Enter your current loan balance, annual interest rate, and any extra monthly payment you can afford. The calculator uses the standard amortization formula M = P[r(1+r)^n] / [(1+r)^n − 1] to compute your minimum 10-year payment, then shows you how much interest you save by paying more each month.
Every extra dollar reduces your principal faster, which lowers the interest that accrues each month. On a $30,000 loan at 6.5%, paying just $100 extra per month can save over $2,500 in interest and shave more than two years off your repayment timeline.
Federal student loans (Direct Subsidized, Unsubsidized, PLUS) typically carry fixed rates set by Congress each year. Private student loans may have variable rates that change over time. Always confirm whether your loan has prepayment penalties before making extra payments — most federal loans have none.
