Assume that your company is trying to determine its optimal capital structure, which consists only of

Ratio
Now assume that the company's tax rate is 40 percent, that the company uses the CAPM to
estimate its cost of common equity, Ks, that the risk-free rate is 5 percent and the market risk
premium is 6 percent. Finally assume that if it has no debt its WACC would be equal to its cost of
equity which would be equal to 11 percent (you should now be able to determine its "unlevered
beta," bu).

Given this information, determine the firm's cost of capital if it finances with 40 percent debt and 60
percent equity.
0.30/0.70=0.43
