Refinancing replaces your current loan with a new one, usually at a different interest rate and term
When you refinance a student loan, you take out a new loan from a private lender to pay off your existing federal or private loan in full. The new loan has its own interest rate, repayment term, and monthly payment. You then repay only the new loan, not the original one.
The goal is usually to lower your interest rate, reduce your monthly payment, or shorten how long you'll be paying. But refinancing also means giving up certain protections that come with federal loans—income-driven repayment plans, forgiveness programs, and deferment options. Private lenders do not offer these.
Refinancing is permanent. Once you refinance a federal loan into a private one, you cannot convert it back. This is the single most important thing to understand before you move forward.
Key Takeaways
- Refinancing replaces your current loan with a new private loan, and you lose access to federal protections like income-driven repayment and Public Service Loan Forgiveness.
- Your new interest rate depends on your credit score, income, and debt-to-income ratio—lenders pull a hard credit inquiry, which temporarily lowers your score.
- You can refinance federal loans, private loans, or both, but refinancing federal loans is usually only worth it if your credit has improved significantly since you borrowed.
- The refinancing process takes one to three weeks from application to funding, and your old loan is paid off automatically once the new lender receives the funds.
- Refinancing makes sense if you have a stable income, good credit, and no plans to use federal repayment or forgiveness programs; it does not make sense if you may need income-based payments or are pursuing forgiveness.
How your interest rate and monthly payment change
Your new interest rate is based on your credit score, income, employment history, and debt-to-income ratio. Lenders typically offer rates between 4% and 8%, though the exact rate you receive depends on how much risk the lender sees in lending to you. A higher credit score and lower debt-to-income ratio generally mean a lower rate.
Your monthly payment is calculated from three things: the new loan amount (what you still owe), the new interest rate, and the new repayment term you choose. If you refinance into a shorter term—say, from 10 years to 5 years—your monthly payment goes up but you pay less interest overall. If you extend the term, your payment drops but you pay more interest over time.
The lender will show you several term options before you commit. Compare the total interest you'll pay across each option, not just the monthly payment. A payment that looks lower might cost you thousands more in interest if the term is much longer.
What you lose when you refinance federal loans
Federal student loans come with protections that private lenders do not offer. If you refinance a federal loan into a private one, you lose all of them permanently.
Income-driven repayment plans let you cap your monthly payment at 10% to 20% of your discretionary income. If your income drops or you face hardship, your payment adjusts downward. Private lenders do not offer income-based payments—your payment stays the same regardless of what you earn.
Public Service Loan Forgiveness (PSLF) erases remaining federal loan balance after 120 may have access to payments if you work for a government agency or nonprofit. Refinancing into a private loan disqualifies you permanently. If you have any chance of working in public service, do not refinance.
Deferment and forbearance let you pause or reduce federal loan payments during hardship, unemployment, or economic difficulty. Private lenders rarely offer these options, and when they do, they charge interest during the pause. Federal loans do not.
Loan forgiveness after 20 to 25 years of income-driven repayment erases any remaining balance on federal loans. Private loans have no forgiveness option—you must repay the full amount or default.
When refinancing makes financial sense
Refinancing is worth considering if your credit score has improved since you took out your original loan, or if you have a stable income and want to lock in a lower rate. Run the numbers: if the new interest rate is at least 0.5% lower than your current rate, refinancing usually saves money over the life of the loan.
Use an online calculator to compare your current loan (total interest paid, monthly payment) against the refinanced loan under different term options. Most lenders' websites have these calculators and show you an estimated rate before you formally apply.
Refinancing also makes sense if you want to shorten your repayment term and can afford a higher monthly payment. Paying off a loan in 5 years instead of 10 means paying significantly less interest, even if the rate stays the same.
When refinancing is a bad idea
Do not refinance if you are pursuing Public Service Loan Forgiveness or any other federal forgiveness program. Refinancing disqualifies you permanently, and the forgiveness benefit is usually worth far more than any interest savings.
Do not refinance if your income is unstable or you may need to use income-driven repayment in the future. Once you refinance, you cannot go back to federal protections. If you lose your job or face a pay cut, your private loan payment stays the same.
Do not refinance if your credit score is still low or you have recent late payments. Refinancing with poor credit means paying a higher interest rate than you currently have, which defeats the purpose. Wait until your credit improves—typically six months to a year of on-time payments.
Do not refinance if you have federal loans with a low interest rate already. Federal rates are often lower than private rates, especially for older loans. Refinancing into a private loan at a higher rate costs you money.
The refinancing process and timeline
Start by gathering your loan documents: your current loan balance, interest rate, and monthly payment. You'll also need recent pay stubs, tax returns, and employment information. Most lenders let you check your estimated rate online without a hard credit pull—this is called a soft inquiry and does not affect your credit score.
Once you decide to move forward, the lender pulls a hard credit inquiry, which temporarily lowers your score by a few points. You then complete a full application, and the lender verifies your income and employment. This step usually takes three to five business days.
After approval, the lender sends funds directly to your current loan servicer to pay off the old loan in full. You do not handle this payment yourself. Once the old loan is paid off, you begin repaying the new loan according to your chosen term. The entire process from application to funding typically takes one to three weeks.
Your first payment on the new loan is usually due 30 to 45 days after funding. During this time, you do not make payments on the old loan—it is already paid off.
Comparing refinancing to other options
Before refinancing, consider whether income-driven repayment might work better for you. If your income is moderate or you expect it to change, an income-driven plan can lower your payment without giving up federal protections. You can always refinance later if your situation improves.
If you have both federal and private loans, you can refinance only the private ones and keep your federal loans intact. This preserves your access to federal protections while potentially lowering the rate on private debt. Many borrowers do this as a middle ground.
If you are struggling with payments, look into federal consolidation (Direct Consolidation Loan) before refinancing. Consolidation combines multiple federal loans into one, lowers your payment through income-driven repayment, and keeps you in the federal system. Refinancing is the opposite—it moves you out of the federal system entirely.
Frequently Asked Questions
Will refinancing hurt my credit score?
Yes, temporarily. The hard credit inquiry lowers your score by a few points, usually for three to six months. Multiple applications in a short time (within 14 to 45 days, depending on the scoring model) count as a single inquiry, so shop around quickly if you are comparing lenders. Your score recovers as you make on-time payments on the new loan.
Can I refinance if I have a cosigner on my original loan?
Yes, but the cosigner may need to be involved in the refinancing process. Some lenders require the cosigner to co-sign the new loan; others let you refinance without them. Ask the lender before you apply. If you refinance without the cosigner, they are released from the original loan once it is paid off.
What if I want to refinance but my income is too low?
Most lenders have minimum income requirements, usually $24,000 to $30,000 per year. If you do not meet this, you may need a cosigner with may have access to income. Alternatively, wait until your income increases, or use federal income-driven repayment instead of refinancing.
Can I refinance private student loans?
Yes. Private loans have no federal protections to lose, so refinancing is purely a financial decision. If you can get a lower rate or better terms, refinancing a private loan is usually straightforward. The process is the same as refinancing federal loans.
What happens if I cannot afford the new payment?
Unlike federal loans, private lenders have limited options for payment reduction. Some offer forbearance or temporary payment reductions during hardship, but these are not may provide and usually come with interest charges. Before refinancing, make sure you can afford the payment you are committing to.
