Expected attendance calculator
Use the replies you have. The low and high response rates are your assumptions.
How we worked this out
- The editable low and high percentages show how many unanswered guests might attend.
- Unanswered is invited minus yes and no replies. The high end counts every yes reply.
How the estimate works
The low end discounts yes replies and adds a share of unanswered invites. The high end counts all yes replies and a larger unanswered share.
Chase unanswered guests before making a final order. This range is a planning guess.
Put the plan to work
Create the invitation, collect household replies, and update your plan as answers come in.
