What refinancing does and who it helps
Refinancing means taking out a new loan from a private lender to pay off one or more existing student loans. The new loan replaces your old one entirely — you stop making payments to your original lender and start making them to the new one instead.
Refinancing works best if you have a steady income, a credit score of roughly 650 or higher, and federal loans you no longer need the protections on. The main reason to refinance is to lower your interest rate, which reduces what you pay over the life of the loan. A lower rate also means smaller monthly payments, or you can keep payments the same and pay off the loan faster.
Refinancing does not work for everyone. If you have federal loans and rely on income-driven repayment plans, Public Service Loan Forgiveness, or the ability to pause payments during hardship, refinancing into a private loan means losing those options permanently. Once you refinance federal loans into a private loan, you cannot convert them back.
Key Takeaways
- Refinancing replaces your existing student loans with a new private loan, and you only benefit if the new interest rate is lower than what you currently pay.
- Private lenders check your credit score and income before offering a rate, so your actual rate depends on your financial profile, not just the lender's advertised range.
- Refinancing federal loans means losing income-driven repayment, Public Service Loan Forgiveness may be able to access, and the ability to pause payments during hardship.
- The refinancing process takes one to two weeks from process to funding, and you can compare offers from multiple lenders without damaging your credit score if you do it within 14 to 45 days.
- Refinancing makes sense only if your new rate is at least 0.5 to 1 percentage point lower than your current rate, because closing costs and lost federal protections offset smaller savings.
How interest rates and monthly payments change
Your new interest rate depends on three things: the lender's current rates, your credit score, and your debt-to-income ratio. Lenders publish rate ranges — for example, 5.50% to 8.75% — but you only find out your actual rate after they pull your credit report and review your income. Two people with the same lender may receive different rates based on their financial profile.
The lower your rate, the more you save. If you currently pay 7% on a $50,000 loan over 10 years, your monthly payment is roughly $580 and you pay about $19,400 in interest. If you refinance at 5.5%, your monthly payment drops to about $530 and you pay roughly $13,600 in interest — a savings of nearly $6,000 over the life of the loan. But if you refinance at 6.9%, you save only about $600, which may not justify the time and the loss of federal protections.
Some lenders offer variable-rate loans, where your interest rate changes based on market conditions. Variable rates start lower than fixed rates but can increase over time, sometimes significantly. Fixed-rate loans keep the same rate for the entire loan term, so your payment never changes. Most borrowers choose fixed rates because the payment is predictable.
What you need before you start
Lenders require proof of income, employment, and identity. Have your most recent tax return or pay stubs ready — most ask for the last two months of pay stubs or your last year's tax return. You will also need your Social Security number and a government-issued ID.
You do not need to pay anything upfront. Legitimate refinancing lenders do not charge process fees, origination fees, or prepayment penalties. Some lenders offer small incentives like rate discounts for setting up automatic payments or for being a customer at their bank, but these are optional and not required to refinance.
Before you explore, gather your current loan documents or log into your loan servicer's website to find your current interest rate, remaining balance, and loan term. Knowing these numbers lets you calculate whether the new rate actually saves you money. You can also check your credit score for free through AnnualCreditReport.com or through your bank or credit card issuer.
The process and approval timeline
The refinancing process typically takes one to two weeks from process to funding. On day one, you complete an online process with basic financial information. The lender pulls your credit report and verifies your income — this usually happens within 24 to 48 hours. You receive a loan offer with your rate, monthly payment, and loan term options.
Once you accept the offer, the lender orders a final verification of employment and income, then prepares loan documents for you to sign electronically. You review and sign these documents, usually within three to five business days. After you sign, the lender sends the money directly to your current loan servicer to pay off your old loans. Your new loan servicer then sets up your first payment, which typically starts 30 to 60 days after funding.
You can explore with multiple lenders to compare offers. If you submit applications within 14 to 45 days, the credit inquiries count as a single inquiry for credit-scoring purposes, so shopping around does not damage your score. After 45 days, each inquiry counts separately and can lower your score slightly.
