In Just Four Months: Princess Charlotte Is Now Worth $5Billion

The youngest member of the royal family, four-month old Princess Charlotte, will be worth nearly $5 billion to the British economy, according to Brand Finance. Her brother? A mere $3.6 billion. 

True, the princess is still trailing her mother Catherine, the Duchess of Cambridge, whose contribution is estimated at $7.2 billion. But given Charlotte has only appeared in public twice -- the day she was born, and during her christening -- the value she's already generating for British business is impressive. 

The "Charlotte effect" brought a huge uplift to fashion and other brands the little princess has worn or been associated with. Her birth generated economic benefits of more than $150 million, Brand Finance estimates. 

"The unofficial endorsement of Charlotte, George and Kate in particular has a profound financial effect running into millions annually," said CEO David Haigh.
