In many instances, a business project consumes far more resources than meets the eye. Assume you are running a dog grooming business from the first floor of your two-family house and that your daughter is helping you over the weekends. The business is making $50,000 per year and you want to know whether this represents a positive or negative residual value. In this case, you must deduct from $50,000 all opportunity costs which include the money you would make if you rented the first floor of your house to a business; how much you plus your daughter would earn if you invested the same amount of time and effort into a regular job; and how much the total assets owned by the business would return every year if they were sold off and the cash proceeds were held in a bank account.
Many people in the investment world also define residual income as revenue stemming from a passive source. This revenue is created without a direct input of effort or time. The investment itself creates addition revenues without having to be managed. Some examples include royalties, dividends, interest, and rent. Take a dividend stock for example. Once the money is invested once, it will keep producing a dividend every year without having to input additional time or resources. This concept is the Holy Grail for most investors.

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.
Residual income is really the best Way of Life. It's a steady, reliable stream of income not directly dependent on the hours you work. Successful investors enjoy such freedom. Successful book authors get paid even when they don't write. The checks just keep coming uninterrupted, even when you relax. This is much better than hourly work. Much better that salaried work.  

Companies use the return on investment, or ROI, ratio as a method to measure the rate of return of a company's capital investments. ROI gives companies a means to compare the effectiveness and profitability of any number of investments. Residual income measures the net income an investment earns beyond the lowest return on its operational assets. Each of these measurements enables company management to determine the profit potential of investments in capital improvement, proposed projects or potential acquisitions.
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.

The third one is especially important. If you get a reputation for promoting services that don’t actually help your clients, your business will not grow like it could. It’s easy to get distracted by the potential money you could make, but ultimately your focus as a business owner should be solving the problems your clients have. If you keep your eye on that, you’re going to be much more likely to succeed.

For those willing to take on the task of managing a property, real estate can be a powerful semi-passive income stream due to the combination of rental and principal value appreciation. But to generate passive income from real estate, you either have to rent out a room in your house, rent out your entire house and rent elsewhere (seems counterproductive), or buy a rental property. It’s important to realize that owning your primary residence means you are neutral the real estate market. Renting means you are short the real estate market, and only after buying two or more properties are you actually long real estate.
The most liquid of the private investments are investing in equity or credit hedge funds, real estate funds, and private company funds. There will usually be 6 month – 3 year lockup periods. The least liquid of the private investments are when you invest directly into private companies yourself. You might not be able to get your money out for 5-10 years, depending on the success of the company and upcoming liquidity events.
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.
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:
