Interest rates on student loans determine how much extra money you pay back on top of what you borrowed. In simple terms, the interest rate is a percentage of your loan balance that the lender charges you each year. Understanding this rate is key to knowing your total loan cost and planning your repayment.
For federal student loans, the U.S. Department of Education sets fixed interest rates each year. Private lenders set their own rates, which can be fixed or variable. Your rate depends on the loan type, your credit history, and the loan term.
How Do Student Loan Interest Rates Work?
Interest accrues daily on most student loans, meaning interest is calculated based on your current principal balance and your annual interest rate divided by 365 days. This daily interest is added to your loan if you don’t pay it while in school or during deferment.
When you make a payment, it first goes toward any accrued interest, then toward the principal. Paying more than the minimum can reduce your principal faster, which lowers the total interest you pay over time.
Types of Student Loan Interest Rates
There are two main types of interest rates for student loans:
- Fixed rate: Stays the same for the entire life of the loan. Your monthly payment is predictable.
- Variable rate: Can change over time based on market conditions. Your payment may go up or down.
Federal student loans always have fixed rates. Private loans may offer both fixed and variable options. Fixed rates are often higher than initial variable rates, but they offer stability.
Federal Student Loan Interest Rates (2025-2026)
For the 2025-2026 school year, federal loan interest rates are set by Congress and announced each spring. As of August 2026, the rates for loans disbursed between July 1, 2025, and June 30, 2026, are:
| Loan Type | Interest Rate (Fixed) |
|---|---|
| Direct Subsidized/Unsubsidized (Undergraduate) | 6.53% |
| Direct Unsubsidized (Graduate/Professional) | 8.08% |
| Direct PLUS (Parent or Graduate) | 9.08% |
These rates are for loans first disbursed on or after July 1, 2025, and before July 1, 2026. They are fixed for the life of the loan. Rates for the next year (2026-2027) will be announced in May 2026.
Private Student Loan Interest Rates
Private lenders set rates based on your credit score, income, and other factors. As of August 2026, private student loan rates typically range from about 4% to 15% for fixed-rate loans, and variable rates can start lower but increase over time. These rates vary widely by lender and borrower.
Shop around and compare offers from multiple lenders. Be sure to look at the Annual Percentage Rate (APR), which includes fees and reflects the true cost of the loan. A lower APR means lower overall cost.
How to Lower Your Student Loan Interest Rate
You can take steps to get a lower interest rate on both federal and private loans:
- Complete the Free Application for Federal Student Aid (FAFSA) to qualify for federal loans, which often have lower fixed rates than private loans.
- Improve your credit score before applying for private loans, or ask a creditworthy cosigner to apply with you.
- Choose a shorter repayment term if you can afford higher monthly payments—this often comes with a lower rate.
- Consider refinancing after graduation if your credit improves and interest rates drop, but be aware that refinancing federal loans loses federal benefits.
Interest Rate vs. APR: What’s the Difference?
The interest rate is the cost of borrowing the principal amount. The APR includes the interest rate plus any fees, such as origination fees, and is expressed as a yearly rate. For example, a loan with a 5% interest rate and a 1% origination fee may have an APR of about 5.5%.
When comparing loans, always look at the APR because it gives you the true annual cost. Federal loans have an origination fee (currently 1.057% for Direct Subsidized/Unsubsidized loans, and 4.228% for PLUS loans, as of 2025-2026).
How Interest Accrues During School and Grace Periods
For subsidized federal loans, the government pays the interest while you are in school at least half-time and during the six-month grace period after you leave school. For unsubsidized loans, interest begins accruing as soon as the loan is disbursed, and you are responsible for it.
If you don’t pay the interest on an unsubsidized loan while in school, it is capitalized—added to your principal balance. This means you will pay interest on the interest, increasing your total debt. If you can, make interest payments while in school to avoid capitalization.
Practical Tips to Manage Interest Costs
Here are some actionable tips to keep your interest costs low:
- Pay at least the interest that accrues each month, especially on unsubsidized loans.
- Set up automatic payments to get a 0.25% interest rate reduction (common on federal and many private loans).
- Make extra payments toward the principal whenever possible, even if it’s just $20 a month.
- Use any windfalls (tax refunds, bonuses) to make lump-sum principal payments.
- Stay in touch with your loan servicer to explore income-driven repayment plans that lower your monthly payment, but be aware that you may pay more interest over time.
Summary
Understanding what is interest rate on student loans is essential to making informed borrowing decisions. Federal loans offer fixed rates set annually, while private loans vary based on credit. Always compare APRs, know how interest accrues, and make a plan to pay more than the minimum to save money over time. By staying informed and proactive, you can manage your student loan debt effectively and avoid unpleasant surprises.
Frequently Asked Questions
What is a good interest rate for student loans?
A good interest rate depends on the loan type and your credit. For federal undergraduate loans in 2025-2026, the fixed rate is 6.53%, which is considered reasonable. For private loans, rates below 7% are generally good, but they can be higher or lower based on your credit.
How often does student loan interest compound?
Student loan interest compounds daily on most federal and private loans, meaning interest is calculated on your principal plus any unpaid interest. This can increase your balance if you don’t pay the interest as it accrues.
Can I negotiate my student loan interest rate?
For federal loans, the rate is fixed by law and cannot be negotiated. For private loans, you can compare offers from different lenders to get the lowest rate, and you may be able to negotiate with a lender if you have a strong credit profile or a cosigner.
Is a fixed or variable interest rate better for student loans?
A fixed rate is usually better because it stays the same for the life of the loan, making payments predictable. Variable rates can start lower but may increase, leading to higher costs over time. Most experts recommend fixed rates for student loans.
How can I find out the interest rate on my student loans?
You can find your federal loan interest rates by logging into your account at the Federal Student Aid website. For private loans, check your loan documents or contact your lender. Your loan servicer also provides this information on your billing statement.
