What This Calculator Does

The Credit Card Payoff Estimator shows you how long it will take to clear a credit card balance given your current balance, interest rate (APR), and the monthly payment you plan to make. It produces a full month-by-month amortisation schedule, so you can see exactly how much of each payment goes to interest and how much reduces the debt.

Who it is for: Anyone carrying a credit card balance who wants to make a concrete payoff plan. It is equally useful whether you have one card or are trying to compare payoff scenarios before prioritising debts.

When to use it: Use it when you receive your statement and want to know the true cost of making only the minimum payment, when you have received a balance transfer offer and want to compare outcomes, or when you are planning a budget and need to set a realistic payoff timeline.

Limitations: This calculator assumes a fixed monthly payment and a fixed APR throughout the payoff period. It does not account for new purchases added to the balance, annual fees, or penalty rates that may apply if you miss a payment. If you continue to use the card while paying it down, your actual payoff date will be later than shown.

How the Calculation Works

Credit card interest is typically stated as an Annual Percentage Rate (APR), but it compounds monthly. Each month, the lender calculates your interest charge by dividing your APR by 12 and applying it to your current balance. Your payment then reduces the remaining balance by the amount left over after interest is covered.

Monthly Interest = Current Balance × (APR ÷ 12)
Principal Paid = Monthly Payment − Monthly Interest
New Balance = Current Balance − Principal Paid

This repeats each month. Because your balance shrinks, the interest charge also falls slightly each month — which means a growing proportio
