Frequently Asked Questions
We use the formula for the number of periods (n) = log((P - r*B)/P) / log(1+r), where P is monthly payment, r is monthly interest rate (APR/12/100), and B is balance. The result is rounded up to the nearest month.
If your payment is less than or equal to the interest charged in the first month (balance * monthly rate), you will never pay off the debt. The calculator will warn you to increase your payment.
This calculator assumes a fixed APR and fixed monthly payment. Actual credit card interest may compound daily, but this monthly approximation is commonly used for planning.
