The short answer: the median in-person event loses around 20% of its registrants to no-shows. Free events typically see about 28%, paid events about 17%, and live webinars far more, with only a third to a half of registrants attending live. The most effective ways to reduce event no-shows are to create commitment at registration, send well-timed reminders, and give people a clear, personal reason to turn up.
Registrations feel like success, but attendance is what delivers value. Every empty seat is wasted catering, a weaker room atmosphere, and lower sponsor or stakeholder visibility. This chapter sets out realistic benchmarks and the practical steps that close the gap between sign-up and show-up.

What is an event no-show rate?
An event no-show rate is the percentage of registered attendees who do not attend. It is the simplest measure of the gap between interest and commitment.
For example, if 500 people register and 350 attend, the no-show rate is 30%. The inverse, attendees divided by registrations, is the attendance rate (sometimes called the show-up or conversion rate).
Three definitions are the most relevant when comparing figures:
- Registrations should exclude cancellations made before the event, which are a different problem from silent no-shows.
- Attendees for in-person events usually means badge scans or check-ins; for virtual events it means anyone who joined the stream, regardless of how long they stayed.
- Engaged attendance is a stricter measure: people who stayed for a meaningful share of the content. It is the better indicator of whether an event actually worked.
How many registrants actually turn up?
Roughly 60% for webinars, and roughly half for events with a physical element. ON24’s 2026 figures show registration-to-attendance up from 57% the year before. Average attendance per webinar rose 11% to 239, and the last quarter of 2025 averaged 254. Of those who attended, 67% watched live and 43% watched on demand, with some people doing both.
For in-person and mixed events, Bizzabo reports an average attendance rate of 52% across events where attendance was recorded. Its visit-to-registration rate sits at 21.5%, so about one in five people who land on a registration page sign up.
Sector makes a real difference, even on the same platform:
| Sector (ON24, 2026) | Registration to attendance | Average attendees | Average engagement |
| All sectors | 60% | 239 | 49 minutes |
| Life sciences | 65% | 211 | 52 minutes |
| Professional services | Not reported | 260 | 56 minutes |
| Financial services | Not reported | 185 | Not reported |
Plan for a webinar audience of about six in ten registrants, and expect your sector to nudge that up or down.
Three patterns stand out in the data:
- Size matters, up to a point. Small events (10–49 attendees) see a median no-show rate of about 32%. Once events reach 150 or more expected attendees, the rate settles at around 19%.
- Paid events are predictable. Paid events hold steady at roughly 15–18% whatever their size, while free events vary widely.
- Averages hide the worst cases. The mean no-show rate is 29%, well above the median, because 17% of events lose more than half their expected audience.
For virtual events, total reach is higher than live attendance suggests. ON24’s benchmark report puts the average conversion from registration to attendance, including on-demand viewing, at around 60%. This makes on-demand content a valuable safety net for virtual and hybrid formats.
There is little published data on internal corporate events, where attendance is often expected rather than chosen. Our view is that these should be measured on engaged attendance rather than headcount, which we cover below.
Why does the event no-show rate vary so much?
Because commitment varies, and so does the definition of “attended”. A free webinar, a paid conference, an internal town hall and a senior stakeholder summit ask very different things of people. Blend them into one number and you hide more than you show.
Then there’s the counting. “Attended” might mean joining at any point, staying past a set dwell time, scanning a badge at the door, or appearing on a daily register. Each choice moves the rate. It’s a bit like a restaurant that counts walk-ins differently every night and then wonders why its covers look so jumpy.
The report suggests two sensible starting points: a 50% no-show assumption for a free virtual event, and 10 to 15% for a paid in-person one. Treat those as a starting guess, though. The number worth planning against is your own history for that audience, that format and that time of year.
Your own past attendance, measured the same way each time, beats any industry average.
Why do people register and not show up?
Most event no-shows are not a decision made on the day. They are the result of weak commitment at the point of registration, which then erodes as other priorities compete for the same time.
- Low commitment cost. Registering for a free event takes seconds and costs nothing, so it often signals curiosity rather than intent.
- Fading relevance. The gap between registration and event day can be weeks or months. If communications don’t keep the value front of mind, the event slips down the priority list.
- Competing priorities. For senior and corporate audiences especially, a last-minute meeting or deadline will usually win over an event that feels optional.
- Generic experiences. When an agenda looks like it could be for anyone, attendees assume they can catch up later or skip it without missing much.
- Friction on the day. Unclear travel information, a complicated joining link or a long check-in queue can tip a wavering registrant into staying away.
- Registering for the recording. For virtual events, many registrants sign up specifically to receive the on-demand version, with no intention of attending live.
What moves attendance more than promotion?
