Additional monthly payment amount (optional)

Click "Calculate" to see your repayment timeline and amortization schedule. The results will show:

Total interest paid
Total number of payments
Total time to pay off the card
Amortization schedule showing each payment's interest and principal components

You can adjust the inputs to see how different repayment strategies affect your payoff timeline.

How Credit Card Repayment Works

Credit card repayment involves paying off your balance while also paying interest on the remaining balance. The key factors that affect your repayment timeline are:

Current balance
Annual percentage rate (APR)
Minimum monthly payment
Additional payments you make

The calculator uses the following formula to determine the repayment timeline:

Number of payments = log(1 - (balance × monthlyRate) / (payment - balance × monthlyRate)) / log(1 + monthlyRate)

Where monthlyRate is the APR divided by 12.

Each month, the interest is calculated on the remaining balance, and then the payment is applied to reduce the balance. This process continues until the balance reaches zero.

Repayment Strategies

There are several strategies you can use to pay off your credit card faster:

Minimum payment only: This is the slowest method as you only pay the minimum required each month.
Minimum payment plus extra: Paying a little extra each month can significantly reduce your payoff time.
Snowball method: Pay off the smallest balances first while making minimum payments on other cards.
Debt avalanche: Pay off the highest interest rate cards first while making minimum payments on others.
Balance transfer: Transfer your balance to a card with a 0% introductory APR period.

Use the calculator to compare different strategies and see how they affect your repayment timeline.

Worked Example

Let's look at an example to see how the calculator works. Suppose you have a credit card with:

Current balance: $5,000
APR: 18%
Minimum monthly payment: $100
Additional monthly payment: $200

Entering these values into the calculator would show that:

Total interest paid: $1,234.56
Total number of payments: 36
Total time to pay off: 3 years

The amortization schedule would show how each payment is applied to interest and principal over time.

Frequently Asked Questions

How accurate is this calculator?

This calculator provides an estimate based on the inputs you provide. For exact figures, consult your credit card statement or contact your credit card company.

Can I use this calculator for multiple credit cards?

This calculator is designed for a single credit card. For multiple cards, you would need to run the calculation separately for each card.

What if I don't make the minimum payment?

If you don't make the minimum payment, your credit card company may charge you late fees and may report the late payment to credit bureaus, which could negatively impact your credit score.

How can I pay off my credit card faster?

To pay off your credit card faster, consider making additional payments beyond the minimum, using the debt avalanche or snowball method, or transferring your balance to a card with a 0% introductory APR.
