Determines the interest rate for an investment in an annuity based on regular payments and the premise of a fixed interest rate.
The Excel RATE function is a financial tool used to calculate the interest rate per period of an investment or loan. It allows users to determine the rate of return that would justify a series of cash flows, providing critical insights for financial planning and investment analysis. The function requires inputs such as the number of periods, payment amount, present value, future value, and a type argument to indicate when payments are due.
