There are two business models, and they want different books
Almost every page about this assumes you are selling copies. That is one model, and for most people it is the harder one.
- Selling copies. You publish, a store takes its cut, you keep a royalty on each sale. Scales only with volume, and volume needs an audience or a lot of luck.
- Selling something else. The book is free or nearly free and its job is to bring the right people to a service, a course, a community or a mailing list. One reader who books a call can be worth more than a thousand downloads.
These want genuinely different books. A book built to sell copies has to be worth paying for on its own. A lead magnet has to be worth *giving your email for* and then has to make the next step obvious — which is a shorter, sharper, more specific book than most people write. Choosing before you start is the single cheapest decision on this page.
What one sale actually pays
Amazon pays a 70% royalty inside a price band and 35% outside it, and charges a delivery fee per megabyte on the 70% sales. That combination produces the thing almost nobody sees coming.
| Cover price | Rate | Roughly what you keep |
|---|---|---|
| $2.99 | 70% | $1.79 |
| $4.99 | 70% | $3.19 |
| $9.99 | 70% | $6.69 |
| $12.99 | 35% | $4.55 |
Read the last two rows again. Raising the price from $9.99 to $12.99 cuts what you earn per sale by about a third, because you fall out of the 70% band. Pricing a book at $10.99 because it feels more valuable is one of the most expensive small mistakes in self-publishing.
Work out what your price actually pays, including the band cliff and the delivery fee.
Open the royalty calculatorSelling away from Amazon changes the arithmetic rather than the problem. A distributor like Draft2Digital takes a commission instead of a fee and reaches the stores and libraries Amazon does not. Selling direct — Gumroad, your own site — keeps far more per sale and gets you the customer’s email, which matters more than the extra margin. The trade-offs are here.
The part these pages usually leave out
Most self-published ebooks sell very few copies. Not because they are bad — plenty of good ones sell nothing — but because publishing puts a file in a shop with millions of others and nothing about that act creates demand.
It is worth being concrete about what that means arithmetically. At a $9.99 price you keep a little under $7 a sale, so a hundred sales is roughly a good dinner out and not a month of income. Anybody showing you a screenshot of a five-figure month is showing you the top of a distribution and not telling you the shape of it.
This is not a reason not to publish. It is a reason to decide what the book is *for* before you decide what it costs.
What actually separates the books that earn
Four things, roughly in order of how much they matter, and writing quality is not the first of them.
- 1Somebody was already waiting for it. An audience — a mailing list, a client base, a following, a niche you are known in — is most of the difference. A book written for people who already trust you outsells a better book written for strangers, every time.
- 2It is narrow enough to be findable. "A guide to productivity" competes with everything. "A pricing guide for freelance designers" competes with almost nothing and the people who need it can recognise it in a search result. Narrow does not mean small; it means findable.
- 3It is priced inside the band, on purpose. See the table above. Also: a cheap book is not automatically a better seller — an underpriced non-fiction guide reads as thin, and the 70% floor exists for a reason.
- 4There is more than one. Almost nobody earns from one book. A second book sells the first, a third sells both, and readers who liked one are the cheapest audience anybody will ever have.
The route most people should take first
If you already do something people pay for — coaching, consulting, design, teaching, a service of any kind — selling copies is probably the wrong model for your first book.
A short, specific book given away in exchange for an email does a job royalties cannot: it proves you know the thing, in long form, before anybody has to talk to you. The people who read it and get in touch have already decided. That is why a lead magnet that actually converts is a different piece of writing from a book you would sell — shorter, more specific, and ending somewhere rather than just stopping.
The audience pages go into what this looks like per profession — coaches, consultants and course creators all use books this way, and authors are the ones for whom copies really are the model.
Where BookArc fits, and where it does not
BookArc writes the book. It plans the chapters, writes them, designs a cover and gives you an EPUB and a print-ready PDF — which removes the part that stops most books existing, and none of the part that decides whether they sell.
It does not find you an audience, list your book, set your price or market anything, and no tool that claims to should be believed. What it changes is the cost of trying: writing a second book to see whether a series works is a weekend rather than a season, and that is a genuinely different bet.
You own what it writes outright — no rights taken, no share of what it earns. If you are going to publish it, Amazon requires AI assistance to be declared at upload.
