**What is Return on Equity?**

Return on Equity is a method to calculate the financial position of a company.

It is used to compare the company’s performance with the market and to check whether the money invested by the shareholders is being managed properly or not.

The formula for calculating the Return to equity is:

**Net Income/Shareholders’ Equity**

Return on Equity can help estimate sustainable growth and dividend growth rates.

- Sustainable Growth Rate: a model derived from ROE is used to measure the stock that may be risky and estimate the future, which is essential to be ahead of their ability.
- Dividend Growth Rate: The Payout ratio is multiplied with the ROE to measure the Dividend Growth rate.

There are two methods by which calculation of the cost of equity is done:

- Dividend Capitalization method: DPS is divided by the CMV, and then GRD is added.

DPS: Dividends per share for next year,

CMV: current market value of stock

GRD: growth rate of dividends

- Capital asset pricing method: E(Ri) = Rf + βi * [E(Rm) – Rf]

E(Ri): Expected return on asset I

Rf: Risk-free rate of return

βi: Beta of asset I

E(Rm): Expected market return

The only limitation Cost of Equity has is that if it is calculated with the Dividend Capitalization Method, the company must pay a dividend.
