It takes the details that drive staffing (attendee count, event type, duration, catering style and check-in method) and recommends a headcount for each role. It replaces a rough ratio or a guess with numbers you can explain to clients and vendors.
Industry benchmarks vary by role. Registration typically runs 1 staff per 50–75 attendees for manual check-in, dropping to 1:150 with QR scan. Catering follows 1 server per 8–12 guests for plated dinners, 1:25 for buffet. Security is usually 1 guard per 100–150 attendees for standard events. Venue layout, session count, and event format always affect the final number.
Check-in method is one of the biggest variables in registration staffing. Manual check-in (paper lists, printed badges) requires the most staff. QR code scanning handles 2–3x the throughput per staff member. Self-service kiosks reduce staffing further but need tech support. The calculator accounts for this and flags queue risk automatically if peak wait time is likely to exceed 5 minutes.
The 115% scenario plans for the busiest moments: walk-ins, late additions and everyone arriving for the same session. It isn't a forecast of 15% more people. It's a reserve so your team can absorb a rush without queues or crowding.
A 500-person, single-day conference typically needs 4–6 registration staff (QR scan), 2 AV techs per stage, 1–2 session moderators per track, 2–4 security personnel, and 1 event coordinator per 100 attendees. A buffet lunch for 500 needs roughly 10–14 catering staff. Totals often land between 40–60 people depending on sessions, venue complexity, and how much is outsourced to the venue.
Paid staff are trained and dependable. Volunteers cut labour costs but need more briefing, supervision and backup. Set the paid/volunteer split for each role; most events keep registration, AV and security paid and use volunteers for ushering and wayfinding.
Multi-day events compound several cost drivers: cleaning and logistics staff need higher ratios because venue reset between sessions is more intensive, coordination overhead increases as schedules overlap, and floor staff need shift coverage to stay within working-hour limits. The calculator applies a shift factor for roles requiring continuous floor presence, splitting teams across 8-hour, 9–11-hour, and 12-hour+ event days.
Trade show staffing has unique layers: beyond standard event roles, you need exhibitor support (wayfinding, AV assistance), accreditation staff for badge control at entry, and dedicated cleaning crews between session periods. A 200-booth trade show with 3,000 attendees typically needs 10–15 accreditation staff, 4–6 security, and 6–8 floor coordinators, on top of exhibitor-provided booth staff.
Yes. Outdoor events need more crowd management and security (often 1 usher per 75 attendees instead of 1 per 100 indoors) and more cleaning staff. The calculator adjusts these ratios and alerts you if usher coverage drops too low.
It estimates how much you'd save on registration staff by switching to QR check-in with Eventify. QR check-in usually needs about 20% fewer registration staff. The figure is based on the headcount calculated for your inputs.
The defaults use common industry benchmarks checked against real events. Every venue is different, so each role has a slider to adjust the ratio to your contract, your team or past events. Treat the defaults as a starting point.
Conferences, galas, exhibitions and trade shows, workshops, outdoor events and corporate events. Each type uses different base ratios. A gala with plated service needs very different staffing from a half-day workshop, so pick the closest match first.
Check-in queues (expected wait over 5 minutes), security gaps (more than 150 attendees per guard at 500+ attendee events), crowd management (more than 100 attendees per usher at 1,000+), speaker support (4+ sessions with fewer than 2 liaisons) and cleaning cover.
Finish your inputs, then export. The PDF shows each role's headcount, paid/volunteer split and daily rate, the summary figures and any alerts, so your ops lead, venue or client can sign off on one document.
