Before you burn a stack of rare materials, this calculator tells you exactly what a craft will cost. Add each ingredient with its quantity and price, include a crafting fee, and see the full per-item and batch totals so you can decide whether to craft or just buy the finished item.
How it works
Crafting cost is a simple weighted sum. For each material row with quantity
qty and unit value unit, the contribution is qty × unit. The full formula
is:
material cost = Σ (qty_i × unit_i)
per-item cost = material cost + crafting fee
batch total = per-item cost × number of items
The tool keeps each material as its own editable row so you can model recipes of any size, swap prices as the market moves, and immediately see the impact on your bottom line.
Example and notes
A recipe needing 10 iron ore at 5 each, 4 leather strips at 12 each, and 2 magic
dust at 40 each costs 50 + 48 + 80 = 178 in materials. Add a 25 crafting fee
and the per-item cost is 203. Crafting 5 of them totals 1,015. Compare that
per-item figure against the finished item’s sell price to know whether crafting
turns a profit or just sinks resources. For crafted sub-components, enter their
finished cost as the unit value so the total rolls up correctly.
