How much does a gala cost? A 150-guest example (2026)
For example, a formal seated fundraiser or awards dinner with tickets for 150 guests typically costs about $32,900 all-in ($219 per guest), including Extra buffer.
That total is about $1,680 for the ballroom, $10,500 for the plated dinner, $5,400 for the bar, $5,100 for the production / AV, $1,800 for the program / entertainment, $1,200 for the auction tech, $1,050 for the centerpieces, $3,180 for the service / gratuity, and $2,990 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $32,900. This example is a formal seated fundraiser or awards dinner with tickets. It is not a casual company holiday party, and it is not a small awards banquet.
