⚠️ 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

Iron Concentrate is a processed form of iron ore used as an intermediate ingredient in smelting, yielding Iron Bars, Steel Bars, and Cast Iron Plaque. It is produced by several concentration recipes and is stored as a solid block that stacks to 10 and is carried on your back. Stockpiling a steady supply is essential for any smithing operation, as it directly feeds metal production without the bulk of raw ore.
