How to Use This Calculator

Using our credit card repayment calculator is simple. Follow these steps:

Enter your current credit card balance in the "Current Balance" field.
Input your credit card's annual percentage rate (APR) in the "Interest Rate" field.
Specify your minimum monthly payment in the "Minimum Payment" field.
Click the "Calculate" button to generate your payoff timeline.

The calculator will display your estimated payoff date, total interest paid, and a chart showing your balance over time.

Formula Explained

The credit card repayment calculator uses the following formula to estimate your payoff timeline:

Payoff Time (Months) = (log(Minimum Payment) - log(Minimum Payment - (Current Balance × Daily Interest Rate))) / log(1 + Daily Interest Rate)

Where Daily Interest Rate = Annual Interest Rate / 365

This formula calculates how many months it will take to pay off your credit card balance based on your minimum monthly payment and the daily interest rate.

Worked Example

Let's look at an example to see how the calculator works. Suppose you have a credit card balance of $5,000 with an APR of 18% and a minimum monthly payment of $200.

Current Balance: $5,000
Interest Rate: 18%
Minimum Payment: $200

Using the formula, we calculate that it will take approximately 32 months (2 years and 8 months) to pay off this balance, with a total interest payment of $1,200.

Tips for Faster Payoff

Here are some strategies to help you pay off your credit card faster:

Pay more than the minimum: Making larger payments each month will significantly reduce your payoff time and interest costs.
Use the snowball method: Pay off your smallest balances first to build momentum and motivation.
Balance transfer: Consider transferring your balance to a card with a 0% introductory APR to save on interest.
Automate payments: Set up automatic payments to ensure you never miss a due date.
