Frequently asked questions
Enter your balance, APR, and either your monthly payment or a target number of months. In 'Payoff time' mode it simulates the balance month by month, applying interest at APR ÷ 12 each month, and reports how long the card takes to clear plus the total interest. In 'Required payment' mode it uses the standard amortization formula to find the level monthly payment that clears the balance in exactly the months you choose.
If your monthly payment is less than or equal to one month's interest on the balance, the interest charged each month is at least as large as your payment, so the balance never goes down. The calculator flags this instead of showing an impossible payoff date. Increase the monthly payment above the monthly interest to make progress.
No. It assumes a fixed APR, no new charges, and no annual or late fees. It also uses simple monthly compounding (APR ÷ 12), while many issuers compound daily. Treat the result as a close estimate; your statement is the source of truth.
