Finally, I imagine the biggest debate with my ranking is Creating Your Own Product as the #1 passive income source. If most people have never created their own product, then it’s easy to give it a thumbs down. There won’t be much complaint about Private Equity Investing being in last place because most people are not accredited investors. But given I believe that plenty of people can create their own product if they try, pushback is inevitable because a lot of people simply don’t try!
The return on investment of a specific department within a company can be calculated by dividing the departmental net profits by the costs generated by that department. For example, if the sales department generates $500,000 in revenue and carries $400,000 in costs, its net profits are $100,000. The return on investment can be calculated by dividing the $100,000 in departmental profits by the $400,000 in departmental costs, which gives an ROI of 25 percent.
The first time I did affiliate marketing was way back in the day on my architecture exam website. I connected with a company that sold practice exams, which gave me $22 for every person who bought one of their exams via my site. Since then, I’ve generated over $250,000 simply by recommending that product alone. Again, this is a product that was not mine, but one that has still been helpful to my audience. This was all done with thousands of visitors a month. Not millions, or even hundreds of thousands.
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.
