Formula for calculating WACC:

WACC = (Weight of Equity X Cost of Equity) + (Weight of Preferred Stock X

Cost of Preferred Stock) + [Weight of debt X Cost of Debt (1 - Tax)]

Here we substitute the values as per the question :-

Weight of Equity = 45% = 0.45

Cost of Equity = 17.73% = 0.1773

Weight of Preferred Stock = 14% = 0.14

Cost of Preferred Stock = 15.89% = 0.098

Weight of debt = 41% = 0.41

Cost of Debt = 13.46% = 0.1346

1 - Tax = 1 - 40 = 60% = 0.60

WACC = (Weight of Equity X Cost of Equity) + (Weight of Preferred Stock X

Cost of Preferred Stock) + [Weight of debt X Cost of Debt (1 - Tax)]

WACC = (0.45 X 0.1773) + (0.14 X 0.1589) + (0.41 X 0.1346 X 0.60)

= 0.08 + 0.02 + 0.03

= 0.13

= 13 %

Therefore Big Brothers, Inc.  WACC is = 13 %.
