Beyoncé was named Forbes' most powerful celebrity of the year in a list unveiled Monday, snatching the top spot from Oprah Winfrey and joining six more African Americans in the top 10 of the magazine's Celebrity 100.

The singer earns an estimated $115m per year, making $2.4m per stop on the massive On the Run tour. Her husband Jay-Z is part of the same tour and also made the top 10, earning an estimated $60m per year.

It was a good year for minorities on the list – seven of the top eight most powerful celebrities, according to Forbes, are black; one, comedian Ellen DeGeneres, is gay. The magazine ranked the celebrities in order of their wealth and influence, measured by media appearances.

The top 10 most powerful celebrities, in order, are: Beyoncé, LeBron James, Dr Dre, Oprah Winfrey, DeGeneres, Jay-Z, Floyd Mayweather, Rihanna, Katy Perry and Robert Downey Jr.

In 2013, six of the top 10 spots were held by women, but only two of the 10 most powerful celebrities were black – Oprah and Beyoncé.

There was more reshuffling elsewhere on the list. Justin Bieber fell to 33 from number nine. Tennis star Roger Federer, director Steven Spielberg and the rock band Bon Jovi dropped out of the top 10 but still made the top 20.

Wildcards included conservative media personality Glenn Beck and Swedish DJ Avicii. Beck's earnings are estimated at $90m per year – he grabbed the number 39 spot. Avicii earned $26m in part on the strength of his single True, the biggest-selling electronic music song ever.
