Sales Funnel Webinar Conversion Rate Calculator
Estimate key webinar funnel conversion rates from registrations to attendance, offers, sales and revenue.
Overview
This calculator helps you measure webinar funnel performance by turning your registration, attendance, offer-view and sales numbers into simple conversion metrics. Use it to understand where leads drop off and how much revenue your webinar is generating from the traffic you acquire.
How it works
The calculator measures each step of the webinar funnel as a percentage of the previous stage or overall registrations. Attendance rate is attendees divided by registrants, offer-view rate is offer viewers divided by attendees, and buyer conversion rate is buyers divided by offer viewers. Revenue is buyers multiplied by average order value, while ROAS compares gross revenue with ad spend. These figures help you see both conversion efficiency and top-line webinar revenue.

With 1000 registrants, 350 attendees, 200 offer viewers and 30 buyers at an average order value of $497, the webinar generates about $14910 in revenue. That equals a 35.0% attendance rate, a 15.0% offer-to-buyer rate and roughly 7.46x ROAS.
Frequently asked questions
What does this webinar conversion calculator estimate?
It estimates key webinar funnel metrics such as attendance rate, offer-to-buyer conversion rate, registrant-to-buyer conversion rate, revenue and return on ad spend.
What is a good webinar attendance rate?
This varies by audience, reminder sequence and webinar format, but many marketers compare attendance rate as a key benchmark for registration quality and reminder effectiveness.
Why use offer viewers instead of all attendees for sales conversion?
Using offer viewers gives a more realistic close rate because it measures only the people who actually saw the pitch or call to action.
Does gross revenue mean profit?
No. Gross revenue is the total sales value before ad costs, software costs, refunds, taxes and other business expenses.
What if I did not run paid ads?
You can enter 0 for ad spend if your registrations came from email, organic traffic or partnerships. In that case, revenue metrics still work, but ROAS-related figures are less useful.
Can I use this for automated or evergreen webinars?
Yes. As long as you have the total numbers for registrations, attendance, offer viewers and buyers, the same funnel logic applies.
