Mathematically, Cost of shareholder equity can be calculated as follow ;

Cost of Shareholder equity = Risk free rate + (Beta of stock x Market Risk Premium) (a)

Risk free rate or T- bills rate = 4 %

Beta of Stock = 0.80

Market risk Premium = 8 %

By putting the values in equation (a)

Cost of shareholder equity or equity capital = 4 % + 0.80 x 8 %

Cost of equity capital =  10.4 % .
