How to refinance student loans is an increasingly important question for U.S. borrowers as private refinance rates, federal repayment rules, and borrowing costs continue to change in 2026. The Federal Reserve raised its benchmark rate by 0.25 percentage point on September 16, while private student-loan refinancing offers remain highly dependent on credit, income, loan term and lender criteria.
Refinancing replaces one or more existing student loans with a new private student loan. The new loan can have a different interest rate, repayment period and monthly payment. Borrowers generally seek refinancing to reduce interest costs, simplify multiple loans or change their repayment timeline.
However, refinancing federal student loans requires particular caution. A private refinance permanently moves the debt outside the federal student-loan system. That can eliminate federal repayment options, forgiveness programs and other borrower protections.
What Student Loan Refinancing Means
Student loan refinancing involves applying for a new loan from a private lender. If approved, the new lender uses the proceeds to pay off the existing student loans. The borrower then makes payments on the new loan.
The new interest rate can be fixed or variable, depending on the lender and product. A fixed rate remains unchanged during repayment. A variable rate can move over time based on the index and terms specified in the loan agreement.
The rate a borrower receives depends on factors such as credit history, income, debt obligations, loan amount, repayment term and whether a creditworthy co-signer is included.
Refinancing is different from federal Direct Consolidation. Federal consolidation keeps eligible federal loans inside the federal system and uses a weighted-average interest rate, rounded up to the nearest one-eighth of a percentage point. Private refinancing creates a new private loan instead.
Why Borrowers Are Considering Refinancing in 2026
Current borrowing conditions make rate comparisons particularly important. On September 16, the Federal Reserve increased its benchmark interest rate by 0.25 percentage point. That change can influence broader borrowing costs, although private student-loan refinance rates do not move in lockstep with the federal-funds rate.
Private refinance offers vary considerably. For example, NerdWallet’s September 2026 rate information lists advertised fixed-rate ranges of 3.99% to 10.99% for SoFi, 3.94% to 9.99% for Earnest, 4.29% to 8.44% for ELFI and 4.39% to 9.24% for LendKey. Actual offers depend on individual borrower qualifications and can change.
CNBC Select also reports refinance offers beginning around 3.99% fixed for some highly qualified borrowers, while emphasizing that rates depend on creditworthiness, income, term and other factors.
These advertised starting rates are not guaranteed rates for every applicant. Borrowers should compare personalized offers rather than choosing a lender based only on its lowest advertised figure.
Check Your Existing Student Loans First
Before submitting an application, identify every student loan you currently have.
Federal borrowers can log into StudentAid.gov to review loan types, balances, servicers, repayment plans and other federal-loan information. Federal Student Aid specifically recommends checking the Dashboard when determining loan type and repayment-plan eligibility.
Private loans should be reviewed through the current lender or servicer. Record each loan’s:
- Current principal balance
- Interest rate
- Fixed or variable rate status
- Monthly payment
- Remaining repayment period
- Co-signer information
- Available hardship provisions
- Potential prepayment penalties or fees
This information gives you a baseline for comparing a refinance offer.
Determine Whether Refinancing Federal Loans Could Affect You
Federal student loans carry protections that private refinance loans generally do not provide.
The Consumer Financial Protection Bureau warns that refinancing federal loans into private loans can cause borrowers to lose access to federal income-driven repayment programs, federal deferment and forbearance options, and federal forgiveness programs.
That issue is especially important in 2026 because federal repayment rules have changed.
The Saving on a Valuable Education, or SAVE, Plan is no longer available after a federal court order ended the program. Federal Student Aid says borrowers affected by the change must select another repayment plan and should review their options through StudentAid.gov.
New federal repayment rules also introduced the Repayment Assistance Plan and Tiered Standard Plan beginning July 1, 2026. Eligibility depends on loan type and when the loans were disbursed.
Because federal repayment options are changing, borrowers should review their federal alternatives before transferring federal debt to a private lender.
Understand Current Federal Student Loan Rates
Federal student-loan rates are fixed for the life of each loan and vary according to the year the loan was first disbursed.
For loans first disbursed from July 1, 2026, through June 30, 2027, the rates are:
| Federal loan type | Fixed interest rate |
|---|---|
| Direct Subsidized and Direct Unsubsidized Loans for undergraduates | 6.52% |
| Direct Unsubsidized Loans for graduate and professional students | 8.07% |
| Direct PLUS Loans for parents and graduate/professional students | 9.07% |
These rates apply to the specified 2026–27 federal loan cohort. Earlier federal loans can carry different rates.
A borrower should therefore compare the actual rate on an existing loan with the personalized refinance rate available today. Simply comparing a refinance lender’s advertised starting rate with the current federal rate may produce a misleading picture.
Review Your Credit and Income
Private lenders use their own underwriting standards. Strong credit and dependable income can improve a borrower’s ability to qualify for competitive terms.
Before applying, review your credit reports for inaccurate information. Paying bills on time and reducing outstanding revolving debt can also strengthen an application over time.
Some borrowers use a co-signer when they cannot qualify independently or want to seek better terms. A co-signer becomes legally responsible for the loan if the primary borrower does not meet the payment obligations.
Some refinance lenders offer co-signer release after specified requirements are met. The exact conditions vary, so borrowers should read the lender’s agreement carefully.
Compare Multiple Refinance Offers
Do not assume your existing bank will provide the lowest available refinance rate.
NerdWallet’s September 2026 research notes that many large banks do not offer student-loan refinancing, while online lenders and marketplace platforms have become significant sources of refinance options.
Many lenders allow borrowers to prequalify before submitting a full application. Prequalification can provide an estimated rate after a soft credit inquiry, although the formal application generally involves a hard credit inquiry.
When comparing offers, look beyond the headline interest rate.
