About this calculator

Local guests attend at far higher rates than out-of-town invitees, and destination weddings drop further. This blends attendance rates by group and reconciles them with the RSVPs already returned.

FormulaExpected = Σ(invited by group × attendance rate), blended with returned RSVPs to date.

FAQ

What acceptance rate should I assume?

A typical local wedding lands near 80 to 85 percent. Weekend destination events commonly run 55 to 70 percent, and international travel pushes it lower still.

When should I finalize catering counts?

Most venues want a final number 7 to 14 days out. Once half your RSVPs are returned, the observed rate is usually a better predictor than any model.

Accuracy and limitations

  • Estimates assume standard, average conditions — local rules, pricing, and materials vary.
  • Results are rounded for readability; add a buffer before ordering, booking, or committing.
  • Double-check anything with a real cost attached against a local quote.
