Equity 70% 18.40% 12,88%
Debt 30% 6.40% 1,92%
Total 100% 14.80%
Calculation of Cost of Equity
The details available allow us to use the Capital Asset Pricing Model to find the Cost of Equity.
Cost of Equity = Risk Free Rate + Beta × Risk Premium
=3.00%+ 1.40×11.00%
= 18.40%
Calculation of Cost of Debt
We use the after tax Cost of Debt as follows :
Cost of Debt = Market Interest Rate × (1-tax rate)
= 8% × (1-0.20)
= 6.40%
