AI tools have collapsed the cost of writing a book, but they haven’t collapsed it to zero. Here’s a realistic line-by-line for taking a 60,000-word nonfiction book from idea to finished, readable, published — in 2026 prices, in plain English. Treat the numbers as ranges, not quotes.
1. Drafting — the AI part ($20–$300)
Most AI writing tools meter usage either as a monthly subscription ($10–$30 for chatbot tiers, $20–$50 for purpose-built writing tools) or by credit consumption. A 60,000-word book typically takes between 250,000 and 500,000 generated words once you count drafts, alternates, edits and rewrites — which lands most projects between $20 and $300 of model spend depending on the tool and the model tier you choose.
Scribbla’s Quill model bills per word with a discount on longer-form personas; a typical full nonfiction draft sits in the lower half of that range.
2. Structural editing ($0–$2,000)
AI can do a credible developmental edit pass — flagging weak chapters, repetitive arguments, structural holes. Free if your tool includes it. If you want a human developmental editor on top, budget $1,000–$2,000 for a nonfiction book of this length.
3. Line editing and copyediting ($300–$1,500)
This is the pass we recommend almost no one skip. AI line-editing is good and getting better, but a human line-editor still catches register, rhythm and the kind of mistakes models systematically reproduce. Freelance rates run roughly $0.01–$0.025 per word.
4. Proofreading ($150–$600)
Final-pass typos, punctuation, consistency. Either a human proofreader or a thorough AI pass plus a careful read-through by a non-author.
5. Cover design ($0–$800)
AI-generated covers are free to a few dollars and can look great with effort. Template-based services run $50–$200. A bespoke designer for a book you want to sell seriously: $400–$800.
6. Formatting and conversion ($0–$200)
Tools like Vellum or Atticus handle EPUB and print PDF for a one-time fee. Writing rooms with built-in publishing (Scribbla’s library is one) skip this line entirely.
7. ISBN and distribution ($0–$295)
Amazon KDP gives you a free ISBN tied to their platform. A U.S. owned ISBN from Bowker is $125 (or $295 for ten). Many countries provide them free.
8. Marketing ($0 – whatever you have)
The bottomless line. The realistic floor: $0 if you already have an audience and use it well. A useful first launch budget: $300–$1,000 for ads, plus a few months of consistent effort. Discoverability inside an existing reader-facing platform (rather than launching cold on Amazon) materially lowers this.
Total ranges
- Lean DIY: $500–$1,500 all-in — AI tools plus a human proof pass.
- Polished indie: $2,000–$5,000 — add line edit, bespoke cover, modest marketing.
- Premium indie: $5,000–$10,000 — full human editorial chain, designer cover, real launch budget.
- Traditional ghostwriting: $25,000–$100,000+, with most of the cost in the writer rather than the production.
Where the math gets interesting
Two costs traditional advice ignores: your time and your reach. A $400 book that takes you three years to ship and sells four copies is more expensive than an $8,000 book that ships in four months and sells four hundred. Most authors over-optimise the visible costs (model spend, cover) and under-optimise the invisible ones (months of stalled progress, no audience to launch into). Pick the workflow that gets your book finished and in front of readers — that’s the only ROI that matters.
