How much does a conference reception cost? A 100-guest example (2026)
For example, an evening reception at a conference for 100 guests typically costs about $13,670 all-in ($137 per guest), including Extra buffer.
That total is about $750 for the ballroom hours, $4,800 for the passed apps / stations, $4,200 for the hosted bar, $400 for the short-program AV, $300 for the branding / signage, $1,980 for the service / gratuity, and $1,240 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $13,670. This example is an evening reception at a conference. It is not a full conference budget, and it is not a seated gala dinner.
