1. Registration conversion rate

This metric shows you what percentage of your marketing reach converts into actual registrations. 

To calculate it, divide your total registrations by your total marketing reach, then multiply that number by 100. You can also calculate it on a channel-by-channel basis.

For example, say your multi-channel strategy data looks like this:

• Your registration site saw 1,500 organic visitors
• You sent out emails to 5,000 people
• Your LinkedIn Ads campaign reached 3,000 people

That’s a total reach of 10,000 people. If 500 people eventually register, that means your registration conversion rate is 5%. However, if 300 registrations came from one of your LinkedIn ads, that channel has a much higher conversion rate of 10%.

Industry benchmarks vary widely by event type and marketing channel. Email campaigns typically convert at 2-3%, while targeted landing pages might hit 5-10%. Low numbers? Your event proposition, pricing, or targeting might need work. High numbers? Document that marketing mix – it’s working.

2. Attendance rate

Your attendance rate is the percentage of registered attendees who actually show up. The math is straightforward – divide your actual attendees by total registrations and multiply by 100. If 400 people show up out of 500 registrations, that’s an 80% attendance rate. 

In-person events typically see 60-80% attendance, while virtual events often see 40-60%. Workshop rates can vary significantly based on content, audience, and a ton of other factors.

Track this number across all your events and you’ll spot patterns. Weather impacts outdoor events. Monday mornings see more no-shows than Thursday afternoons. Free events have lower attendance rates than paid ones. 

Use these insights to schedule smartly and fine-tune your planning and forecasting.

3. Cost per attendee (CPA)

This metric reveals the price tag of getting each attendee through your door. To calculate, add up everything – venue, catering, staff, marketing, tech, swag – and then divide by your total number of attendees. 

If your event costs $50,000 and draws 200 people, your cost per attendee is $250. There’s no universal “good” number here – a corporate gala might justify $500 per person while a community workshop needs to stay under $50.

Breaking down CPA by expense category reveals your budget-drainers. 

With an event budgeting tool like EventsAir, you can track expenses across key categories like venue, F&B, marketing, and tech., for example. This granular view helps identify where costs are ballooning and where you might find efficiencies for your next event.

4. Net Promoter Score (NPS)

This metric tells you whether your attendees will promote or detract from your future events:

• Promoters (score 9-10): These attendees actively recommend your event
• Passives (score 7-8): These attendees are satisfied but unenthusiastic
• Detractors (score 0-6): Unhappy attendees who might discourage others from attending

Calculate it by asking one simple question after your event: “On a scale of 0-10, how likely are you to recommend this event to a colleague?” Subtract the percentage of Detractors from the percentage of Promoters to get your NPS.

The score ranges from -100 to +100. For events, anything above 0 is positive, +20 is considered good, and +40 or higher is excellent. Track this score over time – it’s your early warning system for attendee satisfaction and a strong predictor of future event success.

5. Revenue per attendee (RPA)

This metric shows you how much money each attendee brings to your event. Calculate it by adding up all revenue sources – ticket sales, sponsorships, merchandise, food and beverage sales, and exhibitor fees – and divide by your total number of attendees.

A conference generating $100,000 with 200 attendees has an RPA of $500. You can compare this against your CPA to understand your profit margin per person, or you can break it down by revenue stream to help answer some really important questions like:

• Is sponsorship revenue underrepresented? 
• Did we sell too many GA tickets?
• We add-ons priced effectively?

While there are lots of ways to track these metrics, event management platforms help make this important data accessible. For example, EventsAir’s financial widgets give you real-time visibility into your revenue streams with dedicated displays for: 

• Profits
• Expenses
• Income

…and more.

When everyone from marketers to finance teams has access to real-time performance data, your team can make smarter decisions about pricing, promotions, and event strategy.

6. Session attendance rate

This metric shows you which parts of your event program are actually drawing crowds. Track attendance for each session, workshop, or breakout and divide by total event attendance. If 160 people attend a keynote out of your 200 total attendees, that’s an 80% session attendance rate.

You can compare these rates across your program to spot patterns in speaker and format preferences.

With EventsAir’s session scanning features, you can capture attendance data using QR codes, beacons, or self-check-in options through the attendee app. This automated tracking shows you exactly how different audience segments engage with your sessions, which makes optimizing your program mix much easier.

7. Sponsor satisfaction score

This metric offers hints about whether your sponsors will come back next year – and how much they’ll spend.

Survey your sponsors post-event using a 1-10 scale across key areas: lead quality, booth traffic, networking opportunities, and overall ROI. Average these scores for each sponsor, then calculate your overall sponsor satisfaction score by averaging all sponsor scores. Track both the overall score and individual component scores.

Wondering how to improve this metric? Here are some common challenges (and solutions):

• Low scores in lead quality? You might need better audience targeting or matchmaking tools. 
• Poor booth traffic? Rethink your floor plan or session scheduling. 
• High overall scores but complaints about networking? Consider using event management platforms like EventsAir that offer dedicated sponsor portals, automated lead capture, and custom meeting matching features to boost sponsor-attendee connections. 

8. Social media engagement rate

If social media is part of your event strategy, this metric reveals your digital footprint and audience reach.

Track total engagements (likes, shares, comments) across platforms, mentions of your event hashtag, and user-generated content during your event. Don’t just count raw numbers, though – measure engagement rate by dividing total engagements by your follower count. 

For example, a post reaching 10,000 people with 500 engagements has a 5% engagement rate. Use this number to track your most valuable channels and your most effective content formats for cost-effective social media marketing.

9. Lead generation rate

This metric helps you demonstrate ROI to your clients and their sponsors – a huge deal when you’re planning B2B events. To calculate it, divide the number of qualified leads by total attendance. If your client’s 500-person trade show generates 100 qualified leads, that’s a 20% lead generation rate. 

