What is KDP?

How Kindle Direct Publishing royalties work

KDP pays you a royalty, not a wholesale margin. For Kindle ebooks you generally choose between two royalty tiers, and the higher tier applies only within a defined list-price band and carries a per-megabyte delivery cost deducted from each sale. For print books, Amazon deducts a printing cost (driven by page count and color) from your list price before applying the royalty rate, so a long or color-heavy paperback earns less per copy than a short black-and-white one at the same price.

The practical upshot is that your royalty per sale isn't a single clean number — it varies by format, list price, marketplace, and the delivery or printing cost Amazon subtracts. For bookkeeping you should treat the net royalty Amazon actually deposits as your income, and recognize that the printing and delivery costs are already netted out before you ever see the money.

• •Kindle ebooks: a chosen royalty rate, with a delivery cost deducted on the higher tier
• •Print books: a printing cost (by page count and color) subtracted before royalty
• •Royalty varies by format, list price, and marketplace
• •You're paid net — costs are deducted before the deposit hits your account

KDP Select and exclusivity trade-offs

KDP Select is an optional ebook program that requires you to publish the digital edition exclusively on Amazon for the enrollment term. In exchange your book joins Kindle Unlimited and the lending library, where you earn from pages read rather than copies sold, and you get access to promotional tools like countdown deals and free promotions.

From a revenue standpoint, KDP Select introduces a second income stream — pages-read payouts from a shared monthly fund — alongside ordinary sales royalties. That's worth knowing for your books, because the two streams show up separately and the pages-read rate fluctuates month to month. The exclusivity is the cost: you give up selling the ebook on other platforms while enrolled, which only makes sense if Amazon is where your readers actually are.

Getting paid and the tax side of KDP

KDP pays royalties on a rolling monthly schedule, typically around 60 days after the end of the month in which sales occurred, once you clear a minimum payment threshold for each marketplace. Payments come per-marketplace, so a book selling in the U.S., U.K., and Germany can produce several deposits in different currencies. Setting up your Kindle Direct Publishing account correctly — bank details and the tax interview — is what unlocks those payments.

On taxes, KDP royalties are self-employment income to most U.S. authors, reportable whether or not you receive a year-end form, and Amazon collects tax information through its tax interview during account setup. Because you're paid net of printing and delivery costs across multiple marketplaces and currencies, reconciling KDP income to your bank deposits takes the same discipline as reconciling any Amazon settlement — match the reported royalty to the actual deposit, and book it as income, not as a sale of inventory.

KDP as a sell-on-Amazon-without-inventory model

KDP is one of the few genuinely inventory-free ways to sell on Amazon. There's no purchase order, no landed cost, no FBA storage fee, and no stranded inventory — the product either exists as a digital file or is printed only when ordered. For sellers comparing models, that removes an entire category of cost and risk, at the price of a royalty structure where Amazon takes its printing and delivery cut off the top.

Because there's no COGS in the traditional sense, the accounting is simpler but not trivial: your job is to capture net royalty income accurately across formats and marketplaces and keep it clean for tax time. If you also run a physical-product Amazon business, keeping KDP income clearly separated in your chart of accounts prevents royalty deposits from muddling your product margins.

Frequently asked questions

What is Amazon KDP?

KDP is Kindle Direct Publishing, Amazon's free self-publishing platform for ebooks and print-on-demand books. You upload a manuscript and cover, set a price, and earn a royalty on each sale, with no inventory to buy or store. Print books are manufactured on demand when a customer orders.

How much does KDP pay per book?

There's no single figure — it depends on format, list price, and marketplace. Kindle ebooks pay a chosen royalty rate with a delivery cost deducted on the higher tier, while print books have a printing cost (based on page count and color) subtracted before the royalty is applied. You're always paid net of those costs.

What is KDP Select and is it worth it?

KDP Select is an optional program that makes your ebook exclusive to Amazon for the enrollment term in exchange for Kindle Unlimited inclusion (you earn per page read) and promo tools. It's worth it when Amazon is where most of your readers are; the cost is giving up other ebook platforms while enrolled.

When and how does KDP pay royalties?

KDP pays monthly, generally around 60 days after the month of sale, once you meet a per-marketplace minimum threshold. Payments are issued per marketplace, so international sales can arrive as separate deposits in different currencies. You set up payment and tax details in your KDP account.

How do I account for KDP income?

Treat the net royalty Amazon deposits as income — printing and delivery costs are already deducted, so there's no traditional COGS to book. To most U.S. authors it's self-employment income, reportable regardless of any year-end form. If you also sell physical products, keep KDP royalties in a separate account so they don't distort your product margins.
