How do Amazon book royalties work?

What "royalty" means on KDP

A royalty is the amount Amazon pays you for each copy sold, calculated according to KDP’s current rules for that specific format and sale. It is distinct from the list price — the amount a customer pays — because costs and Amazon’s share are factored in before your royalty is determined. Unlike a traditional publishing advance, there is no upfront payment; royalties accrue only as copies actually sell.

Print royalties

For print books, KDP’s current model generally applies a royalty rate to the list price and then subtracts the manufacturing (printing) cost for that specific book before paying you the remainder. Because the printing cost depends on trim size, page count, interior colour and marketplace, the same list price can produce different royalty outcomes for different books.

For example, imagine two paperbacks priced identically, one considerably longer than the other. Once the printing cost — which rises with page count — is subtracted, the shorter book is likely to leave a larger royalty than the longer one at the same price. This is an illustrative example only, not a calculation based on current published figures.

Ebook royalties

Ebook royalties depend on the royalty option you choose when setting up the book, which is generally tied to the list price sitting within a specific band, and in some cases a delivery cost related to file size. Selecting the wrong option for your intended price, or pricing outside a band without realising it, can noticeably change what you earn per sale — so check KDP’s current royalty pages carefully at the pricing stage rather than after publishing.

Printing costs

Printing cost is not something you pay separately — it is subtracted automatically as part of the royalty calculation for each print sale. It scales with page count and can differ for black-and-white versus colour interiors, and can vary between marketplaces because of different print facilities and currencies. Longer or colour books generally carry higher printing costs.

Ebook delivery costs, where relevant

Depending on the royalty option and current KDP rules, a delivery cost based on file size may be subtracted from ebook royalties. This tends to matter more for image-heavy ebooks, such as illustrated non-fiction or children’s books, than for plain text fiction.

List price

The list price you set is the starting point for every royalty calculation. Because thresholds and cost deductions interact with price, changing the list price does not always change your royalty proportionally — it is worth using KDP’s current calculator to check the actual effect of a proposed price change rather than assuming it scales linearly.

Marketplace and currency

A book listed across multiple Amazon marketplaces is priced and paid in each marketplace’s currency (or a converted equivalent), and printing costs for print books can differ by marketplace due to different production facilities. This means your total royalty across marketplaces is a sum of several separate calculations, not one figure multiplied by copies sold.

Taxes

Once Amazon calculates your royalty, tax withholding may apply depending on your country of tax residence and the tax information on file in your KDP account. This is separate from, and applied after, the royalty calculation itself.

Returns and refunds, where relevant

If a customer returns or is refunded for a purchase, the associated royalty is typically reversed in your reporting. This is normal and reflected transparently in your KDP sales dashboard rather than hidden.

Payment and reporting

KDP provides sales and royalty reports inside your account, updated regularly, along with a payment history showing what has been paid and when, based on Amazon’s current payment schedule and thresholds. Reviewing these reports periodically is the most reliable way to understand your actual earnings, rather than relying on estimates.

The author account

All of this — royalty calculations, payment history, tax settings — sits inside the KDP account associated with the book. This is another reason account ownership matters: whoever controls the account sees the reporting and receives the payments.

Why royalties differ between formats

Ultimately, print and ebook royalties differ because print involves a real, variable manufacturing cost that must be recovered before any royalty is paid, while ebooks involve at most a much smaller delivery-related cost. This is not Amazon being inconsistent — it reflects a genuine difference in the underlying economics of producing a physical book versus a digital file.

Common mistakes

• Assuming one royalty rate applies to everything. Format, price band, printing cost and marketplace all affect the actual figure per sale.
• Not checking the royalty option before setting price. Some royalty options are tied to price bands, and pricing outside them changes the calculation.
• Overlooking tax withholding. Incomplete tax information in your KDP account can lead to a larger deduction than necessary.
• Ignoring returns in royalty reporting. Refunded sales reverse the associated royalty, which can look confusing if you are not expecting it.
