What this contract can return: a knife or gloves
Share = (1 ÷ inputs with a pool) ÷ finishes in that input's case pool, added across inputs. Output float = outMin + average of the inputs' floats, each scaled inside its own skin's range (average 0.5300), times (outMax − outMin). Prices are the cheapest listing across the 8 markets for the normal (non-StatTrak) skin at the output wear.

Trade-up questions
How does the CS2 knife trade-up work?
Since 22 October 2025, five Covert skins return one knife or pair of gloves, taken from the case pool of one of the inputs. Only Covert skins from cases that have a knife or glove pool qualify. Five StatTrak Covert skins return a StatTrak knife; StatTrak gloves do not exist.
Which knives and gloves can I get?
The result comes from the knife and glove pool of the case that one of your inputs comes from. Choose the case above to see its full pool and the price of every finish. Mix skins from several cases and each case adds its own pool to the result.
How is the share of each knife and glove worked out?
For the 5-Covert contract each input contributes one fifth, split across the finishes in its case pool. Valve does not publish any weighting inside a pool, so equal weights are assumed, which is the community standard. Unpainted (vanilla) knives are not linked to cases in the catalogue, so a real pool can hold a few more finishes than shown.
How is the output float calculated?
Each input float is first scaled inside that skin’s own float range, the scaled values are averaged, and the average is placed inside the output skin’s range. Averaging the raw floats is the most common mistake: a skin capped at 0.45 counts differently from one that runs to 1.00. Low-wear inputs cost more, and worn inputs pull every result towards Battle-Scarred.
Can I use Souvenir or StatTrak skins as inputs?
Souvenir skins have been accepted in contracts since 22 May 2026, can be mixed with normal skins, and the output is always a normal skin. Normal and StatTrak skins cannot be mixed in one contract. This calculator covers normal and Souvenir inputs.
Why can I not use a skin I just received?
Skins that arrive in a Steam trade are trade-protected for 7 days and cannot go into a contract until the protection ends. The unlock calendar shows the exact time.