When refinancing costs you money instead of saving it
Refinancing has hidden costs that reduce your savings. If you currently have federal loans and refinance into a private loan, you lose access to income-driven repayment plans, which cap your payment at 10% to 20% of your discretionary income. You also lose the option to pause payments during unemployment, disability, or economic hardship. If your income drops or you face a job loss, a private lender will not pause your payments — you must keep paying or risk default.
You also lose Public Service Loan Forgiveness if you work in government or nonprofit jobs. PSLF forgives remaining federal loan balances after 120 may have access to payments, but only for federal loans. Once you refinance into a private loan, you can never use PSLF, even if you refinance back to federal loans later.
Some lenders charge prepayment penalties if you pay off the loan early, though this is uncommon. Always check the loan documents for prepayment penalties before you sign. If you plan to pay off the loan faster than the stated term, a prepayment penalty can eliminate your savings.
Comparing lenders and loan terms
The major private student loan refinancers include SoFi, Earnin, LendingClub, Splash Financial, and CommonBond. Each has different rate ranges, minimum loan amounts, and term options. Some lenders require a minimum loan balance of $5,000 or $10,000, while others have no minimum. Some offer terms as short as five years or as long as 20 years.
When comparing offers, look at three numbers: the interest rate, the monthly payment, and the total interest paid over the life of the loan. A lender with a slightly higher rate but a longer term option might give you a lower monthly payment, which matters if cash flow is tight. A lender with a lower rate but a shorter term might cost less overall but strain your monthly budget.
Some lenders offer perks like rate discounts for automatic payments, unemployment protection that pauses payments for a few months if you lose your job, or cosigner release after a certain number of on-time payments. These perks rarely change the decision, but they can matter if two lenders offer nearly identical rates.
Deciding whether to refinance your federal loans
Refinancing federal loans makes sense only if all three of these are true: your new interest rate is at least 0.5 to 1 percentage point lower than your current rate, you have a stable income and emergency savings, and you do not need income-driven repayment or Public Service Loan Forgiveness.
If you are unsure whether you will use PSLF, do not refinance yet. PSLF forgives remaining balances after 120 may have access to payments in government or nonprofit work. If you might change jobs or careers, keeping federal loans open preserves that option. Once you refinance to a private loan, you lose PSLF forever.
If your income is variable or you have less than three to six months of emergency savings, refinancing adds risk. Private lenders do not pause payments during hardship, so if your income drops, you still owe the full payment. Federal loans offer income-driven repayment as a safety net; private loans do not.
Frequently Asked Questions
Does refinancing hurt my credit score?
Refinancing causes a small, temporary dip in your credit score because lenders pull your credit report. The dip is usually five to 10 points and recovers within a few months. If you explore with multiple lenders within 14 to 45 days, the inquiries count as one, so shopping around does not multiply the damage.
Can I refinance federal loans and keep some of them federal?
Yes. You can refinance some federal loans and leave others alone. This is useful if you want to refinance high-interest federal loans but keep lower-interest ones or loans you might use for PSLF. Just tell the lender which loans to refinance during the process.
What happens if I cannot make a payment on my refinanced loan?
Private lenders do not offer income-driven repayment or hardship deferment. If you miss a payment, the lender reports it to credit bureaus and may charge late fees. After 90 days of missed payments, the loan goes into default and the lender can pursue collection. Federal loans offer much more flexibility during financial hardship.
Can I refinance private student loans?
Yes, you can refinance private loans the same way you refinance federal loans. Private lenders will refinance other lenders' private loans if your credit score and income may have access to. This is useful if you have high-interest private loans and can get a better rate elsewhere.
What if my new lender goes out of business?
If your lender fails, your loan is typically sold to another servicer and you continue making payments to the new servicer. Your loan terms do not change. This happens rarely, but it is why you should keep copies of your loan documents and know your loan balance and interest rate.
