An estimate from the market at the time of the measurement: cheap lots with the needed float may have been bought out or relisted — this is a check, not a forecast. “Check floats on Steam” shows the real price now.

The float limit is tighter than the markup table — less than 30% of the wear window fits. The purchase will cost at least the shown number of times more; how much more — no data, so the investment is “at least” and the profit is “at most”.

UMP-45 | K.O. Factory (Factory New) × 2 6% of the wear window fits at least ×2.21 3152.46 → 6966.94 ₽

MP9 | Latte Rush (Field-Tested) × 1 6% of the wear window fits at least ×2.16 1028.48 → 2221.52 ₽

MP9 | Latte Rush (Minimal Wear) × 7 6% of the wear window fits at least ×2.55 20730.50 → 52862.77 ₽

Markup — analysis table from lot books 25–26.09.2026: how many times the N cheapest lots with the needed float cost more than the cheapest lot of the wear; it depends on what share of the wear window fits and on the number of pieces.

Mix in a collection

Items of this craft's collections of the right rarity fit: The Fever Collection and The Train 2025 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 is its share in the chances. Your items are counted at market price in the full profit — you could sell them; separately shown is how much money you need to buy the rest now.

Third collection add one more to the craft's pair — it may pay more

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 the five most promising exactly.

How to read these numbers

«No higher than» — a guarantee, not a wish. The limits are calculated together: take all items at the upper bound at once — you get exactly what's shown. Take better — you get better.

f' — the same float, scaled to 0–1 by the skin's own range. Same as on csfloat.

Fees. The seller gets the listed price divided by 1.15, not multiplied by 0.85 — the fee is included in the buyer's price.

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 you'll get it in seven days: during the week the price will move, and the number shown is an estimate at calculation time, not cash in hand.

Prices are conservative. Sales are counted at the lower of the lot price and the sale price. Purchases — at the cheapest lot, and that is a lower bound: buying ten you climb the order book. «Check floats on Steam» shows the real purchase price.
