Class break-even and attendance planner

Enter venue hire for the complete booking, including paid setup and clearing time. Add other fixed costs allocated to the class, such as travel, equipment replacement and a share of recurring business costs. Enter costs that rise with each attendee separately.

The tool labels the result as surplus before owner pay. To model a desired payment for your time, add that amount to other fixed costs and record it in your notes; the resulting surplus is then after that allowance. Do not count the same allowance twice when comparing scenarios.

Contribution per attendee = amount received per attendee minus variable cost per attendee. Fixed class costs = venue cost plus other fixed costs. Break-even attendance = fixed class costs divided by contribution, rounded up. Revenue and surplus use the actual attendance scenario entered, not automatically the break-even figure.

Fictional example: a room costs £30, other costs are £12, and each attendee pays £12 with £0.50 variable cost. Fixed costs total £42 and contribution is £11.50. Four paying attendees cover those entered costs. At four attendees, revenue is £48, costs are £44 and surplus is £4 before owner pay and personal tax.

If the teacher also includes a £35 allowance for their time in other costs, fixed costs become £77 and seven paid attendees are needed. These figures illustrate the method; they are not recommended class prices or typical earnings.

Enter a capacity appropriate for the venue, activity, your competence and participant needs. Capacity is not the advertised standing occupancy of a hall. A calculator cannot determine how many people you can safely and effectively teach.

If calculated break-even exceeds the capacity entered, the tool highlights that the model cannot break even within that limit. Review the venue, cost allocation or service plan. Do not exceed safe capacity to repair a financial calculation.

If each attendee contributes zero or less and there are fixed costs, more attendance cannot cover those fixed costs at the inputs entered. The planner shows no positive-attendance break-even. Zero costs and zero contribution have an arithmetic break-even of zero, which says nothing about whether the activity is worthwhile.

A negative class surplus means the entered costs exceed the revenue. A small positive result may still be insufficient after preparation and other costs omitted from the model. This is planning arithmetic, not tax advice or a guarantee that people will book.

Try several attendance levels, including an underfilled class. Confirm venue cancellation terms and decide when you need enough paid bookings to proceed. Make the cancellation and refund process clear to participants before taking payment.

After the pilot, compare actual attendance, paid revenue, costs and working time with the model. Use those records to decide whether to change the timetable, improve the booking information or repeat the format. Do not assume an additional class will fill because one session worked.
