Required input float for each MAC-10 | Sakkaku wear
| Wear | Output float | Avg normalized input float | Cheapest route | Best chance |
|---|---|---|---|---|
| Factory New | Not possible — outside this skin's 0.21–0.79 float range | |||
| Minimal Wear | Not possible — outside this skin's 0.21–0.79 float range | |||
| Field-Tested | 0.210–0.380 | < 0.2931 | $1.44 | 20.0% |
| Well-Worn | 0.380–0.450 | ≥ 0.2931 and < 0.4138 | $3.48 | 8.0% |
| Battle-Scarred | 0.450–0.790 | ≥ 0.4138 and any | $0.80 | 20.0% |
The average is over every input's float normalized to its own range. Output float = 0.21 + average × 0.58.

How CS2 trade-up contracts work
Inputs & odds
10 skins of one rarity become 1 skin of the next rarity (Mil-Spec → Restricted → Classified → Covert). Since the October 2025 update, 5 Covert skins can become a knife or gloves from those skins' case. Each input collection gets its share of the odds (inputs from it ÷ total), split evenly across that collection's next-tier skins.
Float math
Every input float is normalized to its own skin's range — (float − min) ÷ (max − min) — and averaged. Each output's float is its min + average × (max − min), so a restricted-range skin like 0.10–0.20 can only land in the wears its range allows.
Prices, fees & freshness
Values are Steam Community Market averages from the snapshot dated on each page. Profit subtracts the ~13% Steam seller fee. StatTrak™ inputs give StatTrak™ outputs (knives only — gloves have no StatTrak™). Map collections outside weapon cases aren't in DropLabz's dataset yet.
Pick the skin you want in the reverse trade-up finder, check any contract in the trade-up calculator, or compare with opening cases on case ROI and knife odds.
