Factory Configuration
Choose a recipe, target, machine, modules, beacons, quality, and logistics.
Calculation History
Formula Used
Effective Crafting Speed = Machine Speed × Quality Multiplier × Effective Speed Multiplier Crafts per Second = Effective Crafting Speed ÷ Recipe Crafting Time Output per Second = Crafts per Second × Products per Craft × (1 + Productivity) Required Machines = Target Output per Second ÷ Output per Second per Machine Ingredient Rate = Required Crafts per Second × Ingredient Quantity Rounded Surplus = Rounded Machine Output − Target Output
How to Use This Calculator
Select the target recipe and production mode. Enter the required output rate. Choose its matching time unit.
Select a machine and quality level. Add valid modules and beacon settings. Review warnings before using results.
Enable chain expansion for raw resources. Mark imported materials as external. Export the finished factory plan.
Example Production Data
| Example | Recipe | Target | Suggested machine | Useful result |
|---|---|---|---|---|
| Science starter | Automation Science Pack | 60/min | Assembling Machine 2 | Machine count and ore chain |
| Circuit bus | Electronic Circuit | 900/min | Assembling Machine 3 | Copper cable ratio |
| Rocket factory | Rocket Fuel | 30/min | Chemical Plant | Oil and fuel demand |
| Custom mod | Custom Recipe | Any rate | Custom Machine | Editable crafting values |
Frequently Asked Questions
What does a production ratio represent?
It compares machine counts between connected stages. Balanced ratios reduce shortages and excess output. Rounded ratios remain practical for layouts.
Why are exact machines fractional?
Exact values describe ideal continuous production. Real factories need whole machines. The calculator shows resulting overproduction.
How is productivity applied?
Productivity increases recipe output without increasing inputs. Speed penalties still affect crafting throughput. Caps prevent unrealistic settings.
Can I calculate modded recipes?
Choose the custom recipe option. Enter crafting time and ingredients. Select the custom machine when needed.
What are external items?
External items stop further chain expansion. Use them for imports or unlimited fluids. They appear as raw requirements.
Why does the machine warning appear?
The selected machine category may differ. Custom configurations can override normal limits. Always verify the in-game recipe.
How are beacons estimated?
The calculator uses transmission and diminishing settings. These values support flexible planning scenarios. Adjust them for your version.
What does belt utilization mean?
It compares output against belt capacity. Higher values indicate less spare throughput. Add belts before capacity is exceeded.
Can configurations be saved?
The page stores settings in your browser. Saved values remain on the same device. JSON exports provide portable backups.
Does the calculator create blueprints?
It creates a planning summary only. Use results while designing actual blueprints. Confirm placement and inserter behavior manually.
