Prince William’s net worth currently stands at approximately £1.2 billion, far exceeding King Charles III and making him the wealthiest member of the British royal family.
This information was released in the latest financial report of the British royal family on June 25th, along with a report on the Sovereign Grant and the assets of the two principalities of Lancaster and Cornwall. According to the report, the Principality of Cornwall – the asset William inherited upon becoming Prince of Wales after King Charles III ascended the throne in 2022 – is currently valued at approximately £1.2 billion.
In the 2025-2026 financial year alone, William received £21.6 million in personal income from this principality.
This information was released in the latest financial report of the British royal family on June 25th, along with a report on the Sovereign Grant and the assets of the two principalities of Lancaster and Cornwall. According to reports, the Duchy of Cornwall – the estate William inherited upon becoming Prince of Wales after King Charles III ascended the throne in 2022 – is currently valued at approximately £1.2 billion.
In the 2025-2026 financial year alone, William received £21.6 million in personal income from the duchy.
Meanwhile, according to the Sunday Times’ list of the wealthiest people, King Charles III’s personal fortune is currently around £640 million, an increase of £30 million from the previous year, but still significantly lower than the fortune managed by his eldest son.
Notably, for the first time in modern history, King Charles III and Prince William have publicly disclosed their voluntary personal income tax payments.
According to published figures, William paid £7.76 million in income tax and capital gains tax in the 2024-2025 financial year, after having paid £8.34 million the previous year. Since becoming Prince of Wales, he has voluntarily paid over £20 million in taxes.
This move is seen as an effort by the royal family to increase transparency regarding the finances and activities of its senior members.
The report also revealed that William decided to forgo approximately £1.5 million per year in rent from Dartmoor Prison, located in the Duchy of Cornwall. The Devon prison closed in July 2024 after high levels of naturally occurring radon gas were detected, posing a potential risk of lung cancer.
Instead of continuing to receive this revenue, Prince William requested that all funds from the 2026-2027 financial year be channeled into a community rebuilding fund in Princetown to support local residents in overcoming the difficulties following the prison’s closure.
Ian Patrick, the Prince’s private secretary, said William understood that the prison closure had created significant uncertainty regarding employment and the future of the local community. Therefore, he wanted the revenue from the estate to continue to be used to benefit the local people.
Currently, the Duchy of Cornwall spans approximately 51,800 hectares across 19 counties in England and is a major source of income for the heir to the throne. William became the 25th Duke of Cornwall after Queen Elizabeth II’s death in 2022.
In addition, Kensington Palace announced that the number of staff serving Prince William and Princess Kate has increased from 68 to 74. Nearly 15% of the staff belong to ethnic minority groups, while women make up approximately 73% of the workforce.
