How CS2 trade-up contracts work
Inputs & odds
10 skins of one rarity become 1 skin of the next rarity (Mil-Spec → Restricted → Classified → Covert). Since the October 2025 update, 5 Covert skins can become a knife or gloves from those skins' case. Each input collection gets its share of the odds (inputs from it ÷ total), split evenly across that collection's next-tier skins.
Float math
Every input float is normalized to its own skin's range — (float − min) ÷ (max − min) — and averaged. Each output's float is its min + average × (max − min), so a restricted-range skin like 0.10–0.20 can only land in the wears its range allows.
Prices, fees & freshness
Values are Steam Community Market averages from the snapshot dated on each page. Profit subtracts the ~13% Steam seller fee. StatTrak™ inputs give StatTrak™ outputs (knives only — gloves have no StatTrak™). Map collections outside weapon cases aren't in DropLabz's dataset yet.
Pick the skin you want in the reverse trade-up finder, check any contract in the trade-up calculator, or compare with opening cases on case ROI and knife odds.
