Cultivate little-known DIY projects and ideas that are needed by consumers.  For example, provide tips and tricks on self-improvement or weight loss. Develop your website to cater to the type of information you want to sell. Build your e-mail newsletters at the same time and up-sell a monthly subscription. You will have effectively rolled three services into one great profit.

One of the reasons starting a blog is such a draw for people these days is the ability to generate “hands off” money. We are all longing to get out of the rat race. We want to travel, volunteer at our kids’ school, have time to do the activities we truly love instead of sitting in traffic on the way to and from work. And blogging can help make that happen.

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.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
