Use this tool to predict final attendance for your event based on invitation tracking and industry benchmarks. Adjust your response rate expectations to see how they impact your catering and logistics planning.
Estimated Final Headcount:
80
Recommended Catering Buffer (10%):
8 guests
From 100 invitations, your final prediction is 80 guests.
Estimating attendance involves tracking confirmed RSVPs and applying a historical 'show rate' to pending invitations.
Formula: Total Guests = Confirmed Yes + (Pending Invitations × Historical Response Rate)
Total Guests = Confirmed Yes + (Pending Invitations × Historical Response Rate)
Imagine you sent 200 invitations for a Wedding and currently have 120 'Yes' responses with 2 weeks left.
For most events, expect a 10-20% no-show rate among people who RSVP'd 'Yes'.
Set your deadline 2-3 weeks before the event to provide final counts to caterers.
Yes, weddings typically see higher attendance rates (85%) compared to casual office mixers (50-60%).
