Efficiency module — Factorio Production Calculator
Efficiency module is crafted in the assembling machine in 15 seconds, producing 1 per craft from 5 × Advanced circuit, 5 × Electronic circuit. At 60 per minute you need 30 assembling machines, and the chain behind it draws on 4 raw resources: petroleum gas, copper ore, iron ore, coal.
Production chain for 60 Efficiency module / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper cable | 3,900 | 32.5 | Assembling machine |
| Copper plate | 1,950 | 104 | Furnace |
| Electronic circuit | 900 | 15 | Assembling machine |
| Iron plate | 900 | 48 | Furnace |
| Plastic bar | 600 | 5 | Chemical plant |
| Advanced circuit | 300 | 60 | Assembling machine |
| Efficiency module | 60 | 30 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 6,000 |
| Copper ore | 1,950 |
| Iron ore | 900 |
| Coal | 300 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Efficiency module recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 15 s | 1 | Advanced circuit × 5, Electronic circuit × 5 |
What the whole chain needs
60 efficiency modules per minute pulls in 6 intermediate products, and the whole tree comes to 295 machines across 3 machine types, fed by 4 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 6,000 per minute, which is 6.67 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses efficiency module
1 base-game recipe consumes efficiency module, sorted by how much each one takes:
- Efficiency module 2 — 4 per craft
What efficiency module is made from
- Advanced circuit — 5 per craft
- Electronic circuit — 5 per craft
FAQ
How many assembling machines do I need for 60 efficiency modules per minute?
30 assembling machines. One at standard speed produces 2 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does efficiency module take?
At 60/min the chain consumes 6,000 petroleum gas per minute, 1,950 copper ore per minute, 900 iron ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is efficiency module needed for science packs?
Not directly. It feeds Efficiency module 2, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
