This amortization schedule is based on the following assumptions:įirst, it should be known that rounding errors occur and, depending on how the lender accumulates these errors, the blended payment (principal plus interest) may vary slightly some months to keep these errors from accumulating or, the accumulated errors are adjusted for at the end of each year or at the final loan payment. In addition to breaking down each payment into interest and principal portions, an amortization schedule also indicates interest paid to date, principal paid to date, and the remaining principal balance on each payment date.Īmortization schedule assumptions Often, the last payment will be a slightly different amount than all earlier payments. The last payment completely pays off the remainder of the loan. The first payment is assumed to take place one full payment period after the loan was taken out, not on the first day (the origination date) of the loan. Increasing balance ( negative amortization)Īmortization schedules run in chronological order.Balloon (amortization payments and large end payment).There are different methods used to develop an amortization schedule. As the loan matures, larger portions go towards paying down the principal. Initially, a large portion of each payment is devoted to interest. An amortization schedule indicates the specific monetary amount put towards interest, as well as the specific amount put towards the principal balance, with each payment. While a portion of every payment is applied towards both the interest and the principal balance of the loan, the exact amount applied to principal each time varies (with the remainder going to interest).

The schedule differentiates the portion of payment that belongs to interest expense from the portion used to close the gap of a discount or premium from the principal after each payment.

The percentage of interest versus principal in each payment is determined in an amortization schedule. A portion of each payment is for interest while the remaining amount is applied towards the principal balance. Amortization refers to the process of paying off a debt (often from a loan or mortgage) over time through regular payments.
