Marc Levy (often spelled without an accent on the "e") is undoubtedly one of France's best-known contemporary authors.

His longevity at the top of the rankings and his ability to renew himself ensure Marc Levy a steady stream of income, making him one of France's wealthiest writers.

Although he passed away in 2020, the fortune he accumulated during his lifetime is immense: around 50 million euros at the time of his death. Uderzo, born in 1927, was initially the illustrator of the Asterix adventures, while Goscinny was the scriptwriter.

At 50, this novelist from Antibes has been racking up literary successes for over fifteen years. He has topped the French bestseller list every year since 2011. Musso has built up a huge loyal following with his novels combining suspense and romance (including And then..., The Paper Girl, Central Park, The Girl and the Nightetc.), so much so that it has already sold over 34 million copies of his books sold worldwide.
His commercial influence is such that he benefits from extraordinary contractual conditions: he has been able to negotiate up to 20% in royalties on the sale price of his books, where most writers earn less than 15%. In 2017, an article revealed that Musso had already collected more than 36 million euros in cumulative royalties since his debut - unheard of in France. Each new novel he publishes (usually one a year) sells hundreds of thousands of copies within a few weeks, providing him with a seven-figure annual income.

Several of his novels have been made into films or series (And then... in 2008, the mini-series The Girl and the Night in 2022), and other projects are under development (the rights to Central Park have been acquired for the cinema). These audiovisual adaptations, sometimes negotiated at up to a million euros for a bestseller, further boost his income. Discreet in the media, Guillaume Musso has become France's most bankable novelist in the space of a decade: his name on a cover is a guarantee of massive sales, and in turn, of a financial prosperity unrivalled in the French book industry.

FAQ
Who will be the richest French author in 2025?
In 2025, the richest French author is Guillaume Mussowith an estimated fortune of around 70 million euros. Musso owes this top ranking to his record book sales over the past decade (more than 34 million copies sold) and the highly advantageous publishing contracts negotiated thanks to his status as number 1 author. Behind him are authors such as Albert Uderzo (around 50 million euros, acquired thanks to the Asterix) and Marc Levy (~40 million euros), but Musso is well ahead of them. It should be noted that this ranking may change over time, depending on new literary successes and individual investments, but to date Musso retains a comfortable lead at the top of French writers' fortunes.
How do French authors earn their fortunes?
French authors earn their money through several main channels. Copyright on book sales are the number one source of income. In general, a writer receives between 6% and 12% of the sale price of each book (a rate that can climb to 15% or more for best-selling authors, or even 20% in the exceptional case of Guillaume Musso).
Selling hundreds of thousands or millions of copies brings in substantial revenues. In addition advance payments paid by publishers at the signing of the contract, which can be very high for successful authors (several hundred thousand euros in advance for a potential bestseller, for example).Then there are audiovisual adaptation rights When a novel is made into a film, TV series or play, the author receives a fee for transferring his rights.
In France, the transfer of adaptation rights for a book can be negotiated on average between €50,000 and €100,000; for a much-anticipated bestseller, this figure can rise to €1 million. Authors also earn royalties on derivative products if their universe is adapted (for example, a comic-book author like Uderzo earned royalties on Asterix merchandising). Finally, other sources of income can be added to the mix: collaborations (screenwriting, songwriting), paid speaking engagements, author residencies and so on. However, for the vast majority of writers, it's really the scale of book sales and any successful adaptations that make the difference in terms of fortune.
Which French author has sold the most books?
In terms of the total number of books sold worldwide, Marc Levy is the leading contemporary French author, with over 50 million copies sold. He is closely followed by Guillaume Mussowhich has sold over 34 million copies and is gradually catching up with this figure, thanks to its status as the most widely read author in France every year since 2011.
Other authors in the ranking have impressive sales figures: Bernard Werber has sold some 30 million books worldwide (with particularly strong success abroad), while Albert Uderzo, through the comic strip Asterixhas sold hundreds of millions of albums (even if these were co-created with Goscinny). It should be noted that historically, if we included authors from the past, writers like Jules Verne or Alexandre Dumas would have colossal figures, but for current French authors Marc Levy holds the record in overall volume. C
However, in terms of recent annual sales, Musso has dominated the French market for over a decade - which explains why he is now the richest, even though Levy started earlier and accumulated slightly more sales over time.
Are any French authors billionaires (in euros)?
No, no French author has reached billionaire status in euros. French writers' fortunes are in the millions, not billions. By way of comparison, British author J.K. Rowlingthe creator of Harry Potter, is often cited as the world's first billionaire author, with an estimated fortune of around $1 billion (around 930 million euros).
In France, even the most successful authors such as Guillaume Musso or Marc Levy remain far from these heights, hovering around a few tens of millions of euros. This is partly due to the size of the French-speaking market (smaller than the worldwide English-speaking market dominated by Rowling), and to the fact that very few French authors have been able to diversify their income to the extreme as Rowling has done with spin-off products, theme parks and so on. It's not impossible that one day a French author will achieve a worldwide success comparable to Harry Potter, but to date none of them has made a billionaire's fortune.
Thus, the billion-dollar threshold of euros remains out of reach for our French-speaking novelists, whose wealth, while comfortable, remains an order of magnitude below the greatest Anglo-Saxon literary fortunes.
