THE NUMBERS, EXPLAINED
How to use this calculator.
Location times include moving obstructing boxes and replacing them. Retrieves are independent; combined trips are not credited.
Start with your inputs
Enter expected retrievals by location, round-trip retrieval minutes by location. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Expected retrievals by location | 10,5 |
| Round-trip retrieval minutes by location | 3,8 |
A worked example
With the example inputs above, retrieval time by location (min) is 30, 40. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Retrieval time by location (min) | 30, 40 |
| Total retrieval workload (h) | 1.166667 |
How this is calculated
Retrieval time by location (min)
Multiply expected retrieval count by measured trip time at each location.
Total retrieval workload (h)
Sum retrieval minutes and divide by sixty.
Symbols and units
- a
- Expected retrievals by location
- b
- Round-trip retrieval minutes by location
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
Location times include moving obstructing boxes and replacing them. Retrieves are independent; combined trips are not credited.
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?
Retrieval time by location (min); Total retrieval workload (h). 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: Location times include moving obstructing boxes and replacing them. Retrieves are independent; combined trips are not credited.
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.
