About Webinar Attendance Rate Calculator

Live attendance typically runs at 35 to 50% of registrations, so replays often account for a large share of total reach. Counting both gives a fairer picture of the content's value than live attendance alone.

Formula

Webinar reach

Attendance rate = live attendees / registrations; total reach = live + replay views

Worked example

Frequently Asked Questions

How is live attendance improved?

Reminder sequences, a short registration-to-event window and calendar invitations all lift attendance materially.

Are replay viewers as valuable?

Usually somewhat less engaged, but they can be a large share of pipeline, so they should never be ignored.
