It wasn’t until I answered some e-mails that I realized what other people were having difficulty seeing. The graph in that post is a good one, even though it slopes down toward a leveling off. I’d gotten so wrapped up in reporting day-by-day values (and per-author) values that I never showed the entire total and the shape of that curve.
So, with the brief note that sales have gone exactly as I expected in the just over a week since, let me show you the shape of the overall earnings curve. (This is in USD, by the way.)
The breakdown of contribution by source are the lower curves, the light blue curve is the total revenue (post-fees). The individual author amounts are smaller due to the number of contributors. But this is a novel-length work, and priced accordingly. Where this becomes interesting is that this pretty dramatically shows:
1) That you don’t pay a percentage for day labor. My cost for converting an eBook, while pricey, would already be paid from the revenues from this book.
2) That income comes slowly. Authors are used to an aggregated payment from publishers, not a drib and a drab. That one to two sales a day at Amazon seriously means something over time… and it looks like it’s still continuing to slowly grow on its own.
Good news indeed.
