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 | Silver’s range of 0.00–0.08. 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 | 0.4375 |
| Minimal Wear | 0.0750 | 0.9375 |
| Field-Tested | — | not reachable |
| Well-Worn | — | not reachable |
| Battle-Scarred | — | not reachable |
“Not reachable” means CZ75-Auto | Silver’s own float range never enters that exterior band — no combination of inputs can produce it.
What CZ75-Auto | Silver is worth right now
Worth comparing against the contract cost above before you commit: buying the skin outright is frequently cheaper than rolling for it.
| Exterior | Price | vs. contract cost |
|---|---|---|
| Factory New | $3.12 | +$0.02 |
| Minimal Wear | $4.29 | +$1.19 |
