Accumulator — Factorio Production Calculator
Accumulator is crafted in the assembling machine in 10 seconds, producing 1 per craft from 2 × Iron plate, 5 × Battery. At 60 per minute you need 20 assembling machines, and the chain behind it draws on 4 raw resources: water, petroleum gas, iron ore, copper ore.
Production chain for 60 Accumulator / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Sulfuric acid | 6,000 | 2 | Chemical plant |
| Sulfur | 600 | 5 | Chemical plant |
| Iron plate | 540 | 28.8 | Furnace |
| Battery | 300 | 20 | Chemical plant |
| Copper plate | 300 | 16 | Furnace |
| Accumulator | 60 | 20 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Water | 21,000 |
| Petroleum gas | 9,000 |
| Iron ore | 540 |
| Copper 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.
Accumulator recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Iron plate × 2, Battery × 5 |
What the whole chain needs
60 accumulators per minute pulls in 5 intermediate products, and the whole tree comes to 92 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 21,000 per minute, which is 23.33 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 accumulator
1 base-game recipe consumes accumulator, sorted by how much each one takes:
- Satellite — 100 per craft
What accumulator is made from
- Iron plate — 2 per craft
- Battery — 5 per craft
FAQ
How many assembling machines do I need for 60 accumulators per minute?
20 assembling machines. One at standard speed produces 3 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 accumulator take?
At 60/min the chain consumes 21,000 water per minute, 9,000 petroleum gas per minute, 540 iron ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is accumulator needed for science packs?
Not directly. It feeds Satellite, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
