Federal loans default to a 10-year Standard Repayment plan, but extended (25-year) and other plans are available and lower the monthly payment while increasing total interest paid — this table shows that tradeoff directly across common term lengths.

Free student loan calculator pre-filled with the real 2026-27 federal Direct Loan rates, showing monthly payment and total interest across all common repayment terms (10/15/20/25 years) side by side — not just one fixed schedule.

  3. See monthly payment, total paid, and total interest for 10, 15, 20, and 25-year terms at once

Frequently asked questions

Why compare multiple repayment terms at once?

Most calculators only show one schedule at a time, hiding the real tradeoff: a longer term lowers your monthly payment but meaningfully increases total interest paid over the life of the loan. Seeing all the common terms side by side makes that tradeoff concrete.

Are these the actual current federal rates?

Yes — 6.52% for undergraduate Direct Loans, 8.07% for graduate Direct Loans, and 9.07% for PLUS loans, all fixed for loans first disbursed between July 1, 2026 and June 30, 2027, per the US Department of Education.
