KDP Coloring Book Royalty Calculator

Run the numbers for royalties per sale and project monthly income for 15- and 25-book portfolios using conservative, moderate, and optimistic scenarios.

Estimate your royalty per sale

Amazon KDP typically pays 60% of list price, then deducts printing cost per book.
We’ll show all three scenarios by default: Conservative (0.5×), Moderate (1×), Optimistic (3×).
Estimated for standard US black-and-white paperback: reset to estimate.
Default estimate uses $0.85 + ($0.012 × pages). You can replace it if you have your exact KDP estimate.
Formula:
Royalty per sale = (List price × 0.60) − Print cost
Print cost is deducted from your payout by KDP (it’s not a LineForge fee).

FAQ

How does Amazon KDP calculate paperback royalties?

For most paperbacks using the 60% royalty option, KDP pays 60% of list price and then deducts the printing cost per book from your payout.

What print cost does this calculator use?

By default, it uses a standard black-and-white estimate: $0.85 + ($0.012 × pages). You can edit the print cost field if you have your exact KDP estimate for your trim size and marketplace.

Is this only for black-and-white interiors?

Yes. This v1 calculator is designed for typical coloring book interiors (black-and-white). Color printing costs differ and will change the results.

How many books do I need for consistent income?

Many publishers find consistency comes from a portfolio. That’s why this page shows 15- and 25-book projections.

Are these results guaranteed?

No. They’re estimates for planning. Sales depend on niche selection, listing quality, competition, and marketing.
