Profit Margin Calculator
Compute the profit margin as a percentage of revenue: PM = (Net Profit / Revenue) × 100. Solve for margin, net profit, or revenue — with a live profit-breakdown diagram, margin benchmarks across industries, a revenue-vs-profit chart, and step-by-step algebra.
Profitability per revenue dollar
Margin tells you how many cents of profit each dollar of revenue generates. A 20% margin means $0.20 of net profit per $1.00 of sales. It's a ratio, not an absolute — a small-margin business can still earn huge profits if it turns over massive revenue (think Walmart, Amazon), while a high-margin boutique can be profitable on small revenue.
Margin vs markup — different things
Margin = profit ÷ revenue. Markup = profit ÷ cost. They are NOT the same: a 50% markup equals a 33.3% margin. Confusing them is a classic business error — a retailer who prices at "cost + 50%" and thinks they earned a 50% margin is actually at 33%. Always verify which one is being quoted, especially in pricing negotiations.
Margin compresses with scale in low-margin industries
High-revenue businesses like grocery, fuel retail, and logistics typically operate at 1–5% margins because they compete on price and volume. Software and pharmaceutical companies can sustain 25–40% because the marginal cost of one more customer is nearly zero. Comparing margins across industries without context is misleading.
Margin does not equal cash flow
A company can be "profitable" on paper but still run out of cash — for example, if revenue is booked but payments arrive 90 days later while suppliers require cash up front. Margin measures accounting profitability over a period, not liquidity. Also, one-time items (asset sales, tax credits, litigation) can distort margins from the underlying operating performance.

Typical Profit Margins by Industry
Net profit margins, approximate ranges for publicly traded companies in each sector.
| Industry | Typical margin | Range | Notes |
|---|---|---|---|
| Grocery / supermarkets | 1 – 3% | 1.0 – 3.0 | Volume business; razor-thin margins |
| Airlines | 2 – 6% | -5 – 10 | Highly cyclical; fuel-sensitive |
| Retail (apparel, general) | 2 – 6% | 1 – 10 | Depends heavily on brand strength |
| Restaurants | 3 – 9% | 0 – 15 | Food cost and labour dominate |
| Manufacturing | 8 – 15% | 5 – 20 | Capital-intensive; economies of scale |
| Banks / financial | 15 – 30% | 10 – 35 | Leveraged returns; interest spread |
| Pharmaceuticals | 15 – 30% | 10 – 40 | Patent-protected pricing power |
| Software (SaaS) | 15 – 40% | 0 – 50 | High gross margin, big R&D spend |
| Consumer staples | 8 – 15% | 5 – 20 | Brand-driven steady margins |
| Real estate (REITs) | 20 – 40% | 15 – 45 | Depends on leverage and segment |
| Tobacco | 25 – 40% | 20 – 45 | Very high margins, high taxes |
| Oil & gas (integrated) | 5 – 15% | -20 – 25 | Extremely commodity-cycle sensitive |
Frequently Asked Questions
Profit margin is net profit expressed as a percentage of revenue: PM = (Net Profit / Revenue) × 100. It tells you how many cents of profit the business keeps for every dollar of sales. A 15% margin means $0.15 of profit per $1.00 of revenue. It is the single most quoted indicator of a company's profitability per unit of sales, but it must be interpreted within its industry context — grocery stores average 1–3%, while software companies average 20–40%.
Margin and markup both express profit, but against different bases. Margin = Profit / Revenue. Markup = Profit / Cost. Because cost and revenue differ, the two percentages are always different — and margin is always lower than markup for the same transaction. A product sold at $100 that cost $70 to make has a 30% margin ($30/$100) but a 42.9% markup ($30/$70). The conversion formulas are: Margin = Markup/(100+Markup) × 100, and Markup = Margin/(100−Margin) × 100. Confusing them is one of the most common pricing errors in small business.
Yes — a negative profit margin means the business is losing money on every dollar of revenue. If revenue is $100,000 and net profit is −$10,000, the margin is −10%. This is common for early-stage startups (investing heavily for growth), cyclical industries during downturns (airlines, oil & gas in 2020), and any company with fixed costs that can't be cut fast enough when sales fall. A sustained negative margin eventually bankrupts the company unless it's funded by outside capital.
There is no single answer — it depends entirely on the industry and the stage of the business. A useful rule of thumb for mature companies: below 5% is thin, 5–10% is average for many sectors, 10–20% is healthy, and above 20% is excellent. But a 3% margin grocery chain (like Kroger) can be a successful, stable business, while a 3% margin software company would be in trouble. Compare against direct competitors and against the company's own historical trend, not against an abstract benchmark.
Since margin = (Revenue − Costs) / Revenue, you can improve it by increasing revenue without proportionally increasing costs, or by cutting costs without losing revenue. In practice: (1) raise prices — often the fastest lever; (2) reduce COGS through better supplier terms or scale; (3) improve product mix — shift sales toward higher-margin items; (4) cut operating expenses — renegotiate rent, software, insurance; (5) improve productivity — same output with less labour. Each lever has trade-offs — raising prices may lose customers, cutting costs may reduce quality — so the improvement is a strategic, not arithmetic, decision.

What it means
Profit margin is a profitability ratio that shows the percentage of revenue that a company keeps as profit after paying all expenses. It is a key indicator of financial health and operational efficiency. Different margins exist: gross margin, operating margin, and net profit margin. A higher margin means more profit per dollar of sales. Profit margins are used to compare companies within the same industry, to assess pricing strategies, and to evaluate cost control. Understanding profit margins is essential for business owners, investors, and financial analysts to evaluate performance and sustainability.

Common mistakes
- Net profit: Revenue minus all expenses (including taxes and interest).
- Revenue: Total sales or income.
- Profit margin: The percentage of revenue that is profit – higher is better.
- Net vs. gross: Gross margin is different (excludes only COGS) – do not confuse.
- Industry comparison: Profit margins vary widely by industry.
Applications
Profit margin is the percentage of revenue that remains as net profit after all expenses are deducted. It measures the overall profitability and efficiency of a company. Investors, analysts, and managers use profit margin to evaluate performance, to compare companies within an industry, and to track trends over time. A high profit margin indicates strong cost control and pricing power, while a low margin may signal competitive pressure or operational inefficiency. By analysing profit margin, stakeholders can identify areas for cost reduction and revenue enhancement. This metric is a key component of financial statement analysis and is essential for strategic decision‑making and valuation.
