Key Highlights
- Sustainable growth rate (SGR) is the growth rate a company can achieve without taking additional debt.
- A company can compete, only if its growth rate is strong enough.
- However, a company may face potential issues if its growth rate is very high. It is essential to consider the potential drawbacks of such rapid expansion.
- Combining debt and equity capital can build a balanced approach for long-term growth.
Definition of Sustainable Growth Rate
A sustainable growth rate (SGR) is the growth rate that a business can achieve without taking more debt or equity capital. So, it denotes the pace at which a company may expand by using its existing assets. The term "sustainable growth rate" describes a firm's life cycle. It provides a clear view of the key areas for achieving the desired growth.
SGR works on the basis of certain presumptions. They include the following.
- The company never modifies its single dividend ratio.
- The capital structure of the firm remains steady.
- It is working hard to increase sales.
- The company focuses on products with better profit margins.
- The business is working hard enough to manage its inventory, accounts payable, and accounts receivable.
##Calculating the Sustainable Growth Rate##
Let’s now look at the Sustainable Growth Rate (SGR) formula. However, to understand the SGR formula you need to first know about a few terms. They are as follows.
-
Dividend payout ratio: The percentage of earnings that shareholders receive as dividends per share is the dividend payout ratio. Its formula is dividends per share/earnings per share (EPS).
-
Retention rate (1 - dividend payout ratio): This is the portion of earnings that a business still needs to distribute dividends. In simpler terms, it is the income that the company keeps for itself.
-
ROE: Return on Equity (ROE) measures how much an investor earns based on the company's profits. Its formula is Net income / Total shareholder equity.
The company's financial statement often includes ROE and dividend ratios.
SGR Formula:
So, the formula of SGR is;
Sustainable Growth Rate = Retention Ratio * Return on Equity
Example:
The net income of Company Alpha is Rs. 50,000. Shareholder equity is Rs. 2,00,000, and the dividend payout rate is 15%. Here is how to calculate the company's SGR.
Retention ratio = ( 1 - 0.15) = 0.85 Return on equity = (50,000/2,00,000)= 0.25 So, the SGR = 0.85*0.25 = 0.21
Hence, Company Alpha can achieve a maximum growth rate of 21% without any additional equity or debt financing.
Benefits of SGR
The sustainable growth rate can help a business with the following things.
- Long-term growth planning and cash flow projections
- Borrowing additional funds
- Grow by issuing equity and compensating the equity investors
- Audit its expenditure and profit
- Make strategies for better efficiency
- Manage day-to-day operations like early bill payment
- Ensure financial efficiency and manage receivable and payable accounts
- Plan the financial future by setting goals that won't put them in financial stress
- Help determine the amount of capital for steady growth.
The Drawback of using SGR
Using the SGR to calculate the growth rate is helpful. Yet, it is still not perfect.
-
The averages of a particular sector are the basis for the sustainable growth rate formula. Thus, it might only be valid for some businesses in a specific industry.
-
Three different elements are the basis of the SGR formula. They are retention ratio, dividend payout, and ROE. However, they may or may not correctly reflect the current state of a company's affairs.
Difference Between SGR and PEG Ratio
A measure of a company's potential for growth is the price-to-earnings-growth ratio (PEG) ratio. Here are the key differences between the SGR and PEG
Definition | A measure of the company's growth in relation to its existing capital structure. | A measure of the company's growth in relation to its stock price. |
Purpose | To determine whether a company's stock is overvalued or undervalued. | To determine whether a stock is undervalued or overvalued. |
Formula | (Sales growth + Operating profit margin growth + Equity growth) / 100 | (Price-to-earnings ratio) / (Earnings per share growth rate) |
Interpretation | A higher SGR indicates faster growth. Still, it does not necessarily mean the stock is overvalued or undervalued. | A PEG ratio of less than 1 indicates that the stock may be undervalued, while a PEG ratio of more than 1 indicates that the stock may be overvalued. |
Limitations | The SGR does not take into account the company's debt levels or the quality of its earnings. | The PEG ratio assumes that the company's earnings per share growth rate will remain constant. This may not be the case always. |
Conclusion
One should consider the sustainable growth rate (SGR) while investing in a stock. The SGR represents the expected future growth rate of a company without taking debt. It indicates a company's capacity to expand over time without negative effects on its stakeholders, customers, and employees. A higher SGR indicates that the business is using its earnings to provide high returns on equity. Thus, SGR is a beneficial tool for investors, creditors, rating agencies, and the finance team.
