Choose reliable inputs
Allow time for preparation, the service itself and cleaning up before the next appointment. For this nail salon calculation, use appointment history, service durations and supply costs and a consistent definition of one appointment.
- Technician time: include the portion belonging to this appointment or reporting period, and record where the value came from.
- Supplies: include the portion belonging to this appointment or reporting period, and record where the value came from.
- Station 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.
How much should price change when costs rise?
Enter a weighted increase across the costs included. This is a target-margin calculation, not a demand forecast.
What if this input changes?
If current assigned cost rises by 10%, this example changes by 92.5714 . 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.
