Decider combinator — Factorio Production Calculator
Decider combinator is crafted in the assembling machine in 0.5 seconds, producing 1 per craft from 5 × Copper cable, 5 × Electronic circuit. At 60 per minute you need 1 assembling machine, and the chain behind it draws on 2 raw resources: copper ore, iron ore.
Production chain for 60 Decider combinator / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper cable | 1,200 | 10 | Assembling machine |
| Copper plate | 600 | 32 | Furnace |
| Electronic circuit | 300 | 5 | Assembling machine |
| Iron plate | 300 | 16 | Furnace |
| Decider combinator | 60 | 1 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Copper ore | 600 |
| Iron ore | 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.
Decider combinator recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.5 s | 1 | Copper cable × 5, Electronic circuit × 5 |
What the whole chain needs
60 decider combinators per minute pulls in 4 intermediate products, and the whole tree comes to 64 machines across 2 machine types, fed by 2 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 600 per minute, which is 0.67 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.

FAQ
How many assembling machines do I need for 60 decider combinators per minute?
1 assembling machine. One at standard speed produces 60 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 decider combinator take?
At 60/min the chain consumes 600 copper ore per minute, 300 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is decider combinator needed for science packs?
Not directly. It feeds Selector combinator, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
