Before buying a stock, just seeing profits go up isn’t enough. You have to check if the company can actually grow on its own money. That’s what the Sustainable Growth Rate shows you. It tracks how much profit goes back into the business to keep things moving – without issuing new shares to raise cash.
What Is Sustainable Growth Rate (SGR)?
Sustainable Growth Rate (SGR) is the rate at which a company can grow its business by reinvesting its retained earnings while maintaining its existing financial structure. It depends on the company’s return on equity (ROE) and retention ratio, helping investors assess its potential to sustain growth without issuing new equity shares.
What Is the SGR Formula?
To calculate a company’s Sustainable Growth Rate (SGR), one must look at how much profit the company generates on its equity and what portion of that profit is reinvested into the business. These two factors help estimate the company’s growth capacity.
SGR Formula
SGR = ROE × Retention Ratio
Where,
- ROE = (Net Profit ÷ Beginning Shareholders’ Equity) × 100
- Retention Ratio = 1 − Dividend Payout Ratio
SGR Calculation Example
Suppose ABC Ltd net profit is ₹40 lakh, shareholders’ equity at the beginning of the year is ₹2 crore, and the company pays out 25% of its profit as dividends.
| Particulars | Calculation | Result |
|---|---|---|
| Net Profit | Given | ₹40 lakh |
| Beginning Shareholders’ Equity | Given | ₹2 crore |
| ROE | (40 lakh ÷ 200 lakh) × 100 | 20% |
| Dividend Payout Ratio | Given | 25% |
| Retention Ratio | 100% − 25% | 75% |
| SGR | 20% × 75% | 15% |
In this example, ABC Ltd.’s SGR is 15%. This means that, based on current assumptions, the company can support a growth rate of approximately 15% using its earnings and retained earnings. However, actual growth will also depend on market demand, business performance, and financing requirements.
How to Calculate SGR Using a Company’s Financial Statements
To calculate the Sustainable Growth Rate (SGR) of a listed company, one needs to examine the information regarding net profit, shareholders’ equity, and dividends provided in its annual report. This allows investors to understand what portion of its earnings the company is retaining and the extent to which this can support its profitability growth.
Suppose the following figures are given in the financial statements of ABC Ltd –
| Financial Details | Amount |
|---|---|
| Net Profit | ₹60 lakh |
| Beginning Shareholders’ Equity | ₹3 crore |
| Dividend Payout Ratio | 30% |
Step 1: Calculate Return on Equity (ROE)
ROE = (Net Profit ÷ Beginning Shareholders’ Equity) × 100
ROE = (₹60 lakh ÷ ₹300 lakh) × 100 = 20%
Step 2: Calculate Retention Ratio
Retention Ratio = 100% − Dividend Payout Ratio
Retention Ratio = 100% − 30% = 70%
Step 3: Calculate SGR
SGR = ROE × Retention Ratio
SGR = 20% × 70% = 14%
Based on this calculation, ABC Ltd.’s SGR is 14%. This means that, given its current profitability and dividend policy, the company can support a growth rate of approximately 14%, provided the model’s other assumptions remain valid.
Key Factors That Affect Sustainable Growth Rate
A company’s SGR depends on how much profit it generates, how much of that profit it retains, and how it utilizes funds to run its operations.
1. Return on Equity (ROE)
ROE indicates the profit a company generates using shareholders’ capital. If a company increases its profit by effectively utilizing its equity, its SGR can also rise. However, it is crucial to understand the reason behind an increase in ROE, as high debt levels can also influence this metric.
2. Retention Ratio
When a company keeps its profits to re-invest rather than paying dividends, that’s the retention ratio. Think about it this way a 30% dividend payout leaves 70% in the company’s bank account. Retaining a bigger slice of profits like that gives the SGR a direct lift, as long as nothing else shifts.
3. Profit Margin
The profit left over from every sale plays a massive role in growth. Companies raise margins by either cutting costs or pushing sales up. Whenever profit margins improve, it gives SGR a nice push too assuming other factors don’t pull it down.
4. Asset Turnover Ratio
Some companies expand their business by generating higher sales from their existing assets. The asset turnover ratio helps assess how efficiently a company utilizes its assets. Improved asset utilization can support ROE and, consequently, the SGR.
