CS2 Trade-Up Guide
CS2 Trade-Up Simulator — Test Before You Buy
Why risk real money on a trade-up you haven't tested? Use TradeUpX to simulate any contract and see every possible outcome, probability, and expected return before buying a single skin.

Why Simulate Before Trading
A trade-up simulator shows you the complete picture before you commit any money:
- Every possible outcome: See all skins you could receive and their probabilities
- Expected profit/loss: Know the mathematical expectation before buying
- Float predictions: See exactly what wear condition each output would have
- Risk assessment: Understand the variance — will you need 5 or 50 contracts for reliable profit?
How TradeUpX Simulates Contracts
The scanner functions as a comprehensive simulator:
- Evaluates every possible input combination across all collections
- Calculates output floats using the exact CS2 formula
- Looks up current market prices for every possible output
- Computes probability-weighted expected value
- Deducts Steam's 13% fee
- Ranks results by profitability
Each result in the scanner is effectively a simulation of that trade-up contract. Click any result to see the full breakdown of outcomes and probabilities.
Reading Simulation Results
Key metrics in every simulated trade-up:
- Total Cost: What you'd pay for all 10 input skins
- EV (Expected Value): Average return after Steam fees
- ROI %: Return on investment (EV / Cost × 100)
- Output list: Every possible output skin with wear, price, and probability
- Avg Float: The adjusted input float that determines output wear
Only act on contracts where you're comfortable with ALL possible outcomes, not just the best one.

Frequently Asked Questions
Is the trade-up simulator free?
Yes. TradeUpX is completely free. Simulate as many contracts as you want without spending anything.
How accurate is the simulation?
Very accurate. It uses the exact CS2 float formula and current market prices. The main source of error is price changes between simulation and actual purchase.
Can I simulate with my own inventory?
Yes. Upload your inventory CSV to the Inventory Lock tool to simulate trade-ups using only skins you already own.
