Apple makes money in two main ways. First, it sells physical devices — the iPhone, Mac computers, iPad tablets, Apple Watch, AirPods, and accessories. Most people own one iPhone at a time, so Apple has to keep convincing them to upgrade. Second, it sells services — things like the App Store, Apple Music, Apple TV+, iCloud storage, Apple Pay, and advertising. Services run on top of the devices Apple has already sold, which means every existing iPhone owner is a potential services customer. In 2025, iPhone brought in $209.6 billion in sales, while Services added another $109.2 billion. The two sides of the business feed each other: more devices mean more services customers, and better services make people less likely to switch to a different device. The diagram below traces where the money goes.

Five years of financial data tell a clear story about where Apple's health is actually improving — and where it is not. Revenue grew from $365.8 billion in 2021 to $416.2 billion in 2025, but the path was not straight. Revenue dipped from $394.3 billion in 2022 to $383.3 billion in 2023, then climbed back. That dip matters because it shows this is not a business that automatically grows every year. What has moved steadily in one direction is gross margin — the share of each dollar of revenue that Apple keeps after paying for what it sells.

Gross margin has risen every year for five straight years, from 41.8% in 2021 to 46.9% in 2025. Source: Apple 10-K filings.
The reason gross margin keeps rising is that Services is growing faster than the device business — and Services margins are dramatically higher. In 2025, the Services segment posted a gross margin of 75.4%, while the Products segment came in at 36.8%. As Services gets bigger relative to the whole company, the overall margin rises. Services revenue jumped from $85.2 billion in 2023 to $109.2 billion in 2025 — a $24 billion increase in just two years. That is the financial shift that matters most when reading Apple's numbers.
What is gross margin and why does it matter?
Gross margin is the percentage of revenue left after paying for the direct cost of making and delivering a product or service. A higher gross margin means the company keeps more of each dollar it earns before paying for things like research, marketing, and taxes. When one part of a business has a much higher gross margin than another, the overall margin rises as the higher-margin part grows bigger.

Cash generation has also been consistent. Free cash flow — the cash left over after Apple pays for its operations and capital spending — was $93.0 billion in 2021 and $98.8 billion in 2025. That cash is being used aggressively. In 2025 alone, Apple returned $89.3 billion to shareholders through share repurchases and paid out $15.4 billion in dividends. Net debt — what Apple owes after subtracting its cash — has fallen from $97.6 billion in 2022 to $67.1 billion in 2025. The balance sheet is getting cleaner even while the company returns enormous sums to shareholders.

Google Antitrust Ruling Threatens a Hidden Revenue Stream
In August 2024, a U.S. court ruled that Google had violated antitrust law. Part of the remedy under consideration is stopping Google from paying Apple to be the default search engine on Apple devices. Apple's 10-K lists this as a high-severity risk. The exact amount Apple earns from this arrangement is not disclosed in the filing, but Apple itself calls it 'substantial.' If that arrangement ends, a meaningful slice of high-margin Services revenue disappears.
Beyond the Google situation, Apple faces four other documented threats that could affect its finances. First, tariffs: starting in early 2025, the U.S. imposed new tariffs on imports from China, India, Japan, South Korea, Taiwan, Vietnam, and the EU. Apple manufactures most of its products in those countries. Tariff costs already showed up in 2025 — they are listed as a reason products gross margin percentage fell slightly, from 37.2% in 2024 to 36.8% in 2025, even as total gross margin improved. Second, single-source components: Apple relies on one or very few suppliers for many critical parts. If one supplier fails or stops making a custom part, there is no quick backup. Third, App Store regulation: the EU's Digital Markets Act is forcing changes to how the App Store operates, and Apple faces active lawsuits worldwide challenging its commission structure. The App Store is one of the fastest-growing pieces of the Services segment. Fourth, AI product safety: Apple is rolling out new artificial intelligence features across its devices. If those features produce harmful or false information, or contain hidden defects, Apple faces potential lawsuits and reputational damage.
What is the App Store commission, and why is it under attack?
When someone downloads a paid app or makes a purchase inside an app on an iPhone, Apple typically takes a cut — historically 30% for many transactions. Regulators and courts in the US, EU, and elsewhere argue this is anti-competitive because Apple controls the only way to install apps on iPhones. If Apple is forced to lower its commission or allow competing app stores, its App Store revenue could fall significantly.
Greater China is another pressure point worth watching. Sales in that region fell from $72.6 billion in 2023 to $66.9 billion in 2024 and fell again to $64.4 billion in 2025. That is a $8.2 billion decline over two years, driven mainly by lower iPhone sales. China is both a major manufacturing base and a major sales market, making it doubly exposed to the current trade tensions.

