Refinancing is not a product. It is a swap. You hand a lender your balance, they hand you a new rate, and everything attached to the old loan goes with it.
That makes the question narrower than it looks. What matters is not the lowest advertised rate on a lender’s homepage. It is the gap between what you pay now, what you would pay after the swap, and what the old loan gave you for free. This page shows all three using the rates the government published for 2026–27, the auto-pay discount that changed the math on July 1, and full amortization on every figure. DollarVisor takes no payment for placement, so no lender bought its way into anything below.
A short video overview first.
1. What Are Student Loan Refinancing Rates in 2026?
Quick Answer: Student loan refinancing rates are set per borrower, not per product, so lenders publish a range and you get one number inside it. Like every credit-priced product in our guide to loan types, the quote depends on your file, not the advertisement.
Every advertised refinancing rate is a floor, reserved for the strongest applicant a lender will accept: a high earner, long credit history, shortest term, variable rate, auto-pay on. Almost nobody is all five.
Six things move your quote inside the range:
- Credit score. The largest lever. Files in the 780s and the 660s are quoted points apart on identical balances.
- Income and debt-to-income ratio. Lenders want to see the payment fit comfortably, not barely.
- Term length. A 5-year payoff is priced below a 20-year one, because the money is at risk for less time.
- Fixed or variable. Variable quotes usually start lower and can reset upward; fixed quotes lock for the life of the loan.
- A cosigner. Adding a strong cosigner is often worth more than any shopping you can do alone.
- Degree and field. Some lenders price a completed professional degree differently from an unfinished one.
Companies cannot pay for placement in our rankings, which is why this page leads with the government’s published numbers rather than a lender’s floor. That rate is the one figure every borrower can verify before filing anything.

2. What Rate Are You Actually Giving Up?
Quick Answer: Federal loans first disbursed in 2026–27 carry 6.52% for undergraduates, 8.07% for graduate students, and 9.07% for PLUS borrowers. A new 1% auto-pay reduction takes a point off each through June 2028, and that is the hurdle any refinance offer must clear.
Most comparisons of student loan refinancing rates stop at the sticker rate on your federal loan. That is now out of date. On June 18, 2026, the Department of Education announced that borrowers on auto pay get a 1% interest rate reduction from July 1, up from the usual 0.25%, running through June 30, 2028. Existing auto-pay users get it automatically; everyone else must enroll by September 30, 2026.
| Loan type | Published rate | Effective on auto pay |
|---|---|---|
| Subsidized and unsubsidized, undergraduate | 6.52% | 5.52% |
| Unsubsidized, graduate and professional | 8.07% | 7.07% |
| PLUS, parent and graduate | 9.07% | 8.07% |
Source: Federal Student Aid announcement GENERAL-26-33 and the Department of Education auto-pay announcement, June 2026. All three rates build on a 10-year Treasury high yield of 4.468%.
The published rates come from Federal Student Aid’s 2026–27 rate announcement, and the discount matters more than its size suggests. Only 40% of borrowers in active repayment are enrolled in auto pay, against more than 80% before the pandemic. So most people comparing student loan refinancing rates today are measuring against a number a full point too high.
3. Why Refinancing Rates Move With the 10-Year Treasury
Quick Answer: Federal rates are set by law each May from the 10-year Treasury auction, and private lenders price off the same long-term benchmark. That is why student loan refinancing rates and mortgage refinance timing tend to turn in the same direction at the same time.
The federal formula is public: take the high yield from the final 10-year Treasury auction before June 1, then add a statutory margin by loan type. Private refinancing has no formula, but draws on the same cost of money, so the benchmark shows which way offers are drifting.
| Academic year | 10-year Treasury high yield | Undergraduate rate | PLUS rate |
|---|---|---|---|
| 2023–24 | 3.448% | 5.50% | 8.05% |
| 2024–25 | 4.483% | 6.53% | 9.08% |
| 2025–26 | 4.342% | 6.39% | 8.94% |
| 2026–27 | 4.468% | 6.52% | 9.07% |
Source: Federal Student Aid annual rate announcements DL-23-03, DL-24-03, DL-25-03 and GENERAL-26-33. Rates apply to loans first disbursed in each period.
