How eBook royalties work on KDP
Who actually publishes at this length
600-page eBooks are textbook-length: technical references, epic fantasy completed editions, massive non-fiction, and full memoir compilations. Kindle Store > Kindle eBooks > Computing & Internet > Programming Languages and Kindle Store > Kindle eBooks > History both have strong 560 to 660-page Kindle titles.
Pricing dynamics at 600 pages
Stay at $9.99 in the 70% tier - even at 600 pages, the math favors 70% over 35% until the list price exceeds $19. The file size at this length (5 to 7 MB) generates a delivery fee of $0.75 to $1.05, slightly eroding the 70% advantage but not enough to break it.
For Kindle eBooks the math runs differently: at $4.99 in the 70% tier with a 2 MB file you earn roughly $3.28 per sale. At $9.99 (the 70% tier cap) you earn $6.78 per sale. The same book at $10.00 falls to the 35% tier and earns just $3.50. The penny matters.
Real examples in this category
Major fantasy authors' long Kindle editions hold $9.99 to $14.99 (publisher 35%). Technical reference Kindle editions at 600 pages routinely price $24.99 to $34.99 from publishers (35% tier, $8.75 to $12.25 per sale). Indies at this length should sit at $9.99 in the 70% tier.
The common mistake at this page count
Filing a 600-page Kindle eBook at 15 to 20 MB because of unnecessary images, large fonts, or sloppy export. At $0.15/MB the delivery fee can hit $3.00, gutting your royalty. A clean 600-page text-only export should be 5 to 7 MB. Optimize before publishing.
Margin math, in concrete terms
At $9.99 with a 6 MB file ($0.90 delivery fee), royalty is $6.36 per sale (70% of $9.09). Compare to the 35% tier alternative at $14.99: $5.25/sale, $1.11 less per sale, plus you lose the under-$10 price impulse buyers. 70% tier always wins at this length for indies.
Tips for your 600-page eBook
Price $2.99 to $9.99 for 70%
The 70% tier earns 2 to 3x the 35% tier at the same price. Never list at $10.00 when $9.99 earns more.
$4.99 is the sweet spot
Priced low enough for impulse buys, high enough to earn $3.28+ per sale in the 70% tier.
Delivery fee is small
At 2 MB, delivery fee is $0.30. Even at 5 MB it is $0.75. The 70% tier still wins for most books.
