What Is ROE (Return on Equity)? Formula, DuPont and Example
Return on equity (ROE) shows how much profit a company earns on shareholders' money. Learn the formula, the DuPont breakdown and how to read ROE safely.
ROE in 60 seconds
- ROE measures the profit a company earns for each rupee of shareholders' equity.
- Formula: net profit ÷ average shareholders' equity × 100.
- High ROE is good only when it comes from real profitability, not from piling on debt — the DuPont breakdown shows which.
Educational summary — not investment advice.
Return on equity (ROE) tells you how efficiently a company turns the money shareholders have invested — plus the profits it has retained — into more profit. It is one of the first numbers quality-focused investors check.
A company that consistently earns a high ROE with little debt is compounding shareholder wealth quickly. That is the reason ROE features in almost every stock screen.
How is ROE calculated?
| Measure | Formula |
|---|---|
| ROE | Net profit ÷ Average shareholders' equity × 100 |
| DuPont breakdown | Net profit margin × Asset turnover × Equity multiplier |
| Net profit margin | Net profit ÷ Revenue |
| Asset turnover | Revenue ÷ Total assets |
| Equity multiplier | Total assets ÷ Shareholders' equity |
Average equity (opening plus closing, divided by two) is more accurate than a single year-end figure. The DuPont split shows whether ROE is driven by profitability, efficiency or leverage.
ROE example with numbers
| Item | Value |
|---|---|
| Net profit | ₹200 crore |
| Shareholders' equity | ₹1,000 crore |
| ROE | 20% |
| Revenue / Total assets | ₹2,000 crore / ₹2,000 crore |
| Net profit margin | 10% |
| Asset turnover | 1.0x |
| Equity multiplier | 2.0x |
| DuPont check: margin × turnover × multiplier | 20% |
An ROE of 20% looks strong, but the DuPont split shows how it is built: a 10% margin, asset turnover of 1.0x, and leverage of 2.0x. Half of the assets are funded by borrowings and other liabilities — so part of that ROE comes from leverage rather than pure operating strength.
Illustrative figures. Half the assets are funded by others, so part of the 20% ROE comes from leverage.
How to read ROE
- Consistency matters more than one year's figure — look at five to ten years.
- Compare within the sector: capital-light businesses naturally show higher ROE than heavy industry.
- Check debt alongside: a high ROE with a high debt-to-equity ratio carries more risk.
- A very high ROE can also come from a tiny equity base after big losses or buybacks.
Limitations
Because equity is in the denominator, anything that shrinks equity — heavy buybacks, large write-offs, big dividends — lifts ROE without improving the business. Negative equity makes ROE meaningless. Pair it with ROCE, which is not affected by how the company is financed.
What ROE is really telling you
Return on equity answers the question every shareholder should care about: for each rupee that owners have put into the business, and each rupee of profit they have left in it, how many paise of profit does the company generate in a year? A company with an ROE of 18% turns ₹100 of shareholder capital into ₹18 of annual profit.
That is why the ratio matters so much for long-term investors. A business that keeps earning a high return on its equity, and can reinvest its profits at the same rate, compounds shareholders' money quickly. A business with a poor ROE needs ever more capital to grow and struggles to reward its owners however impressive its sales figures look.
Calculating ROE from a company's filings
- Net profit attributable to owners comes from the statement of profit and loss (consolidated for a group).
- Shareholders' equity comes from the balance sheet: share capital plus reserves and surplus, excluding minority interest.
- Use the average of opening and closing equity when you can, since equity changes through the year.
Suppose net profit is ₹240 crore, opening equity is ₹1,000 crore and closing equity is ₹1,200 crore. Average equity is ₹1,100 crore, so ROE = 240 ÷ 1,100 = 21.8%. Using closing equity alone would give 20%, using opening equity 24%; the average gives the fairest picture.
