What’s Really Eating Your Amazon KDP Royalties?

Your book sells at $4.99 and you expect seventy cents per copy. Then the delivery fee hits and you net forty-nine cents instead. Amazon KDP royalties explained sounds simple until you see how pricing, delivery costs, and marketplace choices reshape your actual take-home. The difference between choosing the 35% plan and the 70% plan can double your income or cut it in half.

How the Two Royalty Options Actually Work

Amazon offers two royalty rates: 35% and 70%. You pick one when you publish your book. The 70% option pays more per sale but comes with strict rules. Your book must cost between $2.99 and $9.99 in most markets. You also agree to price matching across all platforms. Amazon can lower your price if they find it cheaper elsewhere.

The 35% option has no price floor or ceiling. You can sell a book for 99 cents or $200. No price matching applies either. You set your price and keep it there. Most authors assume 70% always wins because the number looks better. They’re wrong.

Delivery fees only apply to the 70% royalty option. Amazon charges you for the file size of your ebook. They calculate this at about 15 cents per megabyte in the US. A novel with no images runs about 0.5 MB. That costs roughly seven or eight cents. A cookbook with photos might hit 50 MB. That’s $7.50 per sale deducted from your royalty.

Picture this scenario. You publish a photography book at $9.99 with the 70% option. The file is 80 MB because of high-resolution images. Your gross royalty is $6.99. The delivery fee is $12. You owe Amazon money on every sale. Switch to 35% and you earn $3.50 with no delivery charge.

Amazon KDP Royalties Explained Across Different Marketplaces

Amazon operates separate stores in different countries. Each one pays royalties differently. The US, UK, Canada, and several European markets offer both 35% and 70% options. Other countries only offer 35%. Japan, India, Brazil, and Mexico fall into this second group for most price points.

You earn 35% on sales in countries where 70% isn’t available. This happens even if you selected 70% as your global preference. A reader in India buys your $4.99 book. You get 35% of the local currency equivalent. The system converts this back to your chosen payment currency.

Exchange rates shift constantly. Amazon calculates royalties in the local currency first. Then they convert to dollars or euros or whatever you selected. A weak pound means your UK sales pay less when converted to dollars. You can’t lock in rates or hedge this risk.

Some authors think enrolling in KDP Select changes royalty percentages. It doesn’t. KDP Select gives you access to Kindle Unlimited and the lending library. Readers borrow your book instead of buying it. You earn from a shared fund based on pages read. The fund amount changes monthly. Your standard purchase royalties stay exactly the same.

How Pricing Strategy Changes Your Real Income

Suppose you price a short fiction book at $2.99. You get 70% minus a small delivery fee. Your net is about $2. Drop the price to $0.99 and you fall to 35%. Your net becomes 35 cents. You need six times the sales volume to match the higher price.

Some genres move more copies at lower prices. Romance readers buy in bulk. Dropping from $4.99 to $2.99 might triple your sales. Three times as many sales at similar profit per unit means more total income. Other categories don’t respond the same way. Business book buyers don’t care if the price is $6.99 or $9.99.

Authors often test prices by changing them every few weeks. You start at $4.99 for a month. Then $3.99 for a month. Then $2.99. You compare total royalties across each period. The winner isn’t always obvious. Sometimes the middle price outperforms both extremes.

Promotional pricing temporarily drops your book to 99 cents. This switches you to 35% for the duration. You might run a 99-cent sale for three days to boost visibility. The rank bump can lead to more full-price sales afterward. But those three days pay pennies per copy.

Delivery Fees and File Size Management

Delivery fees eat your royalties on image-heavy books. A children’s book with illustrations might run 20 MB. That’s $3 in delivery costs per sale at 70%. Your $4.99 book nets you about $0.50 after Amazon takes their cut and deducts delivery.

You reduce file size by compressing images before upload. Export images at 72 DPI instead of 300 DPI. Use JPEG instead of PNG for photos. Convert color images to grayscale if the content allows it. These changes can shrink a file from 40 MB to 8 MB.

Some authors split large books into volumes. A massive cookbook becomes Volume 1 and Volume 2. Each volume has half the images. Each file is smaller. Delivery fees drop. You sell two books instead of one. Total revenue often increases even though readers pay twice.

