By some estimates, Queen Elizabeth’s fortune was close to $500 million in USD. In an age of centibillionaires, it is a modest sum… but Queen Elizabeth’s personal wealth is distinct from that of the monarchy.
Most of the monarchy’s wealth stems from it’s real estate holdings. The Crown Estate, a prominent holding, is estimated to be worth $19 billion USD. By tradition, the Crown Estate is managed by the UK government which gives 25% of the profits back to the monarchy. Last year, that grant was for $99 million USD.
While the monarchy is tax exempt, the personal fortunes of members of the royal family are taxed. But the net worth of the royals remain a secret.
