Calculate production chains and resource needs for Factorio and other factory-building games.
Factorio Calculator
Factorio Calculator helps players calculate factory production and plan resource flows in the game.
About Factorio Calculator
Factorio Calculator is a web tool for planning factories in the game Factorio. It calculates the production and resource flows needed to produce selected items, using the game's recipes. The homepage lists the calculator as updated to game version 2.0.55 on 2025-06-17.
Users can set options such as modules, beacons, the mining productivity bonus, planets, and how rates are displayed per second, minute, or hour. Clicking an item's icon in the Factory tab removes that item's dependencies from the solution, which is useful when some ingredients are shipped in from elsewhere. The Factory tab also shows the pipe lanes needed for fluid throughput. The homepage does not list pricing details.
Key features
- Calculates factory production rates and resource flows from Factorio recipes
- Handles oil product recipes where items can come from multiple recipes
- Supports modules and beacons in factory calculations
- Includes the mining productivity bonus introduced in version 0.15
- Calculates with exact rational numbers instead of floating-point arithmetic
- Excludes an item's dependencies to model ingredients shipped in from elsewhere
Best for: Factorio players who want to plan factory production rates and resource requirements before building.
Good for
- Uses bigint rationals for calculations rather than floating-point arithmetic
- Supports multiple simultaneous outputs in a single solution
- Covers oil products, modules, beacons, and the mining productivity bonus

Factorio Calculator FAQ
What does clicking an item's icon in the Factory tab do?
It omits that item's dependencies from the solution. This models a factory that receives one or more ingredients from elsewhere. Clicking the icon again restores the dependencies.
How do I interpret the pipe numbers on the Factory tab?
Pipe throughput is inversely proportional to pipe length, so longer pipes need more parallel lanes. A display such as "[pipe] × 7 ≤ 47" means seven parallel lanes, each up to 47 segments long. The minimum pipe length setting defaults to 17, which corresponds to 1200/s, the output rate of an offshore pump.
