Answer:
WACC = 7.2%
Explanation:
<em>Weighted average cost of capital is the average cost of all of the long-term types of finance used by a company weighted according to the that amount of finance used in relation to the total pool of fund</em>
To compute the WACC , we will follow the steps below:
Step 1
<em>Calculate the cost of the individual sources of finance:</em>
Cost of debt = Before-tax deb × (1-T)
= 8% × (1-0.35)
= 5.2%
Cost of equity = (Do(1+g)/Po ) + g
= (0.30 (1+0.07)/ 40) + 0.07
= 7.8%
Step 2
<em>Calculate the market value of the individual sources of finance</em>
Equity = $60 billion
Debt = $20 billion
Step 3
<em>Calculate WACC</em>
= 7.8% × 80 billion = 4.6815
= 5.2% × $ 20 billion = 1.04
Total value of debt and equity = 60 + 20 = $80 billion
WACC = (4.68 + 1.04)/ 80 × 100
= 7.2%
WACC = 7.2%
