What is a good student loan interest rate? See if you're overpaying.

Student loan interest rates are constantly changing, so it’s important to check current rates to get an idea of what you should shoot for. Federal student loan interest rates, which range from 6.39% to 8.94% for the 2025-26 academic year, are generally a good benchmark.

If you’re applying for private student loans, rates can range from roughly 3% to 18%, depending on the lender. You’ll want to try and secure an interest rate on the low end of that spectrum.

Understanding how interest rates on student loans work can give you some insight into your costs and help you determine whether you’re paying too much. Here’s what you need to know.

Rates on federal student loans are standardized and fixed, meaning everyone who qualifies receives the same rate that won’t change for the life of the loan. Here’s a look at the interest rates for the 2025-26 academic year:

Direct undergraduate loans: 6.39%
Direct graduate and professional loans: 7.94%
Direct PLUS Loans (parents and grad students): 8.94%

Direct undergraduate and graduate loans don’t require a credit check, so your credit history won’t affect your eligibility or rate. Direct PLUS Loans do require a credit check, but only to verify you have no major negative items on your credit reports — your rate remains the same regardless of your credit score.

Unlike private student loan interest rates, which can fluctuate regularly, federal loan rates are adjusted once a year for new borrowers. There are a few different factors that can influence the interest rates on your student loans:

Legislation: Since 2013, Congress has calculated federal loan rates annually using the 10-year Treasury bill yield at the final Treasury auction held before June 1, plus a margin that varies based on the loan program.
Economic conditions: The 10-year Treasury yield moves with broader economic factors such as inflation and Federal Reserve policy. When inflation is high or economic uncertainty pushes Treasury yields upward, the rates for new federal loans increase. When yields fall — as they often do in periods of lower inflation or slowing economic growth — federal loan rates tend to drop as well.
Loan type: The Department of Education has three different loan programs, each with a different interest rate. In general, undergraduate loans have the lowest rates.

Based on a review of top private student loan companies, interest rates range from about 3% to 18%, with an average of 9.2% for undergraduate students and 9.51% for graduate students.

Many lenders offer both fixed and variable interest rates. While fixed rates stay the same for the life of the loan, variable rates can fluctuate as often as monthly.

Your interest rate with a private lender will depend primarily on your creditworthiness. Because many college students don’t yet have an established credit history or a steady income, co-signers are common.

Private student loan interest rates change frequently and vary by lender. Several key factors determine the rate you’re offered:

Economic conditions: As with federal loans, broader market factors, such as inflation, interest rate trends, and overall economic stability, influence borrowing costs and can push private loan rates up or down.
Lender policies: Each lender has its own pricing model, underwriting standards, and risk tolerance, so rates can vary widely even for borrowers with similar profiles.
Creditworthiness: Private lenders base rates heavily on your credit profile. A higher credit score, strong credit history, good income, and low debt-to-income ratio generally qualify you for lower interest rates. If you apply with a co-signer, their credit and income can significantly influence your rate. A well-qualified co-signer often leads to much lower interest charges.
Loan terms and structure: Rates vary depending on whether you choose a fixed or variable APR, as well as the repayment term length. Shorter terms often offer lower rates.

All federal student loans have fixed interest rates. But when you take out a private student loan, you’ll typically choose between a fixed interest rate or a variable rate. But which one is right for you?

The primary benefit of a fixed interest rate is predictability. Your monthly payment won’t change unless you move to a different repayment plan, making it easier to budget and plan ahead. This stability can be especially valuable if you expect interest rates to rise or if you prefer financial consistency. The trade-off is that fixed rates often start slightly higher than the lowest available variable rates.

On the other hand, variable interest rates may start lower than fixed rates, which can save you money in the short term. They can be a good fit if you plan to pay off the loan quickly or expect market rates to fall. But because variable rates fluctuate with the market, your payments could increase over time. That added uncertainty makes variable rates riskier for long-term repayment or for borrowers who need predictable monthly expenses.

Your student loan interest rate directly affects how much you’ll pay over the life of your loan. Because repayment terms can stretch up to 20 years or more, even small rate changes can significantly impact your total cost.

For example, if you borrow $30,000 on a 10-year term at a 5% interest rate, your monthly payment would be about $318, and you’d pay roughly $8,183 in interest. Raise that rate to 5.5%, and your payment increases by only about $7 a month — but you’ll pay nearly $900 more in interest overall.

That’s why it’s essential to research and compare lenders to secure the lowest rate you qualify for.

Whether you’re a college student or a parent, here are some steps you can take to ensure you get the lowest student loan interest rate:

Try federal loans first: If you’re a college student, you’re more likely to get a low rate through a federal student loan than to try your luck with private lenders. Even if you’re a parent, federal student loans can have competitive rates, as well as more generous relief options if you struggle with repayment.
Shop around: If you’re ineligible for federal student loans or have maxed out your annual allotment, shop around and compare interest rates from multiple private lenders to get an idea of which one will offer you the best deal. You can often prequalify with private lenders to get a better idea of what rate you might qualify for.
Improve your credit: The higher your credit score, the better your odds of getting approved for a low interest rate on a private student loan.
Find a co-signer: If you’re struggling to get a low interest rate on your own, consider asking a parent or other loved one with good credit to apply with you as a co-signer for a private loan.
Consider variable vs. fixed rates wisely: Private lenders may offer lower starting rates on variable loans, but those rates can increase over time. Compare both options to understand the long-term cost before choosing.
Borrow only what you need: Smaller loan amounts mean less risk for lenders, which can sometimes help you qualify for a lower rate. It also keeps your total borrowing cost down.

If you already have student loans with high interest rates, you may have options to limit your costs.

If you have federal student loans, there’s no program offered by the Department of Education that can reduce your interest rate. In fact, the Direct Loan Consolidation program, which you can use to combine multiple loans into one, typically results in a slightly higher weighted-average rate compared to the loans you want to consolidate.

However, you may consider:

Setting up autopay: Whether you have federal or private student loans, you can typically get a 0.25% discount on your interest rate by setting up automatic payments.
Getting on an income-driven repayment plan: If you have federal student loans, an income-driven repayment plan won’t reduce your interest rate. But it can reduce your monthly payment, making it more manageable. These plans can even open up opportunities for forgiveness down the road.
Refinancing your loans: Depending on your credit score and income, you may qualify for a lower rate than what you’re currently paying with a student loan refinance. You can even add a co-signer to improve your chances.

Refinancing may be a no-brainer if you have private student loans and can save money with a refinance loan. But if you have federal loans, keep in mind that you’ll lose access to certain benefits, including student loan forgiveness programs, income-driven repayment plans, and generous forbearance and deferment options.

Before you decide to refinance federal student loans with a private lender, think carefully about your job and income stability, as well as your eligibility for forgiveness, to determine if it’s the right decision for you.
