Yes, self-published books can make money. The market you pick matters most, and a strategy I haven’t covered before, bundling, can stretch four manuscripts into seven books. Below I cover how I choose a market, what to optimize, and how bundling works under KDP’s rules.
Why don’t most how-to guides show how to make money?
Maybe you want to make money online, or you have book ideas, and you wonder whether it will be worth it.
When I started years ago, I followed a how-to-self-publish book step by step and released my book. I saw only a small trickle of sales. A few key strategies were missing from the book, and they decided whether I would make money. I found them through programs, books, forums and YouTube. They are not obvious.
Since then I have made plenty of money from my books. Yes, they make money if they are optimized. For a sense of the range, the Authors Guild’s 2023 survey found full-time self-published authors had a median income of $12,800 from their books in 2022. That is a median, so half earned less, and it is why I treat this as a skill you build over several books. I go into the numbers in can self-publishing be profitable and how much a self-published book can earn.
How do I find a market that makes money?
The market is the most important thing. You want a lot of hungry readers looking for books on a topic where there aren’t many books. That gap between high demand and low supply is the market to jump into. I use KDSpy to find those markets.
Then optimize the rest:
- A sales page: the description should focus on what makes people want to buy, not only what the book is about.
- A great cover.
- Keywords that help people find the book, and an optimized title.
- A table of contents that shows in the preview, and good formatting. I recommend Atticus for formatting.
- Reviews after launch, and then ads.
Even if you only get the market right and do an okay job on the rest, you can still see sales and profit. A terrible market is hard to recover from.
The more books you have, the more money you make, and you get better at optimizing each one.
What is bundling and how do I do it?
Say you write 4 books on a topic, such as Vegan Food for Beginners, Vegan Advanced Cooking, and so on. Call them A, B, C and D. You make three bundles from them: AB, CD and ABCD. That is 4 manuscripts and 7 books, and you optimize all 7.
Then you push into every format that fits: Kindle ebooks, KDP paperbacks, hardcovers, IngramSpark for wider print distribution, and audiobooks. Ebooks can also go wide through an aggregator such as Draft2Digital.
On Amazon, follow KDP’s boxed set and bundle guidelines, which apply to ebooks with two or more titles:
- Say in the title and the first paragraph of the description that it is a multi-book set, and list each included book.
- If you use an ISBN (KDP recommends one), give the bundle its own, not one from an included book.
- Include a linked table of contents at the start, in series order.
- Don’t use keywords or author names of books that are not in the bundle.
- Show on the cover that it contains multiple books.
Amazon removes content that doesn’t follow these guidelines, so read them before you upload. For series pages and why paperback box sets are not available, see how to publish a series of novellas and box sets on KDP. You are covering the market with 7 books from 4 manuscripts, optimizing each, and the sales come from every channel. If you are still deciding where to publish, see is KDP self-publishing right for you.

What price earns the 70% royalty on a bundle?
Price matters as much as the bundle. On Amazon.com the 70% royalty option applies to ebooks priced from $2.99 to $12.99 (effective 07-Jul-26), and delivery costs still apply to it. The 35% option allows prices up to $200.00 (KDP ebook royalty options). A bundle priced above $12.99 can only use the lower rate, so check the price against the band before you set it.

It varies a lot. The Authors Guild 2023 survey found a median of $12,800 from books for full-time self-published authors in 2022, so half earned less.
Can I bundle my books on KDP?
Yes, as an ebook. KDP's boxed set and bundle guidelines apply to ebooks that contain two or more titles. The title and description must say it is a multi-book set, the table of contents must link to each book, and an ISBN is recommended.
