KDP Pricing Calculator

Amazon KDP Pricing Calculator for Self-Publishers

Setting the right price for your Amazon KDP paperback is one of the most important decisions you'll make as a self-publisher. Price too low and you'll earn nothing after printing costs. Price too high and readers won't buy. This free KDP pricing calculator helps you find the sweet spot by showing your exact printing cost, Amazon's 40% distribution fee, and your net royalty per sale — all in real time.

The calculator supports all nine Amazon KDP marketplaces worldwide, including the US, UK, Germany, France, Spain, Italy, Japan, Canada, and Australia. It uses the official 2025 KDP printing cost formulas for black & white, standard color, and premium color ink types. You can also see your spine width for both white and cream paper, which is essential for designing your book cover.

Whether you're publishing a novel, a coloring book, an activity book, or a journal, this tool gives you the data you need to make smart pricing decisions. Compare five recommended price points side by side, visualize how your list price is split between you, Amazon, and the printer, and find your minimum viable price instantly.

Frequently Asked Questions

Is this KDP calculator really free?

Yes, 100% free with no limits. Everything runs in your browser — no account needed, no data sent anywhere.

Are the printing costs accurate?

The calculator uses official Amazon KDP 2024/2025 printing cost formulas. Amazon occasionally updates rates, so always verify final costs in your KDP dashboard before publishing.

How is the KDP royalty calculated?

For paperbacks, KDP pays a 60% royalty. Your royalty = (List Price × 0.60) − Printing Cost. If this number is negative, your price is too low.

What is the minimum price?

The minimum price is the lowest list price at which your royalty would be $0.00. It equals Printing Cost ÷ 0.60, rounded up to the nearest cent.

Does trim size affect printing cost?

Trim size does not directly change the per-page rate in the KDP formula, but it affects your page count (larger trims may need fewer pages) and your spine width.

How do I calculate spine width?

For white paper: page count × 0.002252 inches. For cream paper: page count × 0.0025 inches. The calculator shows both values automatically.

Does the calculator work for hardcover?

This version is optimized for KDP paperbacks. Hardcover has a different cost structure that we may add in a future update.
