A trade-up contract in Counter-Strike 2 is a feature that lets you exchange 10 skins of the same rarity for one skin of a higher rarity. In the case of Gloves and Knives you need just five red skins. After the recent update, this system became much more transparent and exciting. You can now predict the outcome more accurately and even plan which collections to target. Players use this system to craft better skins, including rare knives and gloves, without buying them directly from the market.

Here’s how it works: you choose 10 skins of the same rarity – for example, 10 Mil-Spec (blue) skins. After confirming the trade-up, the game gives you one skin of the next rarity level – in this case, a Restricted (purple) skin. The result can come from any collection included in your 10 skins, and each collection’s chance depends on how many of its skins you used.

How the CS2Locker Trade-Up Calculator Works

To make smarter trade-ups, many players use the CS2Locker Trade-Up Calculator, also known as the Free Trade-Up Simulator. It’s a tool that helps you see possible results before you spend your real skins in-game.

You simply pick five skins of the same rarity and enter their float values (the wear condition). The calculator then shows you all possible outcomes – skins of one rarity higher, within the same collections you used. It also displays the exact percentage chances for each possible skin.

For example, if half your inputs are from the Mirage Collection and half from the Vertigo Collection, your odds are split 50/50 between those two. Inside each collection, the chance is evenly shared among the higher-tier skins. This makes it easy to understand what you can expect from your contract.

Reverse Trade-Up: Plan Your Dream Knife or Gloves

Another useful feature of the CS2Locker calculator is the reverse trade-up option. It works in the opposite direction – instead of seeing what you’ll get, you can check what you need to craft a specific item.

If you’ve ever dreamed of a certain knife or gloves, the reverse trade-up shows which skins and collections are required to make that item possible. It’s a great way to plan your contracts and manage your inventory strategically.

Why Use a Calculator Before Trading

Trade-ups in CS2 are a mix of strategy and luck. Using a calculator helps you minimize risk and understand the odds before committing your skins. It’s especially helpful for expensive contracts, where one wrong collection can waste a lot of value.

Whether you’re a casual player trying to upgrade your loadout or a skin trader looking for profit, the Trade-Up Calculator is a safe and easy way to experiment without spending a single cent. You can test combinations, check float outcomes, and even prepare your next big crafting plan – including knives and gloves.

In short, trade-ups have become more advanced than ever, and with the help of tools like CS2Locker, every player can craft smarter and aim for their dream skin with confidence.
