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 2025/2026 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.

What is the KDP printing cost formula?

For paperback, the printing cost = Fixed Charge + (Per-Page Cost × Page Count). For US black & white: $0.85 + ($0.012 × pages). For standard color: $0.85 + ($0.07 × pages). Rates vary by marketplace.

How much does Amazon take from each sale?

Amazon takes 40% of the list price as a distribution fee. From the remaining 60%, the printing cost is deducted. What's left is your royalty.

What is a good royalty percentage for KDP?

Most successful self-publishers aim for a royalty of 30-40% of the list price. This typically means pricing your book at 2.5× to 3× the printing cost.

Can I change my book price after publishing?

Yes, you can change your KDP book price at any time through your KDP dashboard. Changes typically take effect within 72 hours.

What is the difference between 35% and 70% ebook royalty?
