The Kindle Delivery Fee: How It Quietly Cuts Your Royalty

The Fee Almost Nobody Reads About

When you choose the 70 percent royalty option on Kindle, Amazon deducts a delivery fee from every sale before it calculates your cut, and most new authors never notice it. The fee is charged per megabyte of your book file, currently 0.15 dollars per MB in the United States, and it applies only to the 70 percent tier, not the 35 percent one. For a lean text novel the impact is a few cents, but for an image-heavy book it can quietly erase a meaningful slice of your income on every single copy sold. Understanding this line item is the difference between guessing at your royalty and knowing it. The good news is that once you finish a manuscript with a free AI book generator, the file size is entirely within your control.

How the Math Actually Works

The formula is straightforward: your royalty equals 70 percent of the list price, minus the delivery fee, minus applicable taxes. A 2.99 ebook that is 1 MB in size loses about 0.15 dollars to delivery, leaving roughly 1.94 dollars instead of the 2.09 you might have expected. Scale that to a 20 MB illustrated book and the fee balloons to 3 dollars, which can wipe out the entire royalty on a low-priced title. This is why cookbooks, children's books, and photo-heavy nonfiction sometimes earn more on the 35 percent plan, which carries no delivery fee at all. Running both numbers before you publish takes two minutes and can change which royalty option you pick.

• 70 percent tier: royalty is list price times 0.7, then minus 0.15 dollars per MB.
• 35 percent tier: no delivery fee, which can win for very large files.
• Break point: compare both tiers whenever your file exceeds roughly 3 to 5 MB.

What Actually Bloats Your File

Text is nearly weightless; images are where megabytes hide. A pure prose novel typically lands under 1 MB even at ninety thousand words, so a text-first author has almost nothing to worry about. The culprits are high-resolution cover thumbnails embedded in the interior, decorative chapter headers saved as large PNGs, and photographs dropped in at print resolution when screen resolution would look identical on a Kindle. When you generate a full book with AI, the draft is plain text and weighs almost nothing, so any bloat you see later came from images you added during formatting.

Practical Ways to Shrink the File

Compress every image before you build the ebook. Resize photos to around 1600 pixels on the long edge, save them as optimized JPEGs at 80 percent quality, and use PNG only for line art that truly needs it. Strip embedded fonts you are not using and avoid pasting images from a word processor, which often keeps them at full resolution. These steps routinely take a 15 MB file down to 2 MB with no visible loss on any e-reader screen. Because the text from an AI book writing tool starts clean, your only job is disciplined image handling. Our paperback formatting guide covers the print side of the same discipline.

When to Simply Accept the Fee

Not every book should be stripped bare. If images are the product, as in a photography book or an illustrated children's title, compressing them into mush destroys the value you are selling. In those cases keep the quality high, price the book to absorb the fee, or move to the 35 percent tier where the fee vanishes. The point is to decide deliberately rather than let Amazon surprise you at payout. A thoughtfully produced book, drafted quickly when you write your book with AI and formatted with care, earns more because you chose the plan on purpose. You can try it free and have a compact draft ready to format the same afternoon.

Delivery Fee Across Marketplaces

The per-MB rate varies by store, so a file that costs 0.15 dollars in the US may cost a different amount in the UK, Germany, or India. Amazon lists each marketplace's rate in its royalty documentation, and the differences are small per copy but add up across a catalog selling internationally. If you publish widely, keeping files lean protects your margin in every currency at once. This is another reason the compact output of this book generator is an advantage: a small file is small everywhere. You can build and format several titles quickly at aibookgenerator.org and apply the same lean-file habit to each.

Fold It Into Your Pricing Decision

Because the fee interacts with price, treat the two together. A larger file may justify nudging your list price up a dollar so the post-fee royalty still hits your target, or it may push you toward the fee-free 35 percent tier. The key is to calculate your true take-home per sale, not the headline 70 percent, before you commit. Our KDP pricing playbook walks through the full royalty band, and the delivery fee is simply one more variable in that same equation. When you know your real number, you can price with confidence, and a title you generate a full book with AI gives you a lean starting file to price around.

Small Files, Real Money

None of this is complicated once you see it. Keep prose books lean and the fee is a rounding error; treat image files with intention and you protect real margin on every copy. The habit costs nothing and pays out for the life of every title you publish. Start by drafting the manuscript itself, which you can do right now with the AI Book Generator before you ever touch formatting. When you are ready to scale into a catalog where these small optimizations compound, the pricing page shows the plans, and the book generator hub is the fastest place to begin your next title. A lean, well-priced book is one you can build tonight with the AI Book Generator and profit from for years. Try the free plot tools below to sketch your next idea before you draft.
