4. Calculate how much passive income you need. It's important to have a passive-income goal — otherwise, it's very easy to lose motivation. A good goal is to try to generate enough passive income to cover basic living expenses such as food, shelter, transportation, and clothing. If your annual expense number is $30,000, divide that figure by your expected rate of return to see how much capital you need to save. Unfortunately, you've got to then multiply the capital amount by 1.25 to 1.5 to account for taxes.
Another thing that belongs firmly at the top of passive income ideas lists is affiliate marketing, where you earn a commission for each product or service that you recommend. My new focus these days is on Amazon affiliate websites. The idea is that you talk about, or review products that you can find on Amazon. People visit your website, click on some of your Amazon affiliate links, buy a product on Amazon and you get a commission for any sales, not only for that specific product but for anything they buy within a 24-hour period.
My favorite type of semi-passive income was rental property because it was a tangible asset that provided reliable income. As I grew older, my interest in rental property waned because I no longer had the patience and time to deal with maintenance issues and tenants. Online real estate became more attractive, along with tax-free municipal-bond income once rates started to rise.
The reason I prefer e-books is, with e-books you write the book once and make money forever without worrying about print or inventory. At the moment, I have 3 e-books selling on this blog and the process to get any of them is simply automated. Once anyone makes a purchase, they get delivery within minutes. So I could sleep or spend the whole day at the beach and I would still be making money. Passive income!
