Why Your KDP Payout Never Matches the Headline Rate

Amazon's KDP royalty page quotes two numbers everyone repeats: 70% for Kindle eBooks priced between $2.99 and $9.99, and 60% of list price minus printing cost for paperbacks. Neither number is what actually lands in your bank account once you sell outside the United States. A UK-based author and an India-based author selling the identical eBook at the identical US list price can end up with two different net royalties, and neither one will match the headline 70% figure.

Three separate mechanics create that gap: the delivery cost Amazon subtracts before it calculates your share, the fact that each marketplace runs its own local-currency price band that does not track the live exchange rate, and US withholding tax on royalty income earned by anyone who is not a US taxpayer. A KDP royalty calculator UK sellers can actually rely on has to model all three, not just the 70/35 split. The sections below walk through each deduction with real math, then run a worked example for a UK author and an Indian author selling the same book.

The Three Deductions a US-Only Calculator Skips

Every KDP royalty explainer opens with the same line: 70% inside the price band, 35% outside it. That line describes the gross royalty rate before Amazon subtracts anything. Three deductions apply on top of it, and none of them show up in a simple "price times rate" calculation.

Delivery cost comes first. On the 70% royalty option, Amazon subtracts a per-megabyte delivery fee from your royalty before you get paid, calculated on your book's file size after conversion. A text-only novel barely notices it; an illustrated puzzle book, a picture book, or an image-heavy nonfiction title can lose a meaningful chunk of the royalty to file size alone. Confirm the current per-MB rate for your marketplace on KDP's own pricing and royalty page, since Amazon has adjusted it before and the US figure does not automatically apply everywhere.

Marketplace price bands come second. Amazon does not recalculate the $2.99–$9.99 band from the live GBP or INR exchange rate every time you save a price. Each marketplace has its own fixed local-currency band for the 70% option, set by Amazon and updated only occasionally. Price your UK edition off a converted US figure instead of the published GBP band, and you can land outside the 70% range in the UK store while sitting comfortably inside it in the US store.

US non-resident withholding tax comes third, and it is the deduction most royalty calculators built for US authors never model, because it does not apply to them.

US Withholding Tax: UK 0%, India 15%, and Why That Changes Everything

US withholding tax is the deduction that surprises international authors most, because Amazon's US-facing royalty explainer never has a reason to mention it. Royalties Amazon pays you for sales on amazon.com are US-source income. Under US tax law, a non-US person's US-source royalty income is subject to a default 30% withholding tax, deducted before the royalty reaches your account at all.

You reduce that rate by completing the tax interview inside your KDP account and claiming the benefit of your country's tax treaty with the United States. As of September 2026, the UK-US tax treaty sets the treaty rate on royalty income at 0%, and the India-US tax treaty sets it at 15% under Article 12. Confirm both figures in your own KDP tax interview and in IRS Publication 901 before you rely on them, since treaty schedules are revised from time to time.

Practically, a UK author who completes the interview correctly pays no US withholding at all on Kindle or paperback royalties, while an Indian author pays 15% on top of the delivery cost and price-band effects already covered above. Leave the tax interview blank, or fill it in with the wrong country or entity type, and Amazon defaults to the full 30% rate until you correct it, which is a far bigger hit than either the delivery cost or the price-band mismatch.

This is not tax advice. Whether you need a US taxpayer identification number to claim your treaty rate, and how you report the income at home, depends on your personal situation. Confirm your own requirements with KDP's tax interview guidance or a qualified tax professional in your country, last checked September 2026.

How the 70% Price Band Works in GBP and INR

Amazon publishes a separate 70%-royalty price band for every marketplace it operates, denominated in that marketplace's own currency. The UK band is set in GBP and the India band in INR, and neither one is a live conversion of the $2.99–$9.99 US band. Amazon reviews and adjusts these bands on its own schedule, so a figure you read on an older blog post may already be out of date.

The practical risk is asymmetry. You can set a Kindle price that clears the 70% threshold in the US store, then discover the same book falls just outside the GBP or INR threshold on amazon.co.uk or amazon.in once it is converted, because the local band was never designed to move with the exchange rate. That marketplace pays 35% instead of 70%, quietly, until you notice the gap in your KDP sales dashboard and adjust the local price.

Check the current GBP and INR bands directly on KDP's pricing and royalty page before you set your UK and India list prices, rather than converting the US figure yourself. The same caution applies to paperback minimum list prices, which must clear your printing cost in that marketplace's own currency, not a converted US minimum.

Worked Example: One Book, Two Take-Home Numbers

Priya, a puzzle-book author in Manchester, and Arjun, a puzzle-book author in Pune, each publish the same $4.99 Kindle title with a 3 MB file size, priced inside the 70% band in their respective marketplaces. The figures below use KDP's own published mechanics — the $2.99–$9.99 US-equivalent band, a $0.15-per-MB delivery rate, and the treaty rates named above — applied to that single file. Substitute your own file size, price and current delivery rate from your KDP dashboard for an exact number; the shape of the result holds regardless of the precise inputs.

Neither author sees the advertised 70%. Priya's UK treaty rate means the whole gap comes from delivery cost and any price-band mismatch. Arjun's gap is larger for the identical sale, because the 15% India treaty rate applies on top of the same delivery deduction. Run the same steps against a paperback and the withholding tax still applies, just after Amazon subtracts printing cost instead of a delivery fee.

Paperback Royalties for UK and Indian Sellers

Paperback royalty follows a simpler headline: 60% of your list price minus the printing cost for sales through Amazon's own stores, dropping to 40% of list price minus printing cost if you opt into Expanded Distribution to reach bookstores and other retailers outside Amazon. Amazon has not settled a reduced rate for low-priced US paperbacks as public policy at the time of writing, and sources disagree online about whether one applies — verify the current rate on KDP's own paperback royalty help page before you price a book, since Amazon has changed low-price handling before.

The printing cost itself is calculated in the marketplace's own currency and depends on trim size, page count, and whether the interior is black-and-white or color. Regular trim and large trim, meaning any dimension over 6.12 by 9 inches, use different fee tables, which matters directly for puzzle books, workbooks, and most 8.5-by-11-inch low-content titles. If you are still finalizing interior margins and trim choice, see the guide on KDP interior templates before you run the printing cost numbers.

For UK and Indian authors, the same currency and withholding effects that apply to Kindle royalties apply here too: your GBP or INR list price has to clear the local printing cost plus a real margin, and the resulting royalty is still subject to US withholding tax at your treaty rate before you see it in your account. A UK paperback that nets £3 after printing cost keeps that £3 at a 0% treaty rate; the identical INR-priced edition for an Indian author loses another 15% off the top. If you are weighing Amazon-only paperback sales against wider print distribution, the royalty and cost trade-offs are laid out in the comparison of KDP versus IngramSpark.
