CS2 Trade-Up Calculator
1Choose the input rarity
All inputs must share one rarity; the outputs are one tier higher.
2Add the input skins and their floats
Pick skins from the catalog or your inventory, then set each float.
Select a rarity tier above to start building your trade-up.
Plan a trade-up before you sign the contract
This free CS2 trade-up calculator lets you plan any trade-up contract before you sign it in-game. Pick a rarity, fill the 10 input slots from valid collections, set each skin's float, and the simulator works out every possible output, its probability, the resulting output float and the expected profit. It also covers knife and glove trade-ups, so you can see your odds at a Covert or Extraordinary outcome.
FAQ
Is the CS2 trade-up calculator free?
Yes. The CS2 trade-up calculator and simulator are completely free. Build any trade-up contract, set floats, and see the odds and expected profit without signing in.
Can I calculate knife and glove trade-ups?
Yes. Select the Covert rarity to run a CS2 trade-up calculator for knives, or the Extraordinary tier for gloves. The simulator shows each possible knife or glove outcome with its probability and market price.
How does a CS2 trade-up contract work?
A trade-up takes 10 skins of the same rarity and returns one skin of the next rarity up. The output skin is picked at random from the collections you used, and its float is the average float of your 10 inputs scaled to the output skin’s float range.
What is the difference between a trade-up calculator and a trade-up simulator?
They are the same tool here. The calculator computes the exact output float and outcome odds, while the simulator lets you experiment with different skins and floats to find the most profitable CS2 trade-up before you commit in-game.
Can I share a trade-up or use skins from my inventory?
Yes. Save any calculation to get a share link that others can open and edit as a copy. Sign in with Steam to load your inventory and fill the input slots with skins you own.
Does it work for CS:GO trade-ups too?
Yes. CS:GO skins and collections carried over to CS2, so the same trade-up rules apply. Output prices refresh twice a day.
