KDP print cost, explained

KDP takes the print cost out of every sale before it pays your royalty. It is set by the interior, the page count, the trim size and the marketplace.

Black ink

On Amazon.com a black-ink paperback up to 108 pages costs a flat $2.30 ($2.84 for a large trim). Above that it is $1.00 plus $0.01 a page ($0.02 for a large trim).

Pages	6 × 9 in	8.5 × 11 in
100	$2.30	$2.84
200	$3.40	$4.40
300	$4.60	$6.10
500	$7.00	$9.50

Color

Premium color: a flat $3.60 up to 40 pages, then $1.00 plus $0.07 a page.
Standard color: $1.00 plus $0.03 a page, from 72 pages.

So a 100-page 8.5 × 11 in color book costs $9.00 in premium color and $5.02 in standard color.

What counts as large

A trim wider than 6.12 in or taller than 9 in is large. 6 × 9 in is regular; 7 × 10 in and 8.5 × 11 in are large.

Hardcover

A black-ink hardcover costs a flat $6.80 up to 108 pages, then $5.65 plus $0.01 a page. A 200-page 6 × 9 in hardcover costs $8.05.
