- Number of ebooks sold (as claimed by the author)
- Number of etitles available (as listed on the author's Kindle page)
- Average sales per title (calculated)
- Primary genre (as estimated by me)
I then put all this data into a nifty Excel spreadsheet and generated some charts and graphs. Which you can see below.
Disclaimers: This data is not complete. I only have data for authors who have publicly claimed 50,000+ sales. There are no doubt more authors who have that many sales but don't publicize it. So, consider this analysis a subset of the actual data. As such, my analysis should be taken with a grain of salt.
*****UPDATED WITH SOME GENRE CORRECTIONS FOR AUTHORS*******
So, get to writing, authors!
As you can see in the chart, of the 78 authors who have sold 50,000 or more ebooks, 71% started their ebook publishing in 2010 or later. Obviously, epublishing opportunities are flourishing.
In case you didn't notice, the table above shows that some of these authors have an average of as low as 1100 sales per ebook. It's just that they ahve so many titles that it all adds up. This should be very heartening to any aspiring authors out there with any books selling 1000 or more copies.
For example, one of my novels, Dead Dwarves Don't Dance, has sold nearly 8000 copies in 17 months (about 5600 a year). I'm looking forward to the day when I have 10 such novels out there. I should be able to sell around 50,000 books a year and make enough to be a full-time novelist!
