A tool to determine the periodic payments and the final lump sum within a financing structure where only the interest accrued on the principal is paid during the loan term, culminating in a single, large repayment of the original loan amount at the end. As an illustration, a borrower might use this tool to compute the monthly interest payments on a mortgage for a specified period, knowing a considerable sum is due upon maturity.
This type of financial instrument offers the advantage of lower initial payments, facilitating affordability during the early stages of the loan. It allows borrowers to potentially leverage assets or income streams that are anticipated to increase over time, thereby enabling them to manage the eventual final payment. Historically, such arrangements have been used in real estate and business financing, providing flexibility in managing cash flow.
