Answer:
WACC = 0.1018 or 10.18%
Step-by-step explanation:
The WACC or Weighted average cost of capital is the cost of a firm's capital structure that can be made of one or all of the following components namely debt, preferred stock and common equity.
The formula to calculate is as follows,
WACC = wD * tD * (1- tax rate) + wP * rP + wE * rE
Where,
- w represents the weight of each component in capital structure
- r represents the cost of each component
- D, P and E represents debt, preferred stock and Common Equity respectively.
Cost of bond = 7%
Cost of preferred stock = 4/40 = 10%
Cost of Common Equity :
25 = 2 / (r - 0.07)
25 * (r - 0.07) = 2
25r - 1.75 = 2
25r = 2 + 1.75
r = 3.75 / 25
r = 0.15 or 15%
WACC = 0.4 * 0.07 * (1 - 0.4) + 0.1 * 0.1 + 0.5 * 0.15
WACC = 0.1018 or 10.18%
