Her staggering net worth of £3.9 billion is expected to grow as she ages and takes on a more prominent public role.

For those curious, Prince Louis is worth £97.9 million—still a considerable amount, to say the least.

GB News attributes Princess Charlotte’s impressive net worth to the ‘Kate effect,’ citing her striking resemblance to her mother, Kate Middleton, the Princess of Wales.

Brand Finance describes Kate as ‘the most powerful royal fashion influencer.’

They note that clothing and accessories worn by Kate surge in popularity by 38 percent among American fashion buyers.

Whenever Kate is seen sporting a particular outfit, the pieces tend to sell out almost immediately, making many designers eager to dress the Princess.

Besides the ‘Kate effect,’ Charlotte’s massive net worth is also believed to stem from future inheritances and existing investments.

Kate, often coordinating her outfits with Charlotte’s, has set her up as a style icon from a young age.

During Christmas at Sandringham, Charlotte was photographed in a blue and green tartan jacket, while Kate complemented her daughter with a navy suit and a matching tartan scarf.
