Webinar ROI FAQ

What is a good webinar attendance rate?

The industry average is 35-45% of registrants attending live. B2B webinars targeting professionals in specialized fields (medical, financial) often achieve 40-55% attendance rates. On-demand views typically add 30-50% more reach post-event.

How do I calculate webinar ROI for pharma?

For pharmaceutical speaker programs and medical education webinars, ROI is typically measured by HCP reach (cost per HCP engaged), downstream prescribing behavior changes (tracked via prescription data), and lead generation for market-access or medical affairs objectives.

What is a good cost per webinar attendee?

Cost per attendee varies widely: simple internal webinars run $10-30 per attendee, externally promoted B2B webinars typically cost $50-150 per attendee, and high-production pharma/medical education events can run $200-500+ per physician attendee due to compliance and production requirements.
