What Is Amortization (Mortgage)?
Amortization in the context of a mortgage refers to the systematic repayment of a loan through regular, fixed payments that include both principal and interest. In a standard amortizing mortgage, early payments are heavily weighted toward interest, with the principal portion increasing over time as the outstanding balance decreases. For example, in a 30-year fixed-rate mortgage, the first payment might allocate 80% to interest and 20% to principal, while the final payment is almost entirely principal. An amortization schedule shows the breakdown of each payment over the life of the loan. Understanding amortization helps borrowers evaluate the true cost of a mortgage, compare loan terms, and assess the impact of extra principal payments on reducing total interest paid and shortening the loan term.
Amortization (Mortgage) Example
- 1On a $300,000 30-year mortgage at 6.5%, the first monthly payment of $1,896 allocates $1,625 to interest and only $271 to principal.
- 2By making one extra principal payment of $200 per month on a 30-year mortgage, a homeowner can save over $70,000 in interest and pay off the loan 6 years early.
