# Sustainable Growth Rate Formula

## What is the Sustainable Growth Rate Formula?

Sustainable growth rate (SGR) signifies how much the company can grow sustainably in the future without relying on external capital infusion in the form of debt or equity and is calculated using the return on equity (which is the rate of return on the book value of equity) and multiplying it by the business retention rate (which the proportion of earnings kept back in the business as retained earnings).

• is the percentage of earnings for a period of a company with respect to the equity invested in the company. Return on equity is arrived at by dividing earnings from equity.
• The is the percentage of earnings that the company retains for its use and future growth of the company. The retention amount is the residual amount after the amount paid from earnings as a dividend.
Sustainable growth rate Formula = RR * ROE

Where

• RR= Retention ratio
• ROE= Return on Equity

#### Example #1

Let’s assume some numbers in the table below to calculate the sustainable growth for two companies. Calculate the sustainable growth rate for these two arbitrary companies.

For the calculation of a sustainable growth rate, we need the return on equity of a company and retention ratio, which is calculated by deducting the from the earnings of the company and dividing that numerator by net income available to the shareholders.

Retention ratio for Company A

RR= 1- (dividends paid/earnings)

• Retention ratio for Company A= 1- (1.5/4)= 0.63

Retention Ratio for Company B

• Retention ratio for Company B= 1- (2/5) = 0.60

Therefore the calculation of the Sustainable Growth Rate equation for company A is as follows,

• Sustainable growth for company A = 14%*.63

Sustainable Growth Rate for company A

• Sustainable growth for company A= 8.8%

Therefore the calculation of Sustainable growth rate for company B is as follows,

• Sustainable growth for company B = 10%*0.60

Sustainable Growth Rate for Company B

• Sustainable growth for company B= 6.0%

#### Example #2

Calculate the Sustainable growth rate for Reliance Industries. The table below depicts the dividend, earnings per share, and the return on equity for reliance industries.

Retention Ratio for Reliance Industries

• Retention ratio for Reliance Industries = 1- (6/56) =0.89

Therefore the calculation of the SGR formula is as follows,

• Sustainable growth for Reliance Industries = 12%*.89

The sustainable growth rate for Reliance Industries

• Sustainable growth for Reliance Industries = 11%

The higher the rate of Sustainable growth better it is for the company; the ratio signifies for a company that how much the company can grow sustainably in the future with the number of earnings it is generated with the help of the normal course of business. The ratio for reliance industries signifies that reliance industries are able to grow by 11% on a sustainable basis in the future.

#### Example #3

The table below depicts the dividend, , and the return on equity for Tata Steel.

Retention ratio for Tata Steel

• Retention ratio for Tata Steel = 1- (9.4/75) =.87

Therefore the calculation of the SGR formula is as follow,

• The sustainable growth for Tata Steel = 23%*0.87

The SGR for Tata Steel

• The sustainable growth for Tata Steel = 20%

The higher the rate of SGR better it is for the company; the ratio signifies for a company that how much the company can grow sustainably in the future with the number of earnings it is generated with the help of the normal course of business. The ratio for Tata Steel signifies that Tata Steel is able to grow by 20% on a sustainable basis in the future.

### Relevance and Uses

Sustainable growth is a critical ratio to find out the future prospect of a company. Analysts who analyze the company keep a very close look at the ratio. The ratio is arrived at by using two vital parameters, which the return for the equity shareholders of the company. And the second variable used for calculating the SGR Formula is the retention ratio.

It is desirable to have both a higher ratio for return on equity as that signifies higher earnings on the same level of equity investments and also a higher level of retention ratio. If a company is maintaining a higher level of retention ratio, it signifies that the company has future growth prospects and is confident of generating a higher return with the money it is willing to retain. The reason for which return on equity is used as a variable for the ratio is that it directs towards the operational growth of the company, which is attained without the use of .
