About the Credit Card Payoff Calculator

Credit Card Payoff Calculator estimates how one card balance could be paid down. Enter the balance, the APR and either your own fixed monthly payment or the number of months you want to clear it in. You can add a one-time extra payment with the first payment and, in payment mode, a recurring extra each month. The tool shows the estimated payoff time and date, total interest, total paid and a month-by-month schedule.

The estimate uses simple, clearly stated assumptions: no new purchases or fees, monthly interest of APR ÷ 12 on the balance, and payments at the end of each month. Card issuers usually work differently — interest is often charged on the average daily balance, purchases, cash advances and balance transfers can have different rates, and grace periods, fees and payment-allocation rules all matter — so treat the result as a guide and check your card agreement or statement for exact figures. If a payment does not cover the interest, the tool warns you instead of showing a payoff date.

Frequently asked questions

How is interest calculated here?

Each month, interest = balance × APR ÷ 12, rounded to the nearest cent or paisa, is added before the payment. This is a simplification; many issuers use the average daily balance and other rules, so your statement may differ.

Why does it say my payment does not cover the interest?

If the monthly payment is not more than the monthly interest, the balance never goes down, so there is no payoff date. Enter a higher payment to see an estimate.

How does target-months mode work?

It solves the standard payment formula for the number of months you choose, allowing for any one-time extra payment, and rounds the payment up to the next cent so the balance clears within that time.

Does it use a minimum-payment formula?

No. Issuers set their own minimum-payment rules, so the tool only uses the payment amount you enter or the payment needed for your target months.

Are new purchases or fees included?

No. The estimate assumes no new purchases, fees, rate changes or promotional rates. Any of these would change the result.

What are the limits?

A balance above zero up to 100 billion, an APR from 0% to 100%, and up to 600 months (50 years). Payments that would take longer, or that never reduce the balance, are rejected with a message.

Does the currency selector convert amounts?

No. It only changes the symbol shown (₹, $, €, £ or none). No exchange rate is used and the calculation is identical whichever symbol you pick.

Is anything I enter stored or sent anywhere?

No. Calculations run in your browser on your device. Amounts, rates, results and tables are not uploaded and are not saved in browser storage. Reset clears them from the page.
