Derek Wayne has obtained a 30-year, fixed-rate home loan of $ 100,000 with an annual interest rate of 7.5 percent. Because the loan extends for such a lengthy period, the mortgage(抵押) company calculates a monthly payment that ensures it will get most of its interest back first. Thus in the beginning months, Wayne's principal payment—the amount he pays toward his actual loan—increases extremely slowly.
