How to use this tool

  1. Enter the measured quantities and planning assumptions in the displayed units.
  2. Run the calculation, then compare the result with your available capacity or actual records.
  3. Change one assumption at a time to compare operating scenarios.

Try this example

{
  "total": 100,
  "small": 25,
  "medium": 45
}

Accuracy and scope

Uses floor allocation for small and medium; all rounding residual goes to large. Enter a whole order quantity.
