Ebook Royalties Explained: How Much Do Authors Actually Earn Per Sale?
You price your ebook at $4.99 and assume about five dollars lands in your account every time someone buys a copy. It doesn't. Net of delivery fees, and that gap surprises almost every first-time author.
Between the retailer's cut, file delivery fees, and whatever your publishing partner charges, the number you actually keep depends on choices you make long before launch day. Make them well and a modest book can earn steady money. Make them blindly and you can sell hundreds of copies and still wonder where it all went.
This guide walks through how ebook royalties really work, using actual publishing math instead of vague percentages. Whether you're comparing a book publishing company, weighing self-publishing services, or just trying to figure out if your book can pay for itself, you'll know what to ask and what to expect.

What Are Ebook Royalties (and What Aren't They)?

A royalty is the share of each sale that gets paid to you, the author, after the retailer and anyone else in the chain takes their cut. On an ebook sale the money can pass through up to three hands:
Two things are worth getting straight early.
  • Royalty is not profit. Editing, cover design, formatting, and marketing all cost money up front. Royalties only turn into profit once you've earned that spending back.
  • The percentage isn't always applied to the price the reader paid. Some stores deduct costs first, which is why a "70% royalty" rarely equals 70% of the sticker price.

How Do Ebook Royalties Work on Amazon KDP?

Look closely at the last two rows. Go one cent over the limit and your royalty drops by almost half. That's the kind of detail that decides whether your price makes sense.
Now take an illustrated ebook that weighs 20 MB and sells for $4.99. The delivery cost is $3.00, so the 70% option pays 0.70 × $1.99, or $1.39. The 35% option pays $1.75. In that case, the "lower" rate actually wins.
KDP also has eligibility rules, such as keeping your ebook price meaningfully below the print edition. Rates and price bands can change, so check Amazon's official KDP pricing page before making permanent decisions. For your own numbers, Berg Publisher's KDP royalty calculator does the arithmetic for you.
One last practical point. Ebook royalties don't arrive the day a book sells. Expect payment roughly two months after the month of the sale, so don't plan your launch budget around instant income.
  • 70% option: you earn 70% of the list price minus a delivery cost. Your price has to fall between $2.99 and $12.99 on Amazon. (The ceiling used to be $9.99. Amazon raised it in July 2025.)
  • 35% option: you earn 35% of the list price with no delivery cost. It applies to prices outside the 70% band, and you can also choose it on purpose.
Delivery cost is $0.15 per megabyte of your ebook file on Amazon. A text-only novel is usually well under 1 MB, so the fee is pennies. An image-heavy book is a different story, and we'll get there in a minute.

The formula looks like this:
70% royalty = 0.70 × (list price − delivery cost)

Here's what it means per sale, assuming a 1 MB file sold in the US:
List priceRoyalty optionYou earn per sale
$0.9935%about $0.35
$1.9935%about $0.70
$2.9970%about $1.99

$6.9970%about $4.79
$9.9970%about $6.89
$12.9970%about $8.99
$13.0035%about $4.55

How Do Other Retailers and Distributors Compare?

Amazon isn't the only store. Apple Books, Kobo, Barnes & Noble Press, and Google Play Books all sell ebooks too, and many of them pay around 70% on qualifying prices. The exact terms vary by store and by price, so treat that as a ballpark and confirm the current rules on each platform.
If you publish through a distributor such as IngramSpark, the distributor takes its own slice before the money reaches you. You trade a slightly smaller cut for wider reach, including libraries and bookstores that won't buy from Amazon. Our comparison of KDP vs IngramSpark goes deeper, and the post on the ebook royalty calculator for KDP, IngramSpark, and Draft2Digital shows the numbers side by side.
Amazon's KDP Select program adds another wrinkle. It asks for ebook exclusivity for a set period in exchange for extra promotional tools. Whether that trade makes sense depends on your genre and goals.

What Affects How Much You Earn Per Sale?

Your ebook royalty per sale isn't one number. It's the result of several moving parts:
  • List price. Pricing inside or outside a retailer's royalty band changes your rate.
  • File size. Images, charts, and embedded fonts add megabytes, and megabytes add delivery cost on the 70% option.
  • Territory and tax. Sales in countries with VAT or similar taxes are calculated on the price after tax.
  • Print factor. Authors and hardcover are paid differently: a percentage of the list price minus printing cost. A $9.99 ebook can easily earn more per sale than a $9.99 paperback.
  • Where you sell. Selling direct to a retailer pays differently than selling through a distributor.
  • Who publishes you. Some companies charge a flat fee and let you keep your royalties. Others keep a share. Always ask which one you're signing.

What Royalty Mistakes Do Authors Make Most Often?

These come up again and again, and almost all of them are avoidable.
  • Treating royalty as profit. A book that has sold 300 copies hasn't necessarily paid for itself. Count your production costs first.
  • Ignoring file size. Illustrated and children's books can lose a big share of each sale to delivery costs. Run the numbers on both royalty options.
  • Pricing a book too high. As the table shows, crossing the 70% ceiling can cut your rate in half.
  • Using a free ISBN without understanding the trade-off. A retailer-supplied ISBN can limit where the book is distributed and who is listed as publisher. Here's the breakdown on free KDP ISBN vs. your own, and ISBN and copyright registration explain the setup.
  • Skipping the editor to save money. Typos and structural problems lead to weak reviews. Weak reviews lead to fewer sales. That cycle rarely lasts.
  • Signing a contract that quietly shares your royalties. If a company's pricing seems too good to be true, read where its money comes from.

Self-Publishing, Hybrid, or Traditional: Who Pays You What?

How you publish changes both your upfront cost and your per-sale earnings. A rough comparison:
PathUpfront cost to youTypical ebook earningsRights
Self-publishing (direct to retailers)You pay for any services you hire35% or 70% of list price under each store's rulesYou keep them
Hybrid publishing servicesYou pay a fee for production and distributionDepends on the contract; some partners keep a percentage per saleVaries, so read the terms
Traditional publisherUsually none, and sometimes an advanceOften around 25% of net receipts on ebooks, though contracts differUsually licensed to the publisher for years
None of these is automatically the best. Traditional publishing offers prestige and bookstore placement but gives up control and a larger royalty share. Self-publishing gives you the biggest share per sale but puts the work on you. A hybrid publishing model sits in the middle. If you're weighing the three, our pages on self-publishing vs traditional publishing and hybrid publishing explain how each one works in practice.

FAQs

1. How much does an author make per ebook sale?

It depends on price, platform, and file size. On Amazon, a $4.99 ebook with a small file earns about $3.39 under the 70% option and about $1.75 under the 35% option.

2. Is the 70% royalty option always better than 35%?

No. The 70% option subtracts a delivery cost based on file size, so a large, image-heavy ebook can earn more on the 35% option.

3. Do I keep my royalties if I use a book publishing company?

That depends on the contract, so ask before you sign. Some companies take a percentage of every sale. With Berg Publisher, authors keep ownership of their work and their royalties, though the retailer's own cut still comes off first.

4. How long until I get paid?

Most retailers pay monthly, and the money usually arrives about two months after the month in which the sale happened. Check each platform's payment schedule for specifics.

5. Can I publish my book myself and keep more of the money?

Yes, and many authors do. The trade-off is time and cost; you'll need to arrange editing, cover design, formatting, and marketing on your own or pay for them separately. Professional book publishing services exist to take that load off you without taking your rights.
