Answer:
Risk-free rate = 3.5%
Market risk-premium = 6.9%
Cost of equity (Ke) = ?
Ke = Rf +β(Rm - Rf)
Ke = Rf + Market risk premium
Ke = 3.5 + 6.9
Ke = 10.4%
Cost of debt (Kd) = 5.4%
Market value of debt (D) = 12
Market value of equity (E) = 88
Market value of the company (V) = 100
WACC = Ke(E/) + Kd(D/V)(1-T)
WACC = 10.4(88/100) + 5.4(12/100)(1-0.40)
WACC = 9.152 + 0.3888
WACC = 9.54%
Explanation:
In this case, there is need to calculate cost of equity according to capital asset pricing model, which is risk-free rate plus market risk-premium.
Then, we will calculate the weighted average cost of capital, which equals cost of equity multiplied by the proportion of equity in the capital structure plus after-tax cost of debt multiplied by the proportion of debt in the capital structure. Since the proportion of debt in the capital structure is 12%(12/100), the proportion of equity will be 88%(88/100).
