⚠️ 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

Rebar is a ribbed steel bar used to reinforce advanced building materials and research. It is a key ingredient for crafting ashlar stone blocks (basalt, limestone, shale, sandstone, gneiss, granite), Reinforced Concrete, Sulfurcrete, and Modern Metallurgy Research Papers. Since it appears in many structural and research recipes, maintaining a steady supply of Rebar is practical for towns progressing into mid-to-late-game construction and technology.
