How Amazon KDP Royalties Work

To maximize your author earnings, you must understand the two-tier fee structure of Amazon Kindle Direct Publishing. Amazon typically takes a **40% cut** of the list price as their distribution fee, leaving you with 60% gross.

However, your true profit is the remaining 60% minus the **KDP printing costs**. Printing costs are calculated based on a fixed rate plus a per-page charge, which increases significantly for "Standard Color" or "Premium Color" interiors.

Standard vs. Expanded Distribution

If you opt for **Expanded Distribution**, Amazon's share increases to 60%, meaning you only keep 40% of the list price before printing costs are deducted. Our calculator helps you determine if the increased reach is worth the lower profit margin.
