Credit Card Payoff Time Formula

Formula
$$n = \frac{-\log\left(1 – \frac{r \times P}{M}\right)}{\log(1 + r)}$$

Where:

  • $$n$$ = Number of months to pay off the balance
  • $$r$$ = Monthly interest rate (annual rate divided by 12)
  • $$P$$ = Outstanding balance (principal)
  • $$M$$ = Monthly payment amount


The Credit Card Payoff Calculator helps you determine the time needed to eliminate your credit card debt. It calculates the number of months required based on your current balance, monthly payment, and interest rate, allowing you to plan repayment strategies more effectively.
