THE NUMBERS, EXPLAINED
How to use this calculator.
No-show statuses are observed, release delay is supplied policy and recovery probability is a scenario assumption.
Start with your inputs
Enter booked meeting durations (minutes), no-show indicator per booking (0 or 1), release delay for unclaimed room (minutes), probability released minutes are rebooked (%). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Booked meeting durations (minutes) | 60,90 |
| No-show indicator per booking (0 or 1) | 1,0 |
| Release delay for unclaimed room (minutes) | 15 |
| Probability released minutes are rebooked (%) | 50 |
A worked example
With the example inputs above, no-show booked minutes is 60. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| No-show booked minutes | 60 |
| Minutes releasable after delay | 45 |
| Expected recovered room-minutes | 22.5 |
How this is calculated
No-show booked minutes
Add full booked duration of no-show meetings.
Minutes releasable after delay
Deduct release delay from each no-show booking, floored at zero.
Expected recovered room-minutes
Apply the supplied rebooking probability to releasable time.
Symbols and units
- a
- Booked meeting durations (minutes)
- b
- No-show indicator per booking (0 or 1)
- c
- Release delay for unclaimed room (minutes)
- d
- Probability released minutes are rebooked (%)
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
No-show statuses are observed, release delay is supplied policy and recovery probability is a scenario assumption.
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?
No-show booked minutes; Minutes releasable after delay; Expected recovered room-minutes. 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: No-show statuses are observed, release delay is supplied policy and recovery probability is a scenario assumption.
Are my inputs stored or sent to AI?
