The average home loan interest rate
Amortization schedule
When you take out a mortgage, you agree to pay the principal and interest over the loan’s life. Your interest rate is applied to your balance, and as you pay down your balance, the amount you pay in interest changes.
Amortization means that at the beginning of your loan, a big percentage of your payment is applied to interest. With each subsequent payment, you pay more toward your principal.
