Crafting estimate at current listings
No real market: too few listings for this price to mean anything yet.
- Reagent cost (lowest listed)
- 633 gold57 silver
- Crafted item, lowest listed price
- 140 gold74 silver
- Auction House cut (5%)
- 7 gold3 silver
- Estimated profit at that listed price
- −499 gold86 silver
No real market: only 7 units across 5 auctions region-wide. With this little supply the lowest listing is one asking price rather than a market rate, so treat the estimate above as arithmetic, not an opportunity; a buyer at that price is not established.
- Evidence: 5 current listings holding 7 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 92% below its 30-day median of 1,700 gold79 silver, so this estimate rests on a listing far below its usual level.
- Quality: Calibrated Safety Switch comes in 3 quality ranks. This is the base comparison, rank 1 reagents against the rank 1 result; your skill and the reagents’ ranks decide the rank you actually get, which this estimate does not model. Each rank’s lowest listing is in the rank table below.
- Not included: the recipe also accepts 2 finishing reagent slots, which are not required and are left out of the cost.

Calibrated Safety Switch quality ranks
Calibrated Safety Switch comes in 3 quality ranks, and each rank is its own item on the Auction House. The recipe’s base crafting difficulty is 425.
| Rank | Item | Lowest listed price | Listings (US) |
|---|---|---|---|
| Rank 1 | Calibrated Safety Switch | 140 gold74 silver | 5 listings, 7 units |
| Rank 2 | Calibrated Safety Switch | 750 gold17 silver | 4 listings, 9 units |
| Rank 3 | Calibrated Safety Switch | 1,899 gold10 silver | 7 listings, 600 units |
The crafting estimate above is the base comparison: rank 1 reagents against the rank 1 result. Your skill and the reagents’ ranks decide which rank a craft actually makes, so a higher rank is never priced against rank 1 reagents here.
Calibrated Safety Switch: lowest listed price, last 30 days
The current lowest listing is 92% below its 30-day median. Over these 30 days the lowest listing moved more than tenfold, so a single snapshot, including the one the estimate uses, can sit far from typical.

Reading these numbers
At current lowest listed prices the 4 reagents for one craft of Calibrated Safety Switch cost 633 gold57 silver. Most of that is Arclight Capacitor - 1 at 395 gold each, 395 gold, 62.3% of the whole basket. Watch that one price and you have watched most of this recipe.
Break-even is 666 gold91 silver - below that listed price the craft loses gold once Blizzard’s 5% cut is taken. The crafted item’s lowest listed price is 140 gold74 silver, which does not clear it.
The crafted item currently lists for less than its reagents cost: −492 gold83 silver before fees, and the Auction House would still take 7 gold3 silver of a sale, so a craft loses 499 gold86 silver at these prices. At current listings, buying the crafted item costs less than making it. That is an estimated -78.9% return on the gold you put into reagents.
Listing depth right now: 7 units across 5 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 →
