AMD‚ the WACC is 10.83%. For Duck Energy‚ the WACC is 2.76% When we calculate those number‚ we need to know the equity and debt of the company which can easily find on yahoo finance. The cost of debt and the corporate tax rate that we calculated are also based on the data from yahoo finance. We made Beta for the companies with 10 year ranges and use it to calculate return of equity. After we got those number‚ we can calculate the WACC.
