Reagent cost, the crafted item's lowest listed price and the estimated profit at that price, from current US Auction House listings - recalculated every snapshot.
Crafting estimate at current listings
No real market: too few listings for this price to mean anything yet.

Thin market: the crafted item’s lowest listing comes from very few current listings and sits far out of line with reagent cost. Treat this estimate as unverified until more listings accrue.
- Evidence: 21 current listings holding 236 units of the crafted item in the US region. We see listings, not sales, so how many sell and at what price is unknown.
- Outlier: the crafted item’s lowest listing is 414 times its 30-day median of 1 gold45 silver, so this estimate rests on a listing far above its usual level.
- Items per craft: the game’s spell data creates 10 per craft, so the listed value of one craft is that many times the lowest listed price.

Reading these numbers
At current lowest listed prices the 1 reagent for one craft of Cobalt Skeleton Key cost 90 gold56 silver.
Break-even is 95 gold32 silver per craft, 9 gold53 silver per item at 10 items a craft - below that listed price the craft loses gold once Blizzard’s 5% cut is taken. The crafted item’s lowest listed price is 600 gold, which clears it.
At that listed price the gross margin before fees is 5,909 gold44 silver; the Auction House would keep 300 gold of a sale, leaving 5,609 gold44 silver. That is an estimated 6194.2% return on the gold you put into reagents, after the cut has taken 5.1% of the gross.
Listing depth right now: 236 units across 21 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 →
