Key Takeaways
- Refinancing private-to-private is a pure rate shop — you have no federal protections to lose, so the only question is whether you can get a better rate.
- On a $40,000 loan refinanced from 9% to 6% over 10 years, you save roughly $7,000 in total interest — about $58 per month.
- Prequalify with at least three lenders before you apply. The soft-pull prequalification costs you nothing and the rate spread between lenders on the same borrower can be 1.5 percentage points or more.
- Most refinances close in one to four weeks, but keep making payments on your original loans until your new servicer confirms the transfer is complete.
Can you refinance a private student loan? Yes. The process is more straightforward than most borrowers expect, because there is nothing to give up. Federal loans carry income-driven repayment, forgiveness programs, and forbearance protections that disappear the moment you refinance them into a private loan. Private loans carry none of those protections to begin with. When you refinance a private loan into another private loan, you are doing one thing: shopping for a lower interest rate, or better terms, or both.
There is no federal refinance program for private student loans. The Department of Education handles federal loans only. If someone has pitched you a “government refinance” for your private debt, that pitch is wrong. Your path runs through private lenders, SoFi, Earnest, ELFI, LendKey, Splash Financial, Laurel Road, and others who compete aggressively for creditworthy borrowers.
Why Private-to-Private Refinancing Is the Easier Case
Borrowers who hold only private loans, or who have already separated their private debt from any federal loans they carry, are in the cleanest possible refinancing position. The decision tree collapses down to one question: is the new rate meaningfully lower than the old one? If yes, and if the repayment term makes sense for your cash flow, you refinance. If no, you don’t.
The triggers worth acting on are predictable. Rates have dropped since you borrowed. Private student loan rates move with broader credit markets, and if you took out loans during a high-rate environment, a refinance is worth pricing out. Your credit score has improved materially since origination, which is common if you were a 22-year-old with a thin file when you first borrowed and now have several years of payment history behind you. You want to release a cosigner, since many lenders offer a cosigner release path through refinancing that is faster than the release clause in your original loan. Or you have loans with three different servicers, and you are tired of making three payments, tracking three autopay discounts, and fielding three sets of customer service calls.
Any one of those reasons is enough to start the process.
Step One: Pull All Your Current Loan Information
Before you talk to a single lender, sit down with every private loan statement you have. Write down the lender name, current servicer (these are not always the same entity), outstanding balance, interest rate, whether the rate is fixed or variable, and the remaining repayment term. If you have a cosigner on any loan, note that too, because some refinance lenders will ask about it.
This matters operationally, not just organizationally. Lenders will ask for your total private loan balance and your current rates during prequalification. If you give them fuzzy numbers, you get fuzzy rate quotes. I have seen borrowers walk into a refinance conversation thinking their rate was “around 8%” only to dig up their original note and find it was 9.4% variable with a cap at 14%. That gap changes the math considerably.
If you cannot locate your original loan documents, your current servicer is required to provide them. Call and ask for your promissory note and current payoff statement. Servicers are used to this request.
Step Two: Prequalify With at Least Three Lenders
Prequalification uses a soft credit pull, which does not affect your credit score. Every major refinance lender offers it. You fill out a short form with your income, employment, loan balance, and basic personal information, and within minutes you get a rate range. The hard pull comes later, when you formally apply and accept an offer.
Do not prequalify with one lender and stop. The spread between lenders quoting the same borrower is real. SoFi, Earnest, and Splash Financial all serve the refinance market, but they price risk differently and source capital differently. LendKey is worth a specific mention because it connects borrowers with credit unions and community banks rather than direct lenders, and credit unions frequently offer rates that the bigger-name lenders cannot match, particularly for borrowers in the mid-700s credit score range who are not getting quoted the headline rates anywhere else.
When you look at a lender’s advertised rate, read the footnote. The “as low as” rate on refinance lender homepages typically assumes a borrower with a credit score above 750, a debt-to-income ratio well below 20%, and autopay enrollment. Earnest, for example, includes a 0.25% autopay discount in its advertised rates; the footnote on its rate disclosure page says so. SoFi does the same. If you are comparing offers, make sure you are comparing apples to apples: all rates with autopay, or all rates without it.
Here is what that 0.25% autopay discount actually means on a real loan. Take a $40,000 refinance at 6.25% over 10 years. The monthly payment is $445. At 6.0% with the autopay discount applied, the payment drops to $444, but over the life of the loan, that quarter point saves you about $530. Not life-changing, but the discount is free money as long as you do not let autopay lapse. Critically: if your loan is ever transferred to a new servicer, your autopay enrollment does not transfer with it. You have to re-enroll, and until you do, the discount is gone.
