How much does a bachelor party cost? A 8-guest example (2026)
For example, a one-city bachelor night or same-city weekend for 8 guests typically costs about $3,120 all-in ($390 per guest), including Extra buffer.
That total is about $760 for the dinner, $880 for the nightlife, $720 for the activity, $160 for the transport, $160 for the cover charges, $0 for the lodging, $150 for the dinner tip, and $290 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $3,120. This example is a one-city bachelor night or same-city weekend. It is not a destination bachelor week, and it is not the wedding.
