Estimated lifetime sales and revenue

	Low	Medium	High
Copies sold	30,120	57,228	82,830
Net revenue (USD)	$209,386	$397,833	$575,811

Steam doesn't publish sales. These estimates multiply the number of reviews by a factor that depends on the release year (the Boxleiter method). Net revenue is what's left of list price × sales after refunds, regional pricing, discounts, sales tax and Steam's 30% cut, before any publisher's share. Treat them as a ballpark for comparing games, not as reported figures.
