Sustainable Growth Rate Calculator

Our sustainable growth rate calculator will help you find the sustainable growth rate (SGR) for any company you wish. This metric will help you assess and compare the growth rates of different companies.

This article will explain what the sustainable growth rate is and how to calculate it using the sustainable growth rate formula. Furthermore, we will help you understand this concept by showing you some practical examples.

The sustainable growth rate (SGR) is defined as the maximum growth rate a company can achieve without getting funding from equity and debt. The sustainable growth rate consists of a company's retention rate multiplied by its returns on equity. Mathematically, it is understood as the the value the company can generate with the amount of money it retains.

The SGR formula is most commonly used in various valuation models, such as the dividend discount model (DDM), discounted cash flow model, etc. Hence, it is crucial for us to understand the underlying meaning of this concept.

Let's look at Company Alpha, which contains the following information, as an example explaining the SGR formula:

• Name: Company Alpha
• Net income: $2,000,000
• Dividends paid: $1,000,000
• Shareholders' equity: $10,000,000

The SGR calculation requires 3 steps:

1. Calculate the retention ratio.

   The retention ratio is the number of earnings the company retains after paying out its dividends. We can calculate it using the formula below:

   retention ratio = 1 − dividends paid / net income

   Thus, the retention ratio of Company Alpha is 1 − $1,000,000 / $2,000,000 = 50%.

   You can use our retention ratio calculator for this calculation.

2. Calculate the return on equity (ROE).

   The next step is to calculate the ROE using the formula below:

   ROE = net income / shareholders' equity

   With this formula, the Company Alpha's ROE is $2,000,000 / $10,000,000 = 20%.

   You can also use our return on equity calculator for the calculation.

3. Calculate the sustainable growth rate (SGR).

   The SGR can be calculated using the sustainable growth rate formula:

   SGR = retention ratio × ROE

   Hence, Company Alpha's SGR is 50% × 20% = 10%.

Remember that you can always use our sustainable growth rate calculator to quickly obtain the same result.

Now that we have got the calculation out of the way and learned what SGR meaning is, let's talk about some insights when applying this metric:

• It is difficult for companies to maintain a high sustainable growth rate as they need to make investment to grow. For instance, companies often need to spend millions in research and development to discover new products. This can significantly impact the company's ROE, hence affecting the SGR. Moreover, changes in economic conditions can also affect the sustainable growth rate.

• Furthermore, you might want to pay extra attention to a company's financial leverage when analyzing its sustainable growth rate. This is because some companies may increase their financial leverage with the sole purpose of propping up their ROE, thus increasing their sustainable growth rate. This is considered a negative signal, as the SGR is not sustainable under these circumstances.
