THE NUMBERS, EXPLAINED
How to use this calculator.
Single product; customer order counts are whole sales packs. Production occurs only in whole minimum batches; excess units remain unallocated.
Start with your inputs
Enter customer orders in packs, units per sales pack, units per minimum production batch. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Customer orders in packs | 3,5,2 |
| Units per sales pack | 6 |
| Units per minimum production batch | 24 |
A worked example
With the example inputs above, ordered product units is 60. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Ordered product units | 60 |
| Production batches | 3 |
| Excess production units | 12 |
How this is calculated
Ordered product units
Add customer packs and multiply by units per pack.
Production batches
Round required units divided by minimum batch size up.
Excess production units
Subtract order units from whole-batch production.
