Tesla makes money in two main ways. First, it designs and sells electric vehicles, including the Model 3, Model Y, Model S, Model X, and Cybertruck, directly to customers through its own stores and website. Second, it makes and sells energy products like the Powerwall home battery and the Megapack, a large battery system used by power companies and businesses. On top of those core sales, Tesla earns money from paid Supercharger sessions, used car sales, automotive insurance, FSD (Full Self-Driving) software subscriptions, and the sale of regulatory credits to other car companies who need them to meet emissions rules. In June 2025, Tesla also launched a Robotaxi service, an autonomous ride-hailing platform that uses its own vehicles and AI technology. Together, these streams make Tesla something unusual: part car company, part energy company, part software business. The diagram below traces where the money goes.
Five years of financial data tell a story of rapid growth followed by a plateau, with margins under real pressure. Revenue climbed sharply from 2021 to 2023, then essentially stopped growing. In 2023, total revenue reached $96.8 billion. In 2024, it nudged up to $97.7 billion. In 2025, it fell back to $94.8 billion. That is three years of flat to falling revenue after years of strong gains.
The margin story is harder to ignore. In 2021 and 2022, Tesla's gross margin sat just above 25%. That means for every dollar of revenue, Tesla kept about 25 cents after paying for materials and manufacturing. By 2023, that figure had dropped to around 18%, and it has stayed near that level through 2025. The company cut vehicle prices aggressively to keep demand up, and that decision squeezed profits. Automotive gross margin fell from 19.4% in 2023 to 17.8% in 2025.
One bright spot is the energy business. Energy generation and storage revenue grew from $6.0 billion in 2023 to $12.8 billion in 2025, and its gross margin expanded from 18.9% to 29.8% over the same period. That is the fastest-growing and now most profitable part of the business on a margin basis. Megapack deployments drove most of that growth as electricity grids worldwide scrambled to add storage capacity alongside solar and wind power.
Despite the margin compression, Tesla kept generating cash. Operating cash flow was $14.7 billion in 2025, close to the $14.9 billion it produced in 2024. Free cash flow improved to $6.2 billion in 2025 from $3.6 billion in 2024, partly because Tesla spent less on factories. The company ended 2025 with $44.1 billion in cash and investments, which gives it a large financial cushion. But Tesla has also flagged that it expects capital expenditures to exceed $20 billion in 2026, driven by AI infrastructure, new factories, and robotics. That is a significant step up in spending.
Regulatory credit sales fell from $2.8 billion in 2024 to $2.0 billion in 2025. A new US law called the One Big Beautiful Bill Act, enacted in July 2025, restricted some of these credit programs and also removed the consumer tax credit that helped make electric vehicles more affordable for buyers. Both changes hit Tesla at the same time: less income from credit sales, and potentially less demand from price-sensitive buyers who relied on that tax break.
Beyond policy changes, Tesla faces several documented threats that could affect the business regardless of how well it executes. Tariffs introduced in 2025 have already raised costs on imported components, and the company says further tariff changes could disrupt its global supply chain. Tesla relies on a small number of suppliers for battery cells, including Panasonic and CATL, and has limited ability to switch quickly if those relationships break down. The raw materials inside batteries, particularly lithium and nickel, can swing sharply in price based on global demand, and Tesla cannot always pass those increases on to customers without losing sales.
Tesla's newest products carry the biggest execution risks. The Robotaxi service launched in June 2025 but regulations around fully autonomous vehicles differ in every city and country, and the legal framework is still evolving. Cybercab, a purpose-built autonomous vehicle, has not yet entered full production. Optimus, a humanoid robot Tesla is developing, is still in early stages. The company plans to ramp six new production lines in 2026 across vehicles, robots, energy storage, and battery manufacturing. Past production ramps at Tesla have caused major delays and cost overruns. There is no guarantee the next wave will be different.
Tesla is also competing in a car market that is genuinely getting more crowded. Every major car company now sells electric vehicles in the US, China, and Europe. In China specifically, local manufacturers have launched competitive electric vehicles at aggressive prices, putting pressure on Model 3 and Model Y sales in what has been one of Tesla's most important markets. Services revenue from paid Supercharging, insurance, and maintenance grew 19% to $12.5 billion in 2025, which shows that the installed base of Tesla vehicles creates ongoing income. But that income depends on a fleet that has to keep growing, and vehicle deliveries actually fell in 2025.
