Know your Stardew Valley crafting costs before you build
Crafting often feels free because you gathered the materials yourself, but every ingredient has a sell value you give up. This calculator adds the true gold cost of each material so you can see whether a recipe is worth crafting, batching, or skipping in favour of selling raw.
How it works
For each material the subtotal is:
subtotal = quantity × per-unit value
The total crafting cost is the sum of all subtotals. If a recipe yields more than one finished item, the cost per output unit is:
cost per unit = total cost / output count
When you provide a finished sell price, profit per item is sell price − cost per unit, and total profit is that figure multiplied by the output count. Intermediate crafted parts roll in by entering their own crafting cost as the per-unit value.
Tips and example
Suppose a recipe needs 5 wood at 2g each and 1 coal at 15g, yielding 1 item that sells for 50g. Total cost is 5×2 + 1×15 = 25g, cost per unit is 25g, and profit is 50 − 25 = 25g. Always value gathered materials at their sell price so the profit figure reflects real opportunity cost, and recalculate whenever market prices or professions change your effective values.
