Include preparation, paid attendance and room costs in teaching economics. Start with attendance records, teaching schedules and room costs. Each example below uses hypothetical values you can replace.
Class Attendance Break-Even
Find attendance needed to fund one class.
Required attendance = ceiling(class fixed cost / (fee − attendee cost))
Show example inputs and result
| Instructor and room cost per class | 150 |
|---|---|
| Fee per attendee | 25 |
| Variable cost per attendee | 3 |
Result: 7 attendees.
Compare the result with safe room capacity. Revenue per attendee must exceed variable attendee cost.
Open class attendance break-evenEffective Teaching Hourly Return
Include preparation and student administration when evaluating lesson pricing.
Hourly return = (fee − other costs) / ((lesson + preparation) / 60)
Show example inputs and result
| Fee per lesson | 50 |
|---|---|
| Lesson time | 60 minutes |
| Preparation and admin | 30 minutes |
| Other cost per lesson | 5 |
Result: 30 per hour.
Use your own preparation time. This is before personal taxes and excludes costs not entered.

Forecast service revenue from actual attendance assumptions.
Expected revenue = bookings × attendance rate × average collected price
Show example inputs and result
| Booked appointments | 100 |
|---|---|
| Attendance rate | 90 % |
| Average collected service price | 80 |
Result: 7,200 .
Excludes cancellation fees and variable costs. Attendance is an entered scenario, not a promise.

Reserve delivery capacity for variability before promising work.
Deliverable units = floor(hours × (1 − buffer) / hours per unit)
Show example inputs and result
| Available delivery hours | 640 |
|---|---|
| Hours reserved for disruption | 15 % |
| Hours per class place | 4 |
Result: 136 units.
The reserve is your scenario assumption; it is not a universal staffing recommendation.

For a fitness studio business, review instructor cost, rent, and class occupancy across the complete workflow. Use one consistent period and delivery unit: a class place. Compare the assumptions with recorded outcomes after delivery, then update the estimate.
