A tool designed to compute the periodic payments required when a borrower is only paying the interest accruing on a revolving line of credit. This financial instrument allows borrowers to access funds up to a pre-approved limit, and initially, payments cover only the interest charges, not the principal amount borrowed. For example, if an individual has a $10,000 line of credit with a 6% annual interest rate, the calculation determines the monthly payment required to satisfy the $50 interest charge, without reducing the $10,000 principal.
Such a computation mechanism is vital for managing cash flow and short-term financial planning. It provides borrowers with flexibility by reducing initial payment burdens, making it particularly useful for individuals or businesses experiencing temporary revenue constraints or those seeking to leverage funds for investments or expenses with anticipated near-term returns. Historically, these arrangements gained popularity as a means to facilitate access to credit, although their potential risks, such as the eventual need to repay the entire principal balance, necessitate careful financial consideration.
