What Is a Good ROE?

Return on equity (ROE) measures how much profit a company generates for every dollar of shareholder capital. A company earning $150 million on $1 billion of equity has an ROE of 15%. As a general benchmark, 15–20% is considered good for US large-caps, and consistently above 20% is strong.

The critical caveat comes early here: debt inflates ROE. A company can raise the number without becoming any better at its business, which is why ROE should never be read alone.

How ROE is calculated

ROE = Net income ÷ Shareholder equity

Shareholder equity is total assets minus total liabilities — the book value of what owners actually own. Both figures come from the financial statements.

A worked example. A company earns $150 million with $1 billion of equity:

$150,000,000 ÷ $1,000,000,000 = 15% ROE

Some analysts use average equity across the year rather than the year-end figure, which matters for companies that issued or bought back a lot of stock. As with every other metric here, check the convention before comparing across sources.

ROE, ROA and ROI

Blackowl's Key Statistics shows three return measures, and they answer different questions:

Measure	Denominator	What it asks
ROE	Shareholder equity	Return on what owners put in
ROA	Total assets	Return on everything the business uses
ROI	Invested capital	Return on all capital, debt included

The gap between ROE and ROA is the leverage tell. ROA counts assets funded by debt; ROE does not. A company with 25% ROE and 4% ROA is producing that return largely on borrowed money. One with 25% ROE and 18% ROA is producing it from the business.

What is a good ROE?

ROE	Typical reading
Below 10%	Weak — capital is not working hard
10–15%	Adequate
15–20%	Good — the usual benchmark
Above 20%	Strong, if it is sustained and not leverage-driven
Above 40%	Investigate. Often buybacks, debt or a distorted equity base

Sector matters as much as it does for profit margins. Software and consumer brands run structurally high ROE because they need few assets. Utilities and heavy industry run lower because they must fund enormous asset bases. Comparing across those groups tells you little.

The trend beats the level. ROE holding above 15% for a decade says far more than one excellent year, which may reflect a one-off gain rather than the business.

Where ROE misleads

This metric has more failure modes than most, and they all run in the same direction — flattering.

Debt inflates it. Equity is the denominator. Borrowing to buy back stock shrinks equity and raises ROE with no operational improvement whatsoever. This is the single most important thing to know about the number. Always read ROE beside the debt load and ROA.

Buybacks shrink the denominator. The same mechanism as with EPS, and it compounds: buybacks reduce equity directly, so sustained repurchases can lift ROE for years while the underlying business is flat.

Write-downs create absurd ROE. A large impairment reduces equity. The following year's ROE can look spectacular precisely because the company destroyed capital.

Negative equity breaks it entirely. Companies with heavy buybacks or accumulated losses can carry negative shareholder equity, which makes ROE meaningless or bizarrely negative. Screeners usually blank it.

It ignores what you pay. A company can have superb ROE and still be a poor investment at the wrong P/E ratio. ROE describes the business, not the price of the shares.

Accounting equity is not market value. Book value reflects historical cost. For asset-light businesses whose value is brand or software, equity can be small enough to make ROE look extraordinary.

How to read it properly

1. Check ROE alongside ROA. A wide gap means leverage.
2. Check the debt level directly — ROE says nothing about it.
3. Look at five years, not one.
4. Compare within the sector.
5. Confirm the earnings are real with free cash flow.

That sequence is a specific case of the broader order in how to research stocks — establish the business, then the profit, then whether it is real, then the price.

See ROE on real companies

Key Statistics on each stock page shows ROE, ROA and ROI together:

• NVDA · AAPL · MSFT · GOOGL · AMZN · META · TSLA

Read ROE against ROA on the same page. Where ROE is far higher, the difference is leverage — and that is exactly the check this metric requires.
