Ingram allows publishers (I wear both hats) to set the wholesale cut and whether or not to take returns. Bricks and mortar book stores require you take take returns and give them at least a 50% cut. I never wanted to go there so do not take returns and give a 26% cut, 1% over the Amazon minimum.
My print cost is roughly $5.25 and I clear a little over $6 a copy. I also have a kindle e-book edition available directly through Amazon at a list of $9.99 that nets me $6.70 a copy. I sell print copies about 3:1 over the e-book.
Unless the title is a tome, it can be printed as b&w with a print cost in the $4-8 range. Everything after that depends on your competition (for retail price) and your wholesale discount.
At the end of the day I don't see anyone getting rich on any book sales, print or electronic, that are not best sellers from known authors/celebrities. However, as supplemental income you can definitely make some coin with little post authorship effort whether print or e-book.
- set up stripe checkout on the client side only (so you dont have to deal with server logic)
- simply send the book by email when you get a customer
This was my MVP as I didn’t get the time to automate things on the server side. As it’ll get more tedious I’ll find the time to implement that, but so far it’s worked well!
Interestingly, if your editor has an affiliate program you can make as much money by advertising some link that leads to purchases. So as a writer, if you do both you end up getting 20% on these. It’s still not that much.
Recently, I wrote a small handbook about security and the mindset you need to care about security in your company (https://www.securityhandbook.io) and I self published it for 20$ using stripe checkout. Every purchase yields me a bit more than 19$, which feels amazing every time as I directly get the money. I actually made more money selling this self published book than with my big editing company.
