Many bloggers and social media influencers build significant residual income through affiliate partnerships. If a blogger promotes or mentions a product on their site, and readers purchase the product through the link provided, the blogger earns a percentage of the revenue. The same goes for social media influencers. If someone promotes a product on Instagram and their followers purchase it through their link, the Instagrammer would receive a portion of that revenue.

I had to get out. I actually had this random Facebook ad come up in my news feed (go figure) and it eventually led me to a webinar that taught on how to start an email marketing business (which is, by the way, the most profitable form of affiliate marketing – or ANY marketing for that matter). I listened through the whole 2 hours, completely mesmerized. By the end of it, I knew what I was going to be focusing on to help my family out of the pit of debt we were in and into a world free of financial stress. I didn’t know if it would actually work, but eventually it lead to EXCESS income!

By participating in Airbnb, you can use your residence to accommodate guests and earn extra money just for renting out space in your home.
Investing in real estate: Investing in real estate offers more passive income cash potential - but more risk - than investing in stocks or bonds. You'll need substantial amounts of cash to invest in buying a home -- it usually takes 20% down to land a good home mortgage loan. But history shows that home prices usually rise over time, so buying home a for $200,000 and selling it for $250,000 over a five-year time period, for example, is a reasonable expectation when investing in real estate.
​I’ve been into home décor lately and I had to turn to Etsy to find exactly what I wanted. I ended up purchasing digital files of the artwork I wanted printed out! The seller had made a bunch of wall art, digitized, and listed it on Etsy for instant download. There are other popular digital files on Etsy as well such as monthly planners. If you’re into graphic design this could be an amazing passive income idea for you.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return.
