Answer:
rE= 0.163333 or 16.3333% rounded off to 16.33%
Step-by-step explanation:
The WACC or weighted average cost of capital is the cost of a firm's capital structure which can contain one or more of the following components namely debt, preferred stock and common equity. The formula to calculate WACC of a firm with only two components including debt and equity is as follows,
WACC = wD * rD * (1 - tax rate) + wE * rE
Where,
- wD and wE represents the weight of debt and common equity respectively.
- rD and rE represents the cost of debt and common equity respectively.
- We take after tax cost of debt (1 - tax rate)
To calculate the cost of equity, we can plug in the values of remaining variables as given in the question in the above formula,
0.122= 0.4 * 0.08 * (1 - 0.25) + 0.6 * rE
0.122 = 0.024 + 0.6 * rE
0.122 - 0.024 = 0.6 * rE
rE = 0.098 / 0.6
rE= 0.163333 or 16.3333% rounded off to 16.33%
