Graveyard Keeper 2 Factory Power Calculator

Free Graveyard Keeper 2 factory power calculator: count conveyor belt demand vs carousel zombie supply, Belt Master, and large-network planning targets.

Fan-made planning helpers using fixed in-game rules (sums, power caps, and published item costs). Not affiliated with the game publisher. Always verify materials and power on your save after patches.

What counts toward factory power?

In vanilla Graveyard Keeper 2, carousel power feeds the conveyor network—not the crafting benches sitting on the side. Each occupied belt tile, splitter, underground segment, and supply station typically costs 1 power on the network you are planning. Enter those counts above, then compare the total to how many zombies you have walking carousels.

Each zombie on a carousel adds 7 power without Belt Master, or 10 power with Belt Master. The hard cap is five carousels with four zombies each—at most 140 supply (or 200 with Belt Master). If demand exceeds supply, belts stall even when machines and chests are wired correctly.

Large supplies factories often budget around ~200 belt demand as a planning target; that is not a game-enforced maximum, but it explains why mid-game lines feel fine while end-game grids freeze until you add carousels or remove belt tiles.

Power math only: add up conveyor, splitter, underground, and supply-station tiles, then compare to carousel zombies (7 power each, 10 with Belt Master). Workbench machines do not consume carousel power in vanilla GK2.

Carousel supply

Each zombie on a carousel adds 7 power (10 with Belt Master). Up to 5 carousels, 4 zombies each.

Belt Master perk (+3 per zombie)

Active carousels (1–5)

Zombies walking on carousels (total)

Belt network demand

Each belt tile, splitter, underground segment, and supply station costs 1.

Belt tiles

Splitters

Underground belts

Supply stations

Community planning target (optional, e.g. 200)

~200 demand is a common planning target for large supplies networks — not a hard in-game cap.

Setup checklist

Saved in your browser (LocalStorage).

Repair both broken carousels in the factory hall
Staff carousels (zombies only walk — they do not craft)
Prove one input → machine → output chest line before cloning
Set chest export filters (one item per outgoing belt)
Add conveyor chests between busy bench steps (manual grab buffer)
Count belt demand before adding more machines
Branch belts for town orders only after single-item lines are stable
Plan kit lines vs delivery crates after town progress (kits can still be sold)

How to count belts without double-counting

Count every conveyor tile that will exist when the line is finished, including corners and short bridges between chests and machines. Splitters and underground belts count as their own tiles. Do not add bench crafting stations into the demand field—they do not draw carousel power in the base rules this calculator uses.

When you extend a line, add only the new tiles to your running total. If you rebuild, reset the form or subtract removed segments so the demand matches the live factory.

For chest filters, splitter direction, and a first micro-line that does not jam, see the factory setup guide. To estimate structure materials for new buildings, use the building cost calculator.
