Market Size for Chrome extension in 2026 [Example]

The total addressable market (TAM) for a Chrome extension is vast globally, considering the number of internet users.

As of 2023, there are approximately 5 billion internet users worldwide. Assuming that 10% are actively using Chrome and might consider extensions, that gives us roughly 500 million potential users.

If we estimate an average annual spend of $3 per user on various types of Chrome extensions (given many are low-cost or free), this results in a TAM of $1.5 billion annually.

The serviceable available market (SAM) assumes we focus on users needing extensions related to specific niches, such as productivity, privacy, or ad-blocking.

If we narrow down to just 20% of the TAM, we reach around 100 million potential customers looking specifically for these types of extensions.

At an estimated average annual spend of $3 per user for niche Chrome extensions, this gives a serviceable market of about $300 million.

The serviceable obtainable market (SOM) reflects a more conservative estimate of what a new Chrome extension can realistically capture in the first year.

Taking 1% of the SAM, we predict capturing around 1 million users in the first year. However, focusing on a specific audience and marketing effectively, we will primarily aim for approximately 1,000 paying customers.

If we assume an average annual spending of $3 (same as in previous calculations), this results in projected revenue of about $3 million for the first year.
