Printing costs vary depending on page count and ink type (black ink or color ink). Trim size, bleed settings, and cover finish don't affect printing cost. Printing cost also depends on which Amazon marketplace (website) your paperback was ordered from. Based on the print options you choose, KDP automatically calculates and displays your printing cost in the Rights & Pricing section of title setup.To calculate your paperback's printing cost, we add the applicable fixed cost from the tables linked above to the product of your page count multiplied by the applicable per page cost:
$0.85 (fixed cost) + (300 (page count) * $0.012 (per page Cost)) = $4.45 (printing cost).
