Formula and worked example
Loss = bookings × no-show rate × (1 − refill share) × contribution
| Input | Example |
|---|---|

| No-show rate | 8 % |
| Contribution per attended booking | 80 |
| Share of missed slots refilled | 20 % |
| Calculated result | 768 per month |
Choose reliable inputs
Allow time for preparation, the service itself and cleaning up before the next appointment. For this salon calculation, use appointment history, service durations and supply costs and a consistent definition of one appointment.
- Stylist time: include the portion belonging to this appointment or reporting period, and record where the value came from.
- Consumables: include the portion belonging to this appointment or reporting period, and record where the value came from.
- Chair overhead: include the portion belonging to this appointment or reporting period, and record where the value came from.
Use the same currency for every money input. Do not mix weekly costs with monthly revenue, or count the same expense in both an itemised cost and allocated overhead.
Should a no-show loss use the full booking price?
Use contribution after costs that are avoided when the booking is missed, and account for successful slot refilling.
Assumes contribution is lost only on slots not refilled; fee revenue is excluded.
What if this input changes?
If monthly bookings rises by 10%, this example changes by 76.8 per month. This shows the effect of one change; it does not predict what will happen.
Open the calculator, save your baseline, then change the input supported by the least reliable estimate in your records. Compare both scenarios before committing to a price or capacity promise.