Three near-identical benchmark readings is the story. The yield has sat between 4.34% and 4.49% since May 2024, so anyone waiting for rates to fall has been waiting through a flat market. The 2025–26 rate came in just below this year’s.
4. What Does a Lower Rate Save on $40,000?
Quick Answer: On a $40,000 balance repaid over ten years, every point of rate is worth roughly $2,400 in interest. Moving from 9.07% to 5.52% saves $8,846 in total. Run your own balance through the loan payoff calculator before you apply anywhere.
Since private quotes are personal, the honest way to show what student loan refinancing rates are worth is to hold the balance and term steady and vary only the rate. The bands below bracket the federal anchors: 5.52% is the auto-pay undergraduate hurdle, 9.07% the PLUS sticker rate.
| Rate | Monthly payment | Total interest | Interest paid |
|---|---|---|---|
| 5.52% (federal undergrad on auto pay) | $434.50 | $12,140 | |
| 6.52% (federal undergrad sticker) | $454.60 | $14,552 | |
| 7.99% | $485.10 | $18,212 | |
| 9.07% (PLUS sticker) | $508.22 | $20,986 | |
| 10.99% | $550.77 | $26,093 |
Modeled scenario. Standard amortization over 120 months on $40,000. Federal anchors from Federal Student Aid; higher bands illustrate private pricing and are not quotes.
A parent carrying $40,000 of PLUS debt at 9.07% who refinances to 6.00% saves $7,697 in interest, and gives up every federal protection on the balance.
Two things follow. Half a point off a small balance is rarely worth the paperwork. Three points off a large one usually is, if the loan being replaced is already private.
5. How the Term You Pick Changes the Real Cost
Quick Answer: Stretching the same $40,000 from 5 to 20 years cuts the payment by $482 and raises total interest from $7,523 to $34,429. It is the trap that catches people who refinance a car loan for the payment rather than the cost.
The lowest advertised refinancing rates are attached to the shortest terms. That is not a trick: short money is cheaper money. But it means the headline rate and the affordable payment sit on different rows of the rate sheet.
| Term | Monthly payment | Total interest | Interest cost |
|---|---|---|---|
| 5 years | $792.05 | $7,523 | |
| 10 years | $464.43 | $15,732 | |
| 15 years | $359.53 | $24,716 | |
| 20 years | $310.12 | $34,429 |
Modeled scenario. Standard amortization on $40,000 at a fixed 7.00%. Rate held constant to isolate term; in practice longer terms are priced higher.
Note what the 20-year row does. The borrower pays $34,429 to borrow $40,000, nearly the balance again, and the loan outlives the reasons it was taken out. If a 10-year payment is genuinely unaffordable, that is a signal to keep federal income-driven repayment, not to buy a longer private term.

6. What You Lose When You Refinance Federal Loans
Quick Answer: Refinancing federal debt privately is permanent and strips income-driven repayment, forgiveness, and death and disability discharge. Some households replace part of that lost protection with cover from the insurance types they actually need, but nothing replaces income-driven repayment.
The Consumer Financial Protection Bureau is blunt: consolidating federal loans privately means losing your rights under the federal student loan program, and the swap cannot be reversed. What goes:
- Income-driven repayment. The payment stops tracking your income and becomes a fixed bill, whatever happens to your job.
- Forgiveness programs. Public Service and teacher forgiveness end the day a private loan pays off the federal one.
- Death and disability discharge. Federal loans discharge. Many private lenders offer something similar, but as a contract term, not a right.
- Deferment and forbearance rights. Private hardship programs are discretionary and usually shorter.
- The military rate cap. Active-duty borrowers can lose the 6% Servicemembers Civil Relief Act cap.
Two 2026 changes make that list costlier than it was a year ago. The auto-pay reduction is federal-only. And the new Repayment Assistance Plan, live since July 1, sets payments at 1% to 10% of income, cuts $50 per dependent, and waives unpaid interest on on-time payments, so a federal balance no longer snowballs while you pay it.
Be careful with sales language. CFPB examiners have found lenders giving borrowers the misleading impression that refinancing would not cost them federal cancellation rights. It does.
7. Who Actually Gets the Lowest Advertised Rate?
Quick Answer: Borrowers with strong scores, steady income well above the payment, and a completed degree. Pricing tiers work much the same way as they do for personal loans by credit score, so the score band you sit in largely decides the offer.
