Finding the lowest student loan refinance rates can reduce your interest costs, lower your monthly student loan payment, or help you repay your debt faster. But the lowest advertised rate is not necessarily the best loan for you.
As of October 2026, some private refinancing lenders advertise fixed rates below 5%, while rates for longer repayment terms and less-qualified borrowers can be considerably higher. Your actual offer depends on factors such as credit history, income, debt-to-income ratio, loan balance, repayment term and whether you use a co-signer.
The most important rule is simple: compare the total cost of each refinance offer—not just its headline APR.
Student Loan Refinance Rates at a Glance
Rates change frequently, so borrowers should check lenders directly before applying. Current advertised examples include:
| Lender | Example starting fixed APR | Typical refinance terms/features |
|---|---|---|
| SoFi | 3.99% APR | 5–20 years; fixed and variable options |
| ELFI | 4.29% APR | 5–20 years; fixed and variable options |
| RISLA | 3.99% APR in its refinance materials | Fixed-rate refinancing; nonprofit lender |
| Earnest | Rates vary by borrower and term | Flexible repayment options |
| Citizens | Personalized rates | Fixed and variable refinance loans |
These are advertised starting rates, not guaranteed offers. SoFi’s current published refinance table, for example, shows fixed APRs ranging from 3.99% to 10.99% depending on term and borrower circumstances, while ELFI currently lists fixed rates starting at 4.29%.
What Is Student Loan Refinancing?
Student loan refinancing replaces one or more existing student loans with a new private student loan.
The new lender pays off your existing loans, and you then make payments to the new lender under the new interest rate and repayment term.
Refinancing can potentially:
- Lower your interest rate
- Reduce your monthly payment
- Reduce total interest charges
- Change a variable rate to a fixed rate
- Change a fixed rate to a variable rate
- Combine several loans into one payment
- Shorten your repayment term
- Release a co-signer, if the new lender permits it
Private student loan refinancing is generally most attractive to borrowers whose credit and income have improved since they originally borrowed.
Who Gets the Lowest Student Loan Refinance Rates?
The lowest rates are generally reserved for borrowers with strong financial profiles.
Lenders commonly evaluate:
- Credit score and credit history
- Income and employment
- Debt-to-income ratio
- Existing student loan balance
- Degree and educational background
- Repayment history
- Loan term
- Whether a qualified co-signer is involved
A credit score around 670 or higher is commonly viewed as a useful benchmark for refinancing eligibility, although individual lenders can have different requirements and some may accept borrowers with lower scores. A higher score can improve both approval odds and pricing.
A strong co-signer may also help a borrower qualify for better terms. However, the co-signer becomes legally responsible for repayment if the primary borrower fails to pay.
Fixed vs. Variable Student Loan Refinance Rates
Choosing between a fixed and variable interest rate can be just as important as finding a low APR.
Fixed-rate refinancing
A fixed interest rate remains unchanged throughout the loan term.
Best for: borrowers who prioritize predictable payments and protection against future rate increases.
Variable-rate refinancing
A variable interest rate can change according to its underlying market index.
Best for: borrowers who understand rate risk and expect to repay the loan relatively quickly.
A variable loan can initially carry a lower rate, but the payment can increase if the underlying index rises. For a long repayment period, that uncertainty can outweigh the initial savings.
For most borrowers who want predictable student loan repayment, a competitive fixed rate is easier to budget around.
Does Refinancing Student Loans Save Money?
It can, but not automatically.
Suppose you have $50,000 remaining at 7.5% with 10 years left. Refinancing to a lower fixed rate while keeping roughly the same repayment period could substantially reduce interest costs.
However, extending the loan from 10 years to 20 years can reduce your monthly payment while increasing the total amount of interest you pay.
That is why borrowers should compare three numbers:
- New monthly payment
- Total interest
- Total amount repaid
A student loan refinance calculator can make this comparison easier.
