Why Float, Rarity and Collection Matter for Trade-Ups

In CS2 trade-up contracts, the output skin's wear is determined by a mathematical formula using each input skin's float value and float range. Lower input floats produce better output conditions, which often means significantly higher output prices.

The collection determines which skins can appear as output, and the rarity determines the tier. Understanding these mechanics is the key to finding profitable contracts.

Trade-Up Float Formula

adjusted_float = (input_float - 0.00) / (0.25 - 0.00)

When USP-S | Serum is used as a trade-up input, its float value is first normalized to the skin's specific float range (0.00 – 0.25). The adjusted float contributes to the average that determines output float.

Output Float Prediction

With 10× USP-S | Serum inputs at the same float, the output float for Covert skins in the The Arms Deal 2 Collection would be:

output_float = out_min + avg_adjusted_float × (out_max - out_min)
