Please explain why the WAACC could not be calculated using the interest rate (8.4%) as the cost of debt and the 4.5% interest on deposit account as the cost of equity? I am a litte confused as to why the cost of capital was used.
The overall cost of capital is the WAAC. Besides, I don’t think you can work out your own WAAC without knowing the market values of debt and equity and the cost of equity.
