KDP Select / Kindle Unlimited
Amazon's exclusive program. 70% royalties in the $2.99–$12.99 range. Inclusion in KU subscription service. Access to promotional tools (Countdown Deals, Free Promotions).
The exclusivity term is 90 days, renewing automatically unless you opt out.
Trade-off: Exclusivity required — no other eBook retailers. Kindle Unlimited pays roughly $0.0044–$0.0049 a page, set monthly rather than fixed, so a fully read 300-page book earns roughly $1.30–$1.50.
Wide Distribution
Reach Apple Books, Kobo, Barnes & Noble, Google Play, libraries. Diversified revenue, reduced platform risk, higher margins on direct sales.
Trade-off: More complex management, no KU revenue, lower individual platform visibility initially.
Direct Sales
90–95% profit margins. Tools: Payhip, BookFunnel, Gumroad, Lemon Squeezy. Requires website, email system, and customer service. Add this layer only once you have an established readership.
The Audio Pillar (Now Mandatory)
In many genres, audiobooks now represent 30–50% of total book revenue. Treating audio as optional leaves significant money on the table.
| Approach | Cost | Quality |
|---|---|---|
| Professional Narrator | $3,000–$15,000 | Highest — best reader satisfaction |
| Self-Narration | $500–$2,000 | High — if you're a good narrator |
| Revenue Share | $0 upfront | High — royalty split with narrator |
| KDP Virtual Voice | Free | Amazon's own synthetic narration, labelled on the listing |
| Third-party AI narration | $100–$500 | Improving — still detectable by some |
