An estimate from the inputs shown, not a promise of a particular date. How we calculate this.

Enter the balance, the rate and what you pay now, then add an extra amount. The answer above is the same payoff engine run with the extra and again without it, and the gap between those runs, if any, is what the extra buys.

A student loan is an installment loan: a level payment, a set term, interest charged on what is still owed. Paying above the required amount can shorten the term and, where interest is being charged, reduce it — provided the extra reaches the principal rather than being held against a future payment. The answer above says which of those applies to your numbers.

Assumptions

  • Interest accrues once a month, before that month's payment.
  • The APR stays at 6.53% for the whole term.
  • No new spending, fees, penalty rate or promotional rate.
  • You pay the payment plus the extra in full, on time, every month.

What this does and does not model

Interest on most student loans keeps accruing on the outstanding principal, and interest that accrued while you were in school may have been capitalized — added to the principal, so that it earns interest itself. This calculator charges interest once a month on the balance you enter; a servicer that accrues it on a different schedule will show slightly different figures. Enter today's balance, including any capitalized interest, rather than the amount you originally borrowed.

Income-driven repayment, deferment, forbearance and forgiveness all change the payment and sometimes the balance, and a variable-rate private loan changes the rate. None of those are modelled here. The estimate holds for a fixed-rate loan on a standard schedule, paid in full and on time.

Make sure the extra goes where you think it does

A student-loan payment is generally applied to fees owed, then to interest, then to the principal. An amount above the required payment is sometimes credited against a future payment instead of reducing the principal, which moves the next due date rather than shortening the loan. The Consumer Financial Protection Bureau's guidance is to instruct your lender or servicer to apply the excess directly to the principal balance. The next statement is where you can see whether it did.

If you have several loans

Paying the highest-rate loan ahead of the others costs the least interest in total; clearing the smallest balance ahead of the others removes a whole loan sooner. Both are legitimate orders, and the difference between them on your own loans is measurable rather than a matter of opinion — the comparison pages linked below run both.

The dates printed here were computed from a plan starting September 2026; the calculator re-anchors to the current month in your browser, so a date you read with JavaScript disabled is the one for that starting month rather than for today.
