Return on Equity Calculator
Solve the standard ROE relation for any of its three unknowns — return on equity, net income, or shareholders' equity — with step-by-step math, a scaled equity schematic, and the full 3-step DuPont decomposition (margin × turnover × leverage).
ROE is the return on shareholders' money
Return on equity measures how much profit a company generates for every dollar of shareholders' capital. It is the single most-watched profitability metric for equity investors because it directly answers the question they care about: for every dollar of my money the company is using, how much profit is it producing? A high ROE means the company is a good steward of capital; a low or negative ROE signals problems with profitability, efficiency, or capital allocation.
The 3-step DuPont decomposition
ROE can be decomposed into three independent drivers: net profit margin (NI / Revenue), asset turnover (Revenue / Total Assets), and equity multiplier (Total Assets / Equity). ROE is exactly the product of the three. This reveals whether returns come from profitability (high margin), efficiency (high turnover), or leverage (high equity multiplier). A bank runs on very high leverage, a software company on high margin, a supermarket on high turnover. Same headline ROE, completely different operating models.
Leverage inflates ROE — and risk
Because the equity multiplier is part of the DuPont identity, a company can boost ROE simply by taking on more debt. This works when the returns on assets exceed the after-tax cost of debt, but it also magnifies losses when things go wrong. Two companies with identical ROAs can have very different ROEs — and very different risk profiles. Whenever you see an unusually high ROE, the first thing to check is the equity multiplier: if it is high, the returns are being driven by leverage rather than operational excellence.
ROE and ROA tell different stories
Return on assets measures profit relative to all assets; return on equity measures profit relative to shareholders' capital alone. When ROE is much higher than ROA, leverage is doing the work. When the two are close, the company has little debt relative to its asset base. Analysts always look at the two together: ROA strips out leverage and shows pure operating efficiency; ROE shows what shareholders actually earn. Both numbers matter, and the gap between them is itself informative.
How to Use This Calculator
The ROE relation links three quantities: net income, shareholders' equity, and the return ratio itself. Pick which one you want the tool to solve, then fill in the other two.
1. Choose what to solve for
Pick ROE %, Net Income, or Equity. The calculator rearranges the formula automatically for whichever variable you choose and locks that field.
2. Match the period across all inputs
Net income and shareholders' equity must cover the same period — both annual, both quarterly, or both monthly. Never mix an annual net income with a quarterly balance sheet.
3. Use average equity, not just ending
The standard formula uses average shareholders' equity — (beginning + ending) ÷ 2 — which smooths out share issuances, buybacks and retained-earnings changes during the period. In Advanced mode you can enter both balances and apply the average with one click.
4. Read the result and verdict
The result card shows the solved value plus a colour-coded verdict from loss-making through low, moderate, healthy, strong, and exceptional — always read it against your industry's norms.
5. Check the schematic
Two scaled bars show net income and shareholders' equity side by side, with the resulting ROE placed on a −20% to +60% gauge below.
6. Switch to Advanced for DuPont
Advanced mode adds begin/end equity with one-click averaging, optional revenue and total assets for the full 3-step DuPont decomposition, a second chart, sensitivity, and fifteen companion metrics.

What Does Return on Equity Measure?
Return on equity (ROE) measures how much profit a company generates for every dollar of shareholders' capital. It is calculated by dividing net income by average shareholders' equity and expressing the result as a percentage. ROE is the single most-watched profitability metric for equity investors because it directly answers the question they care about: for every dollar of owners' money the company is using, how much profit is it producing?
Because shareholders' equity is what remains after all liabilities are subtracted from assets, ROE is a return on the residual claim. Debt holders are paid first, and whatever is left over belongs to shareholders — so ROE captures the return on the riskiest, most residual layer of the capital structure. That is why ROE is typically higher than ROA for leveraged companies, and why the gap between the two ratios is itself informative.
