ROE vs ROA
Return on equity vs return on assets — what each measures and how leverage affects them.
⏱️ ~6 min read
Key Takeaways
- ROE = Net Income ÷ Shareholders' Equity; ROA = Net Income ÷ Total Assets
- ROE measures returns generated for shareholders specifically; ROA measures how efficiently all assets (including those funded by debt) generate profit
- A company can boost ROE by taking on more debt, even if its underlying operations haven't become more efficient
- Comparing both metrics together gives a fuller picture than either alone
Two different questions
Return on equity (ROE) and return on assets (ROA) are both profitability ratios that relate a company's net income to a different base — ROE relates it to shareholders' equity, while ROA relates it to total assets. They answer subtly different questions: ROE asks 'how much profit is the company generating relative to the money shareholders have invested?' while ROA asks 'how much profit is the company generating relative to everything it owns, regardless of how it was funded?'
ROE: return on equity
ROE = Net Income ÷ Shareholders' Equity, often expressed as a percentage. It measures how effectively a company turns shareholders' invested capital into profit.
Example: Calculating ROE
A company has net income of $40 million and shareholders' equity of $200 million.
ROE = $40M ÷ $200M = 20%.
This means the company generated profit equal to 20% of its shareholders' equity over the period.
ROA: return on assets
ROA = Net Income ÷ Total Assets, also typically expressed as a percentage. Because total assets include everything funded by both equity and debt, ROA reflects how efficiently the company's full asset base — however it's financed — is being used to generate profit.
Example: Calculating ROA for the same company
The same company has total assets of $500 million (meaning total liabilities = $500M − $200M = $300M).
ROA = $40M ÷ $500M = 8%.
Notice ROA (8%) is meaningfully lower than ROE (20%) — the gap reflects the role debt plays in this company's capital structure.
Why leverage creates a gap between the two
A company can increase its ROE — without improving its actual operating performance — simply by taking on more debt (which doesn't change net income directly but reduces the equity base ROE is divided by, all else equal, or funds the purchase of more income-generating assets). This is why ROE alone can sometimes overstate how 'efficient' a business is, if a large part of its returns are driven by leverage rather than operational performance.
ROA is less affected by capital structure since it's measured against total assets regardless of how they're financed — making it useful for comparing the underlying efficiency of companies with very different debt levels.
Comparing the two together
A large gap between ROE and ROA (high ROE, much lower ROA) suggests a company is using significant leverage — which can amplify returns in good times but also amplify losses and risk in difficult times. A smaller gap suggests the company relies less on debt to generate its returns.
As with most ratios, ROE and ROA are most informative when compared across time for the same company, and against similar companies in the same industry — since 'normal' leverage levels and asset intensity vary significantly by industry (for example, banks and capital-intensive manufacturers naturally look very different from asset-light service businesses).
Frequently Asked Questions
Is a higher ROE always better?+
Not necessarily — a very high ROE driven primarily by heavy debt can indicate higher financial risk, not just efficiency. Looking at ROA and the debt-to-equity ratio alongside ROE provides important context.
Why might ROA be very low for some industries (like banks)?+
Banks and other financial institutions hold enormous total assets (like loans and securities) relative to their equity, which mechanically results in lower ROA figures compared to non-financial companies — this is a structural feature of the industry, not necessarily a sign of poor performance, and is why banks are often evaluated using different metrics.
Can ROE or ROA be negative?+
Yes — if net income is negative (the company reported a loss), both ROE and ROA would be negative, reflecting that the company's equity or asset base shrank in value-generating terms over that period.
