The true cost of borrowing for education in the United States depends on far more than the headline interest rate. For federal loans, interest rates are set annually and differ based on academic level and loan type, while the origination fee is deducted from the disbursed amount. For example, undergraduates saw a subsidized loan interest rate of 5.50% in 2024–2025, while PLUS loans for parents and graduate students came with an 8.05% rate. Origination fees, though seemingly minor, can amount to hundreds of dollars on larger loans and increase the effective borrowing cost.
Private loan rates depend on market factors and individual credit profiles. Some private lenders offer enticingly low variable rates to highly qualified applicants, but these rates can change with economic conditions. Fixed rates provide predictability but are often higher on average. No-fee promises from lenders like SoFi appeal to cost-conscious students, but the real expense is revealed over the life of the loan, especially for those who defer payments while in school.
Compound interest—the accrual of interest on interest—can substantially increase the overall repayment amount, particularly for unsubsidized federal or private loans. Students who delay payments until after graduation could face higher balances due to accumulated interest during school. For this reason, even small payments during enrollment can make a significant difference in long-term financial outcomes.
Comparing expected salaries in chosen fields to projected monthly loan payments is an essential part of determining the sustainability of borrowing. Free online tools provided by the U.S. Department of Education help students estimate repayment schedules, total interest paid, and eligibility for income-driven plans, supporting informed decisions that align educational aspirations with future financial capabilities.
