Reading these numbers
At current lowest listed prices the 4 reagents for one craft of Impeccable Cogwheel cost 100 gold22 silver. Most of that is Entropy Enhancer - 1 at 86 gold53 silver each, 86 gold53 silver, 86.3% of the whole basket. Watch that one price and you have watched most of this recipe.
Break-even is 105 gold49 silver - below that listed price the craft loses gold once Blizzard’s 5% cut is taken. The crafted item’s lowest listed price is 8 gold, which does not clear it.
The crafted item currently lists for less than its reagents cost: −92 gold22 silver before fees, and the Auction House would still take 40 silver of a sale, so a craft loses 92 gold62 silver at these prices. At current listings, buying the crafted item costs less than making it. That is an estimated -92.4% return on the gold you put into reagents.
Listing depth right now: 15 units across 6 auctions region-wide. Depth separates a market price from a single asking figure, but listings are not sales, so read it alongside the estimate.
Costs use each reagent’s lowest listed price; the estimate is the crafted item’s lowest listed price, times the items one craft makes, minus those reagents and Blizzard’s 5% sale cut. Listings are asking prices, not sales. Recalculated every snapshot and left blank rather than guessed when a price is missing. How we estimate crafting profit →
