Popular examples include rental income, dividends, royalties, and online monetization methods. But in this article, we’ll focus on passive income ideas that start working fast.

• You can start earning within 30–60 days
• Low to moderate startup costs
• Leverages existing skills or digital tools
• Can be automated or scaled
