Refinancing replaces your existing student loans with one new private loan at a new rate. When that rate is meaningfully lower, the savings are real: dropping a $40,000 balance from 7% to 5% over ten years cuts about $4,821 in interest and lowers the monthly payment by roughly $40. But there's a catch that the savings math hides — refinancing federal loans into a private loan permanently surrenders income-driven repayment, forgiveness, and federal hardship protections. The right answer depends as much on what kind of loans you have as on the rate.
So this isn't only a math question. Here are the 2026 numbers, and the trade-off that matters more than the rate.
1. The Short Answer
Refinance if — and only if — two things are true: you can get a rate clearly below what you pay now, and you don't need the protections that come with federal loans. For borrowers with private student loans, the decision is mostly just the math. For borrowers with federal loans, the math is the easy part and the protections are the hard part.
Get those two questions right and refinancing is a clean win or a clear no. Get them wrong — refinancing federal loans you later need flexibility on — and the lower rate can cost you far more than it saved.
2. What Rates Look Like in 2026
As of June 2026, federal student loan rates sit around 6.39% for undergraduate loans first disbursed in the 2025–26 year, and they're set to tick up to about 6.52% for loans disbursed starting July 1, 2026. Existing federal loans keep their original fixed rate.
On the refinancing side, lenders are advertising fixed rates as low as roughly 3.6% for the strongest borrowers, with most offers landing in the 4%–14% range depending on credit, income, and term. Recent averages have run near 5.3% on the low end. Translation: if your loans are above about 6.5% and your credit is solid, a refinance near 5% is realistic — and that gap is where the savings live.
3. A Real $40,000 Example
Take $40,000 in loans at 7% on a standard ten-year (120-month) payoff, refinanced to 5% over the same ten years.
| Loan | Rate | Monthly | Total Interest | Total Paid |
|---|---|---|---|---|
| Current loans | 7% | $464 | $15,732 | $55,732 |
| Refinanced | 5% | $424 | $10,911 | $50,911 |
Two points of rate is worth about $4,821 over the life of the loan, plus a payment that's roughly $40 lighter every month. The bigger your balance and the wider the rate gap, the bigger the prize.
Interest saved by refinancing $40,000 from 7% to 5% over ten years. Real money — but only worth taking if these are private loans, or you're certain you won't need federal protections.
4. The Federal-Loan Warning
This is the part the rate comparison won't tell you. When you refinance a federal loan, it becomes a private loan — and you permanently give up everything the federal system offers:
Income-driven repayment that caps your payment as a share of income. Public Service Loan Forgiveness and other forgiveness paths. Generous deferment and forbearance if you lose your job. And death or disability discharge that cancels the debt in a crisis. A private lender owes you none of these.
That's why the savings math can be a trap for federal borrowers. If there's any real chance you'll need flexibility — unstable income, a public-service career, or a forgiveness path you're pursuing — the safer move is to keep your federal loans and attack them with extra payments instead.
Not sure refinancing is your best move?
The Student Loan Planner Mini Guide walks you through refinance vs. keep-and-accelerate so you weigh the rate against what you'd give up.
5. Who Should and Shouldn't Refinance
Refinancing tends to make sense if you hold high-rate private student loans, or you have a stable income and strong credit, you're confident you'll repay in full, and you have no interest in forgiveness or income-driven plans. For you, a lower rate is close to free money.
Refinancing is usually a mistake if your loans are federal and your income is variable, you work toward Public Service Loan Forgiveness, you might need to pause payments, or your credit only qualifies you for a rate near what you already pay. In those cases, keep the federal protections and lower your cost another way.
6. Run Your Own Numbers: Use the Planner
Start with your real loans. Put your balances, rates, and term into the free student loan planner to see your payoff timeline and total interest, then compare a refinance offer against it. If you decide to keep your loans, student loan extra payments shows how to cut years off without giving up a thing, and how long it takes to pay off student loans sets the baseline. For the bigger picture, pay off student loans early or invest weighs the alternative.
FAQ: Refinancing Student Loans
Should you refinance your student loans in 2026?
Refinance only if you can get a clearly lower rate and you don't need federal protections. As of June 2026, strong-credit borrowers can find refinance rates around 5% or lower, while federal undergraduate loans carry about 6.39%. Refinancing $40,000 from 7% to 5% over 10 years saves roughly $4,821 in interest. But refinancing federal loans into a private loan permanently gives up income-driven repayment and forgiveness — so it makes the most sense for private loans, or for high earners with secure income who won't use those federal benefits.
What rate do you need to make refinancing worth it?
Your new rate should be meaningfully lower than your current one — usually at least about one percentage point — for the savings to outweigh the hassle. On a $40,000 balance, dropping from 7% to 5% saves about $4,821 over ten years. A smaller gap saves less and may not be worth giving up federal benefits. Always compare the new APR, including any fees, to your current weighted-average rate.
Should you refinance federal student loans?
Be very careful. Refinancing federal loans converts them to a private loan and permanently forfeits federal benefits: income-driven repayment plans, Public Service Loan Forgiveness, generous deferment and forbearance, and death or disability discharge. If there's any chance you'll need those — unstable income, public-service career, or pursuing forgiveness — keep your federal loans. Refinancing federal debt usually only makes sense for high earners with stable jobs who are confident they'll repay in full.
Does refinancing student loans hurt your credit?
Only slightly and briefly. The application creates one hard inquiry that can dip your score a few points, and the new loan resets that account's age. Most lenders let you check your rate first with a soft pull that doesn't affect your score, so you can shop offers safely. Making on-time payments on the new loan builds your credit back quickly.
Can you refinance student loans more than once?
Yes. There's no limit on how many times you can refinance, and there are typically no origination fees on student loan refinancing, so it can make sense to refinance again if rates drop or your credit improves. Just remember each refinance is a new private loan — once you've left the federal system, you can't get those protections back.
What credit score do you need to refinance student loans?
Lenders generally look for a score in the high 600s or above, plus steady income and a manageable debt-to-income ratio. The lowest advertised rates go to borrowers with excellent credit, often in the 700s or higher. If your credit is fair, you may still qualify but at a higher rate — and if that rate isn't clearly below your current one, refinancing won't save you money. A co-signer can sometimes secure a better rate.
