Amortization schedule

Your amortization period is the total number of years you have to pay off your mortgage.

When you sign on for a mortgage, you agree to pay the principal amount and the interest over the life of the mortgage. Your interest rate is applied to your principal amount, and as you pay down your principal amount, the amount you pay in interest changes. Amortization means that at the beginning of your mortgage, a big percentage of your payment is applied to interest. With each subsequent payment, you pay more toward your principal amount and less toward interest.
