What is ROE and how is it interpreted?
Updated June 27, 2026 · DeepTicker
ROE (return on equity) measures how much net profit a company generates for every euro contributed by its shareholders. It's the best-known profitability gauge: a ROE sustained above 15% usually signals a good business, but beware, because debt can inflate it artificially.
What ROE is and why it matters
ROE (Return On Equity) answers the question that matters most to a shareholder: out of every euro I (and the other owners) have put into this company, how much net profit does it return to me each year? If shareholders have contributed €100 and the company generates €18 of net profit, the ROE is 18%. It's essentially the return on your money as an owner of the business.
It's probably the most famous and most cited profitability metric, partly because Warren Buffett has mentioned it many times as a good initial quality filter. The intuition is powerful: a company that year after year generates a ROE of 20% is multiplying its owners' capital at an enviable pace, as long as it reinvests that profit profitably. That's why a high and stable ROE is one of the first signs of a solid business.
But ROE has an enormous trap you should know about before trusting it: debt inflates it. Since the denominator is only equity, a company can raise its ROE simply by replacing equity with debt. Imagine two identical companies that earn the same; the one financed with more debt will have less equity and therefore a higher ROE, even though it isn't a better business, just a riskier one. That's why a ROE of 30% can hide either an exceptional company or a highly leveraged and fragile one.
To unmask this there is the DuPont analysis, which breaks ROE down into three levers: the net margin (how much it earns per euro of sales), the asset turnover (how many sales it generates per euro of assets) and the financial leverage (how much asset it supports per euro of equity). This breakdown tells you where the ROE comes from: from good margins and efficiency (healthy) or from a lot of debt (dangerous). It's one of the most useful tools for not being fooled by a big number.
ROE should always be read together with the level of debt and, above all, alongside ROIC. ROIC measures the return on all the capital (equity and debt) and isn't inflated by leverage. When ROE is much higher than ROIC, the difference is almost always explained by debt. A truly quality company shows a high ROE accompanied by a high ROIC and moderate debt: it earns well without having to gamble.
ROE is also related to the ability to grow. The sustainable growth formula is, simplifying, ROE × retention rate (the portion of profit not paid out as a dividend). A company with a ROE of 20% that reinvests half its profit can grow sustainably at around 10% a year without taking on more debt. This connection between ROE and growth is what explains why businesses with a high return on equity compound so much value over the long term.
How ROE is calculated
ROE = Net profit / Average equity × 100
- · Net profit: the final result for the year, after interest and taxes; what truly belongs to shareholders.
- · Equity: the capital contributed by shareholders plus reserves and profits retained over time.
- · Average equity: the average between equity at the start and end of the period is usually used to smooth one-off movements.
- · × 100: ROE is expressed as a percentage so it reads as an annual return.
Example of ROE
Imagine a consumer company with net profit of €90 million and average equity of €500 million. Its ROE is 90 / 500 = 18%. For every euro contributed by shareholders, the company generates 18 cents of profit a year. At first glance, a profitable business.
Now compare it with a competitor that also earns €90 million but has only €300 million of equity because it finances itself with much more debt. Its ROE comes out to 90 / 300 = 30%, apparently better. But if you look at its ROIC, which includes debt in the capital, you might discover that both have a similar ROIC of 12%: the second isn't a better business, just more leveraged and therefore more fragile in the face of rising rates or a recession. The high ROE was, in part, a debt mirage.
DeepTicker makes this comparison for you: it shows ROE alongside ROIC and the level of debt, and integrates it into the Profitability dimension of the DeepScore, comparing it with the median of the sector. If the consumer sector runs around a ROE of 14%, the first company's 18% would stand out as quality profitability; and seeing the ROIC next to it, you understand that this ROE is healthy and not the result of leverage. You learn by looking.
How to interpret ROE
- →ROE > 15% sustained usually indicates a good business; above 20%, high quality.
- →ROE < 10% is weak; a sustained negative ROE is a viability alarm.
- →If ROE is much higher than ROIC, the difference is almost always explained by debt: be careful.
- →Use the DuPont analysis to see whether the ROE comes from margin and efficiency (healthy) or from leverage (risky).
- →Look at the consistency of ROE over 5-10 years; an isolated one can be noise or the result of a one-off.
