indielist estimates lifetime unit sales for Oxygen Not Included at roughly 6.3 million to 14.8 million copies, with a median around 10.6 million, derived from its 132,250 Steam reviews using a multi-factor Boxleiter model (version v1.0). That median maps to approximately $151.0M in net revenue after Steam's 30% cut, regional pricing, and refunds. Unlike black-box trackers, the full calculation is shown on this page: a base review-to-sales multiplier is adjusted for release year, launch price, review sentiment, studio size, and genre, and every adjustment is listed so developers, publishers, and investors can audit exactly how the figure was reached. The range itself reflects genuine uncertainty — review-to-sales ratios vary widely between games — so indielist publishes a low, median, and high band rather than a false-precision single number, and treats free-to-play, heavily discounted, and bundle-distributed titles as having wider error margins still.
