Trade-Up Contract Simulator

A trade-up contract lets you trade 10 skins of the same rarity for 1 skin of the next higher rarity. The outcome is randomly chosen from the next tier of the same collections as your input skins. For example, 10 Mil-Spec Grade skins will produce 1 Restricted skin.

Outcomes are determined by the collections of your input skins. Each input skin adds its collection's next-tier skins to the outcome pool. If you use skins from 3 different collections, outcomes from all 3 collections are possible. The game randomly selects one outcome from this combined pool.

Yes. In-game, the average float of your input skins influences the output float. Lower average input floats generally produce lower output floats. This simulator focuses on collection/rarity mechanics — for float-specific calculations, check dedicated float calculators.

Yes! Since the CS2 Retake Update, you can trade up 5 Covert skins for a chance at Knives or Gloves. This is a special trade-up that only requires 5 inputs instead of the usual 10. Knife and glove trade-ups are high-risk but can yield extremely valuable items.

Yes, but only with other StatTrak skins. You cannot mix StatTrak and non-StatTrak skins in the same trade-up. StatTrak trade-ups follow the same rules but produce StatTrak outputs, which are typically more valuable.

It depends entirely on the specific combination. Most random trade-ups lose money on average, but carefully researched combinations can have positive expected value. The key is finding cheap input skins from collections with expensive next-tier items. Use this simulator to test combinations before risking real skins.
