Capital budgeting involves decisions about whether or not to invest in fixed assets, and it has a major influence on firms' future performances and values. Discounted cash flow analysis is used in capital budgeting, and a key element of this procedure is the discount rate used in the analysis. Capital must be raised to finance fixed assets, and this capital comes from different sources: debt, preferred stock, and common equity. Each of these capital components has a cost, and these cost rates, along with the target proportions of each, are used to calculate the firm's weighted average cost of capital or "WACC."
