Covert → knife or gloves · Items in the contract: 5About the craftCraft 3321511 · ways to build: 3StatTrak™ craft. Inputs and outcome are StatTrak: a normal item won't do here, and the outcome sells at the StatTrak price, which differs from the price of the normal item.A contract of five Covert. The outcome is a knife or gloves from the inputs' collection, and it has many outcomes: the chance of a particular item is therefore small, and what counts is the average over all outcomes.The Steam fee is included.

how many times more the lots with the needed float cost
StatTrak™ M4A1-S | Mecha Industries (Battle-Scarred) × 2100% of the wear range fits×1.08253.80 → 272.96 $
StatTrak™ M4A4 | Desert-Strike (Field-Tested) × 1100% of the wear range fits×1.0339.23 → 40.44 $
StatTrak™ M4A4 | Desert-Strike (Battle-Scarred) × 2100% of the wear range fits×1.0189.30 → 90.38 $
The markup is taken from a check of Steam 25–26.09.2026 listings. It shows how many times the needed number of cheapest listings with a fitting float cost more than the cheapest listing of this wear. It depends on the width of the float window and on the number of items.
«No higher than» — is a guarantee. The limits are calculated together: take all items with the float at the upper bound and you get exactly the result shown. With a lower float the result will be better.
f′ — the same float, brought to 0–1 by the skin's own range. CSFloat counts the same way.

I already have items
Enter their float and the site will pick what to buy
Items of this craft's collections of the right rarity fit: The Gamma Collection and The Huntsman Collection — and of the mixed-in collection: enter its items with float, your own or ones you want to buy. Its share in the set equals its share in the chances. Your own items are counted in the profit at market price, because you could sell them. The money needed to buy the rest is shown separately.
Third collection
Add a third collection to the craft's two and see whether it gets more profitable
All splits of inputs across three collections are tried (1/1/8, 5/3/2 and the rest) and all outcome wears. The best set is shown for each collection. “Find the best” first quickly scores all collections and then calculates exactly the five best by the quick score.
How to read these numbers
Fees. Steam adds 15% to the seller's price, so the seller gets the listing price divided by 1,15. Multiplying by 0,85 is wrong.
The outcome can only be sold after a week. Inputs bought on Steam go into the contract right away. The outcome can also be crafted further without waiting, but Sell it is possible only after seven days. Over a week the price may change, so the amount shown remains an estimate at calculation time.
Prices are conservative. Sales are counted at the lower of the listing price and the sale price. Purchases are counted at the cheapest listing, which is a lower bound. You cannot buy ten at that price: each next listing costs more. «Check floats on Steam» shows the real purchase price.
