How to calculate webinar ROI
Webinar ROI compares what a webinar produced with what it cost:
Webinar ROI = (Revenue generated - Total cost) / Total cost x 100
Total cost includes your webinar software, promotion budget, and the time your team spends preparing and hosting. Revenue comes from the deals your attendees go on to close. For a step-by-step walkthrough with examples, read our guide on how to calculate webinar ROI.
If your results look low, check your tracking first. According to the Livestorm 2026 Webinar Benchmark Report, only 6 to 8% of Livestorm customers use a native CRM integration, and 93% of webinar-influenced pipeline never shows up in the CRM.
