Understanding federal student loan interest rates is key for borrowers planning to finance their education. These rates, updated annually, influence the total cost of borrowing and repayment. For students and parents alike, knowing what to expect in 2025 can make the decision-making process more informed.
How Federal Student Loan Interest Rates Are Set
Federal student loan interest rates aren’t random—they’re calculated based on specific economic benchmarks and policies. Set annually, they depend on factors like the 10-year Treasury note auction as well as statutory add-ons determined by Congress. Once fixed, these rates remain stable for the life of the loan.
The Impact of the 10-Year Treasury Note
The 10-year Treasury note plays a pivotal part in setting federal student loan interest rates. Each May, the U.S. Treasury conducts an auction, and the highest yield determines the foundation for student loan rates applied in the following academic year starting July. For example, in 2024, the high yield in May stood at 4.483%, shaping the rates for loans disbursed until mid-2025.
Understanding Statutory Add-On Rates
From that yield, statutory add-ons are applied to finalize the rates. These add-ons differ based on loan types:
- Subsidized and Unsubsidized Undergraduate Loans: 2.05%
- Graduate Unsubsidized Loans: 3.6%
- PLUS Loans: 4.6%
This equation ensures interest rates match economic trends while keeping federal loans competitively priced compared to private alternatives. More details on specific percentages can be found on the Federal Student Aid site.
Federal Student Loan Interest Rates for 2025
When it comes to borrowing in 2025, federal loan interest rates reflect both inflation trends and economic policies. Below is a breakdown of rates for various loan types.
Undergraduate Loan Rates in 2025
Undergraduate students borrowing subsidized or unsubsidized loans during 2024–2025 will see a fixed interest rate of 6.53%. This represents a slight increase compared to prior years, which had rates at 5.05% in 2021 and 4.99% in 2020. While these loans remain one of the most affordable borrowing options, the gradual increases signify growing financial burdens for many students.

Graduate and Professional Loan Rates in 2025
Graduate students taking out unsubsidized loans in 2025 will lock in an interest rate of 8.08%. Comparing this to previous years, the spike from 6.54% in 2023 shows the rising cost of borrowing for advanced education. As graduate students aren’t eligible for subsidized loans, this rate is crucial to understanding total education expenses.

PLUS Loan Rates for Parents and Grad Students
For PLUS loans, the interest rate climbs higher, set at 9.08% for the 2024–2025 period. These loans, primarily for parents or grad students needing additional funds, have traditionally been higher due to added risk perceived by lenders. As a result, they’re often viewed as a “last-resort” option for financing an education.

Federal vs. Private Loan Interest Rates in 2025
While federal loans have fixed rates, private lender interest rates provide a wide variety based on borrower profiles, lender terms, and economic conditions. In 2025, private student loan rates for undergraduates can range from 3.47% to over 16.24%.
Why Federal Loan Rates Are More Stable
The chief benefit of federal loans lies in their predictability. Federal rates won’t suddenly spike over time, offering borrowers stability in their financial planning. Additionally, federal programs offer protections—like income-driven repayment plans and deferment options—that are unrivaled by private loans.
The Risks of Private Loan Rate Fluctuations
Private loans are highly dependent on creditworthiness and may tempt borrowers with low introductory rates. However, variable rates mean they can escalate quickly, leaving borrowers vulnerable to market shifts. Before choosing a private loan, it’s essential to weigh its risks against the stability of federal loans.

Federal Loan Benefits: Flexibility and Security
Federal loans also come with flexible repayment structures and potential forgiveness options. Borrowers considering private refinancing must weigh these benefits carefully, as refinancing federal loans forfeits these safety nets.
Final Thoughts on 2025 Student Loan Interest Rates
Federal student loan interest rates set the tone for educational borrowing and repayment. For 2025, with rates for undergraduate loans at 6.53%, grad loans at 8.08%, and PLUS loans at 9.08%, students and parents face growing costs in higher education. Borrowers should stay informed, plan strategically, and explore government protections to make the best decisions for their financial future.
