Choose reliable inputs
Connect teaching time, preparation, attendance and room capacity to each lesson or class. For this tutoring service calculation, use attendance records, teaching schedules and room costs and a consistent definition of one lesson.
- Teacher time: include the portion belonging to this lesson or reporting period, and record where the value came from.
- Preparation: include the portion belonging to this lesson or reporting period, and record where the value came from.
- Scheduling: include the portion belonging to this lesson 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 many appointments fit when turnaround is included?
Subtract breaks before entering available minutes. This model uses one identical service duration.
What if this input changes?
If available staffed minutes rises by 10%, this example changes by 0 appointments. 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.
