loans do not:
- Income-driven repayment plans (IDR, PAYE, SAVE) that cap payments at a percentage of income
- Public Service Loan Forgiveness (PSLF) — full forgiveness after 10 years in public service
- Income-Based Repayment forgiveness after 20–25 years
- Federal forbearance and deferment options during hardship
Once you refinance federal loans into a private loan, these protections are permanently gone. If your financial situation changes, you have fewer safety nets. For borrowers with stable, growing incomes and no intention to pursue forgiveness, this trade-off is usually acceptable. For borrowers with variable income, government jobs, or large balances relative to income, it often is not.
How to Qualify for the Best Rates
- Credit score: Rates below 5% typically require a 750+ credit score. A 700–749 score still gets competitive rates — often 5.5%–6.5%.
- Debt-to-income ratio: Lenders want to see your total monthly debt payments below 43%–50% of gross monthly income.
- Employment stability: Full-time employment or consistent self-employment income helps. Recent graduates may need a cosigner.
- Degree completion: Most lenders require you to have completed your degree. Some lenders make exceptions for borrowers close to completion with demonstrated income.
How to Compare Refinancing Offers
Get pre-qualified with at least three lenders. Pre-qualification uses a soft credit pull and does not affect your score. Compare:
- APR (the true cost, including any fees)
- Loan term options
- Whether rates are fixed or variable
- Hardship options (forbearance, deferment, unemployment protection)
- Autopay discount (typically 0.25% rate reduction)
Bottom Line
Student loan refinancing can save significant money for borrowers with strong credit and private loans — or federal loans with stable income and no forgiveness plans. SoFi and Earnest are the best starting points for most borrowers. Healthcare professionals should look at Laurel Road first. Always get multiple quotes, apply the autopay discount, and run the numbers carefully before giving up federal loan protections.
