Conveyor Belts & Buildings
Quick reference for Satisfactory’s building tiers, belt throughput, and power generation. Always match your belt tier to your production output to avoid bottlenecks.
| Building / Item | Value | Notes |
|---|---|---|
| Mk.1 Conveyor Belt | 60 items/min | Starting tier, good for 1 Constructor |
| Mk.2 Conveyor Belt | 120 items/min | Early game backbone |
| Mk.3 Conveyor Belt | 270 items/min | Mid-game tier |
| Mk.4 Conveyor Belt | 480 items/min | Late mid-game |
| Mk.5 Conveyor Belt | 780 items/min | Late game |
| Mk.6 Conveyor Belt | 1,200 items/min | Fastest — for heavy outputs |
| Coal Generator | 75 MW @ 15 coal/min | +45 m³ water/min |
| Fuel Generator | 150 MW @ 12 fuel/min | Uses packaged or piped fuel |
| Nuclear Power Plant | 2500 MW @ 0.5 rods/min | +240 m³ water/min, produces waste |
| Geothermal Generator | ~150 MW average | Variable output, zero fuel |
| Power Shard OC Scaling | P = P₀ × (clock/100)^1.322 | Non-linear power cost for overclock |
Satisfactory Calculator FAQ
Everything you need to know about planning your factory in Satisfactory Update 1.0.
Divide your target output (items per minute) by the production rate of a single machine. Always round up to the next whole number since you cannot build a fraction of a building. For example, if you need 45 Iron Plates per minute and a Constructor makes 20/min, you need ceil(45/20) = 3 Constructors. This calculator does the rounding and overclocking adjustments for you automatically.
A single Coal Generator produces 75 MW of power and consumes 15 coal per minute plus 45 m³ of water per minute. Clock speed overclocking scales both power output and fuel consumption linearly — a 200% overclocked Coal Generator produces 150 MW but burns 30 coal/min. Fuel Generators produce 150 MW on 12 fuel/min, and Nuclear Power Plants produce 2500 MW on 0.5 Uranium Fuel Rods/min plus 240 m³ water/min.
The Mk.6 Conveyor Belt is the fastest, with a maximum throughput of 1,200 items per minute. Mk.5 belts handle 780/min, Mk.4 handle 480/min, Mk.3 handle 270/min, Mk.2 handle 120/min, and Mk.1 belts handle 60/min. Always ensure your belt tier can handle the combined output of all machines feeding into it, or your production will bottleneck.
Overclocking a building between 1% and 250% scales its production speed and power consumption linearly for output, but power draw uses the formula: Actual Power = Base Power × (Clock Speed / 100)^1.321928. This means doubling clock speed doubles output but increases power draw by roughly 2.5×. You need Power Shards to overclock — 1 shard for up to 150%, 2 shards for up to 200%, and 3 shards for up to 250%.
Work backwards from your final product. For each item in the chain, multiply the target rate by the ingredient ratio, then divide by the per-machine production rate to get the number of machines. Sum up all raw ore and resource inputs. This calculator traces the full chain — enter a target end product and it will break down every raw material needed per minute.
Alternate recipes often dramatically improve efficiency. For example, ‘Steeled Frame’ replaces Reinforced Iron Plates with Steel Beams, massively reducing iron ore usage. ‘Solid Steel Ingot’ lets you skip Iron Ingots entirely for Steel production. Always check alternate recipes in your Hard Drive unlocks before scaling up production — this calculator shows standard recipes, but you can manually adjust input rates for alternate recipe ratios.
Standard power draw at 100% clock: Constructors use 4 MW, Smelters use 4 MW, Foundries use 16 MW, Assemblers use 15 MW, Manufacturers use 55 MW, Packagers use 10 MW, Refineries use 30 MW, Blenders use 75 MW, and Particle Accelerators use 500–1,500 MW depending on recipe. Always build a 10–25% power buffer to prevent brownouts when machines spin up.
Yes. Underclocking (below 100%) is a powerful optimisation tool. Because power consumption scales with a 1.322 exponent, running two Constructors at 50% clock speed uses significantly less power than one at 100% while producing the same output. This trick is especially useful for machines that only need to match the throughput of a slower belt or downstream consumer.
