Final answer:
The monthly payment on an installment note typically consists of both principal and interest. This combines the amount borrowed with the cost of borrowing, distributed over the loan period. Understanding the breakdown and paying extra can lead to savings.
Step-by-step explanation:
The agreed-upon monthly payment on an installment note normally consists of principal and interest. The principal is the initial amount of the debt or the amount of the loan that remains unpaid (excluding interest). On top of the principal, interest is charged, which is the cost of borrowing the principal amount. Simple interest is calculated only on the principal amount, not on the accumulated interest.
An installment note payment is calculated to evenly distribute the total amount of the loan, including interest, over the number of months of the loan period. For example, if a $300,000 loan has a 6% annual interest rate, convertible monthly, the monthly payments would cover both the reduction of the principal and the interest for that month.
To understand how payments are structured, one can use the simple interest formula or a loan amortization schedule, which shows the breakdown of each payment into principal and interest components. Paying more than the agreed-upon monthly amount can lead to savings in both time and money paid in interest, as it reduces the principal faster.
