How much it costs to book a band to play a show ultimately depends on the band of interest. Bands that are relatively new and unknown may play for free for the right kind of exposure, while popular acts can cost $100,000 and more to book.
A May 2014 Priceonomics article estimated booking fees for a long list of artists by using data from a third-party booking agency that specializes in college and military shows, and the price range was considerable. For example, stars like Justin Timberlake and Madonna had purported booking fees of more than $1 million, while lesser-known acts cost less than $10,000 to book. Between the two extremes in price, there was a wide middle ground; booking fees for Snoop Dogg ranged from $75,000 to $100,000.
