How Long Does KDP Review Take?
Amazon KDP review usually takes about 72 hours, though it can vary. Factors like submission volume and the accuracy of your upload affect this. Ensuring your manuscript and metadata comply with KDP guidelines can reduce the waiting period.
Detailed Breakdown of the KDP Review Process
- Initial Submission: After submission, Amazon's system performs an automated check for compliance with guidelines, including file types and basic formatting.
- Manual Review: If the automated checks are passed, your submission enters a queue for manual review. Amazon staff will examine your content for issues like inappropriate content and formatting errors.
- Approval or Rejection: You'll receive a notification of approval or a request for changes. If changes are needed, address these before resubmitting, which can extend the time before your book goes live.
Real-World Example
Consider Jane Doe, who submits a straightforward novel adhering to KDP guidelines. Her review process takes 48 hours. In contrast, John Smith submits a children's picture book with intricate formatting, taking five days due to complexity.
What Affects KDP Publishing Time?
Several factors influence how quickly your book becomes live on Amazon:
- Submission Accuracy: Errors in your manuscript or metadata can lead to rejections, extending your publishing time. Double-check for formatting issues and compliance with KDP guidelines.
- Example: Incorrect ISBNs or author names can delay the process. Ensure all metadata matches the information on your book cover and manuscript.
- Volume of Submissions: During peak times, such as major holidays or events, submission volume can slow down the review process.
- Edge Case: During events like NaNoWriMo, the influx of submissions can lead to longer wait times.
- Complexity of Content: Books with complex formatting or extensive images may take longer to review.
- Example: A cookbook with numerous images and intricate layouts requires more scrutiny than a simple text-based novel.

Understanding KDP Royalties
Royalties on KDP can vary based on factors like your chosen royalty plan (35% or 70%), book price, and distribution options.
Real-World Royalty Calculation Example

- Royalty = (Price - Delivery Cost) * Royalty Rate
- Royalty = ($9.99 - $0.15) * 70% = $6.88 per sale
