I keep meaning to write a post on how much I spent on my book. I'll crib here, but these numbers are guesstimates.
For a 60k word novel, I spent:
- $100 - Front Cover
- $100 - Back Cover
- $250 - Character Sketches
- $500 - Audio Book Narration
- $250 - Editing
- $75 - Smashwords Formatting
- $300 - CreateSpace (paper edition) Formatting
- $250 - 10 ISBNs
- $35 - Copyright Registration
And... that was pretty much it. Sundry expenses for tools like Scrivener ($50, I think). Most of those things can be avoided entirely. Front Cover and Editing are the only things you cannot do without, imho.
