Satisfactory Calculator

How many finished items per minute the line should produce.
From the in-game recipe: how many items one craft cycle yields.
From the in-game recipe: how long one craft cycle takes at 100% machine speed.

Summary
4 machines at 15 items/min each produce 60 items/min against a target of 60.
Worked out from Rate balancing is elementary proportional reasoning: OpenStax, Elementary Algebra 2e, chapter 6 (ratios, rates and proportions).
The recipe figures are the ones you entered. This calculator carries no game recipe database, so it stays correct across patches and across games rather than quoting a number that may have changed.

How this is worked out

4 steps
  1. Crafts per minute per machine = 60 / 4 × 100% = 15.
  2. Output per machine = 1 per craft × 15 crafts/min = 15 items/min.
  3. Machines needed = 60 ÷ 15 = 4, so build 4.
  4. Iron Ore: 1 per craft × 15 crafts/min × 4 machines = 60 items/min.

Iron Ore: 60 items/min (60 for the exact target)
