How it works
NPV = sum of each year's cash flow ÷ (1 + rate)^year − the initial investment. Enter one cash flow per year, separated by commas. A positive NPV means the project earns more than your discount rate. Example: $10,000 invested today with the default cash flows at 8% gives an NPV of about $2,381.
