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
At current lowest listed prices the reagents cost more than the crafted item lists for: an estimated loss of 3 gold24 silver per craft.

- Evidence: 122 current listings holding 2,163 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 98% below its 30-day median of 2 gold71 silver, so this estimate rests on a listing far below its usual level.
- Items per craft: the game’s spell data creates 3 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 2 reagents for one craft of Blue Firework cost 3 gold39 silver. Most of that is Heavy Leather - 1 at 2 gold85 silver each, 2 gold85 silver, 84.1% of the whole basket. Watch that one price and you have watched most of this recipe.
Break-even is 3 gold56 silver per craft, 1 gold18 silver per item at 3 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 5 silver, which does not clear it.
The crafted item currently lists for less than its reagents cost: −3 gold24 silver before fees, and the Auction House would still take 75 copper of a sale, so a craft loses 3 gold24 silver at these prices. At current listings, buying the crafted item costs less than making it. That is an estimated -95.8% return on the gold you put into reagents.
Listing depth right now: 2,163 units across 122 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 →
