KDP Paperback Pricing Formula: Printing Costs, Minimums, and Margins

The one formula that governs everything

KDP paperbacks pay: royalty = 60% x list price - printing cost. There are no tiers to choose and no delivery fees - just your price, Amazon's 60%, and the cost to print your specific book. Master the printing-cost table and every pricing question becomes arithmetic.

For black-and-white interiors on the US store, printing costs a flat $2.30 for books under about 110 pages. From 110 pages up, the cost is $0.85 plus $0.012 per page. Color interiors cost substantially more per page, which is why most text books ship with black-and-white interiors and a color cover - covers are always full color at no extra cost.

Printing costs at common lengths

Run the formula at typical lengths: 100 pages costs $2.30 (flat rate). 150 pages: $0.85 + $1.80 = $2.65. 200 pages: $0.85 + $2.40 = $3.25. 300 pages: $0.85 + $3.60 = $4.45. 400 pages: $0.85 + $4.80 = $5.65.

Notice the flat-rate quirk: a 60-page booklet and a 108-page book both cost $2.30 to print, while a 110-page book costs $0.85 + $1.32 = $2.17 - slightly cheaper than a shorter book. If your manuscript lands just under 110 pages, adding a few pages of front matter or workbook space can actually reduce your printing cost.

Your minimum list price

KDP will not let you set a price where the royalty goes negative, so your minimum list price is printing cost divided by 0.60. A 200-page book ($3.25 to print) has a floor of $5.42; a 400-page book ($5.65) has a floor of $9.42. At the minimum you earn exactly zero - it exists to define the range, not to be used.

If you enable Expanded Distribution, the floor rises to printing cost divided by 0.40, since the 40% channel royalty must also cover printing. The 200-page book's floor becomes $8.13. Keep both numbers in mind when you pick a price you intend to keep.

Trim size, by the way, does not change the printing cost for standard black-and-white books - a 6x9 and a 5x8 with the same page count print for the same price. But trim size changes the page count itself: the same manuscript flows into fewer pages at 6x9 than at 5x8, which can nudge printing cost and even push a short book across the 110-page boundary in either direction.

Worked pricing examples

A 150-page nonfiction paperback priced at $9.99: 60% x $9.99 - $2.65 = $3.34 per sale. The same book at $12.99 earns $5.14. Because printing is a fixed cost, each extra dollar of list price adds exactly 60 cents of royalty - so small price increases move margins more than they move buyer behavior in most nonfiction niches.

A 300-page book at $14.99: 60% x $14.99 - $4.45 = $4.54. At $16.99 it earns $5.74. Compare against the visible market: most self-published trade paperbacks sit between $9.99 and $16.99, with longer and more specialized books at the top of that band. Price within the norm for your shelf, then let the formula tell you the margin.

Why the paperback is usually worth publishing

The paperback typically out-earns the ebook per copy - $3-$6 versus $2-$3.50 in the common price bands - and it exists to capture buyers who simply prefer paper, plus it makes your ebook price look small on the same product page. The marginal work is formatting an interior to KDP's trim, margin, and gutter specs and producing a wrap cover with correct spine width. That formatting is exactly what ebookdone generates alongside the ebook for its one-time $9, so the higher-margin format comes free with the manuscript.
