Trade Up Contract Calculator
In Counter-Strike 2 (CS2) and CS:GO, the Trade Up Contract is one of the most exciting features. It allows players to combine 10 skins of the same rarity to receive one skin of a higher rarity. While it’s thrilling, the system is based on probabilities—meaning results can be uncertain and sometimes costly.
That’s where the Trade Up Contract Calculator comes in.
This tool helps you predict outcomes, calculate probabilities, and assess potential profit or loss before committing your skins to a trade up contract. Whether you’re a casual player or a serious trader, the calculator ensures you make informed decisions.

- Input the collection and market price of each skin you plan to use.
- Confirm Skin Rarity
- Ensure all skins are of the same rarity level (required for a valid trade up).
- Click “Calculate”
- The tool instantly shows:
- Possible output skins

Example Trade Up Calculation
Imagine you’re submitting 10 Restricted skins from two different collections:
- 5 skins from Collection A (average value: $2 each)
- 5 skins from Collection B (average value: $3 each)
The calculator will show:
- Potential outcomes (Mil-Spec skins from Collection A or B)
- Drop probabilities (50% chance for Collection A, 50% for Collection B)
- Expected value (EV) based on current market prices
Result:
- If Collection A’s Mil-Spec skin is worth $7
- And Collection B’s Mil-Spec skin is worth $15
The expected value (EV) might be around $11, meaning it could be a profitable trade.