Registration design. Bizzabo found that dynamic registration flows, forms that change their questions based on earlier answers, converted visitors at 24.4%. Static forms converted at 11.6%. That’s more than double the sign-ups from the same traffic, without spending another pound on media.
Personalisation shows a similar pattern. ON24 reports a 103% increase in attendance where content was personalised. Personalised landing pages converted 45% of visitors against 36% for standard pages.
| Change | Reported effect | Source |
| Dynamic registration form instead of a static one | 24.4% conversion vs 11.6% | Bizzabo |
| Personalised event content | 103% increase in attendance | ON24 |
| Personalised landing page | 45% conversion vs 36% | ON24 |
Why does it work? A delegate who’s been asked what they want, then shown an agenda built around the answer, has made a small commitment before the day. They’ve also been handed a specific reason to show up. Someone who filled in a generic form has neither.
What makes a registration form “dynamic”?
It adapts. Choose “internal comms” as your role and the next question asks about town halls; choose “marketing” and it asks about pipeline. Most event platforms can do this, including Cvent and Bizzabo, and tools like HubSpot forms and Typeform handle branching logic too.
One rule matters more than the tool. Every question should change what the delegate receives next or what you can analyse later. A preference question that changes nothing is worse than no question at all, because it teaches people your form is for show.
Your registration form is the cheapest attendance lever you have, as long as you act on what it tells you.
How to reduce event no-shows
The most effective approach works across the whole attendee journey: attract the right people, build commitment, and remove reasons not to come.
At registration: build commitment
- Charge something, even a little. A modest fee or refundable deposit filters casual sign-ups. Paid events in PheedLoop’s data saw roughly 11 percentage points fewer no-shows than free ones.
- Ask a meaningful question. A short question about goals or interests turns a click into a small act of commitment, and gives you data to personalise the experience.
- Prioritise fit over volume. A smaller list of well-matched registrants will outperform a large list attracted by broad promotion.
- Make it easy to add to a calendar. A calendar invite in the confirmation email secures time in diaries straight away.
Between registration and the event: keep the value visible
- Send a structured reminder sequence. A typical cadence is one week before, one day before and one hour before, each with a fresh reason to attend rather than a repeat of the logistics.
- Reveal content in stages. Announce speakers, sessions and networking opportunities progressively to rebuild anticipation.
- Personalise communications. Tailor messages to what each registrant said they wanted, so the event feels made for them.
- Offer an easy way to cancel or transfer. It sounds counter-intuitive, but letting people release their place gives you accurate numbers and frees seats for a waitlist.
In the final 48 hours: remove friction
- Send clear, practical information. Venue directions, timings, dress code, joining links and what to bring.
- Ask for a final confirmation. A simple “Are you still joining us?” prompt surfaces dropouts in time to fill their places.
- Use SMS or app notifications. These cut through crowded inboxes on the day itself.
Plan for the remaining event no-show gap
Even well-run events will have some no-shows. Plan catering, seating and staffing for realistic attendance rather than registration totals, overbook where your historical data supports it, and offer on-demand access for virtual and hybrid audiences.
The Live Group view: no-shows are a misunderstanding of the audience
Reminder emails and deposits help, but they treat the symptom. People turn up when they believe an event was designed for them and that missing it would cost them something. In an attention economy where every invitation competes with a full inbox and a full diary, generic events lose.
That is why we start with the audience, not the agenda. Understanding who your registrants are, what they want to achieve and what would make the day worthwhile lets you shape content, formats and communications around real people rather than averages. Our AudienceDNA approach uses audience insight to personalise the experience from invitation to follow-up, so registrants see their own priorities reflected at every stage.
We also encourage clients to measure success differently. Headcount tells you who arrived; engaged attendance tells you who stayed, participated and acted afterwards. For internal and stakeholder events, where attendance is often expected, engagement is the more honest measure of whether an event worked.

The median no-show rate for in-person events is around 20%, meaning roughly one in five registrants does not attend. Free events average about 28% and paid events about 17%.
For in-person events, an attendance rate of 80% or more is good, and above 85% is strong. For live webinars, 40–50% live attendance is a solid result.
Free registration requires no financial commitment, so it often reflects interest rather than firm intent. Even a small fee or refundable deposit significantly reduces no-shows.
Three is a common cadence: one week before, one day before and one hour before. Each should give a new reason to attend, not just repeat logistics.
Overbooking works when you have reliable historical data for similar events. Without it, a waitlist is a safer way to fill seats released by cancellations.
Subtract attendees from registrations, divide by registrations and multiply by 100. For example, 500 registrations and 350 attendees gives a 30% no-show rate.
If your events are losing more than one in five registrants, the fix usually starts with understanding your audience better. Talk to Live Group about designing events your audience won’t want to miss.
