CSGO & CS2 Weapon Case Stats & ROI

The case index is what it costs on Steam to hold one of every tracked case. A case joins the total on the day it first trades and keeps its last price on days it does not trade. Each band uses that case’s color from the Steam sales chart. Terminals are left out.

CS2 case ROI is Bulk’s estimated expected-value ratio for classic cases: the expected market value of a random drop divided by (reference case price + key cost). The default price source is CSFloat. It is an average model, not the return of one opening, and it is not guaranteed profit.

The Best case ROI list on this page ranks tracked cases by the CSFloat estimate. You can also sort the cases table by Unbox ROI and switch the price source. Rankings come from cached marketplace feeds and move when those prices move.

Steam sales are units sold on the Steam Community Market, taken from Bulk’s price-history cache. The chart can also show dollar volume: each day’s price times that day’s units. The Highest Steam sales list uses the previous complete UTC week. The cases table uses the window you select: day, week, month, or 3 months. These figures are not sales on other marketplaces.

Active cases are in the weekly care-package drop pool. Armory cases are sold through the Armory. Discontinued cases are no longer in those drops. Status comes from Bulk’s catalog, not a live read from Valve on each page load.

Open a case from this database. Its page lists tracked drop-table skins and specials by rarity when the contents feed is available. Those outcomes are the same pool used in the ROI estimate.
