Renewable subscriptions. Most of the tools and resources we use, in order to manage our online projects, are subscription based. These range from domain hosting providers, to task management solutions, to SEO (search engine optimization tools). Our providers generate residual income each month, by cashing into the renewable subscriptions purchased by their clients. However, this subscription payment model has been successfully used in all sorts of segments of the e-commerce industry, from cosmetics (subscription-based sample boxes) to food (home-deliverable monthly gourmet baskets). The initial investment of creating a functional e-commerce platform can run high, but with appropriate leverage, it can rake in major money.
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.
