Yes, student loans have interest. Interest is the cost you pay to borrow money, and it applies to both federal and private student loans. The rate you get depends on the loan type, your credit, and when the loan was disbursed.
Understanding how interest works helps you plan repayment and save money. This guide explains the basics, including when interest starts, how it’s calculated, and what you can do to pay less over time.
How Does Student Loan Interest Work?
Interest is calculated as a percentage of your unpaid loan balance. Your lender adds this charge to your account daily or monthly, depending on the loan.
For federal loans, interest is simple interest. That means it’s based only on the principal amount you borrowed, not on previously accrued interest. Private loans may use simple or compound interest, so check your loan terms.
When you make a payment, it first covers any accrued interest, then reduces the principal. If your payment isn’t enough to cover the interest, the unpaid interest can capitalize, meaning it gets added to your principal balance.
When Does Interest Start Accruing?
For most federal loans, interest starts accruing as soon as the loan is disbursed, even while you’re in school. Subsidized federal loans are the exception—the government pays the interest while you’re enrolled at least half-time and during grace periods.
Private loans typically accrue interest from the day the loan is funded. Some private lenders offer interest-only payments while you’re in school, but interest still builds.
During deferment or forbearance, interest may continue to accrue. For unsubsidized loans, you’re responsible for that interest. If you don’t pay it, it capitalizes, increasing your total debt.
What Are Current Interest Rates?
Interest rates for federal student loans are set by Congress each year and are fixed for the life of the loan. For loans disbursed between July 1, 2025, and June 30, 2026, the rates are:
| Loan Type | Undergraduate | Graduate | Parent PLUS |
|---|---|---|---|
| Direct Subsidized/Unsubsidized | 6.53% | 8.08% | N/A |
| Direct PLUS | N/A | 9.08% | 9.08% |
Private student loan rates vary widely based on your credit score, income, and the lender. As of August 2026, fixed rates can range from around 4% to 15%, and variable rates from 3% to 12%. These rates change frequently, so shop around.
How Is Interest Calculated?
Lenders use a daily interest formula. To find your daily interest, divide your annual interest rate by 365, then multiply by your current principal balance.
For example, if you have a $10,000 loan at 5% interest, your daily interest is about $1.37. Over a month, that adds up to roughly $41 in interest.
Your loan servicer applies this interest to your account each day. When you make a payment, it first covers the interest that has accrued since your last payment, then the rest goes to the principal.
How to Reduce the Interest You Pay
Even though interest is unavoidable, you can take steps to lower the total amount you pay:
- Make payments while you’re in school, even if they’re small. This prevents interest from capitalizing.
- Pay more than the minimum each month. Extra payments go directly to the principal, reducing future interest.
- Set up autopay to get a 0.25% interest rate reduction on federal loans. Many private lenders offer similar discounts.
- Consider refinancing after graduation if you have good credit and stable income. You might qualify for a lower rate.
Also, look into income-driven repayment plans for federal loans. These plans can lower your monthly payment, but keep in mind that interest still accrues, and any forgiven balance after 20 or 25 years may be taxable.
What About Loan Forgiveness and Interest?
Under Public Service Loan Forgiveness (PSLF), your remaining balance is forgiven tax-free after 120 qualifying payments. Interest that accrues during that period is also forgiven, but you must work for a qualifying employer and make payments under an income-driven plan.
Other forgiveness programs, like Teacher Loan Forgiveness, can cancel up to $17,500 of your loans, but interest accrued before forgiveness is not waived.
If you’re in default, interest continues to accrue, and collection costs can add to your balance. Contact your loan servicer to discuss options like rehabilitation or consolidation.
Practical Summary
Student loans do have interest, and the rate depends on the loan type and your credit. Federal loans offer fixed rates and borrower protections, while private loans vary. To minimize interest costs, make payments during school, pay more than the minimum, and consider autopay discounts. Always read your loan terms and ask your servicer about repayment options that fit your budget.
