Attendance Rate
Also called: show rate, booking attendance rate
Attendance rate measures whether your booked schedule reflects reality. A class with 12 booked and 10 checked in has an 83% attendance rate. Tracked across the whole schedule, it tells you how much your capacity numbers can be trusted.
Below 75% means your late-cancel and no-show policies aren't working. Members are booking with no real intent to attend, which destroys waitlist value (real demand can't get in because ghost bookings hold the spots). The fix is usually a stricter cancel window plus an actual enforced no-show fee — not just a written policy nobody charges.
Above 92% sometimes flags the opposite problem: you're so capacity-constrained that members only book when they're certain they'll show. That sounds great but it means lost growth — your real demand is higher than your booked schedule reveals. Time to add classes or expand the room.
Track attendance rate by class time, instructor, and member cohort. A specific Tuesday 6:30am class running at 65% attendance with a fully-booked roster is a candidate for a softer time slot. An instructor whose classes consistently run 95%+ is your retention asset.
