CS2 Trade Up Contracts: How to Turn Skins into Profit
What Is a CS2 Trade Up Contract?
A CS2 trade up contract is a built-in feature that upgrades lower-tier skins into a higher-tier item.
You place ten skins into the contract and receive one random skin from the next rarity level. The output pool is determined by the collections represented in the contract, which is why traders carefully select their inputs.
For example:
AK-47 | Redline can appear from contracts using items tied to the Phoenix collection.

M4A1-S | Guardian is a common outcome in contracts involving the Huntsman collection.

AWP | BOOM is another classic trade-up target tied to older collections.

Not every outcome will be profitable, which is why calculating probabilities matters.
Can You Make Profit with CS2 Trade Up Contracts?
Yes—but only when the expected value (EV) favors the contract.
Successful traders usually analyze four things before pressing the confirm button:
Input Cost
Add up the total price of the ten skins. This is your investment.
Output Pool
Look at all possible outcomes from the collections involved. Some skins are worth far more than others.
Float Potential
The float of the output skin is calculated from the average float of the inputs. Lower floats can push results into Factory New or Minimal Wear, which often increases value.
Probability
Each collection in the contract contributes proportionally. More skins from one collection means higher odds of that collection’s outputs.
Pro tip: Always run contracts through a trade-up calculator before buying inputs. It’s the fastest way to see EV and float outcomes.
How to Use a CS2 Trade Up Contract
The process inside CS2 is straightforward.
Open your inventory.
Right-click a skin and choose “Use With Trade Up Contract.”
Add nine more skins of the same rarity.
Confirm the contract.
Watch the animation and receive your upgraded skin.
Once completed, the new skin appears in your inventory with a float determined by the inputs.
Strategies Traders Use for Better Trade Ups
Control the Collection Odds
If all ten skins come from one collection, your output will always come from that same collection.
Many traders use 9 skins from a target collection and 1 cheaper filler skin to control probabilities while lowering costs.
Target Valuable Outputs
Some collections contain one particularly desirable skin that raises the overall EV of the contract.
Examples traders often analyze include collections that can produce skins like:
AK-47 | Redline
M4A1-S | Guardian
AWP | BOOM
Even if these aren’t guaranteed wins, they anchor the value of the contract.
Use Low Float Inputs
If you want a Factory New result, you need low-float inputs. The average float determines the outcome.
For example:
10 skins around 0.02 float often produce FN outputs.
Higher floats push results toward Field-Tested or Well-Worn.
Run Multiple Contracts
Individual contracts are volatile. Traders often run several identical contracts to smooth out the variance.
Note: Prices and liquidity change—check current offers at the time of reading.
Are Trade Ups the Only Way to Get Rare Skins?
No. Trade ups are just one path.
Rare skins like AWP | Dragon Lore historically appeared through extremely specific high-tier contracts tied to particular collections. But players can also obtain skins through:

Case openings
Marketplace purchases
Trading with other players
Trade ups remain attractive because they let players convert cheap skins into higher-tier items without opening cases.
Key Takeaways
CS2 trade up contracts exchange 10 same-rarity skins for one higher-rarity skin.
The output collection depends on the skins used in the contract.
The average float of inputs determines the output wear.
Profit depends on expected value, probabilities, and input costs.
Smart traders analyze contracts before committing skins.
FAQ
Are CS2 trade up contracts profitable?
They can be, but only if the expected value of the possible outputs exceeds the cost of the inputs. Many contracts are negative EV without careful planning.
Do floats matter in trade ups?
Yes. The average float of the ten input skins determines the float of the output skin, which affects the final wear tier (FN–BS).
Can you mix StatTrak skins in trade ups?
No. A contract must contain either all StatTrak skins or all non-StatTrak skins.
How do collections affect trade ups?
The possible output skins come from the collections represented in the contract. More skins from a specific collection increase the odds of receiving skins from that collection.
Are trade up calculators necessary?
They’re not required, but most traders use them to estimate probabilities, float outcomes, and expected value before running a contract.
