Prince Charles has released some figures as to how much it “costs” to keep Duchess Kate, Prince William and Prince Harry around. I’m going by People Magazine’s report, but I don’t think it matters if these numbers are coming from a pro-royal or anti-royal publication, mostly because Charles’ office didn’t release any specifics, and Harry’s upkeep was lumped in with Will and Kate’s. Even pro-royal people will admit that Harry’s upkeep is probably a very small fraction of what it takes to keep the Cambridges afloat. Plus, these numbers are just what Charles pays towards the maintenance of his children, with no mention of the costs of their security (Will and Kate have a ton of security) or their endless renovations on Kensington Palace Apartment 1 or Anmer Hall.

The palace shed a little light on the cost of running the official life of Prince William and Princess Kate Tuesday – and it’s Prince Charles who largely foots the bill. The staff, travel and official wardrobes for William, Kate and Prince Harry are covered by Charles, who uses a fund totaling $4.6 million.

The future king, 66, pays for his official life by drawing an income from the Duchy of Cornwall, a massive estate given to the heir to the throne to fund his official and private livelihoods. That income in the year to March 31 was $31.1 million, a rise of 1.7 percent, his office at Clarence House says in its annual report out Tuesday.

The budget Charles sets aside for his sons to run their Kensington Palace office, including their official private secretaries and their press team, rose by a modest $60,000, largely accounted for by increased travel – something that has cost more across the board, a palace source suggests.

“We can’t identify how much of it is allocated to their office,” the palace source tells PEOPLE, adding that unlike in previous years, they are not breaking down specific costs, such as Kate’s amazing wardrobe. The $4.6 million also does not account for the costs of refurbishments at William and Kate’s country home, Anmer Hall. The estate was given to the couple by the Queen, 89, and the family pays for the renovations and upkeep privately.

Nor does Charles’s official budget cover the couple’s personal staff – including nanny Maria Turrion Borrallo and new Anmer Hall housekeeper Sadie Rice.

Much of the couple’s major travel, to Australia and New Zealand, was covered by the countries they visited. But William’s week-long tour to Japan and China in February and March cost $109,000 in scheduled flights, and he and Kate’s trip to New York City in December came in at $26,600.

And Prince Harry and his staff paid $135,000 for his flights (both scheduled and charter) to Brazil and Chile last June.

It’s crazy to me that the countries William and Kate travel to have to pick up the costs of the trips. It’s also crazy to me that we can’t even get some breakdowns of “this is what Harry’s upkeep costs” versus “this is what it costs to keep Kate’s closet full of clothes she never wears.” And I think it’s interesting that People notes the difference between official royal staff and the Cambridges’ personal staff. You know Charles is paying for all of those people too – he’s paying for the nannies, the maids, the cooks and everyone else. So let me ask… are the Cambridges worth it? I think Harry is probably worth it – it’s not like he’s working and traveling on a budget, but I also don’t think Harry has crazy-expensive taste in anything other than polo horses. And Harry works constantly and consistently. So, I’ll ask anything: are the Cambridges worth it?
