How Much Does It Cost to Self-Publish on Amazon KDP?
The itemized numbers: writing, editing, covers, formatting, and launch ads, plus the royalty math that tells you when a book pays itself back.

Self-publishing on Amazon KDP costs under $1,000 for a self-written nonfiction book: roughly $600 of proofreading, a $150 to $250 cover, and formatting that can be free. Writing it yourself saves the ghostwriter, not the editing bill, and it costs a couple of months of your evenings. Hire a ghostwriter and the full book budget runs $1,200 to $2,000 including cover and formatting. Publishing itself is free, and Amazon takes its cut per sale instead: a $4.99 ebook pays you about $3.43, so a $700 book needs roughly 200 sales to break even.
Those numbers all come from the production and money lessons of our KDP course. The cost side of this business is small and itemizable, which is exactly why the competition is endless. Here is the full bill.
Writing: $0 to $2,000
Three roads, priced in Producing the book.
Write it yourself for free. A useful 30,000-word nonfiction book takes most newcomers a couple of months of regular blocks, so the real cost is time, and the course is blunt that this path also produces the best book when the expertise is yours.
Hire a ghostwriter for roughly $1,200 to $2,000 all-in, the range publishing coaches teach for a full nonfiction book including cover and formatting. Cheaper is possible and more expensive is common. Commission a paid writing test first, one chapter or the introduction, before signing anyone for a whole manuscript. A polished sample on someone else's topic means nothing about their work on yours.
Or assemble it. Low-content books, journals and logs, cost mostly your design time, since you build a clean interior once and produce covers per niche.
Editing: about $600 per manuscript
Skip this and the money you save converts into one-star reviews that never come down. Marketplace rates from Reedsy's 2025 data put proofreading around two cents per word and copyediting about 2.7 cents. A 30,000-word manuscript runs roughly $600 to proofread and about $810 to copyedit. Editing is the one line the course refuses to let you cut.
Cover: $150 to $250
The budget tier for a professional cover that holds up at thumbnail size. This is packaging, not decoration, and packaging is the moat in a business where anyone can produce a book.
Formatting: free to cheap
Word can do a clean basic job for free. Free browser tools cover the same basics, Mac users in this space consistently name Vellum, and freelancers handle it inexpensively. Pay a professional formatter only for image-heavy or complex-table books, and click through every page of KDP's previewer before publishing.
Launch ads: $100 to $300 as tuition
Amazon ads are the one ongoing spend, and Ads on a small budget teaches the starter structure: an auto campaign at a daily budget in the fifteen-to-thirty-dollar range operators teach, bids at twenty to forty cents, plus one manual keyword campaign and one manual product campaign. Leave new campaigns alone for one to two weeks, and let a campaign spend about fifty dollars before judging it.
Treat the first month's budget, $100 to $300, as tuition. It buys data on which keywords convert and whether the book has demand at all. Most of it will not come back.
The payback math
Amazon's cut is per sale, and the royalty table from Royalty arithmetic tells you what each format pays. A $4.99 ebook inside the 70 percent band earns about $3.43 after the delivery fee. A 300-page paperback at $9.99 earns $1.39. A low-content journal at $7.99 earns about $2. Divide your total book cost by your per-sale royalty and you have your break-even in sales. A $700 self-written nonfiction book at $3.43 per ebook sale needs about 200 sales. The trap to check twice: at a $12.99 list price you earn roughly $9.03 per ebook, and at $13.00 about $4.55, because $13 sits outside the 70 percent band.
When the money arrives
Amazon pays monthly, roughly sixty days after the month the royalties were earned. March's sales land near the end of May, so a strong launch month does not rescue your bank balance immediately. Ad spend is real-time while royalties are not, which is why the course defines your year-one ad budget as money you can float for ninety days.
First-year income, per What the money actually looks like, is modest for almost everyone: one documented author sold 11,000 copies and kept about $3,000 after ads and production, and a low-content operator reported about $100 across the first three months before the catalog grew. Budget accordingly, and run this alongside income rather than instead of it. Our runway planning course covers that split.
Every figure here has its source in the free KDP course, with worksheets for the unit economics. If you are comparing this against other businesses you can start for under $1,000, the startup quiz lines them up by budget and timeline.
