Insider Prince William’s finances: Everything the future King loves splurging on

An analysis just took place a few weeks after news of Prince William’s nearly £7million-a-year income tax payments came to light.

The monarch who maintains a lot of secrecy over his finances is known for splurging on occasion and a report by The Daily Mail exposes just what the Prince of Wales gets up to, given he has a private estate called the Duchy of Cornwall that garners him almost £22million-a-year in profit and is worth about £1.1billion.

As for what this goes towards, things like ski holidays, school fees, football tickets, maintenance on seven houses, all falls under the Prince’s monthly costs. However it also includes things like Kate's working wardrobe and costs incurred during royal duties. But those are often written off as tax.

Apart from this he also has received a private inheritance from Princess Diana, as well as Queen Elizabeth II.

The Sunday Times revealed this 7million income tax bill, which places him in the top 0.002 per cent of UK taxpayers. But Royal Author Norman Baker went a bit more in-depth for the outlet and says “in 2024/2025 the Duchy produced a healthy profit of £22.9million. When Charles was Prince of Wales he would every year declare how much tax he had paid, but William discontinued that practice.”

“The recent Sunday Times story, which suggested he paid about £7million in tax last year, perhaps shows that the solid pressure on him to be more open is bearing fruit.”

“We know from an earlier parliamentary inquiry that Charles, when Prince of Wales, claimed expenses against his Duchy of Cornwall income for 28 personal staff - butlers, valets, gardeners and the like - and some expenditure for Camilla before they were even married, including her travel costs, jewellery, and stabling for her horses.”

“Charles in 2009 even tried to get his polo ponies accepted as a business expense,' said Mr Baker, author of Royal Mint, National Debt: The Shocking Truth about the Royals' Finances.”

“We also know that since becoming Prince of Wales, William has refashioned the board of the Duchy of Cornwall, which he insists is a private estate, to bring in investment bankers and property developers, which indicates the generation of profit for himself, rather than wider royal duties, is his top priority.”

He also chalks up some of the private funds to be going towards things like “some maintenance costs for his personal property portfolio of seven houses, clothes and other personal expenses for himself and Kate,” as stated earlier.

However, their yearly trips also add to their expenses like the exclusive French Alpine resort of Courchevel, a place where even a ham and cheese toastie costs €85 (£74), (infused with truffle) according to the Mail.

Other places include things like the decision to rent a private villa in 2019, for two weeks, in the idyllic Caribbean island of Mustique which costs £27,000 a week.

The outlet also exposes some of the prices of their Los Angeles to London flights which costed an estimated $80,000.

Furthermore, Prince George, Princess Charlotte and Prince Louis’ school costs also come out of this. For e.g. the heir is currently studying at Berkshire's prestigious Lambrook School, with fees ranging from £10,669 per term. His siblings also have additional fees of about £9,804.
