Webinar Attendance Calculator
Find how many registrants attend a webinar.
How the Webinar Attendance Calculator works
Webinar Attendance Calculator turns registrants and attendance percent into attendees. It computes that as registrants times the attendance rate.
Worked example: with Registrants 800, Attendance percent 42, this tool returns attendees 336 people, no-shows 464 people. That default state is deterministic, so you can check the page against a known result before trusting your own numbers.
Private, in your browser
Webinar Attendance Calculator runs entirely in your browser with no upload, account, or server call. Every figure is a planning estimate, so confirm anything important against the authoritative source or a professional before you rely on it.
