If I'm reading these figures correctly (I suck at math), then the average Ellora's Cave author in this sample is selling a mere 50 books a year, an Amber Quill author 92. If this sample is representative of erotic ebooks sales as a whole, and that's a big if, the figures are pitiful for authors looking to establish a readership or to make any money. Even so, EREC finds encouragement in these numbers, which they say represent a steady uptick in erotic ebook sales over previous years.
UPDATE: I'm an idiot. When I said I suck at math, I forgot to mention I also suck at reading comprehension. I apologize for my obvious ignorance. Here's an explanation of the first year erotic ebook sales numbers from a reader:
Thank you both for the corrections. I stand corrected (and embarrassed).
That said, the numbers are still pitiful compared to even the worst selling print titles. Erotic ebooks have to go a long, longway before they are competitive with print or make much financial sense for writers (though ebook writers keep insisting that it's the "wave of the future," though the e-tsunami is sure taking it's time getting here from tomorrow). That's assuming, of course, that the writers of erotic ebooks want to make any money, which I suspect isn't as important to them as simply getting their work out there. But even on that level, 1200 people isn't much of an audience. If eyeballs are all those writers care about, they could reach far more people simply by posting their erotic fiction on a blog.
