What is this tool?

Turns a simple craft ratio into a shopping list: given how many inputs one craft consumes, how many outputs it produces, and how many finished items you want, it calculates craft actions required, total materials needed, and any surplus from rounding up. Applies to in-game crafting systems and real-world batch recipes alike — not tied to any specific title. Critical crafts, bonus yields, and failure rates are not modeled. Not affiliated with any specific game or publisher.

How to use it

  1. Enter inputs consumed and outputs produced per craft action.
  2. Enter the desired final output quantity.
  3. Read craft actions needed, materials needed, total output, and surplus.
