2. Cost of Equity: The cost of equity is the return that investors require to invest in the company’s stock.

Calculating the Weighted Average Cost of Capital (WACC)

����=(��+�×��)+(��+�×��×(1−�))WACC=(E+DE​×Re​)+(E+DD​×Rd​×(1−T))

Where:

• �E = Market value of equity
• �D = Market value of debt
• ��Re​ = Cost of equity