ROE can be decomposed into three multiplicative drivers using the DuPont identity: net profit margin × asset turnover × equity multiplier. This reveals whether returns come from profitability (high margin), efficiency (high turnover), or leverage (high multiplier). Two companies with identical ROEs can be running completely different business models, and the decomposition shows you which lever each one is pulling.
The Return on Equity Formula
The defining relationship is:
Rearranged to solve for the other two unknowns:
Shareholders' Equity = Net Income / (ROE / 100)
Average equity is normally calculated as:
The 3-step DuPont decomposition splits ROE into three multiplicative components:
Net Profit Margin = NI / Revenue × 100
Asset Turnover = Revenue / Total Assets
Equity Multiplier = Total Assets / Equity
Expanded, this simplifies back to the base ROE formula:
ROE Variables
| Symbol | Meaning | Notes |
|---|---|---|
| NI | Net income after tax | Subtract preferred dividends to get income to common |
| Equity | Average shareholders' equity | (Beginning + Ending) ÷ 2; can be negative in distress |
| ROE | Return on equity | Profit per dollar of shareholders' capital |
| Revenue | Net sales for the period | Used for the DuPont decomposition |
| Assets | Total assets | Used for the equity multiplier |
| Net margin | NI / Revenue | Profitability driver |
| Asset turnover | Revenue / Total Assets | Efficiency driver |
| Equity multiplier | Total Assets / Equity | Leverage driver |
How Each Variable Affects the Result
ROE is linear in net income and inversely proportional to shareholders' equity. Doubling net income doubles ROE at the same equity base. Doubling the equity base halves ROE at the same income level. Both relationships are direct: there is no hidden compounding in the base formula. But shareholders' equity is itself a moving target — it grows when the company retains earnings and shrinks when it buys back stock or pays dividends — so ROE naturally drifts even when the underlying business is stable.
The 3-step DuPont decomposition makes the drivers explicit. A company with a 5% net margin, 2× asset turnover and 2× equity multiplier has a 20% ROE (5% × 2 × 2 = 20%). The same 20% ROE can be achieved by a company with a 20% margin, 1× turnover, and 1× multiplier (asset-light, no debt, high profitability). Both are equally "profitable" by ROE, but they are entirely different businesses with entirely different risk profiles.
The most important caution about ROE is that leverage inflates it. A company can boost ROE by taking on debt, even without improving operations. That works when returns on assets exceed the after-tax cost of debt, but it magnifies losses when the cycle turns. Whenever you see an unusually high ROE — say, above 40% — the first thing to check is the equity multiplier. If the multiplier is high, the returns are being driven by leverage rather than by operational excellence. High ROE is not always a good sign if it comes from a stretched balance sheet.
Return on Equity Calculation Examples
ROE = (10,000,000 / 50,000,000) × 100 = 20.00%
NI = 20 / 100 × 50,000,000 = 10,000,000
Equity = 10,000,000 / (20 / 100) = 50,000,000
Average = (45,000,000 + 55,000,000) / 2 = 50,000,000
Net margin = 10,000,000 / 200,000,000 = 5.00%
Asset turnover = 200,000,000 / 150,000,000 = 1.333×
Equity multiplier = 150,000,000 / 50,000,000 = 3.000×
ROE = 5.00% × 1.333 × 3.000 = 20.00%
Frequently Asked Questions
Return on equity (ROE) measures how much profit a company generates relative to the shareholders' equity on its balance sheet. It is calculated as net income divided by average shareholders' equity, expressed as a percentage. ROE is the headline profitability metric for equity investors because it directly shows how productively the company is using the capital that shareholders have contributed or that has accumulated through retained earnings.
ROE measures profit relative to shareholders' equity only; ROA measures profit relative to all assets (both debt- and equity-financed). ROE is higher than ROA for any company with debt, because debt magnifies returns to the equity layer. That leverage effect can make a weak business look strong on ROE. The gap between the two ratios — the equity multiplier — tells you how much leverage is contributing to the return. Both numbers matter: ROA shows pure operating efficiency, ROE shows what shareholders actually earn.
