⚠️ 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.
