Invitation-count planner
Work out how many invitations to send to reach your target guest count, based on an expected acceptance rate.
Result
Invitations to send
How to use this tool
- Enter your target number of guests.
- Set an expected acceptance rate — this varies by event type and how well you know your invitees.
- Read how many invitations to send.
Assumptions
- Uses one user-selected attendance rate for every invitee. The 70% prefill is an illustrative scenario, not a measured or universal RSVP rate.
Technical details: what the fields mean
- Target number of guests
targetGuests - The number of guests you're actually aiming to have attend.
- Expected acceptance rate
acceptanceRate - Your expected percentage of invitees who will attend. The 70% default and presets are examples, not event-type benchmarks; use your own RSVP history if available.
Methodology
Invitations to send = target guests ÷ your entered attendance rate, rounded up.
Worked example
Illustrative scenario: 100 target guests, 70% attendance
Inputs: Target number of guests: 100, Expected acceptance rate: 70%
Result: ceil(100 ÷ 0.70) = 143 invitations. Replace the example rate with your own RSVP history or planning assumption.
Practical guidance
- Use attendance data from comparable events you organized, if available. Otherwise, run a few rate scenarios and plan for the range rather than treating one percentage as a forecast.
Common mistakes
- Treating the calculated invitation count as a guaranteed turnout; the rate is a planning assumption and real responses can vary.
FAQs
How many invitations should I send to reach 100 guests?
Enter 100 as the target and use an attendance rate based on your own event history or planning scenario. At the illustrative 70% rate, the estimate is 143 invitations; that rate is not a benchmark or turnout guarantee.

Uses a single flat acceptance rate — real acceptance often varies by how well you know each invitee group.
This tool provides an indicative estimate, based on the assumptions stated above.
