First identify or calculate the capital spending, the operating cash flow, the change in net working capital, and finally the free cash flow to the firm of the project. Free Cash Flows are cash flows available to the firm after stakeholders have been paid (interest and dividends). It is these free cash flows that you find that are discounted at the weighted average cost of capital to calculate the net present value and the internal rate of return.
You will assess whether to make the investment or not. Use your accept-reject rules for the net present value and the internal rate of return.
