WealthReturn on Equity (ROE): A Canadian Investor's Guide to Measuring Profitability
How to Calculate ROE
The formula is simple:
ROE = Net Income ÷ Shareholders' Equity
Expressed as a percentage, ROE tells you how many dollars of profit the company produces for every dollar shareholders have invested. If a company earns $500 million in net income and has $3 billion in shareholders' equity, its ROE is 500 ÷ 3,000 = 16.7%.
Both figures come from the financial statements: net income from the income statement, and shareholders' equity from the balance sheet. For companies listed on the Toronto Stock Exchange, these are available through the TMX Group website or via SEDAR+ annual filings.
| ROE range | What it generally signals |
|---|---|
| Under 5% | Weak profitability — dig deeper |
| 5% to 10% | Average for some sectors |
| 10% to 15% | Reasonable; often considered acceptable |
| 15% and above | Generally considered strong |
| Very high (e.g., 40%+) | Worth investigating — may signal high leverage |
How to Interpret ROE
There is no universal threshold, but here are some general reference points:
| ROE | General Interpretation |
|---|---|
| Under 5% | Weak profitability — dig deeper |
| 5% to 10% | Average for some sectors |
| 10% to 15% | Reasonable; often considered acceptable |
| 15% and above | Generally considered strong |
| Very high (e.g., 40%+) | Worth investigating — may signal high leverage |
Important caveat: these benchmarks shift significantly by sector. Canada's major banks have historically posted ROEs between 12% and 18% — considered solid in financial services, where balance sheets are structurally leveraged. By contrast, a manufacturer with an 8% ROE may be outperforming its peers. Always compare companies within the same sector.
To complement ROE with another valuation lens, see our guide on the P/E ratio for Canadian stocks.
| Net income | Equity | Debt | Resulting ROE | |
|---|---|---|---|---|
| Company A | $100 million | $800 million | — | 12.5% |
| Company B | $100 million | $400 million | $1 billion | 25% |
Company B's ROE is twice as high — but it carries twice the financial risk.
The Debt Trap: When ROE Misleads
This is the most important limitation to understand. ROE can be artificially inflated by debt — and this catches many investors off guard.
Here's the mechanics: if a company borrows heavily, its shareholders' equity (assets minus liabilities) shrinks. The same net income divided by smaller equity produces a higher ROE — not because the business is more profitable, but because it is more leveraged.
Illustrative example: two companies each earn $100 million in net income. Company A has $800 million in equity (ROE = 12.5%). Company B has $400 million in equity but $1 billion in debt (ROE = 25%). Company B's ROE is twice as high — but it carries twice the financial risk.
Always pair ROE with the debt-to-equity ratio (D/E) or Return on Assets (ROA) to distinguish genuine profitability from financial engineering. Our article on the price-to-book (P/B) ratio also helps put ROE in context.

- Thin net profit margin
- Very high asset turnover
- Return driven by sales volume, not margin
Software company profile
- Opposite pattern: higher margin
- Lower asset turnover
- Return driven by margin, not volume
DuPont Analysis: Unpacking Where ROE Comes From
To understand why a company's ROE is what it is, analysts use the DuPont decomposition:
ROE = Net Profit Margin × Asset Turnover × Financial Leverage
- Net profit margin: how much profit the company keeps on each dollar of sales
- Asset turnover: how efficiently it uses assets to generate revenue
- Financial leverage: how much of the return is driven by debt
Two companies can share the same ROE for entirely different reasons. A grocery chain might have a thin margin but very high asset turnover; a software company might be the opposite. DuPont analysis reveals which driver is actually at work, making it easier to assess the quality and sustainability of the return.
ROE and Canadian Bank Stocks
Canada's Big Six banks are a classic case study for ROE analysis — and a reminder that context matters. Banks are structurally leveraged: they use deposits and borrowings to fund loans and generate returns. A high leverage ratio is baked into their business model, not a red flag.
Over long periods, well-managed Canadian banks have maintained relatively stable and predictable ROEs, which is part of why they tend to trade at a premium to book value. A sustainably high ROE can justify a price-to-book (P/B) ratio above 1, since the market pays up for durable profitability. For more on this, see our guide to Canadian bank stocks.

Using ROE in Your Investment Process
ROE is particularly useful in two scenarios:
- Value investing: identifying companies with consistently strong ROE whose shares appear undervalued relative to peers. See our piece on value vs. growth investing in Canada for more on this approach.
- Sector screening: ranking companies within an industry by ROE to find the most efficient operators.
One important reminder: ROE is one tool in a larger toolkit. It does not replace a full analysis of a company's growth prospects, management quality, competitive position, and broader market conditions. Always review multiple metrics and data sources. If you are unsure how to apply this to your own situation, consider speaking with a registered financial adviser.

Frequently asked questions
What is a good ROE for a Canadian stock?
There is no single benchmark — it depends heavily on the sector. As a general guideline, 15% or above is often considered strong. For Canadian banks, ROEs between 12% and 18% are typical and well-regarded. Always compare companies within the same industry rather than against an absolute number.
Can debt inflate ROE?
Yes, and this is one of the most important traps to watch for. When a company borrows heavily, shareholders' equity shrinks, which mechanically pushes ROE higher — even if actual profitability has not improved. Pair ROE with the debt-to-equity ratio or Return on Assets (ROA) to get a fuller picture.
What is the difference between ROE and ROA?
ROE (Return on Equity) measures profitability relative to shareholders' capital only. ROA (Return on Assets) measures profitability relative to total assets, including debt. A large gap between the two typically signals high financial leverage — the company is relying heavily on borrowed money to boost returns.
Why does sector matter when comparing ROE?
Capital structures and business models vary dramatically across industries. Banks and utilities operate with much higher leverage than tech or mining companies, so their ROEs are naturally different. Comparing a bank's ROE to a miner's tells you nothing useful; always benchmark within a peer group.
What does a negative ROE mean?
A negative ROE means the company posted a net loss. This could be temporary — due to a restructuring, large write-down, or heavy investment phase — or it could reflect deeper structural problems. Look at the trend over several years rather than judging a single quarter or year in isolation.
Where can I find ROE data for Canadian stocks?
Financial statements are available through the TMX Group website (tmx.com), via SEDAR+ annual reports, or through most Canadian brokerage platforms. The OSC's GetSmarterAboutMoney.ca also offers guidance on how to read financial statements and use key ratios.
