About the Credit Card Payoff Calculator

The Credit Card Payoff Calculator shows how long a card balance takes to clear and the interest it costs, comparing minimum payments against a fixed amount. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Seeing what paying only the minimum really costs.
  • Choosing a payment that clears the card within a target time.
  • Deciding whether a balance transfer is worth the fee.
Paying the minimum on a high-APR card can take well over a decade and cost more in interest than the original balance. This tool prints both scenarios side by side so the gap is visible.
