The Economics of Book Publishing

How publishers decide which books to publish, how authors are paid, why most books earn little, and how digital formats changed the industry.

Publishing turns an author’s manuscript into a book that reaches readers. The industry has distinctive economics shaped by uncertain demand.

How authors are paid

Advance: an upfront payment from the publisher to the author, often paid in instalments.
Royalties: a percentage of each book’s sales. Authors only receive further royalties once their earned royalties exceed the advance, called “earning out”.

Many books never earn out their advances. Surveys of authors in several countries have found that median earnings from writing are low, and most authors rely on other income.

The publisher’s portfolio

Because it is so hard to predict which books will succeed, publishers operate like investors with a portfolio. They publish many titles, knowing most will earn little while a few bestsellers pay for the rest.

Returns

In many markets, bookshops can return unsold books to publishers for a refund, a system dating back to the Great Depression in the United States. This reduces risk for shops but means publishers must print extra copies and handle returns.

Digital changes

E-books and audiobooks reduced printing and distribution costs. Audiobooks have been one of the fastest-growing segments.
Online retailers, especially Amazon, became dominant sellers, giving them great bargaining power with publishers.
Self-publishing: authors can publish directly as e-books or print-on-demand, keeping a larger share of revenue but taking on marketing themselves.

Accessible books

For blind readers, accessible formats such as braille, audio and accessible digital books are essential. The Marrakesh Treaty allows accessible copies to be made and shared across borders. Many publishers now produce accessible e-books from the start.

The debut novel

A publisher pays a debut author an advance and prints several thousand copies. If the book sells slowly, it never earns out, and the author receives no further royalties. But if it becomes a word-of-mouth hit and sells hundreds of thousands of copies, the author earns substantial royalties, and the publisher's profits help fund future debut authors.

Thinking published authors are usually wealthy

A few bestselling authors earn fortunes, but most published authors earn modest amounts from their books. The industry follows a superstar pattern.

Key takeaways

Authors are paid through advances and royalties; many books never earn out.
Publishers manage risk through a portfolio of titles.
Bookshops can often return unsold books, adding costs for publishers.
E-books, audiobooks, online retailers and self-publishing reshaped the industry.
