THE NUMBERS, EXPLAINED
How to use this calculator.
Identical orders with divisible staff effort; simultaneous equipment limits and queues between slots are excluded.
Start with your inputs
Enter orders per pickup slot, active preparation (minutes/order), staff preparing orders, pickup slot length (minutes). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Orders per pickup slot | 12 |
| Active preparation (minutes/order) | 3 |
| Staff preparing orders | 2 |
| Pickup slot length (minutes) | 15 |
A worked example
With the example inputs above, whole-order slot capacity is 10. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Whole-order slot capacity | 10 |
| Workload utilization (%) | 120 |
| Orders beyond slot capacity | 2 |
How this is calculated
Whole-order slot capacity
Divide staff-minutes by work per order and round down.
Workload utilization (%)
Compare required staff-minutes with available staff-minutes.
Orders beyond slot capacity
Subtract whole-order capacity from assigned orders.
Symbols and units
- a
- Orders per pickup slot
- b
- Active preparation (minutes/order)
- c
- Staff preparing orders
- d
- Pickup slot length (minutes)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Identical orders with divisible staff effort; simultaneous equipment limits and queues between slots are excluded.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Whole-order slot capacity; Workload utilization (%); Orders beyond slot capacity. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Identical orders with divisible staff effort; simultaneous equipment limits and queues between slots are excluded.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
