Profit margins: gross, operating and net margin explained

A profit margin is a slice of revenue expressed as a percentage: how many cents of each sales dollar survive a given layer of costs. Revenue tells you how big a business is. Margins tell you how much of that size turns into profit, and where the rest goes.

There are three standard margins, one for each big subtotal on the Income statement: how to read one line by line, with Apple: gross margin (after the direct cost of what was sold), operating margin (after running the business) and net margin (after interest, other items and taxes). Read together, they work like a ladder. Each step down shows one group of costs, so a change in the bottom number can be traced to the rung where it began.

This page computes all three for Apple Inc. over fiscal 2023 to 2025, splits Apple's gross margin into products and services, and uses the results to show three things every margin reader needs: mix effects, operating leverage, and one-time items that distort a single year.

The margin ladder

Every margin uses revenue (net sales) as its denominator. Only the numerator changes as you walk down the income statement.

• Gross margin measures the economics of the product itself: price against the cost of making or delivering it (cost of goods sold). It is driven by pricing power, component and labor costs, and what is being sold.
• Operating margin subtracts operating expenses, mainly research and development (R&D) and selling, general and administrative costs (SG&A). It measures the business as a whole before financing and taxes. See Operating margin.
• Net margin subtracts everything else: interest, investment gains and losses, and income tax. It is what shareholders actually earned per dollar of sales. See Net profit margin.

Apple, like many companies, labels its gross profit line "gross margin" in dollars. When someone quotes a margin as a percentage, they mean the ratio.

Three years side by side

The top two rungs climbed in both years. The bottom rung dipped and then jumped. A trend that breaks on only one rung is the cue to look at what sits between that rung and the one above it.

Mix: why Apple's gross margin keeps rising

Apple reports cost of sales separately for products and services, so you can compute a gross margin for each. In fiscal 2025 products earned 307,003 − 194,116 = 112,887 of gross profit on 307,003 of sales, a 36.8% margin. Services earned 109,158 − 26,844 = 82,314 on 109,158, a 75.4% margin. Services were 26.2% of sales but 42.2% of gross profit.

A blended margin is a weighted average of its parts, so it moves when the weights move, even if no part changes. Services grew 13.5% in fiscal 2025 and products 4.1%, which moved the services share of sales from 24.6% to 26.2%.

The same split explains fiscal 2023 to 2025 as a whole: services gross margin rose from 70.8% to 75.4% while products stayed near 36.5% to 37.2%. If you see a company's gross margin expand, ask whether it is earning more on each product, or simply selling more of its higher-margin products. The second is real, but it reverses if the mix shifts back. The Economic moats: what protects a company’s profits, and how to test it page looks at what can protect a high-margin line like Apple's services.

Operating leverage

Some costs rise with sales (components, shipping, payment fees). Others are largely fixed over a year (engineers, offices, brand advertising). When sales grow and fixed costs grow more slowly, operating income grows faster than revenue. That effect is operating leverage, and it works in reverse in a downturn.

This is why it pays to read the rungs together. "Operating margin rose" sounds like efficiency. Here it was mostly the gross-margin story, with R&D rising as a share of sales from 8.0% to 8.3%.

One-time items: Apple's fiscal 2024 net margin

In fiscal 2024 Apple's operating margin rose to 31.5%, yet its net margin fell from 25.3% to 24.0%. The rung between them is taxes. Apple recorded a one-time income tax charge of $10,246 million related to the European Commission's State Aid decision, and its effective tax rate jumped to 24.1%, from 14.7% in fiscal 2023.

The lesson is not that the reported figure is wrong. The charge was a real cost paid in cash. It is that a margin trend needs the context of what is recurring. The GAAP vs non-GAAP earnings: how adjusted numbers are built page explains how companies present adjusted numbers and how to check them.

Other margins you will see

• EBITDA margin. Operating income plus depreciation and amortization, divided by revenue. Apple: (133,050 + 11,698) ÷ 416,161 = 34.8%. It strips out non-cash charges for past investment; the EBITDA: what it means, how to calculate it and its limits page covers why that is useful and what it hides.
• Pretax margin. Pretax income ÷ revenue: 132,729 ÷ 416,161 = 31.9% for Apple. It isolates taxes, useful when tax rates swing.
• Free-cash-flow margin. (Operating cash flow − capital expenditure) ÷ revenue: (111,482 − 12,715) ÷ 416,161 = 23.7%. It answers how much cash, not accounting profit, each sales dollar produced. See Free cash flow (FCF): definition, formula and Apple example.
• Contribution margin. Revenue minus variable costs, mostly an internal metric. Public companies rarely report it.

