In general, each project's value will be estimated using a discounted cash flow (DCF) valuation, and the opportunity with the highest value, as measured by the resultant net present value (NPV) will be selected (applied to Corporate Finance by Joel Dean in 1951; see also Fisher separation theorem, John Burr Williams: theory). This requires estimating the size and timing of all of the incremental cash flows resulting from the project. Such future cash flows are then discounted to determine their present value. These present values are then summed, and this sum net of the initial investment outlay is the NPV.
The NPV is greatly affected by the discount rate. Thus, identifying the proper discount rate – often termed, the project "hurdle rate"[5] – is critical to making an appropriate decision. The hurdle rate is the minimum acceptable return on an investment—i.e. the project appropriate discount rate. The hurdle rate should reflect the riskiness of the investment, typically measured by volatility of cash flows, and must take into account the project-relevant financing mix. Managers use models such as the CAPM or the APT to estimate a discount rate appropriate for a particular project, and use the weighted average cost of capital (WACC) to reflect the financing mix selected. (A common error in choosing a discount rate for a project is to apply a WACC that applies to the entire firm. Such an approach may not be appropriate where the risk of a particular project differs markedly from that of the firm's existing portfolio of assets.)
