    Introduction

    This Factorio calculator helps you plan your factory. Tell it what items you want to make and how many you need per minute. It will figure out the rest. You'll see how many machines to build, what raw resources you need, and how much power your factory will use.

    The tool supports both the base game (v1.1) and the Space Age DLC. You can pick your assembler tier, furnace type, and mining drill. You can also add modules and beacons to see how they change your production. The calculator shows a full production chain from finished items all the way down to raw ores and fluids.

    Use it to find bottlenecks before you build. Check belt loads, pipe limits, and power draw in one place. This tool makes ratio math simple and fast.

    How to Use Our Factorio Production Calculator

    Enter the items you want to produce and set up your factory settings. The calculator will tell you how many machines you need, what raw resources to gather, how much power you will use, and the full production chain for your factory.

    Item: Type the name of the item you want to craft. Pick from the dropdown list. The base game ruleset lists every item that a recipe in Factorio makes or uses.13 The Space Age ruleset adds every item of the Space Age expansion.14 Click "Add Item" if you want to produce more than one item at a time.

    Quantity: Enter how many of that item you want to produce. This is tied to the rate unit you pick next to it.

    Rate Unit: Choose whether your quantity means items per second, per minute, per hour, or full blue belts.

    Game Version / Ruleset: Pick "Base Game (v1.1)" or "Space Age DLC (v2.x)" to match the version of Factorio you play.

    Default Assembler: Choose which assembling machine your factory uses. Higher tiers craft faster and have more module slots.

    Furnace Type: Pick the furnace used for smelting recipes like iron plates and steel. Electric furnaces allow modules.

    Mining Drill: Select the drill type used to mine raw ores from the ground.

    Global Module Preset: Apply the same module to every machine that has open slots. Choose speed, productivity, or efficiency modules at any tier, or a mixed preset.

    Beacons per Machine: Enter how many beacons affect each machine. Set this to 0 if you do not use beacons.

    Beacon Module: Pick which speed module fills your beacons. Each beacon holds two modules.15 In the base game (v1.1) ruleset, each beacon shares half of its modules' bonus with nearby machines.4 In the Space Age (v2.x) ruleset, each beacon passes on 1.5 times its modules' bonus, divided by the square root of the number of beacons reaching the machine.3 Beacons also pass on the extra power use of their modules.

    Display Rate Unit: Choose how results are shown across the calculator (per second, per minute, per hour, or in full belts).

    Use Byproducts as Inputs: Check this box to mark leftover outputs, such as the heavy and light oil from advanced oil processing, as available for other recipes instead of waste. Machine counts are not reduced by them.

    Show Machine Ratios: Check this box to see simplified build ratios between machines in your production chain.

    Recipes used: When an item in your chain can be made by more than one recipe, such as petroleum gas from basic or advanced oil processing, pick the recipe you use under Recipes used.

    Calculate: Press this button to run the calculator and see your full results. You can also press Enter in any field.

    Reset: Press this button to clear all your settings and start over with the defaults.

    Factorio Production Calculator

    Factorio is a game where you build factories. You mine raw materials, craft them into parts, and use those parts to make more complex items. Every item in the game has a recipe. Each recipe takes time and needs specific ingredients. As your factory grows, figuring out how many machines you need gets hard fast.

    This Factorio calculator solves that problem. You tell it what item you want to produce and how many you need per minute. It then works backward through every recipe in the chain. It counts how many assemblers, furnaces, chemical plants, and mining drills you need. It also shows you the exact rate of every intermediate item, from copper cable all the way down to raw ore.

    How Factorio Production Chains Work

    Most items in Factorio are not made in one step. For example, an advanced circuit needs electronic circuits, plastic bars, and copper cable.7 Each of those ingredients has its own recipe with its own ingredients. Copper cable needs copper plates.8 Copper plates are smelted from copper ore. This creates a tree of dependencies called a production chain. One item at the top can require dozens of machines producing different parts below it.

    Modules and Beacons

    Factorio lets you place modules inside machines. Speed modules make machines craft faster.5 Productivity modules give you bonus output from the same ingredients.5 Efficiency modules lower power use.5 Beacons are buildings that share module effects with nearby machines.3 Each beacon holds two modules.15 Before version 2.0, each beacon gave half of its modules' bonus to every machine in range.4 Since version 2.0, each beacon passes on 1.5 times its modules' bonus, divided by the square root of the number of beacons reaching the machine.3 Using the right mix of modules and beacons can cut the number of machines you need by a large amount.

