Amortization is the process of gradually paying off a mortgage through regular installments that include both principal (the amount borrowed) and interest (the cost of borrowing). In a fully amortizing loan, each payment is calculated so that the loan will be completely paid off by the end of the term. The most common example is a 30-year fixed-rate mortgage with 360 monthly payments — at the end of 30 years, the balance reaches zero.
What makes amortization interesting — and sometimes surprising to homeowners — is how the split between principal and interest changes over time. In the early years, the vast majority of each payment goes toward interest. For example, on a $350,000 mortgage at 6.5% interest, the first monthly payment of approximately $2,212 would allocate about $1,896 to interest and only $316 to principal. By year 15, the split is roughly equal. By year 25, most of each payment reduces the principal. This front-loading of interest is why making extra principal payments early in the loan term has such a dramatic effect on total interest paid.
An amortization schedule is a table that shows the breakdown of each payment throughout the life of the loan. It lists the payment date, total payment amount, principal portion, interest portion, and remaining balance for every single payment. Reviewing this schedule helps borrowers understand how quickly (or slowly) they are building equity and how much total interest they will pay over the life of the loan.

Not all loans are fully amortizing. Balloon mortgages amortize payments over a long period but require a large lump sum at the end of a shorter term. Interest-only loans require no principal payment during an initial period, after which they convert to fully amortizing payments. Adjustable-rate mortgages may have changing amortization schedules as the rate adjusts. Understanding your loan's amortization structure is essential for financial planning.
At closing, your settlement statement will show your first payment date and the initial principal and interest breakdown. The closing disclosure also includes the total of payments and total interest cost over the full loan term, giving you a clear picture of the loan's true cost.