What does 'net debt' mean?
Net debt is what a company owes in loans and bonds, minus the cash it holds. If a company has $100 billion in debt but also $50 billion in cash, its net debt is $50 billion. Falling net debt generally means the company is in a stronger financial position over time.
Apple has $132.4 billion in cash and marketable securities sitting on its balance sheet as of September 2025. That is a large cushion. But the company also has $91.3 billion in outstanding bond debt, $56.2 billion in manufacturing purchase obligations due mostly within 12 months, and $8.8 billion in a one-time tax payment due within 12 months under a 2017 U.S. tax law. The cash pile looks comfortable, but the near-term obligations are substantial.

Apple spent $34.6 billion on research and development in 2025 — 10% more than the year before. That is 8% of total revenue, a ratio that has held steady for three straight years. The consistency suggests a deliberate choice to keep R&D spending growing in line with the business rather than pulling back.
The Bet
Apple's Services business keeps growing fast enough to offset the natural ceiling on device sales. The iPhone is sold to one person at a time in a market where most potential customers in wealthy countries already own a smartphone. Device revenue is $209.6 billion but grew only 4% in 2025. Services revenue is $109.2 billion and growing at 14% per year. The whole financial improvement story — rising margins, growing profits — depends on Services continuing to scale. If App Store regulation cuts commissions, if the Google search payment disappears, or if Services growth simply slows, the margin expansion story stops, and the business looks much more like a slow-growing hardware company.
Open question
Apple's margin expansion over five years is real and documented. Services growing from $85.2 billion to $109.2 billion in two years is not a small move. But Services faces simultaneous pressure from antitrust regulators in the US and EU, a potential end to the Google default search deal, and a tariff environment that raises the cost of every physical product it sells. Can the Services business grow fast enough to absorb these regulatory and legal headwinds — or are the rules of the App Store and the Google deal the hidden foundations that the entire margin story is built on?

Trade Tariffs and Supply Chain Disruption
Starting in early 2025, the U.S. imposed new tariffs on imports from China, India, Japan, South Korea, Taiwan, Vietnam and the EU. Since Apple manufactures most of its products in these countries, tariffs could increase costs, force the company to find new suppliers, or require price increases that reduce customer demand.
Single-Source Component Dependencies
Apple relies on only one or a few suppliers for many critical parts. If a supplier fails, faces a shortage, or stops making custom parts Apple needs, the company cannot quickly get those components elsewhere, which could halt production of popular products.
App Store Antitrust and Regulation
Apple faces lawsuits and investigations worldwide challenging how it controls app sales and takes commissions. The EU's Digital Markets Act requires major changes to how Apple's App Store works. If Apple loses these cases or must comply with stricter rules, it could lose significant revenue and harm its business model.
Google Search Licensing Revenue Risk
Apple earns substantial revenue from allowing Google to be the default search engine on Apple devices. A U.S. court found Google violated antitrust law in August 2024, and ordered remedies that could prevent Google from paying Apple for this arrangement, potentially eliminating a major income source.
Product Defects and Artificial Intelligence Safety
Apple's new AI features and complex products can have hidden defects that harm users or expose them to false or harmful information. If serious defects occur, Apple could face lawsuits, recalls, damage to its reputation, and reduced customer trust.
