What are your thoughts on an Immediate Annuity as a passive income vehicle? I suppose it’s not a great investment since you never get your principal back, but the risk is zero and the cash flow is fairly good, approaching 6% currently. And, since you are guaranteed payments for life, you may not care that you never see your principal again anyway since you’ll be dead!
I am 30 years old and am retired. Previously, I made a modest salary as an Army officer. I own three duplexes and a quadplex in central Texas (10 rental units in all), and each of the properties provide me with net rental yields in excess of 15%. The last deal is actually an infinite return as my partner paid the down payment in return for a 50/50 split on a property that would otherwise provide a net rental yield of 18%. The above net rental yields also factor in an excellent property management team who manages my properties while I pursue other investment opportunities. To date, I have never interacted with any of my tenants nor have I ever had to personally deal with any maintenance issues.
Buy a small business: A local small business, like a car wash or a laundromat, is a great way to put money down on a money-making venture. Automate it so you don't have to be on the premises unless you're collecting money. Go into a local business with your eyes wide open - study the books, especially on income and expenses, and examine water and utility bills if your venture will be open 24 hours.

I just want to add that there are additional benefits to structuring your business this way. By creating packages around specific products, you begin to be known as an expert for that product. Instead of having to learn ALL of the options out there, you can focus on just the best ones. This can help grow your client base and help you become the “go-to person” for specific platforms or services. When clients and colleagues start sending referrals your way as a result, you’ve developed yet another source of income!
Now that you’ve chosen your market, find a way to start sharing your message, whether it’s a blog or podcast or Youtube channel, or whatever platform makes the most sense for your target market. Flynn says this is where you’ll start to build a fan base — and collect subscriber emails. You don’t need to get the whole world to follow you to make this work out financially. Wired cofounder Kevin Kelly wrote an article about 1,000 True Fans, which basically says that if you have 1,000 people paying you $100 a year, that’s a $100,000 a year. “You don’t need to serve everybody,”  says Flynn.
Now that we've found how to compute residual income, we must now use this information to formulate a true value estimate for a firm. Like other absolute valuation approaches, the concept of discounting future earnings is put to use in residual income modeling as well. The intrinsic, or fair value, of a company's stock using the residual income approach, can be broken down into its book value and the present values of its expected future residual incomes, as illustrated in the formula below.

Flynn, who blogs at Smart Passive Income and discusses his secrets at the Smart Passive Income podcast, defines passive income as “building online businesses that take advantage of systems of automations that allow transactions, cash flow and growth without requiring a real-time presence. We don’t have to trade our time for money one to one. Instead, we invest our time upfront, creating valuable products and experiences for people, and we reap the benefits of that time invested later,” he says, adding, “It’s not easy. I just want to make sure that’s clear.”
The return on investment of a specific department within a company can be calculated by dividing the departmental net profits by the costs generated by that department. For example, if the sales department generates $500,000 in revenue and carries $400,000 in costs, its net profits are $100,000. The return on investment can be calculated by dividing the $100,000 in departmental profits by the $400,000 in departmental costs, which gives an ROI of 25 percent.

The main advantage of the residual income metric is that it measures excess return earned by a department in absolute terms. A positive residual income means that the department has met the minimum return requirement while a negative residual income means that the department has failed to meet it. Return on investment (ROI) is another metric which measures return in relative terms.
Once your audience has grown and you have validation that you’re offering them value, there are many ways to create passive income. You could sell digital products like ebooks or courses, take up affiliate marketing in which you promote other company’s products and earn a commission when you sell that item to your audience, build a community and charge people to be a part of it, create software and sell that, among other avenues. Ask your audience directly what would serve them best, or look at what they’re saying on Twitter, Facebook or other websites, to find out what problems they have and how you could help solve them.
What a great article . I have seen my mother and stepfather ride the roller coaster of MLM for 20 years and it was feast or famine even if you are one of the best salesmen in the world like my step father and con man Sherman Unkefer. One of the best examples is Xango that was a super huge juice craze that preached the residual income lie. Most all of the Xango heavy hitters in the day are long gone after the juice craze fizzled(no pun intended). I was privy to the Xango statements as a beneficiary of my moms trust and it was a continual nose dive in so called residual income . And another thing that they don’t tell you in MLM is that you have to constantly recruit recruit and recruit new members to keep the income flowing . Unkefer worked 80 plus hours a week to try and keep new suckers coming in. That is why the life long MLM hucksters are like Vampires, they constantly need new blood(victims) so they can keep living. These are some of the most evil sick people out there. Trust me I have seen it all.
Residual income can have two different definitions or applications. The first definition, a less common application of residual income, is the money that is left after monthly debts are paid. This calculation is particularly important when a person is seeking financing or a loan based on their income and available money to cover the additional debt. In this scenario, the residual income is calculated by this formula:
