Rates verified against KDP's published tables, July 2026. The 50% and 60% print royalty tiers took effect June 10, 2025. Printing cost is charged on every sale, including Expanded Distribution. Returned books pay no royalty. List prices for the UK, Eurozone and Australia are entered before tax, and Amazon adds VAT or GST on top for the customer. Right at a tier boundary, KDP's own pricing screen is the final word on the minimum.
How KDP royalties work
01
Printing comes out first
Every printed sale pays a fixed charge plus a per-page charge that depends on your marketplace, ink and trim. That printing cost is subtracted from your royalty before anything reaches you.
02
Your price sets the tier
Since June 2025, a print book priced at or above the marketplace threshold earns 60%. Below it, you earn only 50%. The calculator names your tier and shows what the 60% price would earn.
03
eBooks pay 70% or 35%
An eBook priced inside the 70% band earns 70% minus a small delivery fee. Outside the band it drops to 35% with no delivery fee. The band max rose to $12.99 in July 2026.
KDP royalties, answered
How much royalty does Amazon KDP pay per book?
Since June 10, 2025, KDP pays 60% of your list price when the price is at or above a per-marketplace threshold, and only 50% below it. In the US that threshold is $9.99. On a $15.99 paperback that costs $3.40 to print, you earn 60% of $15.99 minus $3.40, which is $6.19. Drop the price to $8.99 and the rate falls to 50%, so you earn $1.10.
How is KDP printing cost calculated?
Printing cost is a fixed charge plus a per-page charge that depends on your marketplace, ink type and trim size. A 200-page US black-ink paperback costs $1.00 fixed plus 200 times $0.012 per page, which is $3.40. Short books fall into a flat tier that charges only the fixed cost, and this printing cost comes out of your royalty on every sale.
Why did my KDP royalty drop below 60%?
On June 10, 2025 KDP changed print royalties so that any paperback or hardcover priced below a marketplace threshold earns 50% instead of 60%. In the US and Eurozone that threshold is $9.99, in the UK it is £7.99, and in Canada and Australia it is $13.99. Most older calculators still show a flat 60%, so they overstate what a low-priced book really earns.
How wide should my book spine be?
Spine width is your page count times a per-page multiplier: 0.002252 inches for white paper, 0.0025 for cream, and 0.002347 for premium color. A 200-page white-paper paperback has a spine of about 0.45 inches, or 11.4 millimetres. KDP only prints text on the spine when a book has 80 pages or more, so thinner books need a blank spine.
Does KDP Expanded Distribution pay less?
Yes. Sales through Expanded Distribution, which reaches bookstores and other retailers, pay a flat 40% royalty rather than the usual 50% or 60%. The printing cost is still charged in full, so the same $15.99 paperback that earns $6.19 on Amazon earns $3.00 through Expanded Distribution. Hardcovers are not eligible for Expanded Distribution.
