Under throughput analysis, the only factor that matters is the impact of a proposed investment on the ability of a business to increase its total throughput (revenue minus totally variable costs). Under this concept, the main focus is on either enhancing throughput through the bottleneck operation or in reducing operating expenses. This analysis requires a consideration of bottleneck usage by the likely mix of products to be manufactured, and their margins. This is a much more detailed analysis than is contemplated under the more simplistic residual income approach.
Obviously, these are much higher than you’re going to get with most other investments. What’s more is that you can choose a plan that matches your investment strategy, whether your goal is Supplemental Income, Balanced Investing, or Long-term Growth. You can also look at different real estate projects and choose for yourself which ones to invest in.

Residual income valuation (RIV) which is also known as residual income method or residual income model (RIM) is an approach to or method of equity valuation which properly accounts for the cost of equity capital. The word ‘residual’ refers to any opportunity costs in excess which is measured as compared to the book value of the shareholders’ equity and the income that a firm generates after accounting for the true cost of capital is then the residual income. This approach is largely similar to the MVA/EVA based approach having similar advantages and logic.
I found this to be a fascinating and most helpful book. It was so motivating I'm already working on three new streams of income, and about to start a fourth. Forget net worth! Cash flow is much more important, particularly if you're retired. Only one slight criticism of the book. It's a bit dated, but those few parts make little difference to its overall value. If you're currently struggling with how you're going to survive after you retire, try Allen's approach. It will open your eyes.
Residual income is income that a person continues to make after the work he has put into a project has been completed. Residual income is different from linear income in that linear income refers to someone’s salary. Salaries are paid based on the number of hours someone works in the present, rather than the royalties someone can earn on work that was done in the past. To explore this concept, consider the following residual income definition.

Although adding income streams takes time, creating them within your current business is faster and easier than starting completely new income streams from scratch. This method of generating extra sources of income works well for any size business in any industry. For example, Amazon.com started by selling books. Today it sells thousands of other products including its own product, the Kindle, is a print and digital publisher, and now produces television shows. Many service-based business owners add coaching and books to their income streams.

I’ve now only got a SF rental condo and a Lake Tahoe vacation rental in my real estate rental portfolio. Although I miss my old house, I certainly don’t miss paying $23,000 a year in property taxes, another mortgage, dealing with leaks and managing terrible tenants. I drove by the other day and couldn’t believe how much noisier and busier the street was than where I currently live. I wouldn’t be comfortable raising my son there.

There are many different methods to valuing a company or its stock. One could opt to use a relative valuation approach, comparing multiples and metrics of a firm in relation to other companies within its industry or sector. Another alternative would be value a firm based upon an absolute estimate, such as implementing discounted cash flow modeling or the dividend discount method, in an attempt to place an intrinsic value to said firm.

If you’re into antiques, for example, you could check out garage sales for hidden deals then capitalize on your knowledge to turn a profit. Perhaps you’re into video games, specific brands of clothing, or something else. Whatever it is, with a little research, it’s possible to turn your knowledge into cash with an eBay store. Best of all, you can sell from the comfort of your own home.
The abstraction ignores the linear throughput of matter and energy that must power the continuous motion of money, goods and services, and factors of production. Matter and energy enter the economy in the form of low entropy natural capital, such as solar energy, oil wells, fisheries, and mines. These materials and energy are used by households and firms a like to create products and wealth. After the material are used up the energy and matter leaves the economy in the form of high entropy waste that is no longer valuable to the economy. The natural materials that power the motion of the circular flow of the economy come from the environment, and the waste must be absorbed by the larger ecosystem in which the economy exists.[20]
The second form of residual income, passive income, is often a vital part of wealth creation. There are only so many hours in each day, and when a person trades hours for dollars, there is a maximum amount of income that person can earn. For instance, if a person earns a specific amount each hour, there is a limit to how many hours are available to work. Once they reach that maximum amount of time, they cannot earn more money.
