Step-by-Step Guide: How to Earn Money with Amazon KDP
Step 1: Select a Profitable Niche
Don't write about what you love — find out what readers are already purchasing. Utilize tools such as:
- Amazon Bestseller Lists
- KDSpy / Publisher Rocket (paid software)
- KDP Categories Explorer
- Google Trends
Tips:
- Search for books with BSR (Best Seller Rank) below 100,000.
- Read reviews to find out what readers adore or complain about.
- Steer clear of oversaturated niches unless you provide something different.
Step 2: Plan & Outline Your Book
You don't have to write a 300-page book. Plenty of successful KDP authors create eBooks ranging between 10,000–30,000 words.
Your outline should contain:
- Title & subtitle (keyword-optimized)
- Chapter breakdown
- Core message/value
- Calls to action (if applicable)
Step 3: Write the Book (Even If You're Not a Writer)
Here are some options to get your book written:
- Write it yourself – You can use handy tools like Grammarly or the Hemingway App to help polish your writing.
- Use AI writing tools – Consider ChatGPT, Jasper, or Claude AI, but don't forget to edit afterward for a personal touch.
- Hire ghostwriters – Check out platforms like Fiverr, Upwork, or various online agencies to find someone who can bring your ideas to life.
Tip: Remember, it's all about clarity, value, and readability. Don't stress too much over "perfect grammar."
Step 4: Format the eBook for Kindle
Amazon accepts several formats like .doc, .docx, .epub, .html, and .pdf, but .docx or .epub are your best bets.
You can use:
- Atticus (paid – it's great for formatting)
- Reedsy Book Editor (free and online)
- Calibre (also free)
- MS Word + Kindle Previewer (a bit more manual)
Make sure to:
- Keep titles, headers, and page breaks neat
- Create a clickable table of contents
- Ensure fonts and spacing are consistent throughout
Step 5: Design a Professional Book Cover
Let's face it, people do judge a book by its cover.
You have a few options:
- Hire a designer on Fiverr or Upwork
- Use design tools like Canva Pro, BookBolt, or Adobe Express
Your cover should include:
- Title + Subtitle
- Author Name
- A compelling visual that fits your genre
And don't forget the Amazon cover size for eBooks: 1600 x 2560 pixels!
Step 6: Upload to KDP
Head over to https://kdp.amazon.com
Click on "Create a New Title" and choose either eBook or Paperback.
Now, fill in the following details:
- Book title
- Description (make sure it's SEO optimized)
- Author information
- Keywords (you have 7 slots—use them wisely!)
- Categories (you can select up to 2)
Next, upload your manuscript and cover.
Then, set your pricing and royalty preferences.
Understanding Amazon KDP Royalties
You have two royalty options to choose from:

| 35% | $0.99 – $200 | None | For international books |
| 70% | $2.99 – $9.99 | Yes ($0.15/MB) | Most popular option |
