Answer:
0.175 or 17.5%
Explanation:
The calculation of the cost of common equity is shown below:-
WACC = Weight of Equity × Cost of Equity + Weight of Debt × ( 1- Tax rate) × Cost of Debt
0.13 = (0.55 × Cost of equity) + ((0.45 × (1 - 0.25) × 0.10)
0.13 = (0.55 × Cost of equity) + 0.045 × 0.75
(0.55 × Cost of equity) = 0.13 - 0.03375
(0.55 × Cost of equity) = 0.09625
Cost of equity = 0.09625 ÷ 0.55
= 0.175
Therefore for computing the cost of equity we simply applied the above formula.
