Monthly earnings: $100 - $5k

With Amazon KDP, beginners typically earn around $100 per month on the low end and experienced individuals can make up to $5,000 monthly. Time invested per week, skill level in writing and niche selection, access to marketing tools and strategies, and building a reader base are key factors influencing income. Beginners starting with one book and minimal marketing efforts may see slower initial returns, while experienced authors with multiple well-promoted titles can generate substantial passive income over time.
