The discount factor formula for Net Present Value (NPV) plays a pivotal role in assessing the time value of money. It determines how future cash flows are discounted to their present-day worth, considering the prevailing interest rates. For instance, a project with cash flows of $1,000 in year 1 and $1,500 in year 2, when discounted at a 10% rate, yield an NPV of $2,174.
This formula holds great relevance in capital budgeting and investment analysis. It enables investors and businesses to make informed choices, prioritize projects, and maximize financial returns. Its historical roots can be traced back to Irving Fisher, who pioneered the concept of “Net Present Worth.”
