This calculator will show you how much time and money you could save by paying off your debts using the 'rollover' method. Using the rollover method, as each smaller debt is paid off, the freed up payment amount is then applied to the next larger debt, and so on until all debts are paid off. As you are about to see, the rollover method can save you a great deal of money in interest charges, and get you debt free in a very short period of time.