Text-only books rarely trigger significant delivery fees. A 400-page novel with no images usually sits under 1 MB. The delivery cost rounds to pennies. You ignore it. Fiction writers almost never need to worry about this. Nonfiction authors with screenshots and diagrams face the opposite problem.

Returns, Refunds, and Royalty Clawbacks

Amazon lets readers return ebooks within seven days. You get paid when someone buys your book. Amazon claws back the royalty when they return it. Your monthly statement shows both sales and returns. Net royalties equal sales minus returns.

Return rates vary by genre and book quality. A well-edited book with an accurate description sees few returns. A misleading cover or poor formatting triggers more. Some months you might see 5% of sales refunded. Other months it’s 15%. The pattern tells you if something is wrong.

Kindle Unlimited borrows don’t generate returns the same way. A reader borrows your book and reads ten pages. You earn for those ten pages. They never finish the book. You keep the payment. No clawback happens. Borrows behave differently than purchases in this respect.

Serial refunders abuse the system. Someone downloads your book, reads it fully, then returns it before seven days. Amazon pays attention to this behavior. They ban accounts doing it repeatedly. But you still lose the royalty on individual returns. Nothing you can do stops a single return.

Tax Withholding and Payment Thresholds

Amazon withholds tax on your royalties depending on your country. US authors complete a W-9 form. No withholding applies. Non-US authors file a W-8BEN to claim treaty benefits. Without it, Amazon withholds 30% of your US sales. The money goes to the IRS.

Tax treaties reduce withholding to 0% or 10% for many countries. A UK author files the W-8BEN and claims treaty benefits. Amazon withholds nothing on US sales. An author in a country without a treaty loses 30% automatically. You never see that money.

Amazon pays royalties about 60 days after the end of each month. Sales from January arrive in late March. You need to reach a minimum threshold before they send payment. The threshold is $100 for direct deposit in the US. It’s higher for other methods and countries.

Your royalties sit in your account until you hit the threshold. Suppose you earn $60 in January and $50 in February. You get paid in late April for both months combined. Low-volume authors might wait several months between payments. The money accumulates until it crosses the line.

Expanded Distribution and Its Royalty Impact

Expanded distribution sends your ebook to libraries and third-party retailers through Amazon. You enable it with a checkbox during publishing. It pays 35% royalty regardless of your main KDP choice. You enrolled in 70% for direct Amazon sales. Expanded distribution still pays 35%.

Sales through this channel appear separately on your dashboard. You see which copies sold on Amazon directly and which went through other outlets. The volume is usually small. Most authors report under 5% of total sales coming from expanded distribution. But it’s passive income with no extra work.

You can’t use expanded distribution if you’re in KDP Select. Select requires exclusivity to Amazon. You choose between Select benefits and expanded reach. Most authors pick Select for the Kindle Unlimited income. The page reads typically outweigh the modest expanded distribution sales.

Print books have their own royalty structure entirely separate from ebook percentages. Amazon charges printing costs based on page count and ink type. They take a cut of the list price. You get what’s left. A 300-page paperback at $12.99 might net you $3 after printing and fees. Print royalties have nothing to do with the 35% and 70% ebook options.

Does Amazon pay royalties on books I give away for free?

No, free promotions generate zero royalties. Kindle Unlimited borrows during a free promo period also pay nothing. You only earn when someone buys or borrows at a paid price.

Why did my royalty amount change even though my price stayed the same?

Exchange rate fluctuations affect international sales when converted to your payment currency. Delivery fees also change slightly if you update your book file. Returns from previous months reduce your current statement total.

Do I earn royalties when libraries lend my book through Kindle Unlimited?

Libraries use a separate program called Kindle Book Lending. You earn based on pages read just like regular Kindle Unlimited borrows. The rate per page comes from the same monthly fund Amazon sets aside.

Will enrolling in KDP Select increase my royalty percentage on sales?

No, KDP Select doesn’t change your royalty rate on purchases. You still choose 35% or 70% based on price and market. Select adds income from page reads in Kindle Unlimited alongside your purchase royalties.
