Is this the right fit?

In one sentence: The KDP royalty calculator is a free estimator that models Kindle ebook and paperback royalties from price, tax, delivery cost and printing cost.

Best for

  • Best for setting an ebook price before you commit to 35% or 70% in KDP.
  • Best for checking whether a paperback still earns anything after printing cost.
  • Best for pressure-testing margin at 10, 100 or 1,000 sales before you run ads.

Not for

  • Not for Kindle Unlimited forecasting: the page-read payout changes every month.
  • Not a replacement for KDP's own pricing grid, which stays the final word.
  • Not a sales forecast: it estimates payout per copy, not demand.

How it differs

  • Unlike list price times royalty rate, the print estimate subtracts printing cost after the rate is applied, which is where a margin quietly disappears.
  • Ebook vs paperback: ebook economics turn on delivery cost and tax, paperback economics turn on page count, ink and marketplace.
  • Without an estimate before launch, you find out whether a book can carry ads only after you have paid for them.

Interactive estimator

Estimate your KDP royalty

Use this quick model before setting a price. It is an estimate, not a replacement for the official KDP pricing grid.

Verified July 20, 2026. Paperback estimates use black ink, white or cream paper, regular trim size, and KDP's current US, EU and UK costs. Always confirm the final amount inside KDP.

Kindle 35% vs 70%: what changes in the payout?

Estimate 35% or 70% Kindle ebook royalties with tax and delivery cost so pricing decisions are closer to real payout.

  • 35% and 70% royalty options
  • VAT or sales tax estimate
  • Delivery cost for 70% ebook royalty
  • Revenue scenarios by sales volume

Why is a paperback royalty lower than price times rate?

Paperback royalties are easy to overestimate because printing cost is subtracted after the royalty rate is applied.

  • US, EU and UK marketplace examples
  • Black ink regular trim assumptions
  • Automatic 50% or 60% print royalty estimate
  • Minimum price signal for print books

Can this book afford ads, discounts and bundles?

A royalty estimate helps you decide whether a book can support ads, discounts, bundles or a wider catalog strategy.

  • Compare ebook and print economics
  • Estimate profit at 10, 100 or 1,000 sales
  • Spot low-margin print products
  • Pressure-test pricing before launch

FAQ

Is this the official Amazon KDP royalty calculator?

No. It is a practical estimator for planning. Always confirm the final royalty inside KDP's own pricing grid before publishing.

Does the calculator cover Kindle Unlimited page reads?

Kindle Unlimited page-read payout changes monthly, so this page focuses on ebook and print royalty math. Use the related KU guides to model page-read strategy.

Does page count change what I earn on a paperback?

KDP subtracts printing cost from print royalties, so page count, ink type and marketplace can change your margin.
