What percentage of guests RSVP?

For formal events with RSVP cards, 80-90% of guests respond. For casual events with informal RSVPs (text, email), only 50-70% respond. Wedding RSVPs typically get 85-95% response rates. Following up with non-responders significantly improves response rates.

Will guests who did not RSVP still come?

About 40-50% of non-responders typically show up to casual events. For formal events, about 30-40% of non-responders attend. It is always best to follow up directly with anyone who has not responded rather than guessing.

When should the RSVP deadline be?

Set the RSVP deadline 2-3 weeks before the event for casual parties, and 4-6 weeks before for weddings or catered events. This gives you time to chase non-responders and finalise numbers with caterers and venues.

How do I chase RSVPs without being pushy?

Send a friendly reminder 1 week after the RSVP deadline. A personal text or call works better than a group message. Phrase it as needing to confirm numbers for catering rather than chasing them. Most people simply forgot rather than deliberately ignoring the invite.

How We Calculate This

This calculator helps you estimate total attendance by combining confirmed RSVPs with predictions for non-responders.

How it calculates

Response rate = (accepted + declined) / total invited x 100
Acceptance rate = accepted / responded x 100
Estimated from non-replies = non-responders x 45%
Total expected = confirmed yes + estimated from non-replies

The 45% estimate for non-responders is a middle ground. For formal events it may be lower (30-40%), for casual events it may be higher (50%).
