The Harlequin Collection + The Safehouse Collection

Mil-Spec Grade → Restricted

Prices by float: this craft was not checked against the market at night (only the best are) or there were not enough listings. The numbers below are at average prices. «Check floats on Steam» will count by live listings right now.

Average profit +240.20₽

Invest 641.13₽

Average return 881.33₽

ROI +37.5%

Chance of profit 90%

If buying now (with float)

invest at least 1 652.05₽ · profit at most −770.72₽ (−46.6%) · chance of profit at most 0%

The estimate is made from the market at the time of the nightly check. Since then cheap listings with the needed float may have been bought or relisted. The «Check floats on Steam» button shows the current price.

The float window is very narrow: less than 30% of the wear range fits. The markup was not measured for such a case. The purchase will cost at least the stated number of times more. How much more is unknown, so the investment is shown as “at least” and the profit as “at most”.

UMP-45 | Warm Blooded (Factory New) × 1 8% of the wear range fits at least ×2.16 72.60 → 156.82 ₽

Five-SeveN | Silver Quartz (Factory New) × 9 8% of the wear range fits at least ×2.63 568.53 → 1 495.23 ₽

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.

8% of lots fit ≈ enough for 1 contract · medium (estimate)

Price understated: Only 8% of listings fit, and listings with a rare float cost more. The calculation uses the average price regardless of float, the real purchase will cost more.

Mix in a collection

Items of this craft's collections of the right rarity fit: The Harlequin Collection and The Safehouse 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.

Similar 25 crafts almost like this one

One of three things counts as similar. The same set with a different wear of cheap outcomes: profit and investment differ by less than 0,5%. The same nine items with a different tenth: profit differs by no more than 10%, investment by 20%. The same main half, whose outcomes make the profit, with a different filler: profit lower by no more than a quarter, investment cheaper by no more than a quarter.

How to read these numbers

«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.

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.
