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.

How to read float
«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.

One of this craft's two collections paired with another collection, same rarity. Click a variant to open its page with all the numbers. The variants may include a craft at a small loss: no more than 15% of the investment, if its most expensive outcome brings at least three investments after the fee and that outcome's price is confirmed by sales.

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 Anubis Collection and The Harlequin 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.
