Mechanics
In CS2, a trade-up contract accepts exactly 10 weapon skins of the same rarity and produces 1 skin of the next higher rarity. The output skin's float value is determined by the adjusted float formula: the average float of all 10 inputs is mapped into the output skin's condition range, producing a predictable wear result.
The output condition depends on where the average input float falls relative to the output skin's min and max float values. Lower-float inputs (closer to 0) tend to produce Factory New or Minimal Wear outputs; higher-float inputs (above 0.45) push toward Field-Tested, Well-Worn, or Battle-Scarred.
Profitability depends on three factors: (1) the cost of 10 inputs at current marketplace prices, (2) the expected value of the output distribution weighted by each skin's market price, and (3) the marketplace fees applied on both the buy and sell sides. This trade-up was calculated using live listing prices with all fees included.
