How do I calculate my monthly student loan payment?

Pick a loan type, enter your Loan balance and Term, and the Monthly payment, Total interest, Total paid and Payoff date appear. Choose Custom or edit the Interest rate to use your own rate.

What interest rates does it use for federal loans?

Undergraduate, Graduate and PLUS load the 2026-27 federal rates: 6.52%, 8.07% and 9.07%. These reset annually, so verify current terms with your servicer. Editing the rate switches to Custom.

How do I see how much extra payments save?

Enter an amount in Extra payment. The tool shows how much interest you save and how many months earlier the loan is paid off, compared with the baseline without extra payments.

What does the grace period and Subsidized option do?

Grace period adds months before repayment starts. Ticking Subsidized means no interest accrues during grace; otherwise interest builds up first and is included in the balance you repay.

Why does it say my loan never pays off?

The payment does not cover the monthly interest, so the balance never falls. Increase the Term or the payment. You can also export the month-by-month schedule using Download CSV.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install.
