Mini-session profit and capacity worked examples
Compare invented US outdoor and Canadian indoor mini-session events with completion, capacity, and cost differences.
Business question
How do schedule capacity, completed bookings, retained cancellation revenue, event costs, and working hours change these invented mini-session plans?
The existing calculator keeps capacity, bookings, completed paid slots, retained cancellation revenue, costs, fees, and work hours visible for two independent events.
Inputs
Start with allowlisted invented values.
- The US and Canadian events are independent invented scenarios, not a location comparison.
- USD and CAD remain display labels; no conversion or regional multiplier is applied.

Process
Reproduce the calculation in order.

Divide the bookable window by session plus turnaround minutes to establish slot capacity.
- 02
Calculate collected event revenue from completed bookings, add-ons, and any retained cancellation revenue.
- 03
Subtract fixed costs, variable completed-session costs, and modeled payment fees, then compare the result with entered work hours.

Interpretation
What the outputs do—and do not—show.
- Booked slots and completed paid slots are separate counts; a paid non-completion can affect both capacity reporting and retained revenue.
- The full-capacity view is a model boundary, not evidence that every slot can or will sell.
Limitations
Boundaries to keep visible.
- The examples do not model local demand, weather risk, sales tax, refunds beyond the entered retained amount, or client-specific fulfillment.
- Real event decisions need documented venue, labor, contingency, delivery, and cancellation assumptions.
