As of February 2025, determining Kate Middleton’s net worth is difficult because royal finances are kept private. However, different sources give us an idea of her financial situation.
Celebrity Net Worth estimates Kate Middleton’s personal net worth to be around $10 million. This figure includes her own assets and income, but it does not include the large wealth tied to her royal responsibilities.
As the Princess of Wales, Kate’s financial situation is closely linked to her husband, Prince William. They receive income from the Duchy of Cornwall, a private estate that earns money through land rents and investments. In the fiscal year ending March 2024, the Duchy reported a surplus income of £23.6 million (about $30 million), which helps cover both their official and personal expenses.
In addition to the Duchy of Cornwall, the British royal family owns important assets like the Crown Estate and the Sovereign Grant. These assets are not personally owned by Kate Middleton, but they do contribute to the financial resources available to her and the royal family.
Is Kate Middleton expecting a baby?
While Kate Middleton is not expecting another baby, palace insiders say she sometimes treats Prince William like a “fourth child.”
After rumors about a possible royal pregnancy, a new book has shed light on the relationship between the Prince and Princess of Wales. In Yes Ma’am: The Secret Life of Royal Servants, author Tom Quinn explains that palace staff believe William, 41, can act childish at times.
“Both King Charles and Prince William are prone to tantrums if things are not done to their liking,” a former royal staff member shared with Quinn. “They both get irritated very quickly. They are very picky. It comes naturally to them.”
The book says that Kate, 42, helps balance her husband’s behavior. “I don’t know where William would be without Kate—she hasn’t had everything done for her throughout her life, so she calms him down when he gets a bit fractious,” a source said. “She said he sometimes has to be treated as her fourth child.”
These statements come as Kate is still recovering from her cancer diagnosis, which she publicly shared in early 2024. Despite rumors about a possible pregnancy, the Princess of Wales is focusing on her health and her three children—Prince George, 10, Princess Charlotte, 8, and Prince Louis.
What is Kate Middleton’s Net Worth and is she a famous person?What is Prince William’s net worth?
It’s hard to know exactly what Prince William’s net worth is because the royal family keeps its finances private, but Celebrity Net Worth estimates that his net worth is around $100 million. His great-grandmother, the Queen Mother, who passed away in 2002, put most of her estimated $89 million fortune into a trust fund for her great-grandchildren, William and Harry, in 1994.
“Princes William and Harry will reportedly share about £14m from the estate of their late great grandmother,” the network reported in 2002. That’s about $17.9 million. The bulk of the money was expected to go to the younger brother since William would benefit financially from becoming king.
When William’s grandmother, Queen Elizabeth II, passed away on September 8, 2022, her son, Charles, became King Charles III, and Prince William became the heir to the British throne. This change gave him a large inheritance and several new titles, which added to his property holdings, along with his title as the Duke of Cambridge and Rothesay.
The most significant inheritance was the Duchy of Cornwall, which covers around 130,000 acres in southwest England and was worth about $1.2 billion in 2022. The Duchy of Cornwall was created in 1337 by King Edward III to provide private income to his heir, Edward, later called the Black Prince.
It still serves to support the heir to the throne 685 years later. According to the annual revenue report, the Duchy includes about 2,640 leases and tenancy agreements, 260 farms, $67 million in development land, and around $397 million in commercial property. The official website says the revenue from the estate is used to fund public, private, and charitable activities.
These new properties make William one of the largest private landowners in Britain and will provide him with significant wealth. In 2021, it was estimated that William’s father, Charles (when he was the Duke of Cornwall), managed $23 million in income from the estate, according to the Duchy’s annual accounts.
Alastair Martin, the Secretary and Keeper of the Records for the Duchy of Cornwall, is responsible for expanding the Duchy’s commercial operations. Since 2013, he has increased the Duchy’s assets by 44% by building new properties and benefiting from rising real estate values in the UK.
“I wouldn’t say profit is a dirty word, that’s why we exist,” Martin said about the Duchy in a 2021 conversation with the Royal Agricultural University. Records show that since Martin took over, revenue from commercial activities and the sale of goods has increased by about £5 million ($5.8 million).
The Duchy also added properties like The Oval cricket ground in London, Dartmoor Prison, and the Isles of Scilly to its portfolio. Just last year, Cornwall bought land worth nearly £42 million ($48.5 million), including several housing developments.
