The Beyoncé bounce - how much is she really worth?

She's already one of the biggest-selling recording artists of all time, the wife of fellow music megastar, mother, multimillionairess, Golden Globe-nominated actress, model, entrepreneur, in the Obama inner sanctum — the rather enviable CV goes almost infinitely on. And now, as if she needed more accolades or influence, Beyoncé is the official face of female empowerment.

Dubbed the “Feminist Live Aid”, tickets for the forthcoming Chime for Change concert at Twickenham Stadium went on sale yesterday. Raising funds for women’s education, healthcare and liberation across the world, the show on June 1 will feature some of Britain’s hottest female talent, including Florence and the Machine and Rita Ora. But the biggest hitter by far — and the one guaranteed to generate pots of gold for the charity — is its headliner, artistic director, and co-founder of Chime for Change, one Beyoncé Giselle Knowles-Carter.

Queen Bey is no longer merely the bootylicious, big-voiced singer with the power-thighs and rump-rocking dance routines, but the most valuable ambassador known to brands. From fashion and beauty to politics and charities, she has her manicured fingers in myriad pies, and anyone wise enough to bring her bounty on board can expect to benefit royally from the Beyoncé bounce.

She’s cashing in quite nicely too, as one half of the most highly paid celebrity couple, with her husband, the rapper Jay-Z, real name, Shawn Carter, — who you can see more of tonight on BBC1, when the film following the singer’s life in recent years, Imagine: Beyoncé — Life Is But A Dream, is shown. Hard to imagine she’s still just 31 years old.

Music

The sales and gongs shout loudly for themselves: the mononymous Beyoncé, who can see off three octaves without breaking a sweat, has sold 118 million solo records worldwide (on top of the 50 million-plus with her former girl band Destiny’s Child), and won 17 Grammy awards (six of them in one record-breaking night in 2010). Her fifth album is due for imminent release, and The Mrs Carter Show, her five-month world tour (including six nights at the O2), kicks off on April 15, during which she is expected to earn about $2 million (£1.3 million) a night.

The girl’s not shy of a lucrative live gig; in 2011 she was the first solo female artist to headline the Pyramid stage at Glastonbury in more than 20 years (fee: undisclosed), just six months after becoming the highest paid performer per minute in the world, when she earned £1.25 million for a five-song performance at a New Year’s Eve party on the Caribbean island of St Barts — that’s £71,040 for every minute behind the mic. And already this year, she’s played arguably the two highest-profile (but unpaid) performances of anyone’s career: President Obama’s inauguration in January and the Super Bowl halftime concert. After the former, she was slammed for miming to a pre-recorded track; she answered her critics a fortnight later with a performance so electrifying — clad in skimpy leather and lace — that she was blamed for blowing the power at the Superdome in New Orleans.

Fashion and Beauty

With her own clothing range, House of Dereon (named after her seamstress grandmother, Agnez Dereon), and walking the runway for Tom Ford, Bey’s been dabbling in fashion for some time. Last week, H&M unveiled her as the new face of its summer collection, out in May. Beyoncé had a hand in the designs, so expect plenty of sequins and bodycon dresses. It’s rather more conservative than the advert for her first perfume, Heat, in 2010. The image of Beyoncé naked was deemed too risqué by British broadcasters and banned from daytime TV but that didn’t stop its success, which sold $100 million (£65 million) in its first year, or that of its two younger perfume siblings, Heat Rush and Pulse.

The Pepsi challenge

Beyoncé is also the new face of megabrand Pepsi, and will even feature on limited-edition cans of the black stuff, as part of a $50-million multi-year endorsement deal. Pepsi will be hoping that her rubber-stamp can boost sales. When in 2006 Bey lost 20lb on the Maple Syrup Diet, sales of the vile detox potion went through the roof.

Marriage and Money

“I truly believe that women should be financially independent from their men,” asserted Beyoncé in that HBO documentary Life Is But A Dream (which she wrote, directed and produced herself). “Money gives men the power to run the show… the power to define value.” Clearly, she’s the right girl to be heading up a gig for female empowerment. Together, the Knowles-Carters are currently the world’s highest-earning celebrity couple, with a combined income of $78 million (£52 million) to May 2012, but Bey just beats Jay, earning $40 million (£26 million) against his $38 million (£24.9 million) last year.

Motherhood

Mrs Carter out-earning her hubby is all the more impressive considering she took time out last year, after giving birth to their daughter, Blue Ivy, now 15 months old. In the three years preceding, she earned an average of $70 million (£46 million) each year. The superstar couple attempted to trademark Blue Ivy as a possible brand name for baby-related products but their efforts were thwarted by Veronica Alexandra, who founded the Boston wedding planning company Blue Ivy back in 2009. The Patent Office ruled that Alexandra could employ the name for events and wedding planning, while Jay-Z and Beyoncé could lend it to potential baby businesses.
