Frequently Asked Questions

A trade up contract in Counter-Strike 2 allows you to trade skins of the same rarity tier for one skin of the next highest tier. For most rarities, you need 10 input skins. For Covert (red) to Knife/Glove trade ups, you only need 5 skins. The outcome is influenced by the float values and collections of the input skins.

Yes! Since October 2025, you can trade up 5 Covert (red) skins to receive a Knife or Glove. The input skins must be from cases that contain knives/gloves. StatTrak Covert skins will result in a StatTrak knife. This is one of the most exciting ways to potentially get expensive knives!

Our calculator uses the official CS2 trade up formula, factoring in the float values and collections of your input skins to provide accurate outcome predictions. It calculates the probability of each possible outcome, including knife/glove trade ups, and helps you find profitable opportunities.

The reverse trade up tool lets you select a desired skin (including knives and gloves), and it will show you all the possible combinations of input skins required to obtain it through a trade up contract. This is great for targeting specific high-value items like Ruby Doppler knives or the AWP Dragon Lore.

Yes, you can mix skins from different collections or cases. The outcome skin will be randomly chosen from the collections of the input skins you used, weighted by the number of skins from each collection. For knife/glove trade ups, all inputs must be from cases that contain gold items.

The float value is a number between 0 and 1 that determines the wear condition of a CS2 skin. A lower float value means a cleaner, less scratched skin (Factory New: 0.00-0.07), while a higher float value indicates more wear (Battle-Scarred: 0.45-1.00). Float values are crucial in trade up contracts as they affect the outcome skin's float.

Each marketplace has its own fee structure, user base, and regional focus. Steam Market charges a 15% fee, while third-party sites typically charge 2-10%. Buff163 prices are often lower due to the Chinese market, while Western sites may have higher prices but offer more convenience.
