Prince William net worth: Prince William’s personal net worth is estimated at around $140 million as of 2026, according to Celebrity Net Worth. That figure counts only his personal wealth — not the Duchy of Cornwall, the £1.2 billion estate he controls as Duke but does not own. His annual income from the Duchy was £21.6 million in 2025–26.

Who is Prince William?

Prince William is the heir apparent to the British throne and the elder son of King Charles III and Diana, Princess of Wales. Born on 21 June 1982, he served seven and a half years in the armed forces as a search-and-rescue helicopter pilot, married Catherine Middleton in 2011, and became Prince of Wales and Duke of Cornwall in September 2022. Read his full story in Prince William’s biography.

The key distinction: the Duchy is not his property

Any discussion of Prince William’s wealth has to start with a distinction most headlines get wrong. The Duchy of Cornwall is not his personal property. It is a private estate established in 1337, held in trust for the heir to the throne. As Duke, William is entitled only to the estate’s annual net revenue surplus. He has no access to its capital value, and the proceeds of any capital sales must be retained and reinvested in the estate. When he becomes king, the Duchy passes to his eldest son, Prince George.

That is why reports calling William a “billionaire” are methodologically wrong: they take the Duchy’s £1.2 billion net asset value and present it as his personal net worth. The estate’s value and his personal wealth are two different things, and this article keeps them separate.

The Duchy of Cornwall: £1.2 billion in assets, £21.6 million a year in income

The Duchy’s latest accounts (year ended 31 March 2026) put its net assets at £1.2 billion, covering around 51,800 hectares (about 128,000 acres) across 19 counties in England and Wales. The distributable surplus — William’s private income from the Duchy that year — was £21.6 million.

That income has fallen for two successive years: £23.6 million in 2023–24, then £22.9 million in 2024–25, then £21.6 million in 2025–26. William paid £7.76 million in income and capital gains tax in 2024–25 and £8.34 million in 2023–24 — more than £20 million in total tax since he became Prince of Wales.

Where his personal wealth comes from

Duchy income: £21.6 million in 2025–26 (£23.6m in 2023–24; £22.9m in 2024–25) — his main income, funding his household, staff and charitable work. The Sovereign Grant, £132.1 million in 2025–26, is not his income: it funds the Royal Household’s official duties.
Diana’s inheritance: Diana died in 1997 leaving an estate worth about £21 million gross, £12,966,022 net after inheritance tax, split equally between William and Harry — about £6.5 million each at the time. With investment growth each brother’s share was estimated at around £9–10 million by the time of full receipt at age 30 (William in 2012).
Queen Mother’s trust: the Queen Mother put money into a trust for her great-grandchildren in 1994, reported at around £14 million for William and Harry combined. The split was deliberately unequal — Harry received the larger share, because William would one day benefit from the Duchy. The exact amount William received is not officially confirmed.
Savings and investments: William’s RAF and air-ambulance salaries, together with the growth of his inheritances, make up the remainder of his personal wealth. No public record exists of any personal inheritance from Queen Elizabeth II — her will is sealed — so none is claimed here.

Published estimates: the honest range

No Forbes figure exists for Prince William, and he does not appear on the Sunday Times Rich List. The estimates therefore disagree sharply depending on whether the Duchy is counted:

$140 million — Celebrity Net Worth (November 2026). The only published estimate that separates personal wealth from Duchy capital, noting the Duchy’s net assets of more than $1.3 billion separately. This is the figure used as this article’s headline, cited as an aggregator estimate rather than a verified fact.
About $40 million — Fortune, cited 2022. An estimate of William’s personal wealth before he began receiving Duchy income in September 2022.
About $1.6 billion — Page Six, the Mirror, NDTV, June 2026. Headlines that equate the Duchy of Cornwall’s £1.2 billion net asset value with William’s personal net worth. The underlying Duchy figures are verified; the “billionaire” conclusion is not, because the Duchy is held in trust and William has no access to its capital.

For comparison, his father, King Charles III, is valued at £680 million on the Sunday Times Rich List 2026 (£640 million in 2025) — and the same logic applies there: the Rich List does not count the Duchy of Lancaster or the Crown Estate as the King’s personal assets.

Methodology

The headline figure is the only published estimate that separates William’s personal wealth from the Duchy of Cornwall’s capital value, and it is labelled as an aggregator estimate, not a verified fact. The Duchy’s figures — £1.2 billion net assets, £21.6 million surplus — come from the Duchy’s own published accounts and the House of Commons Library briefing on royal finances. The Diana inheritance figures come from the probate record as reported by the Press Association. Claims that William is a billionaire, that Forbes values him at $1.34 billion, and that the Duchy generates $300 million a year in personal income were all checked and rejected: the first confuses trust assets with personal wealth, the second has no Forbes source behind it, and the third contradicts the Duchy’s audited accounts.
