Credir card minimum payments

If you were only to pay the minimum required payment on your credit card, do you know how much interest you would end up paying before your balance is paid off? Calculate the interest costs and the number of payments (up to a maximum of 600 months, meaning 50 years in some cases!) you will have to make to pay off your balance in its entirety.
Note: other than decimal points, do not enter any other non-numeric characters (commas, letters or dollar signs), as doing so will cause an error in calculation.
