1.74 Million: The FSD Number That Fuels Musk’s Pay Check

1.74 million. That is the number Tesla is highlighting in its latest shareholder letter as the count of active Full Self-Driving subscriptions. The figure represents a 67% jump from the same period last year, a growth rate that looks impressive on the surface. However, a closer look at the footnotes reveals that this total is not just a count of monthly payers. It is a specific metric designed to align with the operational milestones required for Elon Musk’s 2025 CEO Performance Award.

To understand how we arrived at this figure, it helps to look back at when Tesla changed its sales strategy. Until February 14, 2026, customers could purchase Full Self-Driving as a one-time add-on, with prices reaching as high as $15,000. Anyone who made that upfront payment, even years ago, is still included in the 1.74 million total as long as their vehicle remains active. Since that February deadline, new buyers have only been offered the software as a subscription, costing $99 per month in the United States. The only people excluded from the count are those on free trials.

This accounting method has significant implications for the company’s leadership. One of the key hurdles in Musk’s compensation package is reaching 10 million active FSD subscriptions. By including the hundreds of thousands of owners who paid upfront, Tesla accelerates its progress toward that target. It is a strategic move that blurs the line between a one-time software license and a recurring revenue stream, a distinction that matters to investors trying to gauge the true momentum of the software business.

Tesla’s latest report also highlights a 75% attach rate for new deliveries in North America during the third quarter. The company states this is a nearly twenty-point increase from the previous quarter and suggests that the availability of FSD is driving demand in markets where it is offered. While this is a strong indicator of consumer interest, the letter does not define exactly how this rate is calculated. It is unclear whether this figure includes buyers who started with introductory offers or how many of those users are still paying after the initial months.

The path to the 10 million milestone is long. In the third quarter, Tesla added 260,000 net FSD subscriptions, marking its best quarter to date. If the company maintains this pace, it would take approximately eight years to reach the 10 million mark. However, if it sticks to the average growth rate of the past 12 months, which is roughly 700,000 per year, the timeline stretches out to about 12 years. The compensation package remains active until 2035, giving the company time, but the gap between the current number and the target is still substantial.

Similar accounting adjustments appear elsewhere in the shareholder letter. Tesla’s cumulative delivery count now stands at 10.2 million, a figure that includes any unsupervised Robotaxis placed into commercial operation. This inclusion is designed to match another milestone in the pay package, which targets 20 million total vehicles delivered. As of June 30, the company considered only this delivery milestone to be probable, highlighting the distance to the other operational goals.

The 2025 award structure consists of 12 tranches, each requiring both a market cap milestone and an operational achievement. The operational list includes the 10 million FSD subscriptions, 1 million Optimus robots, 1 million robotaxis in commercial operation, and specific adjusted EBITDA targets. With the FSD number now sitting at 1.74 million, the company has made headway, but the definition of what constitutes a 'subscription' remains the central point of discussion.

For now, Tesla has not disclosed how many of the 1.74 million active users are actually paying the $99 monthly fee versus those who bought the software outright. This lack of transparency leaves investors to interpret the 67% growth in the context of a metric that serves a dual purpose: tracking software adoption and validating executive compensation. The next few quarters will be critical in seeing if the monthly subscription base grows independently of the legacy upfront buyers.
