The average American side hustler earns $1,242 (£939) a month, according to a 2026 LendingTree survey of nearly 2,050 consumers. Anne McGraw pulls in up to 16 times that — between $10,000 and $20,000 (£7,560 and £15,120) a month — renting luxury slumber party setups out of a one-car garage in Nashville.

McGraw and her husband both hold full-time corporate jobs. Their side hustle, Firefly Slumber Parties, started in 2020 after their daughter found the concept on social media, according to Side Hustle Nation.
