What is return on equity (ROE)?
Return on equity (ROE) measures how much profit a company earns for every dollar of shareholders' equity. It answers one question: how hard is the owners' money working? A 20% ROE means the business generates 20 cents of net income a year per dollar that shareholders have invested or left in the company. Analysts, lenders, and investors read it as the headline test of how efficiently a management team turns equity into profit — and it is the figure this return on equity calculator returns the moment you enter net income and equity.
How to calculate return on equity step by step
Calculating ROE takes two numbers and one division. Both come straight from the financial statements, so the work is in reading them correctly, not in the arithmetic.
- Find net income. Take the after-tax profit from the bottom of the income statement for the period — typically a full fiscal year.
- Find shareholders' equity. Read it off the balance sheet (total assets minus total liabilities), or use average equity for a more accurate ratio — see the next section.
- Divide and convert to a percentage. ROE = net income ÷ equity × 100. The calculator above does this live as you type, and adds the DuPont breakdown when you enter revenue and assets.
Average vs. ending shareholders' equity — which to use
Here is a choice most quick explainers skip. Net income is earned across the whole year, but the balance sheet shows equity only at a single instant — the closing date. Dividing a full year of profit by a single-day equity figure mismatches the periods.
The fix analysts use is average shareholders' equity: the start-of-year balance plus the end-of-year balance, divided by two. It smooths out big mid-year changes — a stock buyback, a capital raise, a large dividend — that would otherwise distort the ratio. Use ending equity for a fast, back-of-envelope read; use average equity when equity moved materially during the year.
| Equity base | When to use it | Effect on ROE |
|---|---|---|
| Ending equity | Quick estimate; equity stable through the year | Simple textbook form |
| Average equity | Equity changed materially (buyback, raise, big dividend) | More accurate; matches a full year of profit |

A worked example using the ROE calculator
A company posts $80,000 in net income. It opened the year with $380,000 of shareholders' equity and closed at $420,000. Revenue was $1,000,000 and total assets were $800,000. Here is how the calculator works through it — equity base first, then ROE, then the DuPont check.
Step 1 — Choose the equity base
Equity rose from $380,000 to $420,000, so average equity is the honest base: (380,000 + 420,000) ÷ 2 = $400,000. That is the figure the ROE is measured against.
Step 2 — Divide net income by equity
| Input | Value |
|---|---|
| Net income | $80,000 |
| Beginning equity | $380,000 |
| Ending equity | $420,000 |
| Average equity | $400,000 |
ROE = $80,000 ÷ $400,000 = 0.20.
Step 3 — Confirm it with the DuPont breakdown
Enter revenue ($1,000,000) and total assets ($800,000) and the calculator splits the same 20% into three drivers: net profit margin of 8.0% ($80,000 ÷ $1,000,000), asset turnover of 1.25 ($1,000,000 ÷ $800,000), and an equity multiplier of 2.0 ($800,000 ÷ $400,000). Multiply them: 0.08 × 1.25 × 2.0 = 0.20 — exactly the 20% ROE. The next section explains why that split is so useful.
The DuPont 3-step decomposition of ROE
A single ROE number tells you the result but hides the cause. Two companies can both report 20% ROE for completely different reasons — one through fat margins, the other through heavy borrowing. The DuPont model, developed at the DuPont Corporation in the 1920s, splits ROE into three drivers so you can see what produces the return.
- Net profit margin — how much of each sales dollar survives as profit. The operating and pricing story.
- Asset turnover — how much revenue each dollar of assets generates. The efficiency story.
- Equity multiplier — total assets divided by equity, a direct measure of financial leverage. A multiplier of 2.0 means every $1 of equity supports $2 of assets, funded by $1 of debt.
This is the lever that separates a healthy ROE from a fragile one. A retailer might earn 20% ROE on thin margins but rapid turnover; a software firm on rich margins and slow turnover; a bank on modest margins and a high equity multiplier. The DuPont split tells you which engine is running — and the next section explains why the leverage engine deserves a hard second look.
What is a good return on equity?
There is no single 'good' ROE — it depends on the industry and the era. As a broad rule, an ROE in the 15–20% range is considered healthy, and a sustained 20%+ is strong. The long-run ROE of the S&P 500 has hovered roughly between 10% and 17%, so a figure near the mid-teens is solidly average for a large US company. Compare a company against its own industry, not against the whole market.
| Sector character | Typical ROE range | Why |
|---|---|---|
| Software / consumer brands | 20%+ | High margins, light asset base |
| Broad market (S&P 500) | ~14–17% | Blended large-cap average |
| Industrials / manufacturing | 10–15% | Heavy assets dilute returns |
| Regulated utilities | ~8–12% | Capital-intensive, rate-capped |
Indicative ranges only — always benchmark against direct competitors and the company's own history.
When a high ROE is a warning, not a win
A high ROE looks unambiguously good. It often is not. Because the equity multiplier sits inside the DuPont formula, a company can inflate ROE simply by replacing equity with debt — buying back shares or borrowing heavily. The profit per dollar of equity rises, but only because there are fewer equity dollars, not because the business got better.
Leverage cuts both ways. As long as a company earns more on borrowed money than it pays in interest, debt lifts ROE. But the same leverage magnifies losses in a downturn, and a firm with thin equity has little cushion. That is why a 30% ROE built on an equity multiplier of 5 is far riskier than a 20% ROE built on a multiplier of 1.5.
ROE vs. ROA vs. ROIC
ROE is one of a family of return ratios, and reading them together neutralizes each one's blind spot. The key difference is the denominator: what pool of capital each ratio measures the return against.
| Ratio | Formula | What it measures |
|---|---|---|
| ROE | net income ÷ equity | Return to shareholders — includes the effect of leverage |
| ROA | net income ÷ total assets | Return on the whole asset base — strips leverage out |
| ROIC | after-tax operating profit ÷ invested capital | Return on all capital (debt + equity) put to work |
ROE × (equity ÷ assets) = ROA, so the gap between ROE and ROA is exactly the leverage effect.
A wide gap between ROE and return on assets is the leverage signature. If ROE is 20% but ROA is only 5%, debt is amplifying the return fourfold. Use the financial ratios calculator to compute ROA and the debt-to-equity ratio alongside ROE, and pair this with ROI when you are sizing a single investment rather than a whole company.
Return on equity — frequently asked questions
What does an ROE of 20% mean?
It means the company generated 20 cents of after-tax profit for every dollar of shareholders' equity during the period. In the mid-teens-and-above range, that is a strong result for most industries.
Can return on equity be too high?
Yes. An unusually high ROE often signals heavy debt rather than a great business. Check the equity multiplier and the debt level — if leverage is driving the number, the return carries more risk than the headline suggests.
Why is my ROE negative?
ROE turns negative whenever net income is negative. It is also meaningless when equity itself is zero or negative — common after years of accumulated losses or aggressive buybacks — so the ratio should not be relied on in those cases.
Should I use average or ending equity?
Use average equity when the equity balance changed materially during the year; it matches a full year of profit to a representative equity figure. Ending equity is fine for a quick estimate when equity was stable.
What is the difference between ROE and ROA?
ROE divides profit by equity; ROA divides the same profit by total assets. ROE includes the boost from leverage, while ROA strips it out. A large gap between them tells you how much debt is amplifying shareholder returns.
Sources and methodology

Benchmark ranges are drawn from long-run S&P 500 return-on-equity data and widely cited industry norms. This calculator computes book ROE on the equity base you choose and is for planning and analysis, not a substitute for a CFA or audited financial statements.
