THE NUMBERS, EXPLAINED
How to use this calculator.
All kits have the same component recipe and components are freely interchangeable; no partial kit is counted as ready.
Start with your inputs
Enter component stock counts, components required per rental kit, booked complete kits. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Component stock counts | 10,8,20 |
| Components required per rental kit | 2,1,4 |
| Booked complete kits | 6 |
A worked example
With the example inputs above, complete kits currently available is 5. Change the inputs to explore your own scenario.

All kits have the same component recipe and components are freely interchangeable; no partial kit is counted as ready.
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?
Complete kits currently available; Component shortages for booked kits; Bookings not coverable with complete kits. 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.