A useful rule
If refinancing gives you a lower rate without unnecessarily extending the repayment period, the potential savings are generally easier to identify.
When Should You Refinance Student Loans?
Refinancing may make sense when:
- Your credit score has improved.
- Your income is stable or has increased.
- You have a reliable repayment history.
- Your existing private loan has a relatively high interest rate.
- You can qualify for a lower fixed rate.
- You want to pay off your debt faster.
- You have enough financial stability to give up federal protections, if applicable.
You may want to wait if your credit is weak, your income is unstable, or your current federal loans provide valuable repayment or forgiveness benefits.
Can You Refinance Federal Student Loans?
Yes, but federal student loans can only be refinanced into a private loan.
There is an important distinction between refinancing and federal consolidation.
A private lender can replace your federal loans with a private refinance loan. But doing so generally means permanently leaving the federal student loan system.
Federal Student Aid warns that refinancing federal loans into private loans can mean losing federal benefits such as income-based repayment options, qualifying forgiveness programs, deferment and forbearance protections, and certain discharge provisions.
Therefore, a lower private interest rate is not automatically a better financial decision.
What Are the Risks of Refinancing Federal Loans?
The biggest risk is losing federal protections.
Depending on your circumstances, refinancing could mean losing access to:
- Income-driven repayment
- Federal deferment and forbearance
- Public Service Loan Forgiveness
- Certain teacher forgiveness programs
- Federal discharge protections
- Other federal repayment options
This is particularly important if you work for a government or qualifying nonprofit employer, expect to use loan forgiveness, have uncertain income, or may need income-based payments in the future.
The Consumer Financial Protection Bureau has specifically warned about the loss of federal protections when federal loans are refinanced through private lenders.
Bottom line: carefully compare the value of your federal benefits against the interest savings before refinancing federal debt.
Can You Refinance Private Student Loans?
Yes. Private student loans are usually the simplest candidates for refinancing.
Because private loans do not provide the same federal benefits, borrowers generally have fewer government protections to give up.
If your private student loan has a high interest rate and your credit or income has improved, refinancing may allow you to qualify for a lower rate.
You can also potentially refinance several private loans into a single new loan.
Refinancing vs. Federal Student Loan Consolidation
These terms are often confused.
Federal consolidation combines eligible federal loans into a new federal Direct Consolidation Loan. It does not work like private refinancing and generally does not produce a dramatically lower interest rate simply because you consolidated.
Private refinancing replaces existing debt with a new private loan whose rate is based largely on your creditworthiness and other underwriting factors.
Federal consolidation can preserve access to federal protections, whereas refinancing federal loans with a private lender generally does not.
Before choosing either option, compare your current loan terms, repayment plan, forgiveness eligibility, interest rate and remaining term.
How to Refinance Student Loans: 7 Steps
1. Check your current loans
Record each loan’s:
- Balance
- Interest rate
- Fixed or variable status
- Remaining term
- Monthly payment
- Federal or private status
2. Check your credit
Review your credit reports for errors and determine whether your score has improved since you originally borrowed.
3. Compare several lenders
Do not assume the first lender offering a low rate is the cheapest option.
Compare at least several reputable student loan refinancing companies.
4. Prequalify where possible
Many lenders allow borrowers to view estimated rates through a soft credit inquiry. This can help you compare potential offers before committing to a full application.
5. Compare repayment terms
A 5-year refinance may produce a higher monthly payment but lower total interest. A 20-year term may provide payment relief but increase lifetime interest.
6. Read the fine print
Check:
- APR
- Fixed or variable rate
- Fees
- Autopay discounts
- Repayment term
- Forbearance provisions
- Co-signer rules
- Co-signer release
- Death or disability discharge policies
- Minimum loan amount
7. Choose the loan based on total cost
The lowest monthly payment is not necessarily the cheapest loan.
How to Refinance Student Loans With Bad Credit
Refinancing with bad credit is possible with some lenders, but the lowest advertised rates are generally harder to obtain.
