Realistic expectations
Most people who try this earn around $0–$15 per month in the first year; the high figure of $800 is a ceiling for a focused solo operator, not a typical outcome. The chance of receiving at least one real payout within six months is rated 4/10. Expect the first payment after 30–180 d.
How it works
You take public-domain texts (e.g. from Project Gutenberg), strip the Project Gutenberg name and license, and add original value: a new translation, notes, study guides, audio narration. Readers pay for the added value. KDP requires PD books to be differentiated and pays only 35% royalty on primarily public-domain content (up to 70% for differentiated editions).

AI made translation and annotation cheap, so KDP is flooded with public-domain editions and Amazon tightened AI-content disclosure and daily title limits in 2023-2025. Winners pick under-served languages or niches (classics for learners, bilingual editions) with real scholarly value. Most editions sell a handful of copies.
Pricing strategy
Launch at $0.99-$2.99 to collect reviews, then raise to $4.99+ for annotated or bilingual editions and add paperback.
Path to profit
- Month 0: produce one high-quality annotated or translated edition (cost $0)
- Month 1-3: first sales; expected $5-$20/month
- Month 3-6: publish 3-5 more in the same niche, build a series
- Month 6-12: $20-$100/month from a catalogue of 10+ titles
Business-plan sources:
Payout path
- Methods: KDP EFT/wire, Gumroad/Payhip -> bank
- Minimum payout: KDP: none for EFT
- Frequency: monthly
- Typical delay: 60 days
- Notes: If you keep the Project Gutenberg name/trademark and charge a fee, the PG license requires a 20% royalty on gross profits (due within 60 days of each tax-return date); stripping all PG references and the license avoids this.
Full cycle (setup → earn → bank account)
- Choose PD work
- Add original value
- Strip PG references
- Publish
- Payout to bank
What can be automated
- LLM-assisted translation and annotation
- Automated formatting/EPUB
- Bulk listing
Unavoidable manual steps
- Human editing
- Country PD checks
- KYC
Legality & compliance
Copyright terms vary by country (life+50/70); verify PD status per country.
- Compliance requirements: verify PD status per country; disclose AI-generated content to KDP; tax interview
- Platform availability: KDP pays in most countries.
Risks
- KDP may block undifferentiated PD
- Low sales
Evidence that people get paid
Project Gutenberg's official license (sections 1.C and 1.E.8 and the trademark section) permits free reuse of US public-domain texts once all PG references are removed.
