The determination of the amount due covering only the cost of borrowing is a fundamental calculation in certain loan structures. It involves multiplying the outstanding principal balance by the stated annual interest rate and then dividing the result by the number of payment periods in a year. For example, a $100,000 loan with a 5% annual interest rate paid monthly would have an interest-only amount of $416.67 ($100,000 * 0.05 / 12). This result represents the portion of the payment that covers solely the cost of borrowing the funds, without reducing the initial amount owed.
Understanding this figure is crucial for borrowers as it provides a clear picture of the cost associated with maintaining the loan and is especially important for those with adjustable-rate mortgages or those planning to refinance in the near future. It allows for better budgeting and financial planning during the initial phase of a loan, especially when seeking lower initial payments. Historically, this type of arrangement has facilitated property acquisition or investment opportunities where cash flow is a primary concern.
