Prince Harry Reportedly Set For Multi-Million Dollar Windfall From His Record-Breaking Book 'Spare'

The Duke of Sussex Prince Harry reportedly raked in up to $27 million from his bombshell memoir, "Spare."

According to best-selling author Richard Osman, this amount covers what he has earned for hardcover sales since the book debuted on the shelves in January 2023. He also claimed that Harry will earn more when the paperback goes on sale.

On his podcast "The Rest Is Entertainment," Osman provided insights into the publishing industry, discussing the financial success of Prince Harry's critically acclaimed memoir.

"I've done some back-of-the-envelope calculations because I like to. I know what you get paid per book. [He] got a $20 million advance," the author said about Harry, whose book is "one of the most successful" and "fastest-selling nonfiction books of all time."

Beyond the advance, the writer of "The Thursday Murder Club" claimed that the prince had earned an extra $6 or $7 million based on the sales of the book's hardback alone.

He added that Harry has also earned money for "audiobooks and rights to other things," while the rest of the hardcover sales go to the publishing house to recoup the advance they paid the prince.

Still, according to the book author, the Invictus founder is set to enjoy another financial windfall from the sales of the paperback, which has yet to debut on the shelves.

Currently, there is no release date, as confirmed by the publication through a spokesperson for the publishing house - Penguin Random House.

In his podcast, Osman shut down speculation that the 416-page book wasn't successful because it was sold for a discounted price when it debuted last year.

"Harry is not making less money if it's half-price. He makes exactly the same if you charge $28 and if you charge $14," the crime novelist claimed, per the Daily Mail.

"Also, he sells a lot in America," Osman added, referencing the 1.6 million copies Harry has since sold in the U.S. alone.

Osman continued, "In America, the royalties are absolutely insane because they pay a lot of money for books in America. So he has made a huge amount of money out of that book. So he's got money coming in."

When Prince Harry's "Spare" debuted early last year, it was most talked about for its content, being that it was the first and possibly the only time the former senior royal would embark on such an intimate project.

Unsurprisingly, the bombshell memoir broke several records after its release, becoming the best-selling nonfiction book of all time following its release.

In Harry's home country alone, it sold 400,000 copies in hardback, e-book, and audio on the first day, and a total of over 1.43 million copies in the U.K., U.S., and Canada on that same day.

Within a week of its release, the book had sold over 3.2 million copies globally, setting a record that future memoirs may struggle to surpass. This achievement was particularly even more impressive, considering that the Spanish version of the book was leaked five days before its official release.

In "Spare,"  Harry discussed several intimate details about his life growing up as a royal, his relationship with his family, and their acceptance of his wife Meghan Markle, the Duchess of Sussex.

For the latter, he noted that several senior royals were biased against Meghan, including William, his brother, whom he described as his arch-nemesis.

Eventually, he had a heated argument in 2019 with the heir-apparent, who claimed that Meghan was "difficult," "rude," "abrasive," and had "alienated half the staff."

Harry also claimed that his father did not give him a hug following the death of his mother, Princess Diana, and prevented Meghan from joining the family in Scotland as the late Queen Elizabeth was dying.

The book and Harry and Meghan's Netflix documentary, "Harry & Meghan," has strained his relationship with other senior royals, adding to the tension created by the couple's departure from their senior roles in 2020.

Deadline reported on Thursday that the royal duo currently has two nonfiction series in production.

The first series will focus on Meghan as she talks about the joys of cooking, gardening, entertaining, and friendship. The duchess will executive produce the series alongside Chanel Pysnik for Archewell Productions.

The second series will explore the world of professional polo. It will be shot primarily at the U.S. Open Polo Championship in Wellington, Florida, at The USPA National Polo Center. The series will document the polo world, showing how the players live and compete at the highest level in the game.

Harry's love for polo seemingly inspires the show. He's known as a keen polo player and has even played international games.

The news of the two new Netflix comes after Meghan launched a new business venture called American Riviera Orchard.
