The short answer
Netflix makes money by charging people a monthly fee to watch its library of films, TV shows, documentaries, and live events. That subscription fee is, and has always been, the engine of the business. More recently, the company added a second revenue stream: advertising. Subscribers who choose a lower-priced plan sit through a handful of ads per hour, and Netflix sells that ad inventory to brands.
Those are the two income lines. Everything else — the password-sharing crackdown, the price increases, the billions spent on original programming — is either a way to protect that subscription revenue or a move to grow it.
Subscriptions: the core engine
Netflix offers three plans in most markets: a lower-priced ad-supported tier, a standard ad-free tier, and a premium tier that adds 4K Ultra HD, HDR, better audio, and more simultaneous screens. Exact prices vary by country and change over time, and Netflix has raised them repeatedly over the past decade.
Price increases are a deliberate part of the model. Netflix has gotten away with raising rates because subscriber churn — the rate at which people cancel — remains among the lowest in the industry. When a company can lift prices without losing many customers, that signals genuine pricing power. Beyond the base tiers, Netflix introduced an extra-member add-on that lets account holders pay to add someone outside their household, giving it a way to monetize relationships that previously cost it nothing. With over 300 million paid members globally at the end of 2024, that scale gives Netflix enormous leverage. Curious how this compares with other company business models? Subscription businesses live or die on how much a customer pays over their lifetime versus what it costs to acquire them.
The new advertising tier
Netflix spent most of its history proudly ad-free, positioning itself as a clean alternative to commercial television. That changed in November 2022, when it launched an ad-supported plan in a dozen markets including the US, UK, and Canada. The reasons converged: subscriber growth had slowed after a pandemic-era boom, the company reported its first loss of paid members in a decade in early 2022, and a cheaper ad tier offered a way to attract price-sensitive viewers who wouldn’t pay full price.
The bet has paid off. By early 2025 the ad-supported plan had reached tens of millions of monthly active users, and in markets where it’s available the cheaper tier accounted for a majority of new sign-ups. Netflix roughly doubled its advertising revenue year-over-year in 2024 and built its own first-party ad technology platform. That said, advertising remains a small fraction of overall revenue compared with subscriptions — the subscription base is simply too large for ad income to close the gap quickly. The long game is to build advertiser confidence and grow the ad-tier audience.
How Netflix spends money: content is the big cost
Netflix’s cost structure is not complicated. The dominant expense is content — producing it, licensing it, and marketing it. In 2024 the company spent roughly $17 billion on content on a cash basis, with plans to spend even more in following years as it expands into live events, sports rights, and other formats. Why spend so much? Because content is both the product and the moat. A subscriber halfway through a must-watch series is not going to cancel, and original programming that can’t be found anywhere else gives Netflix a reason to exist that a cheaper or free competitor can’t easily replicate. After content, the next costs — technology, infrastructure, marketing, and operations — are real but modest by comparison.
Crackdown on password sharing
For years, Netflix tolerated subscribers sharing passwords with people outside their household. Estimates suggested over 100 million households were watching through someone else’s account — an enormous pool of potential paying customers. In 2023, Netflix began enforcing its one-household rule in earnest, starting in Latin America before reaching the US in May 2023. The rule is simple: an account is for one household, and access for someone elsewhere requires a paid extra-member slot.
The online reaction was loud, with predictions of mass cancellations. What actually happened was different: Netflix added more than nine million paid subscribers in the first quarter of 2024 alone, beating expectations, and confirmed the paid-sharing initiative was revenue and membership positive across every region. This one policy change is arguably the most consequential business decision Netflix made in the 2020s — it turned a long-tolerated leak into a growth lever, helping push its subscriber count past 300 million. Understanding the money behind it explains a lot about the company’s recent results.
Is Netflix profitable?
Yes, and increasingly so. For the full year 2024, Netflix reported double-digit revenue growth and an operating margin of about 27% — up several points from the prior year — and operating income crossed $10 billion for the first time in its history. The company has also shifted from a growth-at-all-costs posture to generating substantial free cash flow, and has begun returning capital to shareholders through share buybacks. For much of its history Netflix wasn’t strongly profitable on a cash basis because it was spending aggressively to build its library; that era has shifted as the business matures.
The bottom line
Netflix makes money one way above all others: it charges people a monthly fee to watch content they can’t get elsewhere. Everything the company has done in recent years — adding an ad tier, cracking down on password sharing, raising prices, spending billions on programming — connects back to protecting and growing that subscription relationship. The advertising business is real and growing fast, but it’s still a secondary income stream; the content spending is enormous, but it’s also the reason people stay subscribed. If you want to understand almost any decision Netflix makes, start with this: what does it do for subscriber count, and what does it do for how much each subscriber pays? Follow the money, and the logic of the business becomes clear.
