That said, a widely reported study back in 2021 suggested that Charlotte was actually the richest young royal – not to mention the wealthiest child in the world – with a staggering net worth of $4.5 billion (£3.6bn). The same research pegged the fortunes of her brothers, George and Louis, at $3 billion (£2bn) and $127 million (£102m) respectively.

These estimates should be taken with a pinch of salt, however, not least because the study was commissioned by toy company Electric Ride On Cars. The figures are largely speculative and were supposedly based on calculations of potential earnings and future inheritances.
