Here’s the truth: a successful business is something that successfully solves a problem. And that business can make more money in two ways: solving more people’s problems, or solving bigger problems. The cool thing about the EP Model is that sometimes these products don’t even have to be yours. You can generate income by recommending other people’s or companies’ services or products. This is called affiliate marketing. It’s actually how I’ve made most of my money since I started in 2008.
To create residual income, you need to create something that people will continue to buy on a regular basis long after you’ve created it. A house is a prime example of this as people will continue to pay rent for the right to live in the house. A business needs to have products that are sold over and over again rather than trading the business owner’s time for money.
Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
