How We Estimate Steam Revenue

Copies sold are estimated with the Boxleiter method: the number of Steam user reviews a game has received is multiplied by a review-to-sales ratio. The ratio is not a single constant. It varies with release year, price band, genre, and how long the game has been on sale, because players review cheap and recent games at different rates than expensive or older ones.

Because the ratio is uncertain, we show copies sold as a range (a low and a high estimate) rather than a single figure. When one number is needed, such as in a ranking table, we label the upper bound. For free games, ownership is not a purchase; owner estimates should not be interpreted as copies sold.

Gross revenue is estimated copies sold multiplied by the game’s price, adjusted for its pricing history and discounts. It approximates what players paid at the Steam checkout.

Net revenue is gross revenue after Steam’s platform share and typical deductions such as regional pricing differences, refunds, and taxes. This is modeled net receipts, not profit, verified payouts, or the developer’s contractual share. Net revenue is the headline figure on game pages and the basis of the Top Revenue ranking.

All monetary figures use USD. Revenue and ownership estimates are cumulative through the available observation, not earnings during the selected release year. Neither figure includes DLC, in-game purchases, or sales on other storefronts.

Each revenue estimate carries a confidence score from 0% to 100%. It is a relative indicator of how well-supported the estimate is, not a probability that the number is exactly right. Games with many reviews, a stable price, and a long sales history score higher. New releases, free-to-play titles, and games that changed price often score lower.

Treat a low-confidence estimate as an order-of-magnitude figure rather than a precise one.

Player counts are concurrent players in the available observations, not live counts or daily peaks. A matching historical observation date is shown on the game page when available; otherwise its collection date is unknown.

• Top Revenue sorts by estimated net revenue.
• Most Owned sorts by the upper bound of estimated lifetime owners, including free-game ownership.
• Most Played sorts by concurrent players in the available observations.
• Top Reviewed sorts by a volume-weighted review score. Each game’s positive-review share is shrunk toward 80% by 500 pseudo-reviews, so a game with 100 perfect reviews does not outrank one with 100,000 reviews at 97%. Only games with at least 100 reviews qualify. The adjusted ranking score is displayed separately from the raw positive-review percentage. Revenue availability is not required.
• New Releases sorts tracked released games by date, newest first, regardless of review count or revenue availability. Future release dates are excluded using the export date.

Every ranking lists up to 1,000 games and is rebuilt with each data export.

• Bundles, key giveaways, and heavy regional discounting can inflate review counts relative to revenue.
• Free-to-play games earn through in-game purchases that this model does not see.
• Games that were free for a period, or that shipped on a subscription service, will be overestimated.
• Review bombing or review incentives distort the review-to-sales ratio for the affected period.
• Estimates are for Steam only. Console, mobile, and other PC storefronts are not included.
