CSGO to CS2 Trade Up Contract Differences
Trade-up contracts have been a core feature since CSGO and continue in CS2. The mechanics are the same: 10 skins of one rarity produce 1 skin of the next tier, with output float determined by a normalized average formula. TradeUpX helps you find contracts where the expected output value exceeds your input cost after Steam's 13% fee.
Find Profitable Trade-Up Contracts →CSGO Trade-Up Contracts in CS2
The trade-up contract system transferred directly from CSGO to CS2 with identical mechanics:
- 10 input skins of the same rarity tier
- 1 output skin of the next higher rarity from the input collections
- Output float calculated using the normalized average formula
- StatTrak inputs produce StatTrak outputs
All CSGO collections and skins remain valid for trade-ups in CS2. Use the TradeUpX scanner to find profitable contracts across all collections.
Key Metrics for Trade-Up Contracts
- EV (Expected Value): Average profit across all possible outputs, accounting for probability and Steam fees
- ROI: EV as percentage of input cost — the primary ranking metric in TradeUpX
- Output Float: Predicted from the normalized float formula
- Steam Fee: 13% deducted on every sale (5% Steam + 8% CS2)
Getting Started with Trade-Up Contracts
New to trade-ups? Start with Mil-Spec to Restricted contracts (€10–50 total cost) to learn the mechanics. Graduate to Restricted to Classified for the best profit-to-risk ratio.
Use the TradeUpX tools page for float calculators, Steam fee estimates and ROI checks. Browse all collections to understand which skins are available at each rarity.
