kindle royalty calculator

How this Kindle royalty calculator works

If you publish through Kindle Direct Publishing (KDP), your payout is not simply your list price multiplied by units sold. Amazon’s royalty model includes different royalty rates, delivery costs (for certain plans), and optional Kindle Unlimited page-read income. This calculator helps you estimate all three in one place:

• 35% royalty model
• 70% royalty model (when price and market eligibility criteria are met)
• KU/Kindle Unlimited payout using KENP pages read and a per-page payout estimate

KDP royalty formulas (quick reference)

1) Net list price

If your list price includes tax, the calculator first removes tax:

Net price = List price / (1 + tax rate)

2) 35% royalty

Royalty per sale (35%) = Net price × 0.35

3) 70% royalty

Royalty per sale (70%) = (Net price × 0.70) − delivery cost

Delivery cost is estimated as:

Delivery cost = File size (MB) × Delivery fee per MB

4) KU income

KU income = KENP pages read × per-page payout rate

5) Monthly estimate

Total monthly estimate = Sales royalty + KU income

Important assumptions and limitations

• This is an estimator, not an official KDP statement.
• 70% royalty availability depends on marketplace and eligibility rules.
• KENP payout rate changes monthly, so KU estimates can vary.
• Currency conversion, withheld taxes, ad spend, and refunds are not included.
• Printed books (paperback/hardcover) use a different royalty model.

Pricing strategy tips for Kindle authors

Stay in the 70% band when possible

Many authors price between $2.99 and $9.99 to target 70% royalties while keeping prices attractive for readers. If your file size is large (image-heavy books), test how delivery fees change your net earnings.

Use KU as a second income stream

KU can significantly boost income for series fiction and high-read-through catalogs. Even if unit sales fluctuate, page reads can smooth monthly revenue.

Model scenarios before changing price

Try multiple price points in this calculator before launching a promotion. A lower price may increase conversion, but a higher royalty per sale can sometimes yield better total profit even at lower volume.

Example scenario

Suppose your book is priced at $4.99, file size is 2 MB, delivery is $0.15/MB, and you sell 500 copies per month. The calculator compares 35% vs 70% and shows your estimated monthly payout under each. Then it adds KU income from your pages-read estimate. This gives you a realistic earnings range for planning ad spend and launch goals.

Frequently asked questions

Does this include paperback royalties?

No. This page is focused on Kindle ebook royalties and KU page-read income.

Why is my dashboard payout different from this tool?

Your actual payout may differ due to refunds, taxes, country-specific pricing, exchange rates, promotional pricing, or changing KU payout rates.

What KENP rate should I use?

Use a conservative estimate from recent KDP reports or author communities. Many authors test several rates to build a low, medium, and high forecast.
