Student loan interest rates determine how much extra you pay on top of what you borrow. For the 2026-27 school year, federal undergraduate loans carry a fixed rate of 5.50%, while graduate loans are 7.05% and PLUS loans are 8.05%. Private student loan rates vary widely, often ranging from about 4% to 15% depending on your credit and other factors.
Your interest rate matters because it affects your monthly payment and the total amount you repay over time. Even a small difference in rate can add up to thousands of dollars over a 10-year repayment term. Understanding how rates work helps you make smarter borrowing decisions.
How Federal Student Loan Interest Rates Work
Federal student loans have fixed interest rates set by Congress each year. These rates are based on the 10-year Treasury note auction held in May, plus a fixed add-on percentage. The rates for loans disbursed between July 1, 2026, and June 30, 2027, are listed below.
| Loan Type | Interest Rate (2026-27) | Borrower Type |
|---|---|---|
| Direct Subsidized and Unsubsidized | 5.50% | Undergraduate |
| Direct Unsubsidized | 7.05% | Graduate or Professional |
| Direct PLUS (Grad PLUS and Parent PLUS) | 8.05% | Graduate or Parent |
These rates are fixed for the life of the loan, meaning they will not change as market conditions move. That provides predictable monthly payments, which can help with budgeting.
How Private Student Loan Interest Rates Work
Private student loans are offered by banks, credit unions, and online lenders. Their interest rates can be fixed or variable. Fixed rates stay the same, while variable rates can change over time based on market indexes like the Secured Overnight Financing Rate (SOFR).
Private lenders determine your rate based on your credit score, income, and other debts. Students with limited credit history often need a co-signer to qualify for a lower rate. Rates for private loans can be as low as 4% for excellent credit, but they can climb above 15% for riskier borrowers.
Because private loans lack the borrower protections of federal loans, it is usually wise to exhaust federal options first. Federal loans offer income-driven repayment plans, loan forgiveness programs, and deferment options that private lenders rarely match.
How Interest Accumulates on Student Loans
Interest on student loans accrues daily. The daily interest amount is calculated by dividing your annual interest rate by 365 days, then multiplying by your current principal balance. For example, a $10,000 loan at 5.50% accrues about $1.51 in interest per day.
For subsidized federal loans, the government pays the interest while you are in school at least half-time, during the grace period, and during deferment. For unsubsidized loans, you are responsible for all interest that accrues from the first day of disbursement.
If you do not pay the interest while in school, it is capitalized, meaning it is added to your principal balance. This can increase the total amount you owe and lead to higher monthly payments after graduation.
Current Rates and Recent Trends
Federal rates have fluctuated in recent years. For the 2025-26 school year, undergraduate rates were 5.50%, the same as the current 2026-27 rate. In the 2024-25 year, they were 6.53%, and in 2023-24 they were 5.50%. Rates tend to move with the economy, so they can rise or fall from year to year.
Private loan rates have also shifted, often following the Federal Reserve’s benchmark rate. As of August 2026, the Fed has kept rates steady, which means private loan rates remain relatively stable. However, they can vary significantly by lender and borrower profile.
How to Lower Your Student Loan Interest Rate
You cannot change the rate on an existing federal loan unless you refinance, but you can take steps to get better rates on new loans:
- Apply with a creditworthy co-signer to improve your chances of a lower rate.
- Compare offers from multiple private lenders to find the best deal.
- Choose a shorter repayment term, which often comes with a lower rate.
- Improve your credit score by paying bills on time and reducing debt.
Refinancing after graduation can also lower your rate if your credit has improved or market rates have dropped. However, refinancing federal loans makes you lose federal benefits, so weigh the pros and cons carefully.
Fixed vs. Variable Rates: Which Is Better?
Fixed rates offer stability and are a safe choice for most borrowers. Variable rates can start lower but carry the risk of increasing over time. If you plan to repay quickly, a variable rate might save money, but for long-term loans, fixed rates are generally safer.
Consider your risk tolerance and financial situation. If you value predictable payments, choose a fixed rate. If you can handle some uncertainty and expect rates to stay low, a variable rate might be tempting, but it is not recommended for most students.
Summary
Student loan interest rates for 2026-27 are 5.50% for federal undergraduate loans, 7.05% for graduate loans, and 8.05% for PLUS loans. Private loan rates vary from about 4% to 15% depending on credit and market conditions. Always maximize federal loans first, compare private offers, and consider refinancing only if you understand the trade-offs. Knowing your rate and how it accrues helps you plan repayment and save money over the long term.