- →Combine ROE with the retention rate to estimate sustainable growth (ROE × retention).
Common mistakes with ROE
- ✕Celebrating a high ROE without checking whether it comes from debt instead of business quality.
- ✕Comparing the ROE of companies with very different leverage levels as if they were equivalent.
- ✕Trusting a single year's ROE instead of looking at the historical series.
- ✕Ignoring ROIC alongside ROE, which is what reveals the effect of leverage.
- ✕Forgetting to compare ROE with the median of the sector, since the bar for 'good' varies a lot by industry.
What counts as a good or bad ROE
As a general reference, a ROE below 10% is usually considered weak, between 10% and 15% acceptable, and above 15% good; a ROE sustained above 20% signals a high-quality business. But these ranges are indicative: what matters is comparing it with its sector and checking where that ROE comes from (margin and efficiency versus debt).
A very high ROE, above 40-50%, isn't always good news. Sometimes it reflects an extraordinary business with very few assets (such as a services company), but other times it hides an artificially small equity base due to aggressive buybacks or a lot of debt. It's wise to be wary of extremes and always look at the composition.
A low or negative ROE indicates the company is making poor use of its owners' money, or that it has had losses. It can be temporary (a bad year, an investment not yet maturing) or structural. A negative ROE sustained over time is a serious alarm about the viability of the business.
Why debt inflates ROE (the big trap)
The main trap of ROE is that it only looks at equity in the denominator. Since equity falls when the company finances itself with debt instead of capital, the same profit divided by less equity gives a higher ROE. It's pure arithmetic, not an improvement in the business. That's why comparing the ROE of two companies with very different debt levels can lead you to the wrong conclusions.
The DuPont analysis is the best defense. It breaks ROE down into net margin, asset turnover and leverage. If two companies have the same ROE but one achieves it with a good margin and the other with a lot of leverage, they aren't equal at all: the leveraged one takes on far more risk and its ROE will collapse if things go wrong.
The practical way not to fall into the trap is to look at ROE alongside ROIC and the debt ratio. When ROE far exceeds ROIC, the difference is debt. DeepTicker presents these metrics together precisely so you can see at a glance whether a high ROE is healthy or just leverage disguised as quality.
ROE versus ROIC, ROA and ROCE
The difference between ROE and ROIC is the most relevant: ROE looks only at equity and is inflated by debt, while ROIC measures the return on all the invested capital and is immune to leverage. To judge the real quality of a business, ROIC is more reliable; ROE tells you the return for the shareholder, debt included.
Against ROA (return on assets), ROE is always equal to or greater, because ROA divides by all assets and ROE only by equity. The difference between the two reflects precisely the degree of leverage: the further apart ROE and ROA are, the more debt is in play. Looking at both together is a quick way to gauge financial risk.
ROCE resembles ROIC more than ROE, because it also includes debt in the capital employed, but it uses EBIT before taxes. Overall, the best read is to cross all four: ROE for the shareholder's return, ROIC and ROCE for operating quality free of leverage, and ROA for efficiency on assets. DeepTicker gives you all four so the picture is complete.

What is a good ROE for a company?
As a reference, a ROE above 15% usually indicates a good business and above 20% high quality, as long as it doesn't come from excess debt and is compared with the median of the sector.
Why can a high ROE be misleading?
Because ROE only looks at equity. If the company finances itself with a lot of debt, equity falls and the ROE rises artificially, without the business being any better, just riskier.
What's the difference between ROE and ROIC?
ROE measures the return on equity and is inflated by debt; ROIC measures the return on all the invested capital (equity and debt) and isn't distorted by leverage.
How is ROE calculated?
By dividing the year's net profit by equity (ideally the average for the period) and multiplying by 100 to express it as a percentage.
What does a negative ROE mean?
A negative ROE means the company has had losses or that its equity is negative. It can be a one-off, but sustained over time it's a serious sign of trouble in the business.
What is the DuPont analysis of ROE?
It's a breakdown of ROE into three levers (net margin, asset turnover and leverage) that reveals where the profitability comes from: from efficiency and margins (healthy) or from a lot of debt (risky).
Where can I see a stock's ROE?
In DeepTicker you see the ROE already calculated, historical and compared with its sector for stocks from the US, Europe, the IBEX and China, alongside ROIC and debt to judge whether it's healthy.
