How the debt payoff math works

At the start of each modeled month, this calculator applies approximately one month’s interest (current balance × APR ÷ 12), then pays the required minimums. It directs the remaining monthly budget to the smallest current balance (snowball) or highest APR (avalanche). When a debt is paid off, its former payment capacity is rolled into other debts. Figures are rounded to cents each month.

Your total initial payment budget stays fixed until the final month. The calculator assumes fixed APRs and minimum payment amounts, no new borrowing, no fees, and payments made on schedule. Real creditors may accrue interest daily, change minimums, or charge fees, so your actual payoff figures can differ. If a plan cannot pay everything off within 60 years, the tool shows that limitation instead of inventing a payoff date.

For urgent debt problems, missed payments, or hardship, consider contacting the lender or an independent nonprofit credit counselor. This calculator is an educational planning aid, not individualized financial advice.
