Crafting calculator
Pick a recipe and a quantity. ForeverEcon totals the materials, and will follow every craftable input down to the raw material it comes from.

The raw list above assumes you craft Light Leather ×84, Medium Leather ×21, Iron Bar ×6, Heavy Leather ×4, Bronze Bar ×2, Gold Power Core ×2, Gyrochronatom ×2, Iron Strut ×2, Bronze Framework ×1, Copper Bar ×1, Gold Bar ×1, Tin Bar ×1 rather than buying them. Where an item can be made more than one way, the simplest tracked recipe is assumed.
Quantities come from the recipes themselves — 839 read out of the Forever client plus the verified Classic layer. A recipe's material list is a fact about the client. What it costs is a separate fact, measured from player auction scans rather than inferred from the recipe — and a material nobody has scanned stays blank. How the dataset is built.
