Cost Of Equity

The cost of equity is the return a company requires to decide if an investment meets capital return requirements. Firms often use it as a capital budgeting threshold for the required rate of return. A firm's cost of equity represents the compensation the market demands in exchange for owning the asset and bearing the risk of ownership. The traditional formula for the cost of equity is the dividend capitalization model and the capital asset pricing model (CAPM). 

Formula:

(Cost of Equity = (dividends per share, for next year/current market value of stock)+growth rate of dividends
