The Profitability Ratios Calculator computes core profitability ratios from revenue, cost, operating income, net income, assets, and equity. Enter those line items, and the Profitability Ratios Calculator returns gross margin, operating margin, net margin, return on assets, and return on equity as percentages so profit efficiency and capital return appear together.
Margins answer how much of each sales dollar remains at each profit layer. ROA and ROE answer how much net income was earned on assets and on equity. Together they describe operating performance and how financing and asset base interact with that profit.

Calculate key profitability ratios
The Profitability Ratios Calculator calculates key profitability ratios by dividing each profit measure by revenue, assets, or equity and then multiplying by 100. Those ratios turn raw dollar amounts into comparable percentages across companies and reporting periods of different size.
Use matching periods: annual net income with average or year-end assets and equity from the same reporting window. Mixing a quarterly profit with annual assets distorts ROA and ROE. The Profitability Ratios Calculator applies the inputs as entered; state whether assets and equity are period-end or averages when comparing to published benchmarks.
One-time gains, write-downs, and tax events move net margin and ROE sharply. Read footnotes before treating a single-year spike as the new normal. When comparing two years, restate both on the same revenue and capital definitions so a classification change is not mistaken for an operating improvement.
Calculate the net and gross margins
The Profitability Ratios Calculator calculates gross and net margins from gross profit and net income against revenue. Gross margin shows what remains after cost of goods sold; net margin shows what remains after all expenses, interest, and taxes in the net income figure used.
Gross margin = (gross profit / revenue) x 100. Net margin = (net income / revenue) x 100. Example: revenue $100,000, cost of goods sold $60,000, gross profit $40,000, gross margin 40%. If net income is $20,000 on that same $100,000 revenue, net margin is 20%. The gap between 40% and 20% is operating expenses, interest, taxes, and other items below gross profit.
Gross margin is useful for product and pricing checks. Net margin is the bottom-line share of sales. The Profitability Ratios Calculator shows both so a strong gross margin is not confused with a strong net result.
Calculate the operating margin
The Profitability Ratios Calculator calculates operating margin as operating income divided by revenue, times 100. Operating margin sits between gross and net: it includes operating expenses but excludes interest and taxes when operating income is defined that way on the statement.
Operating margin = (operating income / revenue) x 100. On $100,000 revenue and $25,000 operating income, operating margin is 25%. A fall from 40% gross margin to 25% operating margin means operating expenses consumed 15 percentage points of sales. A further fall to 20% net margin means interest, tax, or other non-operating items consumed another 5 points in this illustration.
Compare operating margin across peers that use similar operating-income definitions. The Profitability Ratios Calculator does not reclassify statement lines; it divides the operating income entered by revenue.
Calculate return on assets and equity
The Profitability Ratios Calculator calculates return on assets and return on equity from net income against total assets and shareholders' equity. ROA measures profit earned per dollar of assets, while ROE measures profit earned per dollar of owners' equity capital.
ROA = (net income / total assets) x 100. ROE = (net income / shareholders' equity) x 100. On net income of $20,000, assets of $200,000, and equity of $100,000: ROA = 10% and ROE = 20%. ROE exceeds ROA here because equity is half of assets; leverage amplifies return on equity when returns on assets are positive, and it amplifies losses when they are not.
Negative equity or near-zero equity makes ROE unstable or undefined. The Profitability Ratios Calculator should flag non-positive equity rather than invent a huge percentage. For a broader ratio set beyond profitability, the Financial Ratios Calculator on QuickCalculators covers additional families. For margin versus markup detail on a single sale, the Margin Calculator is the focused companion.
Trend matters as much as a single year. A net margin that falls from 20% to 12% while revenue rises can still mean higher dollar profit, yet weaker efficiency. The Profitability Ratios Calculator makes each period's percentages comparable when the same definitions are used every time.
Frequently asked questions
What are profitability ratios?
Profitability ratios measure how much profit a business earns relative to revenue, assets, or equity. The Profitability Ratios Calculator reports gross, operating, and net margins plus ROA and ROE from the inputs entered.
How are gross and net margins calculated?
Gross margin is gross profit divided by revenue, times 100. Net margin is net income divided by revenue, times 100. The Profitability Ratios Calculator shows both. On $40,000 gross profit and $20,000 net income with $100,000 revenue, margins are 40% and 20%.
How is operating margin calculated?
Operating margin is operating income divided by revenue, times 100. The Profitability Ratios Calculator places it between gross and net margin. Operating income of $25,000 on $100,000 revenue is a 25% operating margin.
How are ROA and ROE calculated?
ROA is net income divided by total assets, times 100. ROE is net income divided by equity, times 100. The Profitability Ratios Calculator applies those formulas. Net income of $20,000 on $200,000 assets and $100,000 equity yields 10% ROA and 20% ROE.
Why can ROE be higher than ROA?
ROE can exceed ROA when assets are funded partly with liabilities, so equity is smaller than total assets. The Profitability Ratios Calculator shows both figures. Leverage raises ROE when earnings are positive and hurts ROE when earnings are negative.
How does this relate to the Financial Ratios and Margin calculators?
This page focuses on the profitability family. The Financial Ratios Calculator covers a wider set of ratio groups. The Margin Calculator focuses on margin versus markup for pricing. Cross-link all three on QuickCalculators when moving between statement analysis and price setting.
Do accounting choices affect these ratios?
Yes. Revenue recognition, depreciation methods, one-time items, and lease accounting change the inputs. The Profitability Ratios Calculator divides the numbers entered; quality of those numbers determines quality of the ratios.
Summary
The Profitability Ratios Calculator turns statement inputs into gross, operating, and net margins plus ROA and ROE. On $100,000 revenue, $40,000 gross profit, $25,000 operating income, and $20,000 net income, margins are 40%, 25%, and 20%. The same $20,000 net income on $200,000 assets and $100,000 equity is 10% ROA and 20% ROE.
Margins describe share of sales; ROA and ROE describe return on capital. These results are estimates for information only, not accounting advice.