Check:
- Annual percentage rate
- Fixed versus variable rate
- Loan term
- Monthly payment
- Total interest
- Origination fees
- Late-payment fees
- Available hardship options
- Deferment or forbearance provisions
- Co-signer release rules
- Death or disability discharge provisions
A lower monthly payment does not necessarily mean a cheaper loan. Extending the repayment period can reduce the monthly bill while increasing total interest paid.
Choose the Right Repayment Term
The repayment term can dramatically affect the cost of refinancing.
A shorter term generally produces larger monthly payments but allows the borrower to repay principal faster. A longer term can reduce monthly payments but may increase the total interest paid over the life of the loan.
For example, a borrower should compare the total repayment cost of a five-year refinance with a 10- or 15-year option instead of looking only at the monthly payment.
The right comparison is the complete cost of the new loan against the remaining cost of the existing loans.
Decide Between Fixed and Variable Rates
Fixed-rate refinancing provides predictable payments because the interest rate does not change.
Variable-rate refinancing may initially offer a lower rate, but the rate can increase or decrease according to the loan’s contractual formula. That means a borrower needs to understand the index, margin, adjustment frequency and maximum rate before accepting a variable loan.
For borrowers who prioritize predictable payments, the stability of a fixed rate may be an important consideration. The specific financial tradeoff depends on the offer and the borrower’s circumstances.
Submit the Full Application
Once you have compared offers, select the loan that matches your financial objectives and submit the formal application.
The lender may request documentation such as:
- Government-issued identification
- Proof of income
- Employment information
- Existing loan statements
- Loan payoff amounts
- Housing information
- Details about other debts
The lender will review your application and credit history. If approved, carefully review the final disclosure before signing.
Do not stop making payments on your existing loans until the refinance lender confirms that the original balances have been paid off and the transition is complete.
Watch the Loan Transfer Carefully
After refinancing, confirm that each old student loan shows a zero balance or has otherwise been properly paid off.
Keep copies of the final statements, refinance documents and payoff confirmations. Also verify the first payment date and the amount owed under the new loan.
A borrower should update automatic payments and financial records after the new account becomes active.
When Refinancing Private Student Loans May Be Simpler
Private student loans do not carry the same federal benefits as federal student loans. As a result, borrowers with private debt may have fewer federal protections to give up when refinancing.
The CFPB says refinancing private student loans can potentially reduce the interest rate, lower monthly payments or release a co-signer, depending on the new lender’s terms. Extending the repayment period, however, can increase the total cost.
For private borrowers, the central comparison is usually the existing loan against the new private loan.
A borrower should still examine the new lender’s hardship policies and other contractual protections before signing.
Can You Refinance Federal and Private Loans Together?
Some private lenders allow borrowers to refinance a combination of federal and private student loans into one private loan.
That can create one monthly payment, but the federal portion becomes private debt after refinancing.
The CFPB specifically warns that borrowers can lose federal repayment programs, forgiveness opportunities and other federal protections when federal loans are moved into a private refinance.
For that reason, combining federal and private loans requires careful comparison rather than focusing solely on convenience.
A 2026 Refinance Checklist
Before accepting an offer, confirm these points:
- You know whether each existing loan is federal or private.
- You have checked your current interest rates.
- You have reviewed your federal repayment options if applicable.
- You have compared several private refinance offers.
- You know whether the new rate is fixed or variable.
- You understand the repayment term.
- You have calculated total repayment costs.
- You understand all fees.
- You have reviewed co-signer provisions.
- You have confirmed the lender’s hardship and discharge policies.
This checklist can help prevent a lower monthly payment from masking a higher long-term cost.
FAQs About Student Loan Refinancing
Is it possible to refinance federal student loans?
Yes. Federal student loans can be refinanced through a private lender. The resulting loan is private, however, and the borrower generally loses federal benefits and protections attached to the original loans.
Can federal student loans be refinanced through StudentAid.gov?
No. Federal Student Aid explains that federal loans cannot be refinanced within the federal student-aid system. Eligible federal loans can instead be combined through a Direct Consolidation Loan, which is different from private refinancing.
Does refinancing lower the interest rate?
It can, but there is no guarantee. Private lenders determine rates based on factors including creditworthiness, income, loan characteristics and repayment term. Advertised starting rates generally apply to borrowers who meet the lender’s strongest qualification criteria.
Does refinancing lower the monthly payment?
It can. A lower interest rate or longer repayment term may reduce the monthly payment. However, extending the term can increase the total interest paid.
Can you refinance student loans more than once?
Yes. Borrowers can refinance again if they qualify for another private loan. Before doing so, compare the new rate and total repayment cost with the current loan.
Will refinancing hurt your credit score?
A formal application can result in a hard credit inquiry, which may temporarily affect a credit score. Prequalification may use a soft inquiry, depending on the lender.
Can you refinance with a co-signer?
Many private lenders permit co-signers. A creditworthy co-signer may help some borrowers qualify or obtain different terms. Some lenders also provide a pathway for co-signer release after specific requirements are met.
Should you refinance a federal student loan if you qualify for a lower rate?
The interest-rate difference is only one part of the decision. Federal borrowers should also consider repayment-plan eligibility, forgiveness programs, deferment, forbearance and other federal protections before converting the debt to private financing.
What is the first step when deciding how to refinance student loans?
Start by listing every loan, its balance, interest rate, loan type and remaining term. Then compare personalized private refinance offers with the cost and protections attached to your current loans.
Bottom Line
Student loan refinancing can change the interest rate, payment amount and repayment period on existing education debt. In 2026, borrowers also need to account for changing federal repayment rules and the current private lending environment.
The most important comparison is not simply the lowest advertised rate. Borrowers should evaluate the complete loan cost, repayment term, rate structure and protections they would gain or give up.
