Credit Card Payoff Calculator

Estimate how many months a fixed monthly payment takes to clear a credit card balance, how much interest that is, and what a different payment would change. It is a simplified estimate, not a statement from your card issuer.

What This Estimate Assumes

  • The APR is divided by 12 to give an equal monthly rate.
  • Interest is charged on the balance at the start of each month, before that month's payment, and the payment is made at the end of the month.
  • The same payment is made every month. The last payment is whatever is left.
  • A remaining amount of half a paisa or less may be included in the final payment.
  • No new purchases, fees, penalties, rewards, taxes or promotional rates are included.
  • No card issuer's minimum-payment or billing-cycle rules are modelled. Real cards may charge interest on daily balances and statement cycles, so a real payoff can differ.
  • This is an estimate, not a statement or a payoff quote, and not financial advice. Figures are rounded to the paisa from unrounded values, so figures added by hand can differ by a paisa.

How to Use the Credit Card Payoff Calculator

  1. Enter the balance you owe, the card's annual percentage rate and the fixed amount you would pay each month.
  2. Press Calculate. The result says how many monthly payments it would take, the interest in total, the total repaid, the interest in the first month and the size of the last payment.
  3. To see what a different payment would change, enter it in the optional box and press Calculate again.
  4. If you change a value after calculating, the result is marked as out of date until you press Calculate. Load example fills in a sample, and Reset clears everything.

Worked Example

Take a balance of ₹50,000 at an APR of 36%, paid at ₹3,000 a month. The monthly rate is 36% ÷ 12 = 3%, so the first month's interest is ₹1,500.00. The payment clears that interest and ₹1,500.00 of the balance, and the balance falls from there. It takes 24 payments, the last being ₹1,360.29. The total interest is ₹20,360.29 and the total repaid is ₹70,360.29.

At ₹4,000 a month the same balance takes 16 payments with ₹13,607.80 of interest. Compared with ₹3,000, that is 8 months fewer and ₹6,752.50 less interest. The 36% and the amounts are only an illustration, not a typical rate.

How the Calculation Works

Each month the tool takes the balance at the start of the month, adds one month of interest (the APR divided by 12 of that balance), then subtracts your payment. The remaining balance carries into the next month. When what is owed is no more than your payment, that last payment is just what is left. The figures are worked out with exact integer arithmetic on paise, so the paisa shown is the paisa the model gives. It stops after 600 months (50 years).

It shows no payoff date. It counts payments from now, and a real card's dates, statements and due dates are not part of the model.

Why a Payment May Not Reduce the Debt

Interest is charged every month on what is still owed. If your payment is no more than that month's interest, none of it goes towards the balance: the balance stays the same or grows. The tool says so and shows the first month's interest and the smallest payment that is above it. It does not say what you should pay.

A payment only just above the interest works very slowly. For ₹1,00,000 at 12% a year the first month's interest is ₹1,000.00. A payment of ₹1,001 or ₹1,002 still leaves a balance after 50 years, so the tool shows no payoff time. At ₹1,005 it takes 533 payments, and at ₹1,500 it takes 111.

Comparing Two Payments

When you add a second payment, both are worked out for the same balance and APR and shown side by side. If both pay the balance off, the tool states how many months more or fewer the second takes and how much more or less interest it costs. If either does not pay off within 50 years, no difference is shown, because there is nothing to subtract. The comparison only describes the model; it does not suggest which payment to choose.

Credit Card Payoff Calculator FAQ

Is this my card's exact payoff?

No. It is a simplified estimate. Real cards can charge interest on daily balances and statement cycles, and add fees and new purchases, so your card's figures can differ. Check your own statement for the real numbers.

Why does my payment not reduce the balance?

When the payment is no more than one month's interest, all of it goes to interest under this model. The result shows the first month's interest so you can see this.

What happens if I pay only the minimum?

This tool does not model any issuer's minimum-payment rule, so it cannot say. It shows what a fixed monthly payment that you choose would do.

Does it include fees or new purchases?

No. It assumes the balance only changes through interest and your payments.

Is my data stored or sent anywhere?

No. The figures are worked out in your browser, nothing is stored or sent to ToolZen Hub, and no card details are asked for. Reloading the page clears everything.
