Best Student Loan Refinance Companies for 2026

Splash Financial is an online marketplace founded in 2013 in Cleveland, Ohio. Rather than lending directly, Splash connects you with a network of credit unions and banks — so by completing a single application, you can receive multiple offers and pick the best rate.

What sets Splash apart is how competitive the rates are, especially for borrowers with strong credit. The marketplace model means lenders are competing for your business, which tends to push rates lower than what you'd get applying to a single bank. They also offer up to 25-year terms, which is longer than most competitors and can significantly lower your monthly payment if cash flow is tight.

For medical professionals, Splash is particularly strong. Their medical resident refinancing program allows residents and fellows to pay just $100/month during training and for six months afterward. This is a lifesaver for doctors carrying six-figure debt on a resident's salary.

The prequalification process uses a soft credit check, so you can see your rates without any impact to your credit score. Splash also provides a dedicated customer support team — not a call center — so you get personalized help throughout the process.

SoFi is a full-service bank that also happens to be one of the biggest names in student loan refinancing. Unlike marketplace lenders, SoFi is a direct lender — meaning the entire process from application to loan servicing stays under one roof. That translates to a smoother experience and faster funding.

SoFi can refinance both federal and private student loans into a single payment. They offer competitive interest rates, and borrowers can stack two discounts: 0.25% for autopay and an additional 0.125% through SoFi Plus (available when you set up direct deposit to a SoFi checking account or pay the subscription fee). That combined 0.375% discount is one of the best in the industry.

Where SoFi really differentiates is the member benefits. They offer unemployment protection that lets you pause payments if you lose your job, plus career coaching and financial planning services. If you need a cosigner to qualify, SoFi is one of the few refinance lenders that allows it — which can help you land a lower rate if your credit is still developing.

There's no maximum loan amount, so even borrowers with high-balance graduate or professional school debt can refinance their full balance. Customer feedback is predominantly positive, and SoFi holds an “Excellent” rating on Trustpilot with over 10,000 reviews.

Earnest is the most flexible student loan refinancing lender on the market. While most lenders force you into standard 5, 10, 15, or 20-year terms, Earnest offers 180 custom term options — meaning you can dial in the exact monthly payment that fits your budget, down to the dollar.

Their fee structure is genuinely unmatched. No origination fees, no application fees, no prepayment penalties, and — uniquely — no late fees. That last part matters more than you'd think. If you hit a rough month and your payment is late, you won't get hit with a penalty on top of it.

Earnest also lets you skip one payment per year without penalty. The interest still accrues, but the payment itself is deferred — which gives you a real safety valve if something unexpected comes up. You can also switch between fixed and variable rates, and prepay at any time without cost.

Where Earnest really shines is their underwriting approach. Instead of just looking at your credit score and income, they factor in your savings habits, employment history, and overall financial behavior. This means borrowers with fair credit but strong financial fundamentals can still qualify — even if other lenders would turn them down. You can also refinance even if you didn't finish your degree, as long as you meet their other criteria.

LendKey takes a different approach than the big-name lenders. Instead of lending directly, they connect you with a network of 300+ community banks and credit unions — many of which are nonprofit institutions with lower overhead. That structural advantage often translates to competitive rates that big banks can't match.

The process is straightforward: check your rate in about two minutes with no credit impact, compare offers from LendKey's partner lenders, and pick the best one. Fixed and variable rates are available across 5 to 20-year terms, with no origination or prepayment fees. If you have an existing loan with one of their partner lenders, you may qualify for an additional 0.25% loyalty discount.

LendKey's strongest differentiator is the safety net. They offer up to 18 months of forbearance on 15 and 20-year loan terms — significantly more than most competitors. That extended forbearance means if you hit a financial rough patch, you have real breathing room. They also offer a cosigner release option after 24 on-time payments, so your cosigner doesn't stay on the hook forever.

Beyond the loan itself, LendKey provides free borrower benefits including career assistance, credit health analysis, and federal student loan guidance through their partnership with Savi. The customer support team is in-house and available in the evening — not just during business hours — which is a nice touch.
