Tesla's FSD Numbers: A Paycheck Puzzle

Tesla is reporting a massive surge in its Full Self-Driving software. The company claims it now has 1.74 million active subscriptions. That is a 67% jump from the same time last year. However, the number relies on a specific counting method. This method favors the CEO's pay package. It counts owners who bought the software outright as if they are monthly subscribers. This creates a tension between reported growth and actual monthly revenue.

The timeline for this metric is tied to Tesla's leadership compensation. In 2025, the board approved a performance award for Elon Musk. This award has twelve parts. Each part requires a specific operational milestone. One of these milestones is reaching 10 million active FSD subscriptions. To hit that target, the company adopted a definition that includes upfront purchases. This definition was chosen to match the requirements of the pay package. It was not a new business metric for investors.

Tesla changed how it sells the software earlier this year. On February 14, 2026, it stopped selling FSD as a one-time purchase. New customers in the US must now pay $99 per month. However, everyone who paid before that date remains in the count. Some of these owners paid up to $15,000 years ago. As long as their car is active, they count toward the 1.74 million total. The only exclusion is free trials. Tesla has not disclosed how many of the 1.74 million are actually paying the monthly fee.

The company uses a similar approach for its delivery numbers. The letter states that cumulative deliveries now stand at 10.2 million. This figure also counts unsupervised Robotaxis placed in commercial operation. This matches another milestone in Musk's pay package, which targets 20 million vehicles. Tesla also reported a 75% attach rate for new deliveries in North America. This means 75% of new cars sold in Q3 included an FSD subscription. That is a nearly twenty percentage point increase from the previous quarter. Tesla believes this software is driving demand in available markets.

The road to the 10 million milestone is long. Tesla added 260,000 net FSD subscriptions in Q3. That is its best quarter yet. At this pace, it would take about eight years to reach the goal. If it maintains its average of roughly 700,000 new subscriptions per year, the timeline stretches to about 12 years. The award runs until 2035. As of June 30, Tesla considered only the 20 million delivery milestone probable. The others, including the 10 million FSD target, remain uncertain.

What happens next is clear. Tesla will continue to report these numbers. The board will track progress against the 2035 deadline. Investors will watch to see if the 75% attach rate holds up. The company has not said if this rate includes introductory offers or if those buyers stay after a few months. The definition of a subscriber is now central to the company's narrative. It is also central to the CEO's potential payout.

Tesla has not released a breakdown of monthly versus upfront users. The company knows the number. It has chosen not to share it. The focus remains on the total count. This count includes hundreds of thousands of owners who were sold the promise of unsupervised driving. Tesla has not yet delivered that fully autonomous capability. For now, the software is supervised. The metric, however, is already in play.
