How to Trade Up to CZ75-Auto | Eco
CZ75-Auto | Eco drops from Horizon Case, so any contract that can produce it needs 10 Mil-Spec skins from that same case. Here is what the contract costs, what else it can land on, and the input float you need for each exterior.

The contract
10 inputs, all Mil-Spec, all from Horizon Case. Concentrating every input in one case is what keeps your odds at 20% — mixing cases splits the probability across both pools and lowers your chance at CZ75-Auto | Eco specifically.

Input float for each exterior
CS2 normalises float across a trade-up: each input’s float becomes a 0–1 position inside its own range, those are averaged, and the average is applied to CZ75-Auto | Eco’s range of 0.00–1.00. To land a given exterior, your ten inputs must average the normalised float below.
| Target exterior | Output float | Required avg. input float |
|---|---|---|
| Factory New | 0.0350 | 0.0350 |
| Minimal Wear | 0.1100 | 0.1100 |
| Field-Tested | 0.2650 | 0.2650 |
| Well-Worn | 0.4150 | 0.4150 |
| Battle-Scarred | 0.7250 | 0.7250 |
“Not reachable” means CZ75-Auto | Eco’s own float range never enters that exterior band — no combination of inputs can produce it.
What CZ75-Auto | Eco is worth right now
