Successful websites almost always have multiple streams of residual income. Setting up a website that brings income with minimal work is the dream of everyone doing business online, and if you are a website business owner who has the knowledge it takes to build and market a business website, you can also gain multiple streams of residual income that will keep generating income long after the initial investment has been made.
Many people talk about passive income and create the impression that you never have to do anything to keep that income going. The truth is that you will normally have to keep your eye on things if you want it to run smoothly. For example Richard Branson doesn’t run any of the 400+ companies he started but he goes over the numbers each day to make sure they’re performing well and calls the CEO if there are any problems.
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.
