What is Credit Card Payoff?

This calculator estimates how many monthly payments it takes to clear a credit card balance when you choose the payment amount. It charges one month of interest to the remaining balance, applies the payment, and repeats until the final smaller payment closes the balance. The result includes the number of payments and the total amount paid.

The estimate assumes a constant APR, one payment per month, no new purchases, and no fees. Actual card interest may be calculated daily and statement cycles vary, so an issuer’s payoff amount can differ. Select the same currency for the balance and payment; the page labels money but does not perform currency conversion.

How to Use This Calculator

  1. Enter the starting credit card balance and choose its currency.
  2. Enter APR as a yearly percentage. Enter 24 for 24%.
  3. Enter the amount you plan to pay each month and select the same currency as the balance.
  4. Select Calculate. Each month, the calculator multiplies the unpaid balance by APR ÷ 12 ÷ 100, adds that interest, and then applies the payment.
  5. The last payment is limited to the amount actually due, so total paid is not overstated. The answer shows whole payment months and total paid to five decimal places.

If the regular payment is no greater than first-month interest, the balance cannot decline under these assumptions and the page returns an error.

Formula Used

Monthly rate r = APR ÷ 100 ÷ 12.

For each month: amount due = previous balance × (1 + r); actual payment = the smaller of regular payment and amount due; new balance = amount due − actual payment.

Total paid is the sum of every actual payment, including the smaller final payment. The process stops when the balance reaches zero.

Worked Example

Take a $1,000 balance, 24% APR, and a $100 monthly payment. The model’s monthly rate is 2%. In month one, interest is $20, so $100 leaves $920. Month two adds $18.40 and leaves $838.40 after payment. The balance continues to shrink as the interest charge falls.

After the eleventh $100 payment, $26.50277 remains. Month twelve adds about $0.53006 of interest, so the final payment is about $27.03282 rather than another $100. Payoff therefore takes 12 monthly payments and total paid is about $1,127.03282. Of that amount, approximately $127.03 is interest under this monthly model.

Why Use This Calculator?

The month count tells you how many monthly payment dates the modeled schedule needs. Total paid combines the original balance and accumulated interest. A larger payment generally shortens the schedule and reduces interest because less balance remains for later periods. A payment only slightly above monthly interest can create a very long payoff period.

Use the output to compare payment scenarios and plan a budget, then check the card statement and issuer’s payoff information. The result is not a promise that an account will close on that date. Payment timing, daily interest, fees, rate changes, and new transactions can all change the real total.

Common Mistakes

    • Using different currencies for balance and payment. A $100 payment cannot be applied directly to a €1,000 balance without an exchange rate.
    • Entering 0.24 for a 24% APR. The form expects 24.
    • Choosing a payment that is equal to or below the first month’s interest. The modeled balance will not fall.
    • Assuming every payment equals the regular amount. The final payment is normally smaller.
    • Ignoring new purchases, cash-advance rates, annual fees, or late charges.
    • Comparing the monthly model with a statement’s daily-interest figure without allowing for different timing conventions.

Frequently Asked Questions

Why is the last payment smaller?

Once the balance plus that month’s interest is less than the regular payment, only the amount due is needed. Limiting the final payment prevents the estimate from counting money that would not be owed.

Why does the calculator reject a small payment?

If the payment is no greater than the first monthly interest charge, it cannot reduce the starting balance in this model. The balance would remain level or grow, so there is no finite payoff date.

Does total paid include new purchases and fees?

No. It includes the entered starting balance and interest produced by the constant APR model. Stop using the card and account for any fees separately if you want a scenario closer to a pure payoff plan.

Why can the issuer quote a different payoff total?

Many issuers calculate interest with daily balances, while this tool uses twelve equal monthly periods. Statement dates, payment posting, fees, variable rates, and residual interest can all change the issuer’s figure.

What happens at zero percent APR?

No interest is added. The calculator counts full regular payments plus a smaller final payment when needed, and total paid equals the starting balance.
