What Is Profit Margin?
Profit margin is the percentage of revenue a business keeps as profit. If a company sells $1 million of goods and ends up with $100,000 of profit, its profit margin is 10%: it keeps 10 cents of every dollar of sales.
Margins let you compare businesses of very different sizes. A corner shop and a global retailer can’t be compared on total profit, but they can be compared on how much of each sale turns into profit. Margins also show trends: a business whose sales are growing but whose margins are shrinking may be buying growth by cutting prices or letting costs run ahead.
There isn’t just one margin. Depending on which costs you subtract, you get gross, operating or net margin, and each answers a different question.
The Three Main Types of Profit Margin
The three margins follow the income statement from top to bottom. The US Securities and Exchange Commission’s beginners’ guide describes the order.1 Revenue minus the cost of sales gives gross profit. Subtract operating expenses and depreciation to get operating income, then interest and income tax to reach net income, the “bottom line”.1
| Margin | Formula | What it tells you |
|---|---|---|
| Gross margin | (Revenue − cost of goods sold) ÷ revenue | How profitable the product itself is, before running costs |
| Operating margin | Operating income ÷ revenue | How well the whole business is run day to day |
| Net margin | Net income ÷ revenue | What is left for owners after every cost, interest and tax |
The SEC’s guide defines operating margin in exactly this way, as income from operations divided by net revenues, usually expressed as a percentage.1
A Worked Example: Calculating Margins for a Bakery
Here is how the three margins work for an illustrative bakery with $500,000 of sales in a year.
| Line | Amount | Margin |
|---|---|---|
| Revenue (sales) | $500,000 | |
| − Cost of goods sold (flour, butter, packaging, bakers’ wages) | $300,000 | |
| = Gross profit | $200,000 | 40% |
| − Operating expenses (rent, staff, marketing, utilities) | $120,000 | |
| − Depreciation (ovens and fittings) | $10,000 | |
| = Operating profit | $70,000 | 14% |
| − Interest on a bank loan | $5,000 | |
| − Income tax at 25% | $16,250 | |
| = Net profit | $48,750 | 9.75% |
For every $1 a customer spends, the bakery keeps 40 cents after paying for ingredients, 14 cents after paying to run the shop, and about 10 cents after interest and tax. This is an illustration: the figures and tax rate are made up, not a guide to any real business or tax system.
What Is a Good Profit Margin?
There is no single “good” margin: it depends heavily on the industry. Businesses that sell high volumes of everyday goods usually run on thin margins, while businesses with low costs per extra sale, like software, can earn much more.
Professor Aswath Damodaran of NYU Stern publishes margin data for US industries every year. His January 2026 figures show how wide the range is:2
| Industry (US, Jan 2026) | Gross margin | Operating margin (pre-tax) | Net margin |
|---|---|---|---|
| Software (system and application) | 71.7% | 33.0% | 25.5% |
| Restaurants and dining | 32.2% | 15.8% | 9.4% |
| General retail | 33.2% | 6.8% | 5.6% |
| Grocery and food retail | 26.3% | 2.3% | 1.3% |
| Auto and truck makers | 10.4% | 2.3% | 1.3% |
| All US companies | 37.8% | 12.8% | 9.7% |
These are averages across many companies, so individual businesses can sit well above or below them.2 A grocery chain with a 3% net margin may be doing very well for its industry, while a software company at 3% would be struggling. Always compare a business with its own past and with direct competitors, not with businesses in other industries.
Margin vs. Markup: A Common Mix-Up
Margin and markup use the same numbers but different bases, and confusing them can lead to underpricing. Margin is profit as a share of the selling price. Markup is profit as a share of the cost.
| Calculation | Result | |
|---|---|---|
| Item costs | $6 | |
| Item sells for | $10 | |
| Gross margin | ($10 − $6) ÷ $10 | 40% |
| Markup | ($10 − $6) ÷ $6 | 67% |
If an owner wants a 40% margin but adds only a 40% markup to cost, the item sells for $8.40, and the actual margin is just 29%. A quick rule: to hit a target margin, divide cost by (1 − the margin). For a 40% margin on a $6 item, that is $6 ÷ 0.6 = $10.
Profit Isn’t the Same as Cash
A business can show healthy margins and still run out of money. See why cash flow decides survival.
Read: What Is Cash Flow? →Why Small Changes Make a Big Difference
Because many costs are fixed, a small change in price or cost can move net profit a lot. Rent, salaries and loan repayments don’t change with each sale, so extra revenue from a price rise flows almost straight to profit.
Take the bakery again. If it raises prices by 5% and sells the same number of items, revenue rises to $525,000 while its costs stay the same. Net profit rises from $48,750 to $67,500, an increase of about 38%, and net margin rises from 9.75% to about 12.9%.
The same leverage works in reverse: a 5% fall in prices, or a jump in ingredient costs, can wipe out a large part of profit. In practice a price rise may also lose some customers, so businesses test changes carefully. This is also why rising costs from inflation or new tariffs can squeeze margins quickly if prices can’t follow.
Contribution Margin and Break-Even
Contribution margin shows how much each sale adds towards fixed costs and profit. It splits costs into two kinds: variable costs, which rise with every item sold (ingredients, packaging, card fees), and fixed costs, which stay the same whatever you sell (rent, salaries, insurance).
Suppose the bakery’s average item sells for $4 and its variable cost is $2.40. Each sale contributes $1.60, a 40% contribution margin. If its fixed costs are $130,000 a year, it needs $130,000 ÷ 0.40 = $325,000 of sales just to break even. Every dollar of sales above that adds 40 cents of profit before interest and tax.
