A mortgage note payable with a fixed interest rate requires the borrower to make installment payments over the term of the loan. Each installment payment includes interest on the unpaid balance of the loan and a payment on the principal. With each installment payment, indicate the effect on the portion allocated to interest expense and the portion allocated to principal.
The Correct Answer and Explanation is:
Each installment payment on a fixed-rate mortgage typically consists of two parts: interest expense and principal repayment. The interest portion is calculated based on the remaining loan balance, while the principal portion reduces the outstanding loan amount. Here’s how the portions change over time:
- Interest Expense: The interest is calculated on the outstanding balance of the loan. In the early stages of the mortgage, the loan balance is higher, so the interest expense is larger. As the borrower makes payments over time, the outstanding balance decreases, and consequently, the interest expense decreases as well. This means the interest portion of each payment is higher at the beginning of the loan term.
- Principal Repayment: As the interest portion decreases, the portion allocated toward the repayment of principal increases. In the initial payments, only a small part of the payment is applied to the principal, as the interest expense is larger. Over time, as the loan balance reduces, the amount going toward the principal increases. This allows the borrower to pay off the loan faster in the later stages.
Effect Over Time:
- In the early years, a greater percentage of the payment goes toward interest due to the higher loan balance. For example, if the monthly payment is $1,000 and the interest expense for the month is $800, only $200 would go toward paying down the principal.
- As the loan balance decreases, in later years, more of the payment is applied to the principal. So, the $1,000 monthly payment might include $300 toward interest and $700 toward principal repayment.
This process is common in amortizing loans, and while the total amount of interest paid over the life of the loan decreases with each payment, the borrower is still obligated to make regular payments that reduce the principal and interest accordingly.
