The Cost of Capital: Weighted Average Cost of Capital The firm's target capital structure is the mix of debt,preferred stock, and common equity the firm plans to raise fundsfor its future projects. The target proportions of debt, preferredstock, and common equity, along with the cost of these components,are used to calculate the firm's weighted average cost of capital(WACC). If the firm will not have to issue new common stock, thenthe cost of retained earnings is used in the firm's WACCcalculation. However, if the firm will have to issue new commonstock, the cost of new common stock should be used in the firm'sWACC calculation.