Consider:
- Adding a qualified co-signer
- Paying down credit card balances
- Correcting credit-report errors
- Improving payment history
- Lowering your debt-to-income ratio
- Waiting until your income or credit profile improves
A co-signer can potentially improve approval odds and pricing, but they also take on repayment responsibility.
If your existing private lender allows co-signer release, that may be another option worth exploring before refinancing.
What About a 20-Year Student Loan Refinance?
A 20-year student loan refinance can significantly lower the monthly payment because the balance is spread across more payments.
However, the tradeoff is usually higher total interest.
A long repayment term can make sense if your immediate priority is cash-flow relief and the new rate is substantially lower. But if you can afford the payment, a shorter term will generally reduce the time you remain in debt and the amount of interest paid.
Parent PLUS Loan Refinancing
Parent PLUS loans can be refinanced with private lenders, potentially at a lower interest rate.
This can be particularly attractive for parents with strong credit who have relatively high-rate PLUS debt.
However, federal Parent PLUS loans have federal protections that can be lost when refinanced privately.
Before refinancing, compare the potential interest savings with the value of federal repayment and forgiveness options available to your specific situation.
SoFi Student Loan Refinance
SoFi is one of the better-known student loan refinancing companies. Its current published rates show fixed refinance APRs starting at 3.99%, with available terms ranging from five to 20 years. Its variable rates start higher in the current published table.
SoFi also offers a rate-check process that does not initially require a hard credit inquiry.
Borrowers should remember that SoFi refinance loans are private loans. Refinancing federal debt into a SoFi loan means giving up federal student loan benefits.
Earnest Student Loan Refinance
Earnest is another major private student loan lender frequently considered by borrowers comparing refinance offers.
Its refinance products have historically emphasized flexible repayment options and personalized underwriting.
As with any lender, borrowers should check Earnest’s current rate range directly before applying because advertised rates can change and the rate you receive depends on your financial profile.
Student Loan Refinance Calculator: How to Use One
A refinance calculator should compare your existing loan with the proposed refinance loan.
Enter:
- Current balance
- Current interest rate
- Remaining repayment period
- Current monthly payment
- New interest rate
- New repayment term
Then compare the estimated monthly payment and total interest.
For example, don’t automatically choose a 20-year loan simply because its monthly payment is lower. Calculate how much additional interest the longer term could create.
How We Evaluate Student Loan Refinancing Companies
A useful comparison should consider more than the lowest advertised APR.
Key factors include:
- Lowest available fixed APR
- Variable-rate options
- Available repayment terms
- Minimum and maximum loan amounts
- Credit and income requirements
- Co-signer policies
- Co-signer release
- Fees and prepayment penalties
- Borrower protections
- Parent PLUS refinancing
- Prequalification availability
- Customer support
The best student loan refinance lender is the one that offers the best combination of rate, term and protections for your circumstances, not necessarily the company with the lowest advertised starting number.
Pros and Cons of Student Loan Refinancing
Advantages
- Potentially lower interest rate
- Potential student loan savings
- Lower monthly payment
- Faster debt payoff
- One payment instead of several
- Potential co-signer release
- Fixed-rate option for borrowers with variable debt
Disadvantages
- Federal benefits may be lost
- A longer term can increase total interest
- Variable rates can rise
- Approval is not guaranteed
- The lowest advertised rate may be difficult to qualify for

The Bottom Line
The lowest student loan refinance rates can make a meaningful difference, particularly for borrowers with strong credit, stable income and high-rate private student debt.
But rate alone should never determine the decision.
For private loans, compare multiple lenders and look for a lower APR without unnecessarily extending your repayment term. For federal loans, first determine whether you could benefit from federal repayment programs, forgiveness or other protections.
The smartest refinancing strategy is the one that lowers your borrowing cost without sacrificing benefits that are worth more than the interest savings.
