Example Data Table
| Campaign | Registrations | Attendees | Leads | Qualified Leads | Sales | Revenue ($) | Total Cost ($) |
|---|---|---|---|---|---|---|---|
| Growth Webinar A | 1200 | 680 | 180 | 90 | 28 | 14000 | 4200 |
| Product Demo B | 850 | 510 | 132 | 65 | 21 | 10500 | 3100 |
| Partner Event C | 600 | 330 | 88 | 40 | 12 | 5400 | 1900 |
Formula Used
Attendance Rate (%) = (Attendees ÷ Registrations) × 100
Engagement Rate (%) = (Highly Engaged Attendees ÷ Attendees) × 100
Lead Rate from Attendees (%) = (Leads ÷ Attendees) × 100
Lead Rate from Registrations (%) = (Leads ÷ Registrations) × 100
Qualified Lead Rate (%) = (Qualified Leads ÷ Leads) × 100
Sales Rate from Leads (%) = (Sales ÷ Leads) × 100
Sales Rate from Attendees (%) = (Sales ÷ Attendees) × 100
Sales Rate from Registrations (%) = (Sales ÷ Registrations) × 100
Total Cost = Advertising Spend + Other Webinar Costs
Net Profit = Revenue − Total Cost
ROI (%) = (Net Profit ÷ Total Cost) × 100
ROAS = Revenue ÷ Advertising Spend
Cost per Registration = Total Cost ÷ Registrations
Cost per Attendee = Total Cost ÷ Attendees
Cost per Lead = Total Cost ÷ Leads
Cost per Sale = Total Cost ÷ Sales
Revenue per Attendee = Revenue ÷ Attendees

Frequently Asked Questions
1. What is webinar conversion rate?
It measures how effectively webinar participants move through desired funnel stages, such as attending, becoming leads, qualifying, and finally purchasing. The exact percentage depends on which stage pair you compare.
2. Which conversion percentage matters most?
That depends on your goal. Sales teams may focus on lead-to-sale rate, while demand generation teams may prioritize registration-to-attendance or attendee-to-lead performance for earlier funnel improvement.
3. Why track attendance separately from registrations?
Registrations show initial interest, but attendance shows actual audience commitment. A strong registration count with weak attendance often signals reminder, timing, or offer-positioning issues.
4. What counts as an engaged attendee?
An engaged attendee is someone who stayed longer, answered polls, asked questions, clicked offers, or interacted with the presentation. You can define this threshold to fit your campaign goals.
5. What is the difference between ROI and ROAS?
ROI compares profit against total campaign cost. ROAS compares revenue against advertising spend only. Together, they show both marketing efficiency and overall campaign profitability.
6. Can this calculator help with budget planning?
Yes. Cost per registration, attendee, lead, and sale help you estimate future campaign budgets. These values also make it easier to compare webinar channels and promotional strategies.
7. What if a denominator is zero?
The calculator safely returns zero for rates or unit costs when a needed denominator is zero. That prevents division errors and keeps your report readable.
8. How often should webinar conversion be reviewed?
Review it after every webinar and again across monthly or quarterly cohorts. Trend analysis often reveals whether your audience quality, messaging, and offer strength are improving over time.
