The incredible amount of money Prince Harry got paid for writing memoir Spare

is said to have received an eye-watering £22million ($27million) from the release of .

Released in hardback on this day in 2023, Spare soon ever after being published by Penguin Random House.

Harry was understood to have clinched a £16million ($20million) advance as part of a £32million ($40million) four-book deal in June 2021, the .

Fellow bestselling author Richard Osman – author of hit crime novels including The Thursday Murder Club – has used his own knowledge of the industry to estimate how much he believes Harry has been paid.

Speaking on his podcast , Osman said: “The book that Harry wrote, it’s impossible to overestimate how much money that has made.

“I mean, it’s been one of the most successful books. The fastest selling non-fiction book of all time.

“I’ve done some back of the envelope calculations because I like to. I know what you get paid per book. Got a $20million advance. Thing with an advance is, you get paid in advance, $20million in that case, you do not make a penny until your publisher makes back their $20million.

“And once they’ve made back their $20million, and there’s all sorts of sliding scales about how that works, what they get, what you get, once you’ve made the $20million, then you get your royalties.”

Ranking up his knowledge, he then added: “I think – and his book has not come out in paperback yet. So this book is purely hardback. I reckon he’s made $26, $27million.

“So he’s earned out an advance of $20million on the hardback of his first book alone. Forget rights to other things and audiobooks and what have you. He has earned that out already. When the paperback comes out, it’s just money rolling into the Sussexes.”

In October 2024, 21 months after its original release, Penguin Random House released the paperback version of Spare.

Although many anticipated new content, the paperback edition contained the same content as the original hardcover edition.
