By accessing or using the KDP Smart Formatter website at kdpformatters.com (“the Website”), you agree to be bound by these Terms of Use. If you do not agree to these terms, please do not use the Website.

KDP Smart Formatter provides free online tools, calculators, and informational guides for authors using Amazon Kindle Direct Publishing (KDP). Our services include royalty calculators, spine width calculators, bleed calculators, gutter calculators, formatting guides, and publishing strategy articles.
All tools and content are provided free of charge with no account registration required. We reserve the right to modify, suspend, or discontinue any tool or service at any time without notice.
All calculations produced by our tools are estimates based on publicly available KDP data. KDP’s actual printing costs, royalty rates, and minimum prices may differ. Always verify critical numbers directly in your KDP dashboard before finalizing your book’s pricing or specifications.
Our calculators use KDP’s published pricing formulas, which can change without notice. While we make every effort to keep our tools accurate and up to date, we make no warranty that tool outputs exactly match what KDP will calculate for your specific book.
We are not responsible for financial decisions you make based on our tool outputs. Always confirm your royalty, minimum price, and printing cost directly in the KDP Publishing platform before publishing your book.
