⚠️ 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

Crushed Basalt is a fine gravel used as a key ingredient for high-tier construction and infrastructure, including Stone Roads, Asphalt Concrete, and Reinforced Concrete. It is also utilized in the creation of Garden Ponds and Bloomeries. To maximize efficiency, players should ensure it is produced by a specialist to reduce the labor and resource costs associated with its recipes.
