Factorio Module Calculator for Productivity, Speed, Beacons and Quality
Use this Factorio module calculator workflow when a normal recipe ratio is not enough. Modules change crafting speed, productivity bonus, power draw and pollution, while beacons spread those effects across nearby machines. Start with the live calculator, then use the tables and examples below to sanity-check the result before rebuilding a factory block.
Last updated: June 10, 2026. Covers Factorio 2.0, Space Age quality modules, productivity modules, speed modules, efficiency modules and beacons.
Factorio Module Calculator Tool
Open the calculator, choose a recipe, then set machine tier, productivity modules, speed modules, beacon count, beacon modules and quality settings. The important outputs are machines required, ingredient demand, output rate, power consumption and whether transport can keep up.

Recommended inputs to set first
- Target output rate: items per second, items per minute or science per minute.
- Machine tier: assembler, furnace, chemical plant, foundry, electromagnetic plant or other Space Age machine.
- Module slots: productivity, speed, efficiency or quality modules inside each machine.
- Beacon setup: number of beacons, modules inside beacons and whether the layout is realistic.
- Transport and power checks: belts, inserters, fluids, trains and MW demand after modules.
Quick Answer: What Should a Module Calculator Tell You?
A useful Factorio module calculator should not only say that productivity is stronger or speed is faster. It should show how the module plan changes every connected number: machine count, ingredient consumption, byproducts, power, pollution and belt load.
- Productivity modules usually reduce raw material cost per output but slow the machine and increase power use.
- Speed modules and speed beacons reduce machine count, but they can raise ingredient demand and power spikes quickly.
- Efficiency modules are useful when power, pollution or early-game energy limits matter more than maximum output.
- Quality modules belong in Space Age quality planning; they trade speed for a chance at higher-quality items.
- Beacon math must be checked against the real layout, because theoretical beacon counts can exceed what fits around the machines.
Module Type Comparison
Choose the module based on the constraint you are solving. A factory that lacks copper needs a different answer from a factory that lacks building space or power.
| Module type | Best use | Calculator output to watch |
|---|---|---|
| Productivity module | Expensive intermediate products, science packs, labs and recipes that allow productivity. | Lower raw input per final item, slower machine speed, higher power draw. |
| Speed module | High-throughput blocks, beaconed builds and late-game compression. | Fewer machines, higher ingredient rate, higher power and possible transport bottlenecks. |
| Efficiency module | Early power-limited factories, pollution control and remote outposts. | Lower energy use and pollution, often less useful once power is abundant. |
| Quality module | Space Age quality item production and upcycling loops. | Quality probability, reduced speed, recycler loops and expected normal-quality output. |
| Beacon modules | Sharing speed or efficiency effects across many machines. | Effective speed bonus, MW demand, footprint and whether every machine receives the intended beacons. |
How to Use the Factorio Module Calculator
Start with one target recipe
Pick the recipe you are actually planning, such as processing units, low density structures, science packs, rocket parts or a Space Age intermediate.
Set the target rate
Use items per second for belts and machines, or items per minute for science goals. Keep one target unit consistent while comparing module builds.
Add machine modules first
Enter productivity, speed, efficiency or quality modules inside the machines before adding beacons. This keeps the base machine count understandable.
Add beacons realistically
Set the beacon count that your layout can actually support. A compact mall, a bus block and a late-game beacon grid will not share the same beacon coverage.
Check inputs, power and transport
After modules, re-check raw resources, belt count, fluid throughput, inserters, train delivery and power. A module plan that looks efficient can still bottleneck upstream.
Common Module Calculator Examples
Productivity in expensive recipes
For processing units or science packs, productivity modules can save large upstream resource chains. The calculator should show fewer raw ingredients per final item but more machines or beacon support.
Speed beacons in megabase blocks
Speed beacon builds are strong when space and UPS matter. The calculator helps compare a dense beaconed block against a larger unmoduled build with the same target output.
Efficiency modules for outposts
Remote mining or early power-limited builds may benefit from efficiency modules because lower power and pollution can matter more than maximum throughput.
Quality modules in Space Age
Quality modules change expected output rather than only speed. Use the calculator to estimate how many machines, recyclers and ingredients are needed for quality goals.
Module and Beacon Edge Cases
Most module mistakes happen because the calculator result is copied without checking recipe rules, layout limits or transport limits.
| Case | Risk | What to verify |
|---|---|---|
| Recipe does not allow productivity | The plan assumes a bonus the game will not apply. | Check whether the selected recipe accepts productivity modules. |
| Too many theoretical beacons | The output rate is based on a layout that does not fit. | Compare beacon count with the actual blueprint footprint. |
| Transport is unchanged | Machines can produce faster than belts, pipes or inserters can move items. | Recalculate belt lanes, fluid throughput and train delivery. |
| Power is ignored | Beaconed builds can overload a grid that worked before modules. | Check MW demand after modules and add margin. |
| Quality loops are treated as simple output | Expected quality items may require recycling and repeated crafting. | Model recycler loops and normal-quality byproducts separately. |
Need recipe chains after choosing modules?
Use the main calculator to trace the full ingredient chain, then return to this page when you need to compare module and beacon setups for the most expensive steps.
Factorio Module Calculator FAQ
What is the best module setup in Factorio?
There is no single best setup. Productivity modules are usually strongest in expensive allowed recipes, speed modules and beacons are strongest for compact high-throughput builds, efficiency modules help with power and pollution, and quality modules are for Space Age quality goals.
Should I use productivity modules or speed modules?
Use productivity modules when saving ingredients matters and the recipe accepts them. Use speed modules or speed beacons when machine count, footprint or throughput is the constraint. Many late-game builds combine productivity inside machines with speed modules in beacons.
Do beacons change ingredient consumption?
Speed beacons increase the effective crafting speed, so ingredient consumption per second rises with output. Productivity modules can reduce ingredients per final item, but the line still needs enough belts, fluids and trains to support the new rate.
Can I calculate quality modules with this page?
Yes. Use the embedded calculator for the live recipe data, then check quality probability, speed penalty, recycler loops and expected output. For deeper quality-specific planning, use the quality calculator guide.
Why does my module calculator result not fit in game?
The usual causes are unrealistic beacon coverage, a recipe that does not accept productivity, missing power margin, transport bottlenecks or using a different game version or mod set than the actual save.
