A craft’s real cost is more than its top-line materials — it includes every intermediate part you had to make first. This calculator totals a full bill of materials, including sub-components, so you know the true gold cost.
How it works
Each material contributes a line cost, and the total is their sum. Sub-components are handled by using their own crafting cost per unit in place of a market price:
line cost = quantity × unit cost
sub-comp = (sum of its inputs) / units produced ← enter as unit cost
total cost = Σ line cost (across every material and sub-component row)
Because a crafted sub-component’s unit cost already folds in its own inputs, the total automatically rolls up every layer of the recipe — no separate step needed.
Example and tips
A weapon upgrade needing 3 ore at 200 each, 2 crafted plates at 1,500 each (a
sub-component), and a 4,000 zenny forge fee totals 600 + 3,000 + 4,000 = 7,600.
To compare crafting versus buying a plate, enter its market price on one line and
its summed-input cost on another — the cheaper line cost wins. Always add the
forge fee as its own row so the total is genuinely all-in.
