Calculating a cumulative discount factor is a fundamental technique for evaluating the present value of future cash flows. A discount factor represents the ratio of the present value of a unit of currency at a future date to its present value, indicating the time value of money.
In capital budgeting, the cumulative discount factor plays a significant role. It allows businesses to compare projects with different cash flow patterns and timeframes, facilitating informed investment decisions. Historically, the development of discounted cash flow analysis in the mid-20th century marked a major advancement in financial planning and evaluation.
