The weighted average cost of capital (WACC) is calculated using the firm's target capital structure together with its after-tax cost of long-term debt, after-tax cost of short-term debt, cost of preferred stock, and cost of common equity. WACC = Weighted average cost of capital = Wara(1-T) + Wsta(1-T)rstd + Wps ps +Ws T's A firm's target capital structure consists of the following capital structure. Using the relevant costs calculated previously, what is the firm's weighted average cost of capital?

The market value of the notes payable is equal to the book value. Existing long term bonds have a maturity of 15 years and 10% semi-annual coupon (par of $1,000) that is currently traded at $1,200. 2. The common stock price is $31 per share. There are 60 million shares outstanding, for a total market value of equity of $31(60) = $1,860 million. 3. The preferred stock price is $100 per share. There are 1 million shares outstanding, for a total market value of preferred of $100(1) = $100 million.
