More year-end book sales data continues to roll in, with the latest coming from Bookstat. The service collects online sales data in real time from Amazon, Apple, and Barnes & Noble across the print book, e-book, and digital audiobook formats. According to Bookstat, total online sales rose 5.6% in 2022, to $12.13 billion, while unit sales increased 6.6%, to 1.12 billion.

The largest gain in the year was for audiobook sales, which jumped 22% over 2021, to $3.04 billion. For a second year, audiobook sales topped that of e-books, where sales increased 6%, to $2.57 billion. Though sales of print books dipped 0.6%, the format was still the largest by far, with online sales of $6.52 billion.

The most popular format in terms of units was e-books, with unit sales rising 8% in 2022, to 526 million. Unit sales of audiobooks increased 23%, to 188 million units, and print unit sales fell 1.3%, to 403 million.

The discrepancy between the high number of units sold compared to dollar sales of e-books is, of course, price. According to Bookstat, self-published titles, many with prices of $2.99 or lower, accounted for 51% of all unit sales and 34% of revenue in 2022. Based on Bookstat numbers, self-published authors generated approximately $874 million in e-book sales in 2022.

Bookstat estimates that it covers 93% of all U.S. e-book sales, 95% of audiobook sales, and 93% of online print book sales. Bookstat evolved out of founder and CEO Paul Abbassi’s Authors Earnings Report, which began by collecting e-book sales data, eventually adding the capability to track online sales of print titles and digital audiobooks. Abbassi sold the service to Podium Audio last year, and remains head of the company, while Podium has committed more resources to expand and improve the service.
