Cost calculation

1. Components

Each block definition lists the components needed to build it. The blueprint's components are the sum over all known blocks. Mass is the sum of the components' masses (an empty ship, no cargo or ammo).

2. Ingots

Assembler recipes turn ingots into components. Recipes are normalised to "inputs per one result":

Steel Plate  ←  21 Iron Ingot           (vanilla)

For every component: ingots += count × input per unit ÷ assembler efficiency.

• Assembler efficiency is the world's assembler setting: Realistic = 1, x3 = 3, x10 = 10.
• If a recipe needs another product that has its own recipe (a modded part, a hydrogen bottle, …), that product is broken down further first. Loops between recipes are stopped after 16 levels.

3. Ore

Refinery recipes turn ore into ingots:

Iron Ingot  ←  1 / 0.7 = 1.4286 Iron Ore

For every ingot: ore += amount × ore per ingot ÷ yield.

Only real ores end up in the ore list; anything else a modded refinery recipe consumes is left out.

Worked example

10 steel plates, realistic assembler, no yield modules:

components : 10 Steel Plate
ingots     : 10 × 21           = 210 kg Iron Ingot
ore        : 210 × 1.4286      = 300 kg Iron Ore

With an x3 assembler the ingots become 70 kg; with 4 yield modules the ore becomes 150 kg.

Copy and CSV

Copy puts all three lists on the clipboard tab-separated (paste straight into Excel or Google Sheets). CSV saves Type,Item,Amount rows; ingots and ore are in kg.
