Example: Calculating WACC
Given:
- Cost of equity = 10%
- Cost of debt = 8%
- Tax rate = 30%
- Market value of equity = KES 1,000,000
- Market value of debt = KES 500,000
Step 1: Calculate the after-tax cost of debt:
After-tax cost of debt = Cost of debt × (1 - Tax rate)
= 8% × (1 - 0.3)
= 8% × 0.7
= 5.6%
Step 2: Calculate total market value of capital:
Total market value = Market value of equity + Market value of debt
= KES 1,000,000 + KES 500,000
= KES 1,500,000
Step 3: Calculate the weight of equity and debt:
Weight of equity = Market value of equity / Total market value
= 1,000,000 / 1,500,000
= 0.6667
Weight of debt = Market value of debt / Total market value
= 500,000 / 1,500,000
= 0.3333
Step 4: Calculate WACC:
WACC = (Weight of equity × Cost of equity) + (Weight of debt × After-tax cost of debt)
= (0.6667 × 10%) + (0.3333 × 5.6%)
= 0.06667 + 0.01867
= 0.08534 or 8.53%
Thus, the WACC for the firm is approximately 8.53%. This indicates the average rate of return required by the firm's investors.