Knowing the break-even point turns margins into a practical target: how many items a day, how many customers a week. It also shows how sensitive the business is. If variable costs rise to $2.80, the contribution margin falls to 30% and the break-even point jumps to about $433,000 of sales. These figures are an illustration, not a benchmark.
Reading Margin Trends: Warning Signs
A single year’s margin tells you little; the direction over several years tells you much more. Watch for these patterns when reading a company’s results:
- Falling gross margin. Input costs are rising faster than prices, or the company is discounting to win sales.
- Rising revenue, flat profit. Growth is being bought with spending that isn’t paying back yet, or ever.
- Net margin far above operating margin. Often a one-off gain, such as selling a building, rather than a better business.
- Margins much higher than every competitor. Either a real advantage or accounting worth checking closely.
Read the management discussion in the annual report for the reasons behind any big change, and compare its explanation with what competitors report for the same period.
How Businesses Improve Their Margins
There are only three levers: charge more, spend less to make each item, or spend less to run the business. In practice:
- Raise prices where customers value the product enough, ideally backed by better quality or service.
- Change the product mix towards higher-margin products and away from low-margin ones.
- Negotiate with suppliers or buy in larger quantities to cut the cost of goods.
- Reduce waste in production, stock and returns.
- Control overheads such as rent, software subscriptions and unused services.
- Build an advantage that gives pricing power; our guide to competitive advantage explains how lasting advantages protect margins.
Margins Across Different Business Models
The way a business makes money largely sets the margins it can earn. Three common patterns:
- Volume businesses, such as supermarkets and discount retailers, sell huge quantities at thin margins. They win on efficiency, buying power and keeping stock moving.
- Service businesses, such as agencies and consultancies, have few materials to buy, so gross margins look high, but staff costs land in operating expenses and pull operating margin down.
- Software and digital products cost a lot to build but very little to sell one more copy, so once fixed costs are covered, margins can be very high.
Neither high nor low margins are good or bad in themselves. A low-margin business can be very valuable if it sells enough and turns its stock quickly; a high-margin business can still fail if it doesn’t sell enough to cover its fixed costs. Our guide to business models explains how these choices fit together.
Setting Prices From a Target Margin
Working back from the margin you need is safer than adding a markup by habit. Start with the full cost of the item, decide the gross margin your business needs to cover running costs and leave a profit, then divide the cost by one minus that margin.
- Cost per item: $6.
- Target gross margin: 40%.
- Price = $6 ÷ (1 − 0.40) = $10.
- Check the price against what competitors charge and what customers will pay.
If the market won’t accept $10, the answer isn’t always a lower price: it may be a cheaper way to make the item, a different product, or a different customer group.
Profit Margin vs. Cash Flow
A healthy margin doesn’t guarantee a business has cash in the bank. Profit is counted when a sale is made, but cash arrives when the customer pays, which can be weeks or months later. A business can be profitable on paper and still fail to pay its bills.
Timing matters too. A business that pays suppliers in 30 days but waits 90 days for customers to pay must fund the gap itself, and the faster it grows, the bigger that gap becomes. That is why owners and investors read margins alongside the cash flow statement. Our explainer on cash flow shows how the two differ and why profitable companies sometimes go broke.
Where to Find a Company’s Margins
For a listed company, the numbers you need are in its annual report. In the US, the annual report filed with the SEC is the Form 10-K. Investor.gov explains that its audited financial statements, including the income statement, appear in Item 8, while Item 7, management’s discussion and analysis, explains the results and trends in management’s own words.3
- Find revenue, cost of goods sold (or cost of sales), operating income and net income on the income statement.
- Divide each profit figure by revenue to get the margin.
- Repeat for three to five years to see the trend.
- Compare with two or three direct competitors.
Many financial websites calculate margins for you. Working them out from the filing yourself helps you spot one-off items, such as a large asset sale, that can make a single year look better or worse than it really was.
Key Terms Explained
These are the terms you will see most often on an income statement.
| Term | What it means |
|---|---|
| Revenue | Total income from sales, also called the top line. |
| Cost of goods sold (COGS) | The direct cost of making or buying what was sold. |
| Gross profit | Revenue minus cost of goods sold. |
| Operating income | Gross profit minus running costs and depreciation. |
| Net income | Profit after every cost, interest and tax: the bottom line. |
| Markup | Profit as a percentage of cost rather than of price. |
The Bottom Line
Profit margin shows how much of each sale a business keeps. Gross margin judges the product, operating margin the running of the business, and net margin what is left for owners. Compare margins within an industry and over time, watch out for the margin-versus-markup trap, and remember that profit and cash are not the same thing.

Frequently Asked Questions
Divide profit by revenue and multiply by 100. For example, $50,000 of net profit on $500,000 of sales is a 10% net profit margin.
Gross margin subtracts only the direct cost of what was sold. Net margin subtracts every cost, including rent, salaries, interest and tax, so it is always lower.
It depends on the industry. Grocery and food retail in the US averaged about 1.3% net margin in January 2026, while software averaged about 25%, so compare with businesses like yours.
No. Margin is profit divided by the selling price; markup is profit divided by the cost. A $6 item sold for $10 has a 40% margin but a 67% markup.
Yes. A high gross margin can be wiped out by high running costs, interest or tax, leaving a net loss. A profitable company can also run out of cash if customers pay slowly.
In its annual report. For US listed companies, the income statement is in Item 8 of the Form 10-K filed with the SEC.
