Definition

The no-show rate is the percentage of registered attendees who do not actually show up at the event. It is one of the most important metrics in corporate event planning because it directly impacts catering, room, materials and staff sizing.

Details and formula

Formula: (Registered − Attended) / Registered × 100. Example: 500 registered, 410 attended → 18% no-show rate.

Context and typical ranges

Typical ranges by event type:

  • Free events (webinars, open days): 30–50%
  • Paid B2B events: 10–18%
  • Internal corporate events (sales kick-off, training): 3–8%
  • Industry conferences with named badge: 8–15%

How it applies in OAK EVENTS

OAK EVENTS measures no-show in real time during check-in (digital or QR badge), comparing the attendee list with the registration list minute by minute. It also automates T-3 day and T-1 day reminders via email/SMS to reduce no-show by up to 40%.
