How much does a wedding after-party cost? A 40-guest example (2026)
For example, a same-night wedding after-party for 40 guests typically costs about $1,490 all-in ($37 per guest), including Extra buffer.
That total is about $150 for the bar / room, $440 for the late-night food, $640 for the hosted drinks, $130 for the bar tip, $0 for the DJ, and $130 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $1,490. This example is a same-night wedding after-party. It is not the wedding reception, and it is not the welcome party.
