Standard color (lower quality, rare)

Cost = $0.85 + ($0.04 × page count)

Cost by page count (B&W)

PagesPrint CostMin List PricePrice at $4 Royalty
100$2.05$4.56$10.08
150$2.65$5.89$11.08
200$3.25$7.22$12.08
250$3.85$8.56$13.08
300$4.45$9.89$14.08
350$5.05$11.22$15.08

450$6.25$13.89$17.08
500$6.85$15.22$18.08
600$8.05$17.89$20.08

Minimum list price = printing cost ÷ 0.45 (to ensure non-negative royalty on Amazon.com with 60% royalty rate).

Royalty calculation

KDP paperback royalty = (List Price × 0.60) − Print Cost

List PricePrint Cost (300pp)Royalty
$12.99$4.45$3.34
$13.99$4.45$3.94
$14.99$4.45$4.54
$15.99$4.45$5.14
$16.99$4.45$5.74

For expanded distribution (bookstores ordering through Amazon), royalty = (List Price × 0.40) − Print Cost. At $14.99 and 300 pages: ($14.99 × 0.40) − $4.45 = $1.55.

Cost by trim size

Page count depends on trim size. For an 80,000-word novel:

TrimPagesPrint CostBest PriceRoyalty
5” × 8”~340$4.93$14.99$4.06
5.25” × 8”~310$4.57$14.99$4.42
5.5” × 8.5”~280$4.21$14.99$4.78
6” × 9”~235$3.67$13.99$4.72

Larger trims produce fewer pages, lowering print costs. But price expectations also vary by trim — 6×9 books price higher.

Color printing economics

Color interiors are expensive. Think carefully:

PagesB&W CostColor CostDifference
32 (picture book)$1.23$3.09+$1.86
100 (cookbook)$2.05$7.85+$5.80
200 (art book)$3.25$14.85+$11.60
300 (nonfiction)$4.45$21.85+$17.40

A 200-page nonfiction book with color charts: $14.85 print cost. To earn $4 royalty, you’d need to price at $31.42 minimum. Most authors keep interiors B&W and use charts in grayscale.

How formatting choices affect cost

DecisionCost Impact
Font: Garamond vs Palatino~20 pages, ~$0.24/copy
Font size: 11pt vs 12pt~50 pages, ~$0.60/copy
Line spacing: 1.3× vs 1.5×~45 pages, ~$0.54/copy
Trim: 5×8 vs 5.5×8.5~60 pages, ~$0.72/copy
Chapter starts: recto vs next page~15 pages, ~$0.18/copy

Over a 10-book series selling 5,000 copies each, the difference between efficient formatting (Garamond 11pt, 1.35×, 5.5×8.5) and inefficient formatting (Palatino 12pt, 1.5×, 5×8) is roughly $75,000 in printing costs.

Expanded distribution costs

If you enable KDP’s expanded distribution (which puts your book in some wholesaler catalogs):

  • Royalty rate drops from 60% to 40%
  • Same print cost applies
  • Significantly lower per-copy earnings

For serious bookstore distribution, IngramSpark is more effective than KDP expanded distribution.
