Cost per attendee (event CPX)
The fully-loaded cost of an event divided by a chosen outcome — attendees, qualified leads, or meetings. The efficiency metric for experiential and field marketing.
Event CPX is the total cost of an event divided by the outcome you are measuring — cost per attendee, per qualified lead, or per meeting booked. It brings the same per-unit discipline used in media buying to experiential and field marketing.
Why it matters for agencies
Events hide their true cost in venue, travel, staff, and production, so a per-attendee number is the only way to compare them to other channels. Choosing the denominator is everything: cost per attendee flatters a busy booth, while cost per qualified meeting reveals whether the event actually built pipeline.
