Re = (D1 / P0) + g


Re=Cost of the Equity

D1=Dividend share the next year

P0=Current share price

g=Dividend growth rate

Consider XYZ Co. Currently has a current market share of $10 and just announced a dividend of $0.85 per share, and it is paid the next year. The growth rate of the dividend is 4%. What is the cost of equity calculation?

The cost of equity capital formula used by the cost of equity calculator:

Re = (D1 / P0) + g

Re = (0.85 /10) + 4%

Re =12.5%

The Capital Asset Pricing Model(CAPM) measures and quantifies a relationship between the systematic risk, and expanded Return on Investment.

The Capital Asset Pricing Model(CAPM) has included the risk in the calculations.
The  Capital Asset Pricing Model(CAPM) 



Ra = Expected return on a security

Rrf = Risk-free rate

Ba = Beta of the security

Rm = Expected return of the market

Practical Example:

Consider a company is offering the Risk-free rate (Rrf) of 2% and the Expected return of market (Rm) 3%. The beta of the security(Ba) is 4.Then find the Expected return on a security (Ra)?


Expected Rate of Return

Expected Return Ra = Rf + Bi * (Rm – Rf)

= 2 + 4 * (3 − 2)

= 2 + (4 * 1)

Ra= 2 + 4 = 6%

The CAPM cost of equity enables the investors to find the Expected Rate of Return(Ra) and the expected risk.