You can make this metric much easier to track with event management platforms like EventsAir. We offer automated lead capture technology that lets you focus on event execution while giving clients detailed lead reports and ROI data they can take back to leadership.

10. Event app adoption rate

Last up? Event app adoption. This metric tells you whether your event tech is actually being used.

The idea is pretty simple – a good event app can dramatically improve the experience for planners, attendees, sponsors, and presenters… but only if they actually use it. Calculate the adoption rate by dividing the number of active app users by total registrants and multiplying by 100. 

If 400 out of 500 registrants actively use your app, that’s an 80% adoption rate.

11. Return on Investment (ROI)

Event ROI reveals your event’s financial performance. It shows how much revenue you generated for every dollar spent.

ROI proves your event’s value to stakeholders. A positive ROI means your event generated more revenue than it cost to produce. For example, your event costs $50,000 and generated $75,000 in revenue. Your ROI would be 50%.

This metric justifies event budgets and identifies your most profitable events. Break down ROI by components to understand which investments drive the most value.

12. Attendee Retention Rate

This metric measures how many attendees return to your recurring events, indicating long-term engagement and satisfaction.

For recurring events, track how many attendees from your previous event return for the current one. If 150 out of 300 attendees from last year’s conference return this year, that’s a 50% retention rate.

High retention rates indicate strong event value and attendee satisfaction. Low rates might signal content issues, pricing problems, or competition. Use this metric to identify your most loyal audience segments and understand what keeps them coming back.

13. Check-In Rate

This metric measures how efficiently attendees move through your check-in process and indicates the effectiveness of your registration systems.

Track how many attendees successfully complete the check-in process compared to those who actually arrive at your event. If 380 out of 400 attendees complete check-in, that’s a 95% check-in rate.

A low check-in rate might indicate long lines or confusing processes. It could also signal technical issues with your registration system. High rates suggest smooth operations and a good attendee experience from arrival.

EventsAir’s compatibility with self-check-in kiosks and mobile check-in options helps streamline this process, reducing wait times while providing real-time attendance data.

14. Average Session Rating

This metric reveals the quality and relevance of your event. It captures the attendee’s perspective on your programming. 

Collect ratings for each session on a 1-5 or 1-10 scale. Calculate the average across your entire program. If your 10 sessions receive ratings of 4.2, 4.8, 3.9, 4.5, 4.1, 4.6, 4.3, 4.7, 4.0, and 4.4, your average session rating is 4.35.

This metric identifies your strongest content and speakers, as well as areas needing improvement. Sessions that consistently receive ratings below average may require different speakers, topics, or formats. High-rated sessions can inform your programming strategy for future events.

15. Engagement Score

This metric provides a comprehensive view of how actively attendees participate throughout your event.

Track activities like session attendance, app interactions, networking meetings, Q&A participation, and booth visits. Create a weighted scoring system based on the importance of each action to your event goals.

For example, if your event offers 50 possible engagement touchpoints and the average attendee completes 35, your engagement score is 70%. This holistic metric helps you understand overall event effectiveness beyond individual activities.

EventsAir’s comprehensive analytics automatically track multiple engagement points, from app usage to session participation, giving you complete involvement pictures. 

16. Survey Response Rate

This metric shows how many attendees completed your post-event (or post-session) surveys, which affects the accuracy and actionability of your feedback.

For example, if 600 people attended your event and 150 completed the post-event survey, your response rate is 25%.

The higher the rate, the more confident you can be in your post-event insights. Low response rates may indicate friction in your survey flow or disengaged attendees. 

Pro tip: Send surveys within 24 hours while the event is fresh in attendees’ minds. Keep surveys short (5-7 questions max) and offer incentives for completion.

EventsAir’s survey tools make it easy to collect feedback immediately after sessions or events, boosting your response rates significantly.

17. Booth Traffic Rate

This metric helps measure the success of your exhibit hall or sponsor booths by tracking how many attendees visit each booth relative to total event attendance.

For example, if 1,000 people attend your event and 400 unique attendees visit a sponsor booth, the booth traffic rate is 40%.

High traffic rates mean better exposure for sponsors and exhibitors, increasing the likelihood of ROI for them. This is especially important for trade shows, expos, and B2B events. Low rates might indicate poor booth placement, weak signage, or lackluster booth design.

Use this data to optimize your floor plan and provide sponsors with valuable performance insights. Track traffic patterns to identify prime booth locations for future events.

18. Sponsor ROI

Sponsor ROI measures how well your event delivers value to sponsors, which is crucial for securing repeat sponsorships and building long-term partnerships.

If a sponsor invests $20,000 in your event and gains $60,000 worth of new business, their ROI is 200%. 

Track booth visits, lead scans, branded content views, and post-event sales. This data justifies your sponsorship packages and helps secure renewals.

Share detailed ROI reports with sponsors within 30 days post-event. Include both quantitative metrics and qualitative feedback from their booth interactions. Strong sponsor ROI builds long-term partnerships that reduce your event marketing costs and increase revenue predictability.

19. Content Download Rate

This measures how many attendees downloaded session materials, event guides, or other content provided, indicating interest in your educational or promotional content.

If 300 out of 750 attendees download the event workbook or on-demand session files, your content download rate is 40%. 

High rates show that your content resonates with your attendees. Low rates might mean poor content quality, difficult access, or lack of awareness. Make downloads easy with QR codes, mobile app integration, or email links. Track which content gets downloaded the most to inform future programming decisions.

EventsAir’s content management system lets attendees access materials instantly through your event app, increasing download rates and attendee satisfaction.
