⚠️ 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

Reinforced Concrete is a tier‑4 building block crafted from cement, rebar, and other materials, making it one of the strongest construction materials in the game. It is required for advanced industrial structures like the Computer Lab, Oil Refinery, and Pump Jack, which are essential for late‑game meteor defense and heavy industry. Because the Computer Lab is critical for coordinating the lasers that destroy the meteor, prioritizing reinforced concrete production can significantly accelerate your town’s end‑game progress.
