The doctor or lawyer, for instance, could use her or his income to invest in a medical start-up or buy shares of medical companies he understands such as Johnson & Johnson. Over time, the nature of compounding, dollar cost averaging, and reinvesting dividends can result in her or his portfolio generating substantial passive income. The downside is that it can take decades to achieve enough to truly improve your standard of living. However, it is still the surest path to wealth based on the historical performance of business ownership and stocks.
You must sacrifice the pleasures of today for the freedom you will earn tomorrow. In my 20s, I shared a studio with my best friend from high school and drove beater cars worth less than 10% of my annual gross income. I'd stay until after 7:30 p.m. at work in order to eat the free cafeteria food. International vacations were replaced with staycations since work already sent me overseas two to four times a year. Clothes were bought at thrift shops, of course.

As an economic concept, residual income has a long history, dating back to Alfred Marshall in the late 1800s.1 As far back as the 1920s, General Motors used the concept in evaluating business segments.2 More recently, residual income has received renewed attention and interest, sometimes under names such as economic profit, abnormal earnings, or economic value added. Although residual income concepts have been used in a variety of contexts, including the measurement of internal corporate performance, this reading will focus on the residual income model for estimating the intrinsic value of common stock. Among the questions we will study to help us apply residual income models are the following:
Passive Wealth is like growing your own money trees! Income that is produced from what you have created, or accomplished, and it keeps bringing in money for you. HOORAY!! Goodbye slave job. 🙂 You are the head honcho, the boss. It’s your ideas and your creation. There are many ways and ideas to achieve financial success through passive income in your life. One way that opens up unlimited ways for you to achieve passive wealth is Blogging.
The underlying idea is that investors require a rate of return from their resources – i.e. equity – under the control of the firm's management, compensating them for their opportunity cost and accounting for the level of risk resulting. This rate of return is the cost of equity, and a formal equity cost must be subtracted from net income. Consequently, to create shareholder value, management must generate returns at least as great as this cost. Thus, although a company may report a profit on its income statement, it may actually be economically unprofitable; see Economic profit. It is thus possible that a value deemed positive using a traditional discounted cash flow (DCF) approach may be negative here. RI-based valuation is therefore a valuable complement to more traditional techniques.
Owning property can earn you passive income for decades to come. Once you purchase a duplex, home, or apartment building as a rental property, you’ll earn a consistent monthly income with little work. Rent should cover your mortgage, taxes, repairs, and other expenses. You’ll continue to earn income by paying off your mortgage with the rent money and saving excess rental income.

This world is a dangerous place to live, not because of the good people that often act in irrational and/or criminally wrongdoing ways within the confines of their individual minds, core or enterprise groups, but because of the good people that don’t do anything about it (like reveal the truth through education like Financial Samauri is doing!). Albert Einstein and Art Kleiner’s “Who Really Matters.”

Passive income is the Holy Grail for online marketers. It's automatic. Effortless. But, not at first. In the beginning, it's grueling. I liken this to doing the most amount of work for the least initial return. However, over time, as your passive income begins to increase, your reliance on an active income plummets. That's when the real magic starts to happen.
When fully consistent assumptions are used to forecast earnings, cash flow, dividends, book value, and residual income through a full set of pro forma (projected) financial statements, and the same required rate of return on equity is used as the discount rate, the same estimate of value should result from a residual income, dividend discount, or free cash flow valuation. In practice, however, analysts may find one model easier to apply and possibly arrive at different valuations using the different models.
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.
Maybe such a business is owning a McDonald’s franchise or something. If one has the capital (Feasibility Score 2), then the returns might be good (Return Score 6). But the Risk Score is probably under a 5, b/c how many times have we seen franchise chains come and go? Like, what happened to Quiznos and Jamba Juice? A McDonald’s franchise was $500,000… probably much more now?
As interest rates have been going down over the past 30 years, bond prices have continued to go up. With the 10-year yield (risk free rate) at roughly 2.55%, and the Fed Funds rate at 1.5% (two more 0.25% hikes are expected in 2018), it’s hard to see interest rates declining much further. That said, long term interest rates can stay low for a long time. Just look at Japanese interest rates, which are negative (inflation is higher than nominal interest rate).
To save time and effort, a person can group two or more of their passive activities into one larger activity, provided they form an "appropriate economic unit." When a taxpayer does this, instead of having to provide material participation in multiple activities, they only have to provide it for the activity as a whole. In addition, if a person includes multiple activities into one group and has to dispose of one of those activities, they’ve only done away with part of a larger activity as opposed to all of a smaller one. 
Rental properties are defined as passive income with a couple of exceptions. If you’re a real estate professional, any rental income you’re making counts as active income. If you’re "self-renting," meaning that you own a space and are renting it out to a corporation or partnership where you conduct business, that does not constitute passive income unless that lease had been signed before 1988, in which case you’ve been grandfathered into having that income being defined as passive. According to the IRS, "it does not matter whether or not the use is under a lease, a service contract, or some other arrangement."

Money from dividends, for example, are taxed at a lower rate than money from a job. A business owner who works in the company she or he founded would have to pay more self-employment payroll taxes compared to someone who merely had a passive interest in the same limited liability company who would pay only income taxes. In other words, the same income earned actively would be taxed at a higher rate than if it were earned passively.
Residual income is calculated as net income less a charge for the cost of capital. The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
