Debt Payoff Calculator

See exactly when you'll be debt-free, how much interest you'll pay, and how much you'd save by paying a little extra each month.

How the math works

This calculator simulates your loan month-by-month. Each month, interest accrues on your current balance at the monthly rate (APR ÷ 12), and your payment is applied - first to interest, then to principal. We repeat the loop until the balance hits zero.

Why extra payments matter so much

Because extra payments go straight to principal, they cut the balance that future interest is charged on. The earlier in the loan you pay extra, the more compounding you avoid. That's why even $50 extra a month can save thousands in interest over time.
