IM Score: 54

Publishing eBooks can be one of the best sources of passive income for beginners given its low upfront costs and minimal ongoing effort. Amazon’s Kindle Direct Publishing (KDP) simplifies this by allowing authors to easily convert and publish their manuscripts as eBooks or paperbacks. Authors retain control over content, pricing, and royalties, and benefit from Amazon.com Inc (NASDAQ:AMZN)’s massive marketplace. KDP offers royalty rates of 35% or 70%, based on pricing and distribution.
