John Mayer has an estimated net worth of $70 million, according to Celebrity Net Worth. In 2018, Mayer earned a spot on the list of Billboard's Highest-Paid Musicians. The year prior, he released his album The Search for Everything, which ended up being the No. 2 album in the Billboard 200. From that album alone, Mayer earned more than $900,000 from album sales and an additional $1 million from streaming.
All of Mayer's successes have awarded him the lifestyle of a superstar. In 2018, Curbed reported that the crooner purchased Adam Levine's one-story pad in Beverly Crest for a cool $13.5 million. The sprawling estate sits on 3.66 acres and includes a 7,100 square foot home, a two-story garage, a swimming pool, and a tennis court.
Mayer has also dropped a lot of coin on his watch collection (per CNBC). He's known as a "watch aficionado," and one of his Patek Philippe watches set him back $300,000. Mayer has not ever publicly disclosed precisely how much his collection is worth, but in 2015, he revealed to The New York Times that it's somewhere in the range of "tens of millions." We can only wonder what piece of real estate or wrist candy Mayer may buy next but one thing's for sure — it will probably be quite expensive.
