So I published my 4th novel last week - a rather large work for me (160,000) words.
The ebook pricing was easy - $9.99 all the way. I would have went higher were in not for the 70% bracket.
When we uploaded it to Createspace, the news wasn't good. After Amazon and CS took their cut on the trade paperback size, I would actually have to pay for Extended Distributing copies at a $13.99 price point. The book went 480 pages at a 10.5 font.
We reformatted to indented paragraphs without space and reloaded. It didn't help much, taking about 7 pages out.
We then changed to a 6x9 papersize and down to a 10 point font - that helped a little. Still, I had to go with a $14.95 list price to make decent money.
So here's the trap - The work now lists at 314 pages (actually 340). The paperback isn't selling nearly as well as the ebook, which is abnormal for our books. Normally our paperbacks sell 50% of the copies, but with this work its 10%. Readers can't really tell from Amazon's listing how big the book is because they don't pay any attention to the papersize. It probably looks like Joe is trying to get rich - charging so much for his paperback.
We are going to polish up the marketing - use words like "epic," try to steer reviewers to notice the size, etc...etc...
If I had it to do all over again, I would have fluffed out another 40,000 words and went with two separate books. I'm now making the least amount of money per sale on my longest book. It's just the economics of self-publishing.
I'm not complaining - the book has sold over 1,100 copies in its first week...but over the long run it won't be a good money maker for us.
