More about this sustainable growth rate calculator so you can better understand how to use this solver: The sustainable growth rate of a firm depends on the retention (plowback) ratio \((RR)\) and the return on equity \((ROE)\)

How do you calculate the sustainable growth rate?

Mathematically, the way you calculate the sustainable growth rate is by using the following formula:

\[ g = \displaystyle \frac{ROE \times b}{1 - ROE \times b}\]

What does sustainable growth mean?

The sustainable growth rate corresponds to the growth rate a firm can endure without increasing its level of leverage. One of the key decisions the management of a firm needs to take is the level of leverage to engage. And the sustainable growth rate shows a realistic growth rate which will no jeopardize the aimed leverage level.

What is an appropriate growth rate?

Realistic and sustainable growth rates will strongly depend on many internal factors (capital structure, management style, etc) and external factor (industry, macroeconomic levels), so there is not one rate that is good for all firms.
