discounted cash flow

in finance, discounted cash flow (DCF) analysis is a common technique of placing value on a project or company. All of the future cash flows are projected and discounted by using cost of capital to determine their present values (PVs). Adding up all future cash flows, both incoming and outgoing, provides the net present value (NPV).