How to read margins well

Compare within an industry. Margins are set by business model. A grocery chain may run on a net margin of a few percent and still be an excellent business because it turns its assets over many times a year; a software firm can earn 30% or more. As a loose rule of thumb, a double-digit operating margin is solid for a hardware maker and a 30%-plus operating margin is unusual. Apple's 32.0% combines both kinds of business. The Stock market sectors and industries: GICS and sector ETFs explained guide explains how peers are grouped.

Look at the trend, not one year. Three to five years show whether a margin is expanding, stable or eroding, and whether any one year is an outlier like fiscal 2024's net margin.

Watch quarterly seasonality. Apple's December quarter carries holiday iPhone sales, so quarterly margins wobble. Compare a quarter with the same quarter a year earlier: in the quarter ended June 27, 2026, gross margin was 50.1% against 46.5% a year before.

Pair margins with growth and returns. A high margin on shrinking sales is a different story from the same margin on growing sales. And a margin says nothing about how much capital it took to earn; that is what Return on equity (ROE): formula, DuPont analysis and pitfalls and Return on invested capital (ROIC): NOPAT, capital and WACC add.

Pitfalls

• Different definitions of cost of sales. Some companies put depreciation, shipping or customer support above the gross-profit line and some below it, so gross margins are not always comparable across firms. Read the notes.
• Stock-based compensation. It is a real expense spread across cost of sales, R&D and SG&A under US GAAP. Adjusted margins that add it back look better than the GAAP ones.
• Revenue that isn't comparable. Agents that report revenue net of what they pass on (marketplaces, travel sites) show high margins on small revenue; principals show low margins on big revenue.
• Averaging percentages. To combine segments or years, add the dollars and divide; don't average the percentages.

How Finabase does it

The Valuation tab has a Profitability group with Gross Margin, Operating Margin and Net Margin, each as a small chart over ten fiscal years. The figures come from the data provider (FMP) on an annual basis, so they can differ by a tenth of a point from a hand calculation, and a quarter in progress isn't included.

The Financials tab gives the raw lines: Total Revenue, Cost of Revenue, Gross Profit, Operating Expenses, R&D, SG&A, Operating Income and Net Income, annual or quarterly. Its "Revenue & Expenses" card draws one period's income statement as a flow from revenue to net income, and its tooltips show gross and net margin. Click any line to chart its history. The summary page's Key statistics shows a trailing-twelve-month "Profit margin" from the data provider. Finabase's screener doesn't filter on margins.

Frequently asked questions

What is a good profit margin?

There is no single good number: it depends on the industry. Compare a company with its own history and with direct peers. A few percent can be healthy for a retailer; software and services companies often run far higher.

What is the difference between gross margin and net margin?

Gross margin subtracts only the direct cost of what was sold. Net margin subtracts every cost, including operating expenses, interest and taxes. Apple's fiscal 2025 gross margin was 46.9% and its net margin 26.9%.

Why did Apple's net margin fall in fiscal 2024?

Because of a one-time $10.2 billion income tax charge tied to the European Commission's State Aid decision. Apple's operating margin rose that year; without the charge its net margin would have been about 26.6%.

Is EBITDA margin better than operating margin?

Neither is better; they answer different questions. EBITDA margin ignores depreciation, so it flatters capital-heavy businesses. Operating margin charges for the wear on past investment, which is usually the fairer comparison.

Summary

Profit margins turn the income statement into percentages of revenue: gross margin for the product, operating margin for the business, net margin for the owners. Apple's fiscal 2025 ladder of 46.9%, 32.0% and 26.9% shows a business whose blended margins are rising mostly because high-margin services are a growing share of sales, with operating income growing faster than revenue. Read the rungs together, over several years, against peers in the same industry, and always check whether a jump or a dip comes from the business or from a one-time item like Apple's fiscal 2024 tax charge.
