How the simulator works
- Real odds: Mil-Spec 79.92%, Restricted 15.98%, Classified 3.20%, Covert 0.64%, knife or gloves 0.26% (the published CS2 case odds). StatTrak™ 10%.
- Wear: Factory New 3%, Minimal Wear 24%, Field-Tested 33%, Well-Worn 24%, Battle-Scarred 16%, then a random float inside the skin's own range.
- Prices: Steam Community Market, refreshed every hour, before the 13% Steam fee; knives and gloves above Steam's $2,000 listing cap use the lowest marketplace price. Change the case price to match today's market.
- Expected value is the average value of one opening at today's prices. Every case is below the $2.49 key + case cost on average; the simulator shows you how far below.
- Nothing is bought or opened for real. It is a free calculator, not a case site.
