What Refinancing Means and Who Can Do It
Refinancing means taking out a new loan to pay off one or more existing student loans. A private lender gives you money, you use it to close your current loans, and then you owe the new lender instead. The terms — interest rate, monthly payment, and loan length — are different from what you had before.
You can refinance federal student loans, private student loans, or both at the same time. The new loan almost always comes from a private bank, credit union, or online lender, not from the federal government. Even if you refinance a federal loan into a private one, you lose access to federal protections and repayment plans.
Lenders decide whether to refinance you based on your credit score, income, and debt-to-income ratio. Most require a credit score of 650 or higher, though some will work with scores as low as 600. You will also need to show current income — through recent pay stubs, tax returns, or bank statements — and proof that you are a U.S. citizen or permanent resident.
Key Takeaways
- Refinancing replaces your current student loans with a new private loan, usually to lower your interest rate or monthly payment.
- You lose federal protections like income-driven repayment plans, loan forgiveness programs, and deferment options when you refinance federal loans.
- Lenders typically require a credit score of 650 or higher, current income verification, and a debt-to-income ratio under 50 percent.
- The refinancing process takes one to three weeks from application to funding, and you can refinance again later if your circumstances change.
- Refinancing makes sense if your credit has improved since you took out the original loan, or if you want to shorten the repayment term and pay less interest overall.
When Refinancing Saves You Money
Refinancing saves money when the new interest rate is lower than your current rate. If you borrowed at 6.5 percent and can refinance at 5.2 percent, you pay less over the life of the loan — even after accounting for any fees the new lender charges.
The math depends on your loan balance, the rate difference, and how long you plan to keep the loan. A $50,000 loan refinanced from 6.5 percent to 5.2 percent over 10 years saves roughly $6,000 in interest. The same refinance over 5 years saves less in total dollars but costs you less per month.
Your credit score is the biggest factor in the rate you receive. If your score has risen since you took out the original loan — because you paid bills on time, reduced credit card balances, or resolved past problems — you will likely may have access to for a lower rate. Lenders also offer better rates to borrowers with higher incomes or lower debt-to-income ratios.
What You Lose When You Refinance Federal Loans
Federal student loans come with protections that private loans do not have. When you refinance a federal loan into a private one, you give up all of them. This is the most important trade-off to understand before you proceed.
Income-driven repayment plans allow you to cap your monthly payment at a percentage of your discretionary income — often 10 to 20 percent. If your income drops or you face hardship, you can request a lower payment or temporary pause. Private lenders do not offer this. Your payment stays the same regardless of your financial situation.
Public Service Loan Forgiveness (PSLF) erases remaining federal loan balances after 120 may have access to payments if you work for a government agency or nonprofit. Refinancing into a private loan makes you ineligible forever — you cannot go back. The same applies to other federal forgiveness programs tied to income or employment.
Deferment and forbearance let you pause federal loan payments during hardship, unemployment, or economic downturn without defaulting. Interest may or may not accrue depending on the type. Private lenders rarely offer this, and when they do, interest continues to accrue and the pause is temporary.
If you are pursuing PSLF, work in a field with loan forgiveness programs, or think your income may drop significantly, refinancing federal loans is usually not the right choice.
How to Compare Refinancing Offers
Most lenders let you check your rate without a hard credit inquiry — this is called a soft pull or rate quote. You provide basic information and see what rate you might receive. This does not affect your credit score and takes a few minutes.
Once you have quotes from multiple lenders, compare them on these points: the interest rate (fixed or variable), the loan term (5, 7, 10, or 15 years), the monthly payment, any origination or application fees, and whether the lender offers a co-signer release option. Some lenders charge 0.5 to 1 percent of the loan amount as an origination fee; others charge nothing.
A lower rate matters only if the monthly payment fits your budget. A 10-year loan at 4.5 percent costs more per month than a 15-year loan at the same rate, but you pay less interest overall. A 5-year loan costs the most per month but the least in total interest. Choose the term that balances your monthly cash flow with how much interest you want to pay.
