About this calculator
Use the Credit Card Payoff Calculator to plan how to pay off a debt. It reads your credit card balance, annual interest rate or APR and monthly payment, computes the payoff time and total interest with amortising the balance against your payment, and shows the result clearly labelled. Because the calculation happens in your browser, your figures never leave the page and there is nothing to install.
If your payment is less than the monthly interest, the balance grows instead of shrinking — the tool flags this so you can raise the payment.
How to use
- Enter your credit card balance.
- Enter the card’s annual interest rate (APR).
- Enter the fixed monthly payment you will make.
- Press Calculate to see the payoff time and interest.

Technical notes
Credit Card Payoff Calculator amortises each balance at its APR and minimum payment to project the months to clear it and the total interest paid.
Figures assume the rate and amounts you enter stay fixed and exclude fees, taxes and charges unless a field asks for them.
Because it runs locally, results appear instantly with no server round-trip.
FAQ
Why must my payment beat the monthly interest?
If the payment is less than the interest charged that month, the balance grows instead of shrinking, so the card is never paid off. The tool flags this.
How is credit card interest charged?
Card APR is applied monthly to the outstanding balance. Paying more than the minimum reduces the balance faster and cuts total interest sharply.
Does this assume no new spending?
Yes. It assumes a fixed payment and no further charges. New purchases would increase the balance and extend the payoff time.
Does the Credit Card Payoff Calculator send my data to a server?
No. The Credit Card Payoff Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
