You make payments every month. But do you know the month you will finally be done? Type in your debts and in seconds you will see your debt-free date, the order to pay them off, and exactly what to pay each month.

The My Plan tab lists every month until you are debt-free: what to pay on each debt and what is left. Gold marks the month a debt disappears, so you can watch your progress coming.

Paying the smallest balance first feels good, but it can cost you hundreds of dollars more in interest. The calculator runs both methods on your numbers and shows you the difference in dollars and months.
