SatisfactorySatisfactory Calculator for production chains
The Satisfactory Calculator plans your production chain: enter a target item and quantity per minute to see every intermediate step, machine count, raw material requirement and byproduct. It’s free, requires no sign-up and runs in your browser.

- Assembler6×(6 exact)
“Exact” assumes a 100% clock speed. If you round up to whole machines, you need the number shown in bold (the last machine will run below 100%, or you can underclock them all accordingly).

How it works
How to use the Satisfactory calculator
No login, no setup: calculate directly in your browser.
Step 1
Select target item
Search the item browser by name or category and select the item you want to produce. Reinforced Iron Plate is selected by default.
Step 2
Enter target rate
Enter how many items per minute you need in the “Target (items/min)” field. Any value above 0 is allowed; calculations are capped at 100,000 per minute. The default is 30.
Step 3
Read the machine overview
The machine overview shows how many of each machine type you need to build, rounded up, with the exact value at a 100% clock speed in parentheses.
Step 4
Check raw materials and byproducts
“Raw materials required” shows how much ore, oil, or water is needed per minute at the source. If there are byproducts, the calculator lists them separately with their rates per minute.
Step 5
Explore the production chain
The “Complete Production Chain” table shows every intermediate step, its rate per minute, machine and machine count, down to the raw materials.

How the Satisfactory calculator works
Each recipe produces a fixed quantity per cycle in a fixed time. This gives a machine’s output at a 100% clock speed: output per cycle × 60 ÷ cycle time in seconds = items per minute. Divide your target rate by this value to get the exact machine count. The calculator does this for every step and works back to the raw materials.
Example using the default settings: an Assembler produces 1 Reinforced Iron Plate in 12 seconds, or 5 per minute. For 30 per minute, you need 6 Assemblers, plus 24 Constructors for Iron Plate, Screw and Iron Rod, 12 Smelters for Iron Ingot and 360 Iron Ore per minute.
If the result is not a whole number, the calculator shows the rounded-up count and the exact value in parentheses. For 1.5 Assemblers, build 2 and underclock one to 50% or set both to 75%. The calculator never automatically offsets requirements with byproducts; it lists them separately.
Scope
What the calculator covers and what it doesn't
Items covered
74 items in five groups: raw materials, basic parts, advanced parts, endgame components and byproducts, including Space Elevator parts and nuclear fuel rods.
Standard recipes from Satisfactory 1.0
The standard recipe for each item from the Satisfactory 1.0 game files (Docs.json). Alternate recipes cannot currently be selected.
Not included
Power consumption in MW, ammunition and Nobelisks, decorative items, and the SAM, Ficsite, and Quantum branches.

FAQ
FAQs about the Satisfactory Calculator
Quick answers about calculations, data sources, coverage and byproducts.
Production chain, machines, raw materials, and byproducts for your target rate.
Enter a target item and the desired quantity per minute. The calculator then shows the complete production chain down to the raw materials: every intermediate step with its rate, machine and machine count, an overview by machine type, raw materials needed per minute and the resulting byproducts.
Free, with no account or login required.
Yes, the calculator is free, and you need neither an account nor a login. Your target item and rate are processed only in your browser: no server request transmits or stores your inputs.
Target rate divided by the output of one machine at 100% clock speed.
At a 100% clock speed, a machine produces “output per cycle × 60 ÷ cycle time in seconds” items per minute. Dividing the target rate by this value gives the exact machine count, such as 1.5 Assemblers. Round up to build 2: either underclock one machine to 50% or set both to 75%.
From the Satisfactory 1.0 game files, not estimated from the wiki.
All recipes come from a community-maintained data export of the official Satisfactory 1.0 game files (Docs.json). No values were transcribed manually or estimated from the wiki.
74 items in the core production chain.
The calculator covers 74 items in five groups: raw materials, basic parts, advanced parts, endgame components and byproducts, from Iron Ore to Space Elevator parts and nuclear fuel rods. Ammunition, Nobelisks, decorative items and the SAM, Ficsite and Quantum branches are not included. Item names match the English game data, such as Reinforced Iron Plate.
Not currently. The standard recipe is used for each item.
No, not currently. For each item, the calculator uses the one standard recipe specified by the game. You cannot select alternate recipes.
They are listed separately and never used automatically.
Some recipes produce a second product. For example, the Refinery also produces Heavy Oil Residue when making Plastic or Rubber, while Alumina Solution produces Silica. The calculator lists these byproducts and their rates per minute separately instead of factoring them into the requirements. You decide whether to process them further or send them to the AWESOME Sink.
No, not currently.
No. Power consumption per machine is not part of the calculator, so it does not show estimated figures. For now, you need to plan your factory’s power requirements separately.
