The discount rate is an essential tool in finance that calculates the present value of future cash flows. For instance, to determine the current worth of an investment that returns $1,000 in five years, a discount rate of 5% would be used to calculate its present value today.
Understanding discount rates is significant for rational decision-making in business and personal finance. They aid in comparing investments and evaluating the viability of projects, particularly long-term ones. Historically, the concept of discounting future cash flows has been around for centuries, with roots in the 13th century.
