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.
The first form of residual income, the leftover cash after bills and expenses are paid, is important when a person is growing their savings account or is seeking a loan or financing. When getting a loan, there must be an adequate amount of residual income available to ensure a person has the money to make the loan payments each month. If there is not adequate residual income, financing or loans will not likely be approved.
I actually spent a year and a half working as an affiliate marketer (mostly selling drumming related products – lessons, kits ect). 5 years on and one of my one page sites (which I’ve not touched) still nets me about $150 a month. I won’t be retiring off that but only really now appreciate the reverse pyramid approach to entrepreneurship (working for nothing initially but later being paid without effort!)
One of the most well known ways of generating residual income is through ownership of stock in a publicly-traded company. Residual income streams can also include things like royalties from the sale of a book or song. Today, there are also several online platforms like Lending Club or Prosper that allow you to invest in personal or small business loans.
Venture debt ($12,240 a year): The first venture-debt fund has returned almost all my initial capital, so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend's first fund, so I'm hoping there's less risk in the second fund, given he has four more years of experience on top of his 12-plus years of experience running a venture-debt portfolio for another company.
It’s obvious that stocks outperform real estate in terms of capital gains, but I would like to see S&P compare to Real Estate in SF, Manhattan, LA. Our house in NC was $80,000 20 years ago. It’s only $150,000 now. Same house in Santa Monica went from $200,000 to $1.8 million. People who happen to bought real estate in major metropolitan would have a natural positive association with real estate investment.
There are three main categories of income: active income, passive income and portfolio income. Passive income has been a relatively loosely used term in recent years. Colloquially, it’s been used to define money being earned regularly with little or no effort on the part of the person receiving it. Popular types of passive income include real estate, peer-to-peer (P2P) lending and dividend stocks. Proponents of earning passive income tend to be boosters of a work-from-home and be-your-own-boss professional lifestyle. The type of earnings people usually associate with this are gains on stocks, interest, retirement pay, lottery winnings, online work and capital gains. 

I just found your site & so far I like what I see. I am 50 years old & will be retiring at the end of Jan 2019. I turn 51 the following month. I will have a pension income of $60,000 per year & an additional $5,400 from a survivors benefit. I was able to save $200,000 in a deferred comp program through my employer & wish to know what to do to generate a passive income? I can leave it in the plan which will generate about 3.5% or invest it. My concern is the tax liability of taking out a large sum from that fund & leaving me less to invest. I do have an opportunity to invest in a bar/restaurant with family (my main concern) that currently generates $120,000 annually for an absentee owner. It would be a 3 way partnership if I did that. I do like your idea of creating my own product such a blog with a goal of $12,000 to $18,000 passive income I feel that may be my best option. Any thoughts or advice would be greatly appreciated.
The vast majority of people imagine working a forty hour week, and then earning a pay check for the job they have done. That is, in fact, how most people support themselves year after year. But did you know that it is possible to continue earning income even after you stop working. Creating a stream of residual income might be something you want to take a look into and get some more information on. 
When withdrawing money to live on, I don’t care how many stock shares I own or what the dividends are – I care about how much MONEY I’m able to safely withdraw from my total portfolio without running out before I die. A lot of academics have analyzed total market returns based on indices and done Monte Carlo simulations of portfolios with various asset allocations, and have come up with percentages that you can have reasonable statistical confidence of being safe.
Department C has earned net operating profit of $300 million for the FY 2011 while department P has earned operating profit of $130 million for the same period. Department C had opening operating assets of $1 billion and its closing operating assets are $1.1 billion while department P had opening operating assets of $0.5 billion while its closing operating assets are $0.7 million.
Add Leverage (Mortgage) and you greatly increase the ROI especially from the perspective of using Rents (other peoples money) to pay down the mortgage and increase your equity in the property over time. At this point then yes price appreciation is secondary bonus and we have an arguement of how and why Real Estate can be better than Growth Stocks in some scenarios and for some investors.
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.
