Crafting to sell only pays off when you know the real material cost. This calculator lets you build a recipe from individual ingredients, scale it to a batch, and compare the total against a sale price so you can see margin before committing resources.
How it works
For each material the per-craft cost is unit price × quantity per craft. Summed
across all materials and adjusted for yield:
cost per craft = Σ (unit price × qty per craft)
cost per item = cost per craft / yield per craft
total cost = cost per craft × number of crafts
revenue = sale price × items × (1 − auction cut)
profit = revenue − total cost
Including intermediate components at their own crafting cost (not their market price) gives an accurate cost of goods.
Example and tips
If a recipe needs 3 herbs at 2 gold and 1 vial at 1 gold, each craft costs 7 gold. A batch of 20 costs 140 gold. If each sells for 12 gold with a 5% auction cut, you net 12 × 20 × 0.95 = 228 gold, a 88 gold profit. Always price intermediates by what they cost you to make, and re-check material prices often — auction markets move fast and a recipe that was profitable yesterday may not be today.