The DuPont decomposition breaks ROE into three multiplicative components: net profit margin (NI / Revenue), asset turnover (Revenue / Total Assets), and equity multiplier (Total Assets / Equity). ROE is exactly the product of the three. This reveals whether a company's returns come from profitability (high margin), efficiency (high turnover), or leverage (high multiplier). A bank, a supermarket, and a software company might all have 20% ROE, but for entirely different reasons — the DuPont analysis shows you which lever each one is pulling.
It depends on the industry and on how the ROE is being generated. The S&P 500 median has historically been around 15–20%. Banks typically run 8–15%, utilities 8–12%, consumer staples 20–35%, software 15–30%, and exceptional asset-light compounders 30%+ or even 100%+ — but the last category often reflects a very small equity base (from buybacks) rather than genuine operational excellence. The right benchmark is the sector median, and the quality of the ROE depends on whether it is driven by margin, turnover, or leverage.
Two main reasons. First, leverage: a company with high debt has a small equity base relative to its assets, so the denominator shrinks and ROE rises. Second, buybacks: when a company repurchases its own shares, shareholders' equity falls — sometimes dramatically — and ROE mechanically rises even if the underlying business has not changed. Both effects can push ROE to 100% or more in mature, cash-generative companies. Always check the equity multiplier and the trend in the share count before treating a high ROE as a sign of excellence.
Yes. A negative ROE means the company lost money over the period — net income was negative. This is common for early-stage companies, cyclical businesses during downturns, and companies in restructuring. Less obviously, ROE can also appear negative when both net income and equity are negative — a company with negative equity (accumulated losses or heavy buybacks) that also loses money will show a mathematically positive ROE that is analytically meaningless. Always check the sign of both inputs, not just the ratio.
Use average shareholders' equity — normally (beginning + ending) ÷ 2. This smooths out share issuances, buybacks, and retained-earnings changes during the period. Using ending equity alone is a shortcut that can distort the ratio, especially if the company raised capital or repurchased shares during the year. Some analysts use an even more refined measure, averaging quarterly or monthly equity balances, which is more accurate but requires more data.
There are three paths, and they map directly to the DuPont decomposition. First, improve the margin: raise prices, cut costs, or shift the mix toward higher-margin offerings. Second, improve asset turnover: generate more revenue from the same asset base by tightening inventory, collecting receivables faster, or using equipment more intensively. Third, use leverage more efficiently: some debt can boost ROE when returns on assets exceed the after-tax cost of debt, but this also increases risk and should be used cautiously. The right path depends on your starting position and risk tolerance.

What it means
Return on equity (ROE) is a key profitability metric that shows how much profit a company generates with the money invested by shareholders. It is calculated by dividing net income by average shareholders’ equity. A high ROE indicates efficient use of equity capital. It is widely used to compare companies within the same industry, to evaluate management performance, and in the DuPont analysis to break down into components. Understanding ROE is essential for investors to assess the profitability and growth potential of a company.

Common mistakes
- ROE: Return on equity – net income divided by shareholders’ equity.
- Net income: The profit after all expenses and taxes.
- Shareholders’ equity: Average equity over the period – often uses ending or average.
- Interpretation: Measures how effectively the company uses equity to generate profit.
- DuPont analysis: ROE can be decomposed into three components – not just the formula.
Applications
Return on Equity (ROE) measures the net income generated by a company relative to its shareholders' equity, indicating how effectively management uses equity capital to generate profits. It is a key profitability metric for investors and analysts. A high ROE suggests efficient use of equity, but it may also result from high leverage. By calculating ROE, investors can compare management performance across companies and industries. ROE is also used in the DuPont analysis to break down the drivers of profitability. Understanding ROE helps investors assess the quality of earnings and the sustainability of dividends. It is essential for equity valuation and portfolio management.
