Debt Payoff Calculator

This debt payoff calculator takes all of your debts, balances, rates, and minimum payments, plus the total amount you can put toward debt each month, and produces a complete payoff plan: your debt-free date, total interest, and the exact order to attack each debt. Enter each debt once and the calculator applies the rollover method automatically, where every paid-off debt's payment gets redirected to the next one instead of disappearing back into your budget.

Example: $15,000 across three debts with a $600 monthly budget reaches debt-free in about 29 months, versus 11+ years making minimum payments only.

The debt snowball method pays minimums on everything and directs all extra money at the smallest balance first. When that debt dies, its entire payment rolls into the next smallest. The math is rarely optimal, but the quick early wins keep people motivated, and the best payoff strategy is the one you actually stick with.

The debt avalanche method targets the highest interest rate first, which minimizes total interest paid and is mathematically the cheapest path out of debt. The debt avalanche calculator mode shows the same complete plan, payoff order, dates, and total interest.

Credit card minimum payments are designed to keep debt alive for decades. Minimums typically cover interest plus a sliver of principal, so an $8,000 balance at 22% APR on minimums alone takes over 20 years to clear and costs more in interest than the original debt.

Every dollar above the minimums goes entirely at principal on your priority debt, and its effect compounds through the rollover. Even $50 extra per month meaningfully moves the debt-free date on most real debt loads.
