How it works

  • Attendees = registrants × show-up rate.
  • Customers = attendees × attendee-to-customer rate.
  • Revenue = customers × average deal value.
  • ROI = (revenue − cost) ÷ cost × 100.

Frequently asked questions

How do you measure webinar ROI?

Add up every cost (ads, tools, the hours your team spent), then track the revenue from customers who attended. ROI is revenue minus cost, divided by cost.

What costs should I include?
