How does Tesla make money?
Tesla designs, builds and sells its own cars and sells them directly, without independent dealers. Its 10-K lists five consumer models: Model 3, Model Y, Model S, Model X and Cybertruck. In 2025 it produced about 1.66 million and delivered about 1.64 million vehicles.
Revenue in 2025 by line: automotive sales $65.8 billion, about 69.4%, down 9% because cash deliveries fell about 8% and average prices were lower. Energy generation and storage $12.8 billion, about 13.5%, up 27%. Services and other $12.5 billion, about 13.2%, up 19%. Regulatory credits $2.0 billion, about 2.1%, down 28%. Automotive leasing $1.7 billion, about 1.8%. Tesla reports two segments: automotive, which includes credits, leasing and services, and energy generation and storage.
- Deliveries
- Vehicles handed over to customers in a period. Carmakers count them separately from production, and Tesla’s deliveries drive most of its automotive revenue.
What are Tesla’s regulatory credits?
Governments set emission and other standards for carmakers. Because Tesla builds only electric vehicles, it earns tradable credits under those rules and sells them to other carmakers that need them to comply. Tesla’s 10-K says these sales have negligible incremental costs, so almost all of the revenue is profit.
That is why a small revenue line matters. In 2025 regulatory credits brought in $2.0 billion, about 2% of revenue but equal to about 46% of operating income. Without them, the automotive gross margin of 17.8% would have been about 15.4% by our calculation. The 10-K says credit revenue fell 28% in 2025 and that government actions, including the One Big Beautiful Bill Act enacted in July 2025, restricted certain credit programs tied to its products.
- Regulatory credits
- Tradable credits that a carmaker earns by beating emission or similar standards and can sell to carmakers that fall short. For Tesla they carry negligible cost, so the revenue is almost all profit.
How profitable is Tesla’s car business?
Gross margin is the share of revenue left after the direct cost of making what was sold. Tesla’s total automotive gross margin fell from 19.4% in 2023 to 18.4% in 2024 and 17.8% in 2025, as average selling prices fell, incentives rose and credit revenue shrank. Its company-wide gross margin was 18.0% in 2025.
Below gross profit, operating expenses rose to $12.7 billion from $10.4 billion, led by research and development, up about 41% to $6.4 billion. Operating income was $4.4 billion, an operating margin of about 4.6%, and net income attributable to shareholders was $3.8 billion against $7.1 billion in 2024. The income statement lesson walks through each of these lines.
- Gross margin
- Gross profit divided by revenue: the share of each sales dollar left after the direct cost of the products or services sold, before research, selling and administrative costs.
How big is Tesla’s energy business?
Tesla deployed 46.7 GWh of energy storage in 2025: Megapack, for utilities and commercial and industrial customers, and Powerwall, for homes and small businesses. Energy generation and storage revenue rose 27% to $12.8 billion and its gross margin rose to 29.8%, so the segment earned $3.8 billion of gross profit: about 22% of Tesla’s total on about 13.5% of revenue.
Services and other revenue, $12.5 billion, includes used vehicle sales, maintenance and collision repair, paid Supercharging, insurance, and parts. It grew 19% but has a thin margin: its gross profit was about $0.9 billion, about 7%.
- GWh (gigawatt-hour)
- A unit of energy equal to a million kilowatt-hours. Battery makers use it to measure how much storage capacity they delivered or deployed in a period.
Where do FSD, Robotaxi and Optimus fit in?
Tesla’s 10-K describes the company as focused on bringing AI into the real world through Full Self-Driving (Supervised), its Robotaxi service and AI robots such as Optimus. Robotaxi, an autonomous ride-hailing service, launched in June 2025. None of these has its own revenue line: FSD (Supervised) features sold with cars are recorded in automotive sales, and the 10-K does not report separate revenue for Robotaxi or Optimus.
So when you read Tesla’s results, separate what the business earns today, mostly cars and energy storage, from plans that are not yet visible in revenue. Research and development spending, which rose to $6.4 billion in 2025, and capital expenditures of $8.5 billion pay for both.
What should you watch in Tesla’s results?
Tesla publishes vehicle production and delivery numbers, with energy storage deployments, shortly after each quarter ends, and full results a few weeks later after the US market close. Tesla is also one of the Magnificent Seven. Read these each quarter:
- Deliveries and production, and the gap between them, which shows whether inventory is building.
- Automotive gross margin, and how much of it comes from regulatory credits.
- Energy storage deployments and the energy segment’s gross margin.
- Operating expenses, especially research and development, and operating income.
- Capital expenditures and cash; see how to read earnings reports.
