EV ratio is the expected value of the results divided by the input cost, before marketplace fees, with every skin at its lowest listed price (without Tradeit) on 26 October 2026. The inputs are priced at the max input float of their wear: lower floats cost more and can return better wears. Chance of profit is the chance of a result worth more than the inputs.

How to use this page
Search for a case or collection, open it and filter its skins by weapon, rarity, wear or quality. Open a skin to see its price on each marketplace.
The total and average add up the lowest price of each skin that has one. The price gap is the difference between the cheapest and the most expensive version of a skin.
Cases, collections and trade ups
A case drops skins from its own collection. In a trade up, the collection of each input decides which skins the contract can return — see how CS2 trade ups work or build one in the trade up calculator.
