Static planner
Sandustry Production Planner
Use this after the line physically works. Pick a starter scenario, replace the numbers with values you verify in your current game version, then scale the chain and check the likely bottleneck before expanding.
Choose a scenario or enter verified ratios, then plan the rows you want to compare.
How to use it safely
Stabilize one stage first
Clear output space, confirm the right input reaches the machine, and watch byproducts before trusting any ratio math.
Replace template numbers
The scenario rows are planning placeholders. Use your own observed input and output values for the current Early Access version.
Scale only after the warning makes sense
If the planner points at Water, Wet Sand, transport or Residue, fix that physical bottleneck before adding machines.
Trust gate
Trust the planner only after the physical line already works at small scale. The calculation answers “how much input would this observed ratio need”; it does not prove a machine is receiving the right material, that output space is clear, or that the row is an official data row.
Measured input and output come from the same stable stage.
The stage ran long enough that a short random output swing is not driving the result.
Byproduct movement stayed visible during the sample.
The next action is a physical fix when the bottleneck warning points outside ratio math.
Best use case
Editable ratio rows help after a physical line is already stable and the numbers come from your own observed run.
Do not use it as a recipe database
The planner is not publishing official recipe numbers or guaranteed machine throughput. If the factory is failing physically, fix input, transport, output, or byproduct flow before trusting the math.
Featured Questions
When should I use the production calculator in Sandustry?
Use it after one small stage already runs cleanly and you have observed input and output values from that stage.
Can this calculator tell me why a factory is broken?
No. It can organize ratio planning, but it cannot prove whether the real problem is blocked output, bad input, transport, or byproduct backup.
Should I trust the template scenarios as official numbers?
No. They are editable planning starters. Replace them with values you verified in your current game version.
When the bottleneck is not ratio
Output space is full or buried.
Transport arrives in bursts or jams.
Input is dry, mixed or missing.
Byproducts cover the machine or next stage.
