How many employees does Tesla have? Headcount by year from its 10-K

This page is for sellers, analysts and anyone who needs a Tesla headcount they can cite: the latest number, what it counts and how it has moved. Data sites estimate Tesla's size from online profiles, and their figures don't match the company's. Every number here comes from Tesla's annual report on Form 10-K or other documents it filed with the SEC.

Tesla employees by year

Tesla reports its headcount once a year, as of December 31, in the Human Capital section of its 10-K.

Tesla gives exact counts, not rounded ones. The changes are our arithmetic. Tesla's 10-Qs and quarterly update letters don't report headcount, so the 2025 10-K holds the latest company figure until the 2026 10-K arrives, usually in late January.

What the number includes

The wording has changed twice, which matters when you compare years.

• Worldwide, including subsidiaries. The 2020 to 2022 filings say so outright, and the later ones say "worldwide". Tesla runs factories in the US, China and Germany, but the 10-K gives no split by country or segment.
• Full-time is no longer stated. Up to 2022 the count was described as full-time. From 2023 the filing says "employee headcount" with no full-time qualifier and no separate part-time figure.
• Contractors aren't mentioned. The Human Capital section doesn't say whether contractors or temporary workers are counted or how many there are. Read the figure as Tesla's own employees.
• Unions. The risk factors say that "labor unions have engaged in campaigns to organize certain parts of our operations." The 10-K doesn't give a count of represented employees.
• A point-in-time count on December 31, not an average for the year.

What changed and why

2018 and 2019: a cut after fast growth

On January 18, 2019 Tesla filed Elon Musk's email to employees, which said Tesla had "no choice but to reduce full-time employee headcount by approximately 7%" and that "we grew by 30% last year, which is more than we can support." The 10-Ks match the 30%: 37,543 at the end of 2017, 48,817 at the end of 2018. By the end of 2019 headcount was 48,016.

2020 to 2023: the factory build-out

Headcount nearly tripled in four years, to 140,473. The 2022 10-K describes that year's count as "a 29,000 year over year increase" (our arithmetic from the two filings gives 28,565).

2024: more than 10% cut

On April 15, 2024 Tesla "announced a company-wide restructuring that reduces our headcount by more than 10% globally," according to an 8-K filed the next day, which adds that "there has been a duplication of roles and job functions in certain areas." The 2024 10-K says Tesla recognized "$583 million of employee termination expenses" in the second quarter, within $684 million of restructuring and other expense for the year. Year-end headcount fell 14,808, or 10.5%.

2025: growth despite new cost actions

In the third quarter of 2025 Tesla "initiated certain actions in order to reduce costs and improve efficiency," and the 2025 10-K records $390 million of expenses in the automotive segment in the second half for "supercomputer assets, contract terminations and employee terminations." It doesn't say how many roles were affected. Total headcount still rose by 9,120.

Revenue per employee

Tesla's 2025 total revenues were $94,827 million. Divided by the year-end headcount, that's $94,827 million ÷ 134,785 = about $703,500 per employee (our calculation).

The ratio fell in 2025 because revenue dropped 2.9% while headcount grew 7.3%. By segment, automotive and services and other brought in $82,056 million in 2025 (87% of revenues) and energy generation and storage $12,771 million (13%). Tesla doesn't report headcount by segment, so there's no per-segment ratio. Compare the ratio only with figures built the same way, such as those on our list of the largest auto companies.

Selling to a company this size

General guidance on how manufacturers of 135,000 people buy, not a description of Tesla's internal processes.

• Know which side you sell to. Factory, supply chain and energy-storage teams buy very differently from engineering and software teams. Find the plant or program that has the problem.
• Read the cost language. A company that cut over 10% for duplicated roles and keeps announcing cost actions judges vendors on cost per unit and output per person. Lead with the saving, in their numbers.
• Expect supplier qualification. Manufacturers vet suppliers on quality, capacity and security before a first order. Build that time into your plan.
• Land with one site or team. Win at one plant or function and use the result to reach the next: the land and expand motion.
• Name the people. Work out who signs, who uses and who can block. Our guide to finding decision makers shows how.

In an account this large, working out which team owns your problem is most of the job. Bebop researches each account and suggests who to talk to and the angle to open with; check what it finds against the company's filings.

How to check Tesla's headcount yourself

1. Search SEC EDGAR for Tesla, Inc. (CIK 1318605) and open the latest 10-K, filed each year in late January or early February.
2. In Item 1, Business, find Human Capital Resources. The headcount and its date are in the first paragraph.
3. Check the 8-Ks filed since then for announced workforce changes, and the restructuring note in the latest 10-Q for charges.
4. Before comparing with another company, check the basis: Tesla's recent filings give one worldwide headcount with no full-time or part-time split.
