Eco Build List — Raw Materials Calculator

Build list 0 items

Item	Quantity

Nothing in your list yet — search above and add what you want to build.

Inventory 0 items

Already have some of what you need? Add it here — the calculator subtracts it from demand at the right point in the chain (e.g. having Advanced Circuits on hand means less Copper Wiring, Gold Wiring, etc. get crafted for them too).

Item	Quantity On Hand

Nothing entered — the calculator will assume you're starting from scratch.

Add something to your build list to see raw materials.

Items whose only available recipe needs a crafting table you don't have enabled. They're added to your list as-is instead of being broken down further.

Item	Quantity	Requires station

Nothing blocked — every item in the chain can be made with your enabled stations.

One tree per item in your build list, showing exactly which parent item pulls in each ingredient and how much. The same item can appear in several branches — that's expected, since e.g. Board is used by many different recipes.

Add something to your build list to see its component tree.

Every item touched anywhere in the chain, the recipe currently used for it, and its running total. Change the recipe/station for any item with multiple options.

Item	Type	Have	Still Need	Specialty	Recipe / Station

Labor (calories) needed for your current build list, split by role — since in a multiplayer game, whoever crafts the final item(s) is very likely a different person than whoever makes the intermediate materials or gathers raw resources.

Final crafting — the item(s) actually in your build list

Nothing to craft directly — your list is all raw materials.

Intermediate materials — everything crafted along the way

Total

Nothing intermediate — everything in your list is raw or made in one step.

Raw material harvesting (chopping, mining, etc.) isn't included in either total above — that's a separate "calories burned per swing" mechanic tied to tools, not to crafting recipes, and isn't tracked by this calculator yet.

Reference: every craftable item in the game (not just your current list), grouped by the specialty/skill required for its cheapest recipe. Use the filter to jump to a specialty.

Data parsed directly from the Eco server's recipe definitions (943 craftable items, 67 crafting stations, 60 with an Upgrade Module slot). A few notes: generic material categories (e.g. "any wood," "any vegetable") are resolved to one representative item for calculation purposes. Recipes with multiple simultaneous outputs (e.g. butchering an animal for meat + hide + wool) are tracked under their first-listed output only, so co-products of those recipes are treated as gathered/raw rather than craftable — this mainly affects food/hunting items, not building materials or tech. Reusable containers/molds (Clay Mold, Ceramic Mold, Barrel) are credited back automatically when a recipe returns them, so they're not double-counted as fully consumed — this is exact for Clay/Ceramic/Wooden Mold reuse and the Petroleum/Barrel refining loop; a handful of rarer byproducts (Ashlar stone-cutting scraps, Slag/Sulfur reprocessing) aren't credited due to how they sit in the calculation order, so those are still slightly over-counted. Crafting table upgrades: pick an installed Upgrade Module per station in the sidebar — it gives a flat 25% resource-cost reduction for recipes matching that module's specialty, and 20% for any other recipe at that table (this is the game's actual fixed reduction; there's no separate "level 2/3" for an installed module — the Basic/Advanced/Modern tiers just control which tables/specialties qualify, not the size of the discount).

Specialty Progression (Tech Tree)

How professions and specialties unlock each other. Pick a profession first (no prerequisites), then each specialty needs both its profession and, for all but the six tier-1 starters, a specific prior specialty at level 1. Some chains cross professions — e.g. Oil Drilling is a Scientist specialty but still needs the Engineer tree's Mechanics first.

Professions pick one or more to start, no prerequisites

Crafting Tables — Dimensions & Room Requirements

Which specialty (or specialties) each table is used for, its physical footprint (width × height × depth, in blocks), what power it needs (burnable fuel, mechanical, or electrical — and how much for the latter two), and the room it needs, if any — minimum enclosed volume and minimum average material tier. A table with no room requirement works fine outside; if there's a material tier requirement, the table needs to be enclosed by definition. This is a static game-data reference, independent of your build list.

Power Generation

Every power-generating structure in the game — renewable (wind, water, solar) and fuel-burning — with the specialty needed to build it, what type of power it outputs and how much, and its fuel needs if any.

Building Materials — Room Material Tier

Some crafting tables above need a minimum average material tier for their room. Use this to see what tier each building material contributes, then mix materials so your room's average meets what the table needs.