Step Three: Work the Math on Your Actual Loans
The sample numbers in the editorial pitch are worth spelling out fully because they are realistic for borrowers who took out private loans at peak rates in 2022 or 2023.
A $40,000 private student loan at 9% over a 10-year term carries a monthly payment of $507. Total interest paid over the life of the loan: roughly $20,800. Refinance that same balance to 6% over the same 10-year term, and the monthly payment falls to $444. Total interest paid: about $13,300. The savings is approximately $7,500 over the life of the loan, and the borrower frees up $63 per month starting immediately.
That is not a trivial sum. Seven thousand dollars is a used car, a year of groceries, or the start of an emergency fund. The calculation is not complicated; the point is that most borrowers never run it, which means they never know whether it is worth spending an afternoon on prequalification forms.
If you want to check your own numbers before applying anywhere, a standard amortization calculator handles this in about 30 seconds. Input your current balance, current rate, and remaining term. Then input the same balance, your quoted refi rate, and your target term. Subtract. That is your potential savings, ignoring any origination fees, which most student loan refinance lenders do not charge. Check anyway.
Step Four: Choose an Offer and Apply
Once you have prequalification quotes from at least three lenders, you are making a real decision, not guessing. Choose based on rate first, then look at the term options each lender allows, and then customer service reputation. A lender who offers a 5.8% rate but only on a 5-year term that produces a $750 monthly payment you cannot afford is not actually the better offer.
Some borrowers split the difference on term: refinance into a shorter term to pay down principal faster if cash flow allows, or extend the term to lower the monthly payment if the immediate cash flow matters more. Just be aware that extending your term lowers your payment but increases total interest paid, even at the lower rate.
When you formally apply, you will need documentation. Your current loan statements showing outstanding balances. Proof of income, typically two to three recent pay stubs or, if self-employed, two years of tax returns. Proof of employment, usually a recent pay stub suffices, though some lenders want an employment verification letter. A government-issued ID. Some lenders will also ask for your most recent bank statement to verify liquid assets.
The hard credit pull happens at application. If you plan to apply to more than one lender, do it within a short window. FICO treats multiple student loan inquiries within a 45-day window as a single inquiry for scoring purposes, so applying to three lenders in the same week does less damage to your score than applying to one lender in January and a second in April.
Step Five: Complete the Loan Transfer
Once you are approved and you sign the new loan agreement, your new lender contacts your old servicer and pays off your existing loan. This takes time. The typical timeline from application to first payment on the new loan runs one to four weeks, with most straightforward cases landing around two to three weeks.
Do not stop paying your original loans during this window. Until your new lender confirms in writing that your old loan has been paid in full and the account is closed, you are still the borrower on record. Missing a payment during the transfer period can generate a late fee, and depending on your servicer’s reporting timeline, a mark on your credit. Check your old account for a zero balance before canceling autopay there.
Once the transfer is confirmed, set up autopay on the new account immediately, both to recapture any rate discount and to protect your payment history going forward.
The Lenders Worth Looking At
For borrowers refinancing private-to-private, the best private student loans comparison will show you current offers in detail. A few lenders stand out for specific borrower profiles.
SoFi is strong for borrowers with high incomes and good credit who want a well-known servicer and a broad range of term options. Earnest lets borrowers customize their repayment term to the month rather than being locked into 5, 7, or 10-year increments, which can be genuinely useful if you want to pay off in 84 months instead of 84 or 120. ELFI has consistently offered competitive rates for borrowers in the upper credit tiers and has a straightforward application process. LendKey’s credit union network tends to produce surprisingly competitive rates for borrowers who do not have perfect credit profiles. Splash Financial has positioned itself as a marketplace that shops your application across multiple lenders, which is efficient if you want to reduce the number of separate forms you fill out. Laurel Road focuses on healthcare professionals and offers rate discounts for doctors and nurses, which matters a lot if you are a physician carrying significant private debt from medical school.
None of these lenders charge origination fees for student loan refinancing. Confirm that before you apply anywhere.
One Thing Lenders Will Not Tell You Upfront
Refinancing resets your loan’s clock. If you have been paying on a 10-year private loan for four years, you have six years of principal paydown behind you and momentum on your side. Refinancing into a new 10-year loan means you are starting a new amortization schedule, which front-loads interest again. Even at a lower rate, extending your repayment horizon can cost more in total interest than keeping your original loan.
The right move in that situation is usually to refinance into a term equal to or shorter than your remaining original term, not a fresh 10-year. A four-year-in borrower who refinances into a 5 or 6-year term at a lower rate gets the rate benefit without the amortization reset penalty. Lenders will not volunteer this framing. They will offer you their full menu of terms and let you choose.
