Tesla’s cost structure is dominated by the cost of building cars: in fiscal 2025 (year to 31 December 2025) its total cost of revenues was $77.7 billion, about 82% of its $94.8 billion revenue, of which automotive costs were $57.2 billion. Operating expenses added $12.7 billion, led by research and development of $6.41 billion, up 41% on costs related to AI. What was left was $4.36 billion of income from operations, a 4.6% margin, according to Tesla’s Form 10-K.
The biggest line. The 10-K says it covers materials, labour, factory overhead and tooling depreciation, shipping, tariffs, warranty reserves, FSD (Supervised) upkeep, connectivity and free Supercharging. It fell 9% in fiscal 2025 as deliveries fell and material costs eased.
02
Services and energy: $20.6 billion
Services and other cost $11.6 billion (used cars, repairs, paid Supercharging, insurance claims), up 17%. Energy generation and storage cost $9.0 billion, up 20% as Megapack and Powerwall deployments grew.
03
Operating expenses: $12.7 billion
R&D was $6.41 billion (7% of revenue), selling, general and administrative $5.83 billion (6%), and restructuring and other $494 million in fiscal 2025.
04
What is left: a thin margin
Total gross margin was 18.0% in fiscal 2025 and income from operations $4.36 billion. Small shifts in price or cost per car move profit a lot at this margin.
What changed in 2025-26
AI moves into the R&D line
Tesla says fiscal 2025 R&D rose $1.87 billion, or 41%, mainly on costs related to AI and other programmes, plus $500 million more stock-based compensation. In the nine months to 30 September 2026 R&D reached $7.08 billion, against $4.63 billion a year earlier, already above the full-year 2025 total.
Capital spending more than doubles
Capital expenditures were $8.53 billion in fiscal 2025. Tesla now expects more than $20 billion in 2026, driven by compute infrastructure and data centres, new production lines and a company-operated fleet; it spent $13.01 billion in the first nine months and signed $30 billion of credit agreements in September 2026.
Tariffs push the other way
The 10-K says lower material costs helped cut automotive cost, partly offset by lower fixed cost absorption and higher tariffs. The Q3 2026 10-Q warns that the current tariff regime weighs more on the energy business than on cars.
Energy gets cheaper to build
Energy gross margin rose to 29.8% in fiscal 2025 from 26.2%, which Tesla links to lower raw material costs and the ramp of the Shanghai Megafactory. In Q3 2026 it shipped the first Megapack with LFP cells made at Gigafactory Nevada.

What it means for you
Read Tesla's margin from the cost side: with costs at about 82% of revenue, the cost per car matters as much as the price.
Track R&D and capital expenditures together each quarter; the AI build-out shows up in both before it shows up in revenue.
Watch energy separately: its 29.8% gross margin in 2025 was far above the 17.8% on cars.
Check the tariff discussion in each 10-Q; Tesla says tariffs affect its energy costs more than its car costs.
Treat any cost per car as an estimate: dividing automotive cost by deliveries gives an average, not the cost of a given model.
The Business Engineer lens
Tesla is running two cost structures at once: a carmaker’s, where cost per vehicle decides the margin, and an AI developer’s, where compute and R&D are paid upfront. The Business Engineer reads the gap between the two as the bet: today’s car margin funds tomorrow’s autonomy and robotics.
Automotive cost of revenues: $57.2 billion in fiscal 2025, covering materials, labour, factory overhead, logistics, tariffs and warranty, out of $77.7 billion total cost of revenues.
In fiscal 2025 cost of revenues was $77.7 billion on $94.8 billion revenue, about 82%, and operating expenses took another $12.7 billion, leaving $4.36 billion of income from operations.
Tesla reports automotive cost of revenues as one total. Dividing the 2025 figure of $57.2 billion by 1,636,129 deliveries gives roughly $34,900 per vehicle, an average across models (our arithmetic).

In short
Tesla’s total cost of revenues was $77.7B in 2025, 82% of revenue: automotive $57.2B, energy $9.0B and services and other $11.6B. Operating expenses added $12.7B (R&D $6.41B, SG&A $5.83B).
Correction (11 Oct 2026): this page’s headline promised a “$50K+ car” cost breakdown and its summary box showed cost percentages that are not in Tesla’s filings. Tesla does not disclose cost per car. From its 2025 10-K, automotive cost of revenues was $57.2B, about $34.9K per vehicle delivered (calculated). The headline now reflects the filing.

