King Charles was left the bulk of the late Queen's estate completely tax-free. In 2023, The Guardian carried out what it called the first-ever forensic analysis of the Monarch's private wealth. It uncovered palaces, castles, and estates worth $445 million (£330m) including Sandringham and Balmoral, world-class art, car and stamp collections, opulent jewels, cash courtesy of the Duchy of Lancaster, and much more.

Tallied up, the analysis puts the King's net worth at a staggering $2.4 billion (£1.8bn). That said, The Sunday Times Rich List 2025 estimate is significantly lower at $860 million (£640m).
