⚠️ Eco v0.14 is coming — the next major update reworks upgrade modules, so some of these numbers will change. They reflect the current version. What’s changing →
  • Simpler tiers: the 1–4 tiered upgrades become a single Basic / Advanced / Modern upgrade each.
  • Permanent upgrades: a module placed in a workstation is permanent — no more swapping lower tiers out as you progress.
  • Power transitions: a module can change a station’s power type/draw (e.g. a Modern upgrade moves a sawmill from mechanical to electrical power).
  • Talent-integrated: modules now use the same bonus/talent system — any talent benefit (power, labor cost, recipe unlocks) can come from a module.
  • Cheaper to upgrade: with the multi-tier parts gone, fully upgrading a workstation costs significantly less.

We’ll update this calculator shortly after the update releases.

Notes

The Rolling Mill is a placed crafting station used to shape steel into structural and decorative items such as corrugated steel, doors, shelves, and signs. It requires placement inside an enclosed room of at least Tier 3 quality with 24 m³ of free volume, meaning you need advanced building materials and furnishings to use it efficiently. Stocking a community Rolling Mill with steel sheets and bars lets other players access these components without needing the specialty themselves, which speeds up industrial construction.