Automotive sales are the most critical segment for Tesla, with over $82.4 billion in revenue from automotive parts; most of the gross profits come from automotive sales, with over $16 billion in gross profits, or a 19.4 % gross margin. However, the “energy platform” (generation & storage) is contributing more and more to it. With revenue of $6 billion, a gross profit of over a billion dollars, and gross margins of 18.9%, this might become a critical component of the business model, thus changing its whole strategy.
Making the automotive segment critical, followed by other segments like energy storage and generation.
By 2020, as Tesla started to reach mass manufacturing, its profitability also widely improved, going from less than a billion in 2020 to over $12.5 billion in 2022.
Tesla is vertically integrated. Therefore, the company runs and operates the Tesla’s plants where cars are manufactured and the Gigafactory which produces the battery packs and stationary storage systems for its electric vehicles, which are sold via direct channels like the Tesla online store and the Tesla physical stores.
In 2023, Tesla generated $96.77 Billion in revenues. Tesla’s business model primarily relies on automotive sales, $78.5 billion (over 81% of the total revenues); services/others followed with over $8 billion; energy generation and storage generated over $6 billion in revenues.

Tesla didn’t have an official advertising budget until 2023, to spend on advertising, as it has almost been null over the years. Indeed, Tesla leveraged a combination of Elon Musk’s ability to generate significant media coverage and build a product that sold via word of mouth and directly to consumers.
Tesla was profitable in 2023, with a net profit of $14.99B, compared to $12.55 billion in 2022. Tesla has been profitable since 2020. Indeed, Tesla generated $721 million in net profits in 2020 and $5.5 billion in 2021.
Tesla R&D’s costs have doubled in absolute number, from almost $1.5 billion in 2020 to nearly $4 billion in 2023. Yet they have decreased as a percentage of revenue, from 5% in 2020 to 4% in 2022 and 2023. These R&D expenses primarily comprise costs associated with personnel for teams in engineering and research, manufacturing engineering and manufacturing test organizations, prototyping expenses, contracts, and professional services.
Elon Musk, seen as one of the most visionary tech entrepreneurs from the Silicon Valley scene, started his “career” as an entrepreneur at an early age. After selling his first startup, Zip2, in 1999, he made $22 million, which he used to found X.com, which would later become PayPal, and sell for over a billion to eBay (Musk made $180 million from the deal). He founded other companies like Tesla (he didn’t start it but became a major investor in the early years) and SpaceX. Tesla started as an electric sports car niche player, eventually turned into a mass manufacturing electric car maker.
Founded in 2003 by Eberhard and Tarpenning, eventually, the initial co-founders left the company, and by 2004, Musk first became the main investor. After that, by 2008, he took over as CEO of the company. Tesla would go through many near-death experiences until 2018. And yet, by 2021, Tesla will become a trillion-dollar company.
Tesla is vertically integrated. Therefore, the company runs and operates the Tesla’s plants where cars are manufactured and the Gigafactory, which produces the battery packs and stationary storage systems for its electric vehicles, which are sold via direct channels like the Tesla online store and the Tesla physical stores.
As an electric automaker and builder of sports cars and now trucks, Tesla’s competitors comprise companies like Ford, Mercedes-Benz, Porsche, Lamborghini, Audi, Rivian Lucid Motors, Toyota, and more. At the same time, Tesla is an electric energy production and storage company (SolarCity); it competes with Sunrun, SunPower, and Vivint Solar. And as an autonomous driving company, it competes with companies like Zoox, Waymo, and Baidu with self-driving software.
A real-time insurance business model enables Tesla to build its insurance arm by dynamically adjusting the premiums based on real-time driving behavior. Reduced insurance premiums hooked with the leasing arm enable Tesla to scale its demand side of the business.

The Business Engineer view: cost per car is the lever
Automotive cost of revenues fell from $66.4B in 2023 to $57.2B in 2025 as volumes dropped, but revenue fell faster, so gross margin stayed near 18% (Tesla 2025 10-K).
