Sustainable Growth Rate Calculator
Business growth is a crucial aspect of long-term success, but expanding too quickly without proper financial backing can lead to overleveraging and collapse. That’s why the Sustainable Growth Rate (SGR) is a vital metric for companies and investors alike. It reflects the maximum rate at which a company can grow its sales, earnings, and dividends without raising additional equity or increasing financial leverage.
The Sustainable Growth Rate Calculator helps analysts, business owners, students, and investors quickly assess how fast a company can grow organically, using its own resources. This metric plays an important role in financial planning, budgeting, and investment decision-making.
Formula
The Sustainable Growth Rate is calculated using the following formula:
SGR = ROE × Retention Ratio
Where:
- ROE (Return on Equity) is the net income divided by shareholders’ equity.
- Retention Ratio is the proportion of earnings retained in the business (not paid out as dividends).
In percentage terms:
SGR (%) = (ROE % × Retention Ratio %) / 100
Example:
If ROE is 20% and the retention ratio is 60%,
SGR = (20 × 60) / 100 = 12%
This means the business can sustainably grow at 12% annually without needing external financing.
How to Use the Sustainable Growth Rate Calculator
Using this calculator is very straightforward:
- Enter Return on Equity (ROE %) – This is typically found in financial reports or calculated as Net Income ÷ Equity.
- Enter Retention Ratio (%) – This is the percentage of net income not paid out as dividends (i.e., retained earnings ÷ net income).
- Click “Calculate” – The calculator computes and displays the SGR instantly.
This tool is perfect for business owners, CFOs, analysts, and even business students evaluating company financials.
Example Calculation
Let’s assume:
- ROE = 15%
- Retention Ratio = 50%
Then,
SGR = 15 × 50 / 100 = 7.5%
So, the business can grow its revenue, assets, and equity base at a rate of 7.5% annually, as long as it maintains the same profitability and dividend policy.
FAQs About Sustainable Growth Rate Calculator
1. What is a good sustainable growth rate?
It depends on the industry. Typically, 5–15% is considered healthy, reflecting strong internal reinvestment capacity.
2. Can a company grow faster than its SGR?
Yes, but only by taking on external funding like debt or issuing new equity.
3. What happens if a company grows faster than its SGR?
It may face liquidity issues, overleverage, or declining financial stability due to reliance on external financing.
4. What is the retention ratio?
It’s the portion of net income that is retained in the business after dividends are paid. It equals 1 − dividend payout ratio.
5. Is high ROE always good for SGR?
Not necessarily. High ROE with low retention limits SGR. Both ROE and retention need to be balanced.
6. How is ROE calculated?
ROE = Net Income ÷ Shareholders’ Equity
7. How can I increase my SGR?
Improve ROE by increasing profitability or equity efficiency, or raise the retention ratio by cutting dividends.
8. Is SGR useful for startups?
Yes. Though they may not have stable ROE or dividend policies, understanding potential sustainable growth is still valuable.
9. What if my SGR is negative?
It may indicate negative ROE or a situation where the company is not profitable—possibly a warning sign.
10. How does SGR relate to dividend policy?
Higher dividends lower the retention ratio, which in turn reduces the sustainable growth rate.
11. Should I compare SGR across industries?
Not directly. Capital-intensive industries often have lower SGRs. Compare companies within the same sector.
12. Can this calculator be used for multi-year projections?
Yes, but you’d need to ensure consistent ROE and retention assumptions across periods.
13. Is this formula valid in inflationary environments?
Yes, but inflation may affect ROE and earnings growth projections, impacting SGR realism.
14. Does SGR account for leverage or debt?
No. SGR assumes internal equity financing only. Growing faster often requires borrowing or issuing equity.
15. How does SGR affect valuation?
It influences discounted cash flow (DCF) models and investor expectations around organic growth.
16. Is a higher SGR always better?
Not necessarily. High SGR must be supported by actual profitability and reinvestment opportunities.
17. What’s the difference between SGR and actual growth rate?
SGR is the theoretical maximum growth rate with internal resources. Actual growth can be higher or lower.
18. What if ROE is zero?
Then SGR is also zero, meaning the business is not generating return on equity and cannot grow without external capital.
19. What role does equity dilution play in SGR?
SGR doesn’t consider dilution. Issuing new equity changes the capital structure, affecting both ROE and funding capacity.
20. Can SGR help in credit analysis?
Yes. It indicates the company’s capacity to grow without increasing debt—important for lenders evaluating creditworthiness.
Conclusion
The Sustainable Growth Rate Calculator offers a quick and effective way to understand how much a business can grow organically without seeking external financing.

Whether you’re a financial analyst conducting due diligence, a business owner planning reinvestment, or an investor evaluating a company’s fundamentals, SGR is a crucial tool in your toolkit. With this simple calculator, you can move beyond static financial reports and into dynamic growth forecasting.
