Steam Revenue Estimator

A game with 1,000 reviews at 20.00 a copy leaves its developer roughly 420,000: about 30,000 copies, 600,000 gross, minus Steam's 30 %. The copy count comes from a rule of thumb — thirty sales per review — so the spread around this figure is wide. Nobody outside Valve sees the real numbers.

The interesting number about a game on Steam is not what it grossed but what reaches the studio, and this estimator works its way there from the only two figures anyone outside Valve can see: the public review count and a typical selling price. The chain has three links — reviews to copies, copies to gross, gross to the developer's share. At the preset values, 500 reviews multiplied by thirty give an estimated 15000 copies; at 19.99 each that is 299850 in gross sales; the first-tier cut of 30 % takes 89955 and leaves 209895. Only the last link rests on published terms. The tier boundaries at ten and fifty million dollars are Valve's own, and they never come into play at this scale: the default game would need more than thirty times its gross to reach the first one. What the answer is not is money in hand. It is a share of sales, standing before the cost of making the game, before anything owed out of that share to others, and before income tax. And the whole result inherits the uncertainty of its first link. Exact fee arithmetic on top of an estimated copy count does not make the estimate precise — it makes it precisely as uncertain as the multiplier is. Read it as an order of magnitude and replace it with real reporting as soon as you have any.