Splitting ROE into its three drivers (DuPont)
Two companies can both show a 20% ROE for entirely different reasons. The DuPont breakdown separates the reasons: ROE = net profit margin × asset turnover × equity multiplier.
| Driver | Company P / Company Q |
|---|---|
| Net profit margin (profit ÷ sales) | 20% / 4% |
| Asset turnover (sales ÷ assets) | 0.5 / 2.5 |
| Equity multiplier (assets ÷ equity) | 2.0 / 2.0 |
| Resulting ROE | 20% × 0.5 × 2.0 = 20% / 4% × 2.5 × 2.0 = 20% |
Company P earns fat margins on relatively few sales per rupee of assets, like a premium branded business. Company Q earns thin margins but turns its assets over fast, like a discount retailer. Both reach 20%. Looking at the drivers shows what the business is and what could go wrong: P is exposed to pricing pressure, Q to any slowdown in volumes.
The leverage trap
The third driver, the equity multiplier, is a polite name for borrowing. Raise debt, spend it on assets, and ROE rises even when the underlying business is no better. A company that finances half its assets with debt has an equity multiplier of 2; if it finances three-quarters with debt, the multiplier is 4.
Take a business earning a 10% return on its total assets. Funded entirely by equity, ROE is 10%. With a multiplier of 2, and ignoring interest for simplicity, ROE is 20%. With a multiplier of 4, it is 40%. The catch is that in a bad year the same leverage works in reverse and can wipe out equity. Always read ROE next to debt-to-equity and interest coverage.
How different sectors look on NSE and BSE
ROE is not comparable across industries, because business models differ so sharply. Broad patterns worth knowing:
- Asset-light businesses — software services, branded consumer goods — can earn high ROEs because they need little capital.
- Capital-intensive sectors — power, infrastructure, steel — tend to have lower ROEs because they must tie up large sums in plants.
- Banks and NBFCs run on leverage by nature. Their ROE is read alongside asset quality (gross and net NPAs), capital adequacy and net interest margin.
- Public sector companies often have different capital structures and dividend policies, which affects equity and therefore ROE.
Compare a company with its sector and with its own history, and give more weight to an ROE that has stayed strong for five to ten years than to one exceptional year.
When ROE misleads
- Shrinking equity. Large buybacks, big dividends or accumulated losses shrink equity and can lift ROE without any improvement in the business.
- One-off profits. A gain from selling an asset inflates net profit and ROE for a year.
- Negative or tiny equity. ROE becomes meaningless, or absurdly high, when equity is close to zero.
- Revalued assets. If assets and reserves are marked up, equity rises and ROE falls without any change in performance.
Test yourself
- Question 1. Net profit ₹150 crore, average equity ₹750 crore. ROE? Answer: 150 ÷ 750 = 20%.
- Question 2. A company has a net margin of 8%, asset turnover of 1.5 and an equity multiplier of 2.5. ROE? Answer: 0.08 × 1.5 × 2.5 = 30%.
- Question 3. If the same company cuts its equity multiplier to 1.5 by repaying debt, and nothing else changes, what is the new ROE? Answer: 0.08 × 1.5 × 1.5 = 18%.
Read ROE with ROCE, which ignores how the company is financed, and with debt-to-equity, which shows how much leverage is behind the number.
On NSE and BSE: what to keep in mind
- ROE norms differ sharply between sectors on NSE and BSE — banks, IT services and FMCG typically sit very differently from power, infrastructure or PSU companies — so compare within the sector.
- Check the filed balance sheet: a jump in ROE after a big write-off, buyback or change in reserves is not a sign of a better business.
- For banks, read ROE together with asset quality (gross and net NPAs) and capital adequacy.
ROE: frequently asked questions
What is a good ROE?
Many investors look for a sustained ROE of 15% or more, but it varies by industry. Consistency over years and low debt matter as much as the number itself.
What is the difference between ROE and ROCE?
ROE measures return on shareholders' money after interest; ROCE measures return on all the capital employed, including debt, before interest. ROCE is better for comparing companies with different debt levels.
Can ROE be too high?
Yes. An unusually high ROE can signal excessive leverage or a shrunken equity base, so always check the debt and how the number is built.

The bottom line
ROE shows how well a company grows shareholders' money. Look for high, steady ROE built on profit margins and efficiency — not on borrowed money.
