How much does a sleepover party cost? A 8-guest example (2026)
For example, a kids’ sleepover for 8 guests typically costs about $180 all-in ($23 per guest), including Extra buffer.
That total is about $0 for the home, $50 for the pizza / dinner, $20 for the movie snacks, $30 for the breakfast, $30 for the crafts / activities, $20 for the decor / lights, $10 for the favors, and $20 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $180. This example is a kids’ sleepover. It is not a kids' venue party, and it is not a daytime birthday.
