How this KDP profit calculator works

This tool does not hardcode printing-cost tables because those can change and vary across markets and book setups. Instead, it uses the current royalty formula together with the exact KDP printing cost that you enter.

That makes the output more dependable for real-world decisions. For best results, copy the latest printing cost from KDP, then test different list prices here until the estimated royalty fits your goals.

Frequently asked questions

What formula does the KDP profit calculator use?

Estimated royalty is calculated as list price multiplied by royalty rate, minus printing cost. Standard Amazon sales typically use 60% before print cost, while paperback expanded distribution uses 40%.

Do I need marketplace selection for the profit calculator?

Not for the royalty formula itself. The formula depends on royalty rate and printing cost. Currency selection is mainly for formatting and rounding, while the actual printing cost should come from Amazon KDP for your target marketplace.

Why is minimum list price not fixed?

Minimum list price depends on printing cost, royalty structure, currency step, book type, and KDP rules at the time you publish. That is why this tool shows a formula-based estimate instead of a universal hardcoded minimum.
