The net present value (NPV) of a series of cash flows is found by calculating the present value of each cash flow at the appropriate discount rate and then adding them together.

The net present value is used to compare projects and to evaluate whether or not a project is worthwhile. It assumes that a project comprises a series of cash flows in or out of the business over a number of years.
