Answer: 8.21%
Step-by-step explanation:
The Weighted Average Cost of Capital(WACC) simply put, is the rate at which a company pays those who have invested in it and financed it be it debt holders or equity holders.
The rates in question are averaged according to the proportion by which the company uses the said capital. This results in the following formula,
WACC= [(Wd*Rd) * (1-Tax) + (We * Re) +(Wp * Rp )]
Where,
Wd is the Weight of debt
We is the weight of common Equity
Wp is the weight of preferred Equity
Rd is the Pre-tax cost of debt
Re is the cost of common Equity
Rp is the cost of Preferred equity.
Note: Sometimes you will be given the After - tax cost of debt. In which case you will not need to include the tax adjustment of (1 - tax).
Calculating,
= [( 70% * 9%) * ( 1 - 30%) + (20% * 14%) + (10% * 10%) ]
= 0.0441 + 0.028 + 0.01
= 0.0821
= 8.21%
