How to Use This Calculator

To use the credit card payoff calculator:

  3. Specify how much you plan to pay each month in the "Monthly Payment" field.

How the Credit Card Payoff Calculator Works

The calculator uses the following formula to determine your payoff timeline:

Number of Months = -log(1 - (Current Balance × Monthly Interest Rate) / Monthly Payment) / log(1 + Monthly Interest Rate)

Where:

  • Monthly Interest Rate = APR / 1200
  • Total Interest Paid = (Number of Months × Monthly Payment) - Current Balance

This formula accounts for the interest you'll pay on your balance each month while making payments. The calculator assumes you make the same monthly payment throughout the payoff period.

Example Calculation

Let's say you have a credit card balance of $5,000 with a 18% APR, and you plan to pay $300 each month.

The calculator would determine:

  • Monthly Interest Rate = 18% / 1200 = 0.015 (1.5%)
  • Number of Months = -log(1 - (5000 × 0.015) / 300) / log(1.015) ≈ 32 months
  • Total Interest Paid = (32 × 300) - 5000 = $4,600

This means it would take about 32 months to pay off $5,000 at 18% APR with $300 monthly payments, with $4,600 in total interest paid.