Refinancing is underwritten on who you are now, not who you were when you enrolled. A graduate three years into a stable salary is a different applicant from the 19-year-old who signed the original note, which is why the best student loan refinancing rates go to people who no longer look like students.
What lenders weigh most heavily:
- Credit score above roughly 720. Below that, quotes climb fast, and how credit scores are built matters more than any application tactic.
- Verifiable income with room to spare. Lenders weigh the new payment against gross monthly income, not what is left after rent.
- A finished degree. Most refinance programs require a completed credential.
- Clean recent history. Late payments in the last two years outweigh an older good record.
Fall short on two of these and it is usually better to wait two quarters and fix the file than accept a rate that barely beats what you pay now.

8. How to Shop Rates Without Hurting Your Credit
Quick Answer: Set your hurdle rate first, gather soft-pull quotes from three or four lenders inside a short window, then submit one hard application. The order matters as much as the shopping, and our methodology page explains how we test rate claims.
- Turn on auto pay and write down your hurdle rate. For 2026–27 undergraduate debt that is 5.52%, for PLUS 8.07%. Any offer above it loses before you compare anything else.
- Get soft-pull quotes from at least three lenders. Pre-qualification uses a soft inquiry, which does not touch your score.
- Compare APR, not the rate. APR carries the fees, so a lower rate with an origination charge can cost more than a higher one without.
- Hold the term constant. Quotes at different terms are not comparable; price every lender at the same payoff date.
- Submit one hard application inside a two-week window. Clustered inquiries for one purpose are treated far more gently than scattered ones.
One thing to check before signing: whether the lender releases a cosigner, and after how many on-time payments. If the contract is silent, assume the cosigner stays.
9. The Verdict
Quick Answer: Refinance private student loans whenever a fixed offer beats your current rate by a point or more. Leave federal loans alone through June 2028 unless you clear the auto-pay hurdle by a wide margin and will never need income-driven repayment.
Our pick for private balances is a fixed-rate refinance on the shortest term you can comfortably pay. The math above is unambiguous: on $40,000, three and a half points of rate is worth $8,846, and no protection on a private loan justifies giving that up.
Federal balances are the opposite call this year. A 6.52% undergraduate loan on auto pay costs 5.52% through June 2028, carries income-driven repayment, and now waives unpaid interest when you pay on time. A private offer has to beat 5.52% by enough to cover everything it takes away, and for most borrowers under $50,000 of debt it does not.
The households where refinancing federal debt still makes sense are narrow: high, stable earners, large balances, no path to forgiveness, and a fixed offer well under the hurdle. If that is not you, turn on auto pay, keep the federal loan, and revisit in 2028 when the discount expires. Every rate here is checked against its published source and none of it is for sale: see the rest of the DollarVisor loans hub for the same treatment of the products around it.
10. Frequently Asked Questions
What is a good student loan refinancing rate in 2026?
Anything below the federal rate you hold now, after the auto-pay reduction. For undergraduate loans issued in 2026–27 that means beating 5.52%, for graduate loans 7.07%, for PLUS loans 8.07%. A private offer above your hurdle rate is not a good rate, however it is advertised: you would pay more for fewer protections.
Can you refinance federal student loans?
Yes, but only into a private loan. There is no federal refinancing program. A Direct Consolidation Loan combines federal loans at their weighted average rate, rounded up to the nearest eighth of a percent, so it simplifies the bill without lowering the cost. Only a private refinance cuts the rate, and it ends your federal protections permanently.
Does refinancing student loans hurt your credit score?
Briefly and mildly. Pre-qualification uses a soft inquiry with no effect. The single hard inquiry at application usually costs a few points and fades within a year, and closing the old loan shortens your average account age. Against that, a lower payment made on time every month tends to help more than the inquiry hurt.
Is a fixed or variable rate better when refinancing?
Fixed, for most borrowers. Variable quotes start lower, but the rate can reset upward for the rest of the term and most contracts carry no cap. Variable only makes sense on a short payoff you are certain to finish, five years or less, where the rate has little time to move against you.
How much do you need to save for refinancing to be worth it?
Enough to justify a permanent change. On a private balance, a rate cut of one point or more usually clears that bar. On a federal balance the threshold is far higher, because you are also buying out of income-driven repayment, forgiveness, and death and disability discharge.
