The Factory Must Grow.
In Factorio, efficiency is the only metric that matters. A "Spaghetti Base" might get you to blue science, but if you want to launch a rocket per minute (RPM), you need math. You need perfect ratios, balanced belts, and optimized fluid dynamics.
We created these Factorio Utilities to help you untangle your production lines. Calculate exactly how many assemblers you need to saturate a blue belt and solve your pipe throughput issues instantly.

Production Ratio Calc
Plan your factory backwards. Input "1000 Blue Circuits per minute" and see exactly how many Copper Cables, Red Circuits, and Assemblers you need.

Fluid dynamics are tricky. Calculate flow rate drop-off over distance to ensure your Nuclear Power plant gets enough water.
Check Flow →The Quest for Perfect Ratios
The core loop of Factorio is identifying bottlenecks. If your Green Circuit production is stalling, it's usually because you didn't calculate the Copper Cable ratio correctly (It's 3:2, by the way).
Our Production Calculator solves this by accounting for:
- Assembler Speed: An Assembler 1 (0.5 speed) is very different from an Assembler 3 (1.25 speed).
- Modules & Beacons: Adding Speed Module 3s changes the math entirely. We calculate the new throughput so you don't overbuild.
- Belt Saturation: It tells you if your output requires a Yellow (15 items/s), Red (30 items/s), or Blue (45 items/s) belt.
Solving the Pipe Throughput Mystery
Pipes in Factorio behave like real physics simulations. The longer the pipe, the lower the pressure (throughput). A single offshore pump produces 1200 water/second, but if you run that water through 200 pipes without a pump, the flow rate drops drastically.
Our Manifold Calculator helps you design nuclear reactors and oil refineries by telling you exactly where to place pumps to maintain maximum flow.

We are actively updating our database to include the new quality modules, elevated rails, and space platform mechanics introduced in the 2.0 expansion.
Yes. Remember that a pair of underground pipes (entry + exit) counts as only **2 pipe segments** for fluid calculations, regardless of the distance traveled underground. This is the secret to high-throughput fluid busses.
