Efficiency module 3 — Factorio Production Calculator
Efficiency module 3 is crafted in the assembling machine in 60 seconds, producing 1 per craft from 4 × Efficiency module 2, 5 × Advanced circuit, 5 × Processing unit. At 60 per minute you need 120 assembling machines, and the chain behind it draws on 5 raw resources: petroleum gas, copper ore, iron ore, water, coal.

Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 197,250 |
| Copper ore | 98,700 |
| Iron ore | 53,550 |
| Water | 26,250 |
| Coal | 9,300 |
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 3 recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 60 s | 1 | Efficiency module 2 × 4, Advanced circuit × 5, Processing unit × 5 |
What the whole chain needs
60 efficiency module 3s per minute pulls in 11 intermediate products, and the whole tree comes to 14,019 machines across 3 machine types, fed by 5 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 197,250 per minute, which is 219.17 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.

FAQ
How many assembling machines do I need for 60 efficiency module 3s per minute?
120 assembling machines. One at standard speed produces 0.5 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 3 take?
At 60/min the chain consumes 197,250 petroleum gas per minute, 98,700 copper ore per minute, 53,550 iron ore per minute and 2 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is efficiency module 3 needed for science packs?
Not directly. It feeds Spidertron, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
