About This Side Hustle

Amazon's Kindle Direct Publishing (KDP) allows anyone to publish ebooks and paperbacks with zero upfront cost. You earn 35-70% royalties on every sale. Popular niches include low-content books (journals, planners, coloring books), nonfiction guides, and fiction series. Many KDP publishers build portfolios of 20-50+ books that collectively generate substantial monthly passive income.

Earning Potential

A single KDP book typically earns $50-500/month depending on the niche. A portfolio of 10-20 books can generate $1,000-5,000/month. Top KDP publishers with 50+ books report $10,000-30,000/month in passive royalties.
