Tracking replies as your RSVP deadline approaches? This calculator shows your response rate and outstanding count.
Response Rate = (RSVPs Received / Invitations Sent) x 100
Example
100 invitations sent, 75 RSVPs received:
Response Rate = 75.0% → 25 still outstanding
Why Following Up Directly Is Standard Practice
Following up directly with households that haven't responded as the RSVP deadline approaches is standard wedding planning practice, since a meaningful share of guests simply forget to mail back or submit their RSVP even when they fully intend to attend.
Building in Follow-Up Time Before Final Counts Are Due
Setting your RSVP deadline with at least 1-2 weeks of buffer before your caterer or venue needs a final headcount gives enough time to chase down these outstanding responses without delaying vendor deadlines that are typically non-negotiable.
