Student loan repayment calculator (US)

Enter your balance, interest rate and expected salary to compare fixed monthly payments over 10, 20 and 25 years, plus what each costs in total interest.

How student loan payments are calculated

A standard plan uses a fixed monthly payment that clears the loan, with interest, by the end of the term. Longer terms lower the monthly payment but cost much more in interest.

Federal loans also offer income-driven repayment, where payments are a share of your discretionary income, and the federal rules changed for loans taken out from July 2026. Check your options and current rates at studentaid.gov, and talk to your servicer before choosing a plan. Private loans follow your lender's terms.
