FAQ

How we calculate

Rarity odds are the ones Valve published: Mil-Spec 79.92%, Restricted 15.98%, Classified 3.2%, Covert 0.64%, knife or gloves 0.26%. Skins of the same rarity drop with equal chance. StatTrak™ is every tenth item; gloves never have it.
Wear uses the share of drops across the full Float scale (Factory New 3%, Minimal Wear 24%, Field-Tested 33%, Well-Worn 24%, Battle-Scarred 16%), mapped into the skin’s Float range: a Doppler with a 0–0.08 range almost always drops Factory New.
Steam prices: the case is the weekly sales median, the drop is a cautious price — for rare items no higher than the monthly median and no more than $2000, since Steam does not sell higher. Marketplace prices: the case is the second-lowest price among trusted marketplaces, the drop is the lowest. The $2.49 key is sold only by Valve and cannot be resold.
ROI is the average drop value relative to the opening cost (case and key). When you sell, you get less because of the fee — 13% on Steam, about 5% on marketplaces; the amount after the fee is shown as “when sold”.
Break-even chance is the probability that the drop is worth at least the opening cost. The median drop is the price below which half of the openings land: the average rests on rare knives and gloves, and usually you get far less.
Recalculated every hour on fresh prices. A calculation on average prices does not guarantee a result: in the long run opening cases loses money.
