How extra student loan payments work

Student loans on a fixed standard plan amortize like other installment loans: each month covers interest first, then principal. Anything above the scheduled payment goes straight to principal, which shortens the remaining schedule and removes future interest. This tool compares the original term against the same loan with your extra amount. It does not model income-driven repayment, forbearance, capitalization events, or forgiveness programs.