Variable-rate loans start lower than fixed-rate loans but can increase over time, usually capped at 8 to 9 percent. If you plan to refinance again in a few years, a variable rate might save money. If you want predictability, choose fixed.
The Refinancing Application and Timeline
After you select a lender and decide on terms, you submit a formal application. You will need to provide your Social Security number (which triggers a hard credit pull), recent pay stubs or tax returns, proof of citizenship or permanent residency, and details about your current loans — the lender name, account number, and outstanding balance.
The lender verifies your income and pulls your credit report. This usually takes three to five business days. If the lender approves you, they send a loan agreement spelling out the exact rate, term, and monthly payment. You sign and return it electronically or by mail.
Once you sign, the lender contacts your current loan servicer and requests payoff amounts for each loan you are refinancing. They then send the payoff funds directly to your current servicer, closing those loans. This final step takes five to ten business days. Your new loan begins on the date the old ones are paid off.
From application to funding, the entire process usually takes one to three weeks. During this time, continue making payments on your current loans — do not assume they are closed until you receive confirmation from your servicer.
Private Loans and Parent PLUS Loans
Refinancing private student loans is straightforward: you are simply replacing one private loan with another. You do not lose any federal protections because there were none to begin with. The same credit and income requirements apply.
Parent PLUS loans are federal loans taken out by parents to pay for their child's education. They can be refinanced into private loans, but this also means losing federal protections like income-driven repayment and deferment. Parent PLUS loans typically carry higher interest rates than other federal loans, so refinancing often makes financial sense — but only if the parent's credit score and income support a lower private rate.
Some lenders offer co-signer release after a set number of on-time payments, usually 24 to 36 months. This removes the co-signer from the loan, and the primary borrower becomes solely responsible. If you refinanced with a co-signer, ask about this option upfront.
When Refinancing Does Not Make Sense
Do not refinance if you are pursuing loan forgiveness through PSLF or another federal program. Refinancing disqualifies you permanently, and the forgiveness benefit is usually worth more than the interest savings from a lower rate.
Do not refinance if your credit score is below 650 or your debt-to-income ratio exceeds 50 percent. You will either be denied or offered a rate higher than what you currently have. Wait until your credit improves or your income rises.
Do not refinance if you cannot afford a higher monthly payment. Some borrowers refinance to a shorter term (5 years instead of 10) to save interest, but this raises the monthly cost. If your budget is tight, a longer term keeps payments manageable — even if you pay more interest overall.
Do not refinance variable-rate loans if interest rates are rising and you cannot absorb a payment increase. Fixed-rate refinancing protects you from future rate hikes.
Frequently Asked Questions
Can I refinance my student loans more than once?
Yes. You can refinance again if your credit improves, your income rises, or interest rates drop. There is no limit to how many times you can refinance. Each refinance triggers a new hard credit pull and requires a new application, so space them out — multiple applications in a short time can lower your credit score.
What happens to my old loan after I refinance?
Your old loan is paid off and closed by the new lender. You will no longer owe the original servicer. Make sure you receive written confirmation from your original servicer that the loan is closed before you assume it is gone. Keep records of the payoff for your tax and financial files.
Can I refinance if I am in default or behind on payments?
Most lenders will not refinance loans in default or with recent late payments. You typically need to be current on all payments for at least six months before applying. If you are behind, contact your servicer about a payment plan or forbearance first, then refinance once you are current.
Do I have to refinance all my loans at once?
No. You can refinance some loans and leave others alone. Many borrowers refinance private loans while keeping federal loans separate, or refinance only the loans with the highest interest rates. Each refinance is a separate transaction with its own terms.
What if my income is irregular or I am self-employed?
Most lenders accept self-employed borrowers but require two years of tax returns to verify income. Some use an average of the past two years; others use the most recent year. Ask the lender what documentation they need before you apply. Having a co-signer with stable W-2 income can improve your chances of approval.