5. Debt and Financial Leverage
Companies may take on debt to expand operations, but borrowing entails obligations regarding interest payments and loan repayment. While high leverage can impact ROE, it also increases financial risk. Therefore, when evaluating SGR, one must also consider the company’s debt levels and cash flow.
How Should Investors Interpret a Company’s SGR?
To truly understand the meaning of SGR, looking only at its percentage is not enough.
- Compare with the company’s actual growth: If the SGR is 12% but sales are growing at 20%, examine how this growth was achieved. The company might have taken on debt or issued new shares to expand its operations.
- Look at EPS alongside profit: Even if a company’s total profit rises, the profit attributable to each share may not increase at the same pace. Therefore, it is essential to track changes in EPS alongside the SGR.
- Understand the debt burden: If debt is rising rapidly alongside the company’s growth, future interest and repayment obligations could create financial pressure. Check the debt-to-equity ratio and interest coverage ratio to assess this.
- How is the company utilizing its profits?: If the company retains a significant portion of its profits, check the annual report to see if the funds are being spent on new projects, machinery, or business expansion. This provides a better understanding of how retained earnings are being utilized.
- Evaluate the share price independently: SGR indicates a company’s growth capacity, not the fair value of its stock. Consequently, even if a company has a strong SGR, one should not make an investment decision without considering the P/E ratio and current valuation.

Sustainable Growth Rate vs Internal Growth Rate
SGR and IGR both show how much a company can expand using just the money it earns.
| Comparison | Sustainable Growth Rate (SGR) | Internal Growth Rate (IGR) |
|---|---|---|
| Meaning | Growth potential under current financial policies | Growth potential based solely on internal funds |
| External Financing | Debt financing is possible without issuing new equity. | External financing is not used. |
| Main Formula | ROE × Retention Ratio | ROA × Retention Ratio ÷ (1 – ROA × Retention Ratio) |
| Main Focus | Return on equity and financing structure | Return on assets and retained earnings |
| Use in Stock Analysis | It helps in understanding the company’s growth and financing needs. | It helps understand how much the company can grow without external funding. |
Limitations of SGR in Stock Analysis
While SGR provides an indication of a company’s growth potential, it is not appropriate to judge a stock solely based on this figure; there are certain limitations that must be understood.
- No Guarantee of Future Growth: Just having a 15% SGR doesn’t guarantee 15% profit growth year after year. Slower sales, stronger rivals, or bigger bills can easily drag actual growth down.
- Does Not Show the Full Debt Picture: A company might have a good SGR but also carry a heavy debt load. Therefore, one cannot accurately assess its financial position by looking at SGR alone.
- Varies Across Industries: A manufacturing company may need to invest heavily in new machinery and plants, whereas a service company might have different requirements. Consequently, comparing the SGR of companies across different industries should be done with caution.
- Does Not Indicate Share Valuation: SGR reflects a company’s potential growth capacity but does not indicate whether the stock is cheap or expensive at its current price. For that, one must also consider valuation and other financial ratios.
Conclusion
A company’s SGR basically shows if it can keep growing without constantly needing outside money. But honestly, never buy a stock just looking at SGR. You’ve got to check their cash flow, debt, real profits, and what the share price is doing. Looking at everything together is the only real way to figure out if a company is actually a safe investment.

Frequently Asked Questions (FAQs)
What is considered a good Sustainable Growth Rate?
There’s no single number that works for every company. What counts as a good SGR depends on the industry, how profitable the business is, and its overall financial health.
How do you calculate SGR?
It’s pretty simple: just multiply the Return on Equity (ROE) by the retention ratio.
Can SGR turn negative?
Yes. If a company’s ROE drops below zero, the SGR will turn negative too.
What’s the difference between SGR and IGR?
SGR assumes a business can take on some debt while keeping its current capital structure. IGR (Internal Growth Rate), on the other hand, looks only at growth funded strictly by internal cash without any outside debt.
Does a high SGR mean a stock is a solid buy?
Not necessarily. A strong SGR is a good sign, but you still need to check the stock’s valuation, debt load, cash flow, and overall earnings before making a decision.
