Frequently asked questions
What is NPV?
NPV measures the profitability of an investment by calculating the present value of all future cash flows minus the initial investment.
What discount rate should I use?
Use your required rate of return, cost of capital, or the rate you could earn elsewhere (opportunity cost).
Is positive NPV always good?
A positive NPV means the investment returns more than your discount rate, making it generally worthwhile.
