CS2 Trade-Up Calculator — Find Profitable Contracts
Stop guessing which trade-up contracts are profitable. TradeUpX scans every CS2 collection in seconds, calculates expected value after Steam fees, and ranks results by ROI. Free, no account needed.

A trade-up calculator evaluates every possible 10-skin contract across all CS2 collections and tells you which ones are profitable. Instead of manually checking prices, float ranges, and output probabilities, the calculator does it all instantly.
- Scans all collections simultaneously — no manual guesswork
- Calculates EV (expected value) — the average return you can expect
- Applies Steam's 13% marketplace fee — shows real take-home profit
- Considers float values — output wear affects price significantly
- Ranks by profit percentage — best deals always on top
How TradeUpX Differs from Other Calculators
Most trade-up calculators require you to manually select 10 skins and then show you the outcome. TradeUpX does the opposite:
- Select a rarity path (e.g. Restricted → Classified)
- Click Start Scan
- Get a ranked list of every profitable contract across all collections
You don't need to know which collections are good — the scanner finds them for you. It also supports Mixed Float mode to target specific output wears, and Inventory Lock to automatically build the best contracts from your own inventory.
Understanding EV (Expected Value) in Trade-Ups
Expected Value is the statistical average outcome of a trade-up contract if you could run it infinite times. It accounts for every possible output skin, weighted by probability.
Example: A contract with 3 possible outputs — a €50 skin (40%), a €30 skin (40%), and a €10 skin (20%) — has an EV of €34.
If the 10 input skins cost €20 total, your ROI is 170% (€34 / €20). After Steam's 13% fee, your net EV is €29.58, giving a real ROI of 148%.
TradeUpX does this math for every combination and shows you only the profitable ones.
Which Rarity Path Should You Choose?
- Mil-Spec → Restricted: Best for beginners. Low cost (€10–50), lower ROI ceiling (120–180%).
- Restricted → Classified: Most popular. Balanced risk/reward (€30–150 cost, 130–220% ROI).
- Classified → Covert: High risk, high reward. Expensive inputs (€100–500), potential 200–500% ROI.
- Industrial → Mil-Spec: Micro-budget entry (€2–15). Learn the mechanics with minimal risk.
