Splitter — Factorio Production Calculator
Splitter is crafted in the assembling machine in 1 seconds, producing 1 per craft from 5 × Electronic circuit, 5 × Iron plate, 4 × Transport belt. At 60 per minute you need 2 assembling machines, and the chain behind it draws on 2 raw resources: iron ore, copper ore.
Production chain for 60 Splitter / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 960 | 51.2 | Furnace |
| Copper cable | 900 | 7.5 | Assembling machine |
| Copper plate | 450 | 24 | Furnace |
| Electronic circuit | 300 | 5 | Assembling machine |
| Transport belt | 240 | 2 | Assembling machine |
| Iron gear wheel | 120 | 2 | Assembling machine |
| Splitter | 60 | 2 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 960 |
| Copper ore | 450 |
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.
Splitter recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 1 s | 1 | Electronic circuit × 5, Iron plate × 5, Transport belt × 4 |
What the whole chain needs
60 splitters per minute pulls in 6 intermediate products, and the whole tree comes to 94 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 960 per minute, which is 1.07 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 splitter
1 base-game recipe consumes splitter, sorted by how much each one takes:

What splitter is made from
- Electronic circuit — 5 per craft
- Iron plate — 5 per craft
- Transport belt — 4 per craft
FAQ
How many assembling machines do I need for 60 splitters per minute?
2 assembling machines. One at standard speed produces 30 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 splitter take?
At 60/min the chain consumes 960 iron ore per minute, 450 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is splitter needed for science packs?
Not directly. It feeds Fast splitter, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
