Passive income: NO

Starting a Substack newsletter business has the potential to earn passive income over time, but it typically requires consistent effort and dedication before reaching a truly passive state. While some successful newsletter writers have automated certain processes and outsourced tasks to make their businesses more passive, achieving a fully passive income stream may not be common. It often depends on factors such as niche, audience engagement, and content quality. Initial setup costs range from $0 to $100 for basic equipment and tools. Most people who earn passive income from a Substack newsletter have put in significant upfront work to build a loyal subscriber base and high-quality content. While it is possible for some individuals to eventually earn passive income from a Substack newsletter, it may not be a guaranteed outcome for everyone.
