Credit Card Payoff Calculator

How to use this calculator

Enter your card balance, APR, minimum payment, and planned extra payment. The tool estimates payoff months, total paid, and interest avoided versus minimum-only style payments.

When this calculator is useful

• Creating a card payoff plan
• Prioritizing high-interest debt
• Explaining why minimum payments can keep balances around for years

Important limitations

This simplified model assumes a fixed payment and no new spending on the card.

For best results, run at least three cases: a conservative case, a middle case, and a stretch case. If a small change in inputs creates a big change in the answer, that is a sign the decision may be sensitive to rates, fees, timing, or market performance.
