On August 4, 2003, Brad and Karen Murray’s marriage ended. They continued arguing over their assets for another four years. Brad worked as an independent broker for Ameriplan – a marketing company specializing in providing discounted rates on services related to healthcare. As part of his job, Brad sold monthly memberships to Ameriplan’s discounted health plans. He also recruited other brokers to do the same.

Department C has earned $142.5 million residual income as compared to $40 million earned by department P. Residual income allows us to compare the dollar amount of residual income earned by different departments. Since the residual income in both cases is positive, we conclude that both have met the minimum return requirements. However, with residual income is not easy to compare performance.

Here's another example. If a person owns apartments that are rented out at a profit, they earn money each month without working a specific number of hours. If the owner earns $100/month net income from each apartment, the determining factor is how many apartments they own, not how many hours they work. Therefore, they may own 1 apartment and make $100 net income each month, or they could own 500 apartments and make $50,000 ($100 per apartment) each month.
If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!

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:
​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!

Perhaps a coworker purposefully tries to make your life miserable because they resent your success. Maybe you get passed over for a promotion and a raise because you weren’t vocal enough about your abilities, and mistakenly thought you worked in a meritocracy. Or maybe you have a new boss who decides to clean house and hire her own people. Whatever the case may be, you will eventually tire.


I just can’t seem to get my head around creating my own online product. When you talk about it, you make it sound like its mostly just about putting in the time and plugging away at it. Problem is I can never seem to come up with any ideas for a site or product that seem remotely unique or compelling or that I have any special knowledge about. The stuff I do know about is pretty commodity type knowledge that can mostly be found on thousands of sites on the internet already. Any tips on discovering what your “unique angle” is? I mean, you have a pretty compelling and somewhat unique personal story of working on wall street and then walking away at a young age.
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.
When looking at income in the future, shouldn’t we be looking at what is going to happen and determine if that is what we want life to look like? We need to work backward from that point until we reach today, viewing our decisions with money as the pre-cursor of tomorrow? The reason we even talk about residual income is that’s the goal of retirement or what we like to call time freedom.
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.
