Understanding Per-Guest Cost After Attendance Falls

This is an invented planning exercise, not a customer event or testimonial.

Background and constraints

A fictional board-game social originally expected 16 people, but only 12 confirm after the room has been paid for. The organizer needs to explain why per-person cost rises despite lower food spending.

Planning process

The host updates guest count to 12 and keeps the fixed room payment unchanged. Food actuals are reduced to the confirmed order. The result shows 408 spent, 192 remaining and an actual cost of 34 GBP per confirmed guest.

Result explanation

The room cost does not fall when attendance changes. Dividing 408 by the earlier 16 would produce 25.50, which no longer describes the confirmed group. The host uses the new denominator for planning but does not rewrite the original payment as a lower amount.

Alternative

Invite additional guests only if the venue and invitation policy allow it. Do not treat more attendance as the only way to justify a room that is already paid for.

Execution notes

Keep estimated attendance and confirmed attendance clearly labelled in notes. BudgetBeacon calculates with the guest count entered; it does not verify RSVPs.