    Why Machine Ratios Matter

    If one machine makes parts faster than the next machine can use them, items pile up and your factory stalls. If it makes parts too slowly, the next machine sits idle. Getting the right number of machines at each step keeps everything flowing. This is called ratio balancing. It is similar to measuring overall equipment effectiveness in real-world manufacturing. Every machine needs to run at the right speed to keep the production line moving. Doing the math by hand takes time, especially when modules change crafting speeds. This calculator does all that math for you instantly.

    Belts, Pipes, and Throughput

    Items move around your factory on transport belts. Each belt tier has a maximum speed. Yellow belts carry 15 items per second, red belts carry 30, and blue belts carry 45.1 The Space Age DLC adds the turbo transport belt, which carries 60.2 Fluids like petroleum gas and sulfuric acid move through pipes, which have their own flow limits. This calculator checks your item rates against these limits and warns you when a single belt or pipe is not enough.

    Frequently asked questions

    How do I add more than one item to produce at the same time?

    Click the "Add Item" button below the first item row. A new row will appear where you can type a different item name and set its own quantity and rate unit. The calculator will combine all items into one shared production chain and merge any ingredients they have in common.

    How are beacon effects calculated?

    Each beacon holds two modules of the type you pick.15 In the base game (v1.1) ruleset, each beacon shares 50% of its modules' bonus with every machine in range.4 A beacon holding two Speed Module 3 (+50% speed each) therefore gives each nearby machine +50% speed. In the Space Age (v2.x) ruleset, each beacon passes on 1.5 times its modules' bonus, divided by the square root of the number of beacons reaching the machine.3 Four beacons holding Speed Module 3 then give +300%. Beacons pass on the extra power use of their modules too. Set the number of beacons per machine and the beacon module type in the configuration section. The calculator adds all beacon bonuses to each machine's effective crafting speed.

    What does the belt load column mean?

    The belt load column shows how much of a transport belt's capacity your item rate uses. For example, ×0.5 on a blue belt means you are using half of that belt. If the number goes above 1.0, you need to split the items across multiple belts. The calculator picks the smallest belt tier that can handle the load and warns you if even the fastest belt is not enough.

    Why do I see a pipe overflow warning for fluids?

    In the base game (v1.1) ruleset the calculator warns above 1,200 units per second. In that version, how much a pipeline carries depends on how many pipes sit between two pumps, and a run of 17 pipes carries 1,200 units per second.12 Since version 2.0, fluid inside one pipeline has no flow limit, but each input or output connection can pass at most 6,000 units per second, and about 4,200 in practice.6 The Space Age (v2.x) ruleset warns above that 4,200. If your production needs more fluid than a single pipe can carry, the calculator shows an overflow warning. To fix this in-game, split the fluid across multiple pipes or add pumps to boost flow.

    What changes when I switch to the Space Age DLC ruleset?

    Switching to Space Age DLC (v2.x) updates the belt tier list. The base game has yellow, red, and blue belts. Space Age adds the turbo transport belt (60 items/s).2 This affects belt load calculations and overflow warnings throughout the results. The ruleset also uses the version 2.0 recipes: a low density structure takes 15 seconds, rocket fuel 15 seconds and solid fuel from light oil 1 second.10 In Space Age a rocket part takes one processing unit, one low density structure and one rocket fuel.11 Version 2.0 has no rocket control unit, and the calculator does not model quality. Every recipe of the base game and the Space Age expansion is available, including the new planets' items.14 Recipes that only the foundry, electromagnetic plant, cryogenic plant, biochamber, crusher or recycler can make use that machine, and those machines' built-in productivity bonus applies where a recipe allows productivity.

    How is the power draw calculated?

    Each electric machine has a base power cost in kilowatts, for example 75 kW for an Assembler 1, 150 kW for an Assembler 2 and 375 kW for an Assembler 3.9 The calculator multiplies this by the energy consumption modifier from your modules and beacons. Speed and productivity modules increase power use.5 Efficiency modules reduce it.5 The total is summed across all machines and shown in the Factory Summary. The power breakdown chart shows which machine types use the most energy.

    What does the pollution number mean?

    Most machines in Factorio produce pollution, which spreads across the map and attracts enemy attacks. The calculator adds up the pollution per minute of every machine, mining drill and pump in your build, from each machine's base pollution rate and your module settings. The rocket silo and the offshore pump produce none.15 In the Space Age ruleset, the crusher produces none, and the biochamber and the captive biter spawner each take 1 pollution per minute out of the air, so they lower the total.16 Higher pollution means more frequent and stronger enemy waves, so this number helps you plan defenses.

    What does the machine ratio number mean?

    When you check "Show Machine Ratios," each item gets a simplified ratio number. These numbers show the relative proportion of machines needed. For example, if iron gear wheels show ratio 2 and iron plates show ratio 3, you need 2 gear assemblers for every 3 plate furnaces. This helps you build balanced production blocks.
