So as you can see from the above example, using the concept of residual income, although Company X is reporting a profit on its income statement, once its cost of equity is included in relation to its return to shareholders, it is actually economically unprofitable based on the given level of risk. This finding is the primary driver behind the use of the residual income method. A scenario where a company is profitable on an accounting basis, it may still not be a profitable venture from a shareholder's perspective if it cannot generate residual income.
Passive Income: This is the work you do for ends that will provide you with resources for the long-term. Even after you stop contributing to the effort, you are compensated again and again. Passive income is building your own empire to gain the kind of freedom we all dream about. Unlike active, it needs a bit more dedication and hard work up front, but all of which pays off in the end.
Even if each patron only contributes a very small amount each month, it can still be a huge source of income. Take a look at the Patreon page for Kinda Funny, an internet video company. They have over 6,209 patrons which means an average of just $3 a month would be a monthly income of almost $19,000 – plus they get cheerleaders that are always happy to spread the word on their brand.
Do you know of a successful business that needs capital for expansion? If so, you can become something of a small-time angel investor and provide that needed capital. But rather than offering a loan to a business owner, you instead take an equity position in the business. In this way, the business owner will handle the day-to-day operations, while you will act as a silent partner who also participates in the profits of the business.
Rentals, just like stocks, throw off cash. With rentals we call that cash “rent”, and with stocks we call it dividends. A significant difference however is that the S&P 500 has appreciated at ~6% per year (above inflation) for the last 100 years…..Real Estate has had almost 0 growth above inflation. So are rents higher than dividends? Maybe, maybe not. But unless you got one heck of a deal, the delta in rent over dividends will have a very tough time making up for the 6% per year difference in appreciation.
Mobile apps are made to help make lives and tasks easier, to develop skills, or to entertain. There are all kinds of apps catering to different user profiles. With almost every individual owning a smartphone or an android gadget, you can make a lot of money by developing and selling your own mobile app. As this article shares, “If you can come up with something unique, you can make quite a bit of money. Simple – yet unique – apps can be pretty passive.”

In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
