Netflix charges people a monthly fee to watch TV shows, movies, and live programming through the internet. Members pay anywhere from the equivalent of $1 to $37 per month depending on their country and their plan. The company also earns some money from advertising shown on a cheaper ad-supported plan, but monthly membership fees are the main engine. The more members pay, and the more members there are, the more Netflix can spend on content to attract even more members. The diagram below traces where the money goes.
Five years of numbers tell a clear story. Revenue has grown every single year, from $29.7 billion in 2021 to $45.2 billion in 2025. That is not the most striking part. The more important shift is what happened to the money Netflix kept after paying its costs.
In 2021, Netflix generated just $0.4 billion in cash from its operations, and free cash flow was actually negative at minus $0.1 billion. That meant the business was spending more cash than it was bringing in. By 2023, that had completely reversed. Operating cash flow jumped to $7.3 billion and free cash flow reached $6.9 billion. In 2025, operating cash flow hit $10.1 billion and free cash flow reached $9.5 billion. The turnaround came from revenue growing faster than costs. Gross margin climbed from roughly 42% in 2021 to roughly 48% in 2025, meaning Netflix kept a larger slice of every dollar it earned.
Operating margin also improved sharply. It stood at 20.6% in 2023, rose to 26.7% in 2024, and reached 29.5% in 2025. Netflix has been converting a growing share of its revenue into actual profit. Net income grew from $5.4 billion in 2023 to $10.98 billion in 2025. Net debt, which is what the company owes minus the cash it holds, fell from $9.4 billion in 2021 to $5.4 billion in 2025, showing the balance sheet getting healthier as cash generation improved.
That financial progress is real. But several documented risks could disrupt it. The first is content. Netflix depends on studios and other rights holders to license shows and movies. If those companies refuse to license content on acceptable terms, or pull content away quickly, Netflix may not have enough programming to keep members subscribing. The second is infrastructure. Netflix runs most of its computing on Amazon Web Services. If Amazon were to disrupt or cut off that service, Netflix's streaming operations would be severely affected. The third is cost structure. Netflix signs multi-year content deals with fixed prices that do not shrink if membership growth slows. If members stop growing but content bills keep coming, margins could fall fast.
The biggest new risk sits just ahead. Netflix has signed a definitive agreement to acquire Warner Bros. Discovery's streaming and studios businesses, including HBO Max, HBO, and film and television studios, at an enterprise value of approximately $82.7 billion. To fund this, Netflix has arranged up to $42.2 billion in new borrowing through a senior unsecured bridge loan facility. That would dramatically increase the company's debt load after years of paying it down. Netflix currently carries $14.5 billion in debt. Adding $42.2 billion in potential new borrowing would be a major change. Higher debt means higher interest payments and less financial flexibility.
Netflix stopped reporting subscriber numbers in 2025, shifting to revenue and operating margin as its primary measures of success. That change makes it harder for outside observers to track how many people are actually joining or leaving the service. The company says revenue and margin best represent business performance, but it also means one of the most watched signals in streaming is no longer publicly available.
The advertising plan and the Warner Bros. Discovery deal both point in the same direction. Netflix is trying to grow revenue in a market where membership in many developed countries is already widespread. More members from new price points, more content from a major studio acquisition, and more advertising dollars are the three levers. Each comes with its own cost and risk.
