This equation is pretty simple and incredible useful for management because it looks at one of a department’s key components of success: its required rate of return. This component helps management evaluate whether the department is making enough money to maintain, close, or expand its operation. It’s essentially an opportunity costmeasurement based on the trade off of investing in capital in one department over the other. For instance, if management can invest company revenues in department A and earn a 15% return, department B would have to make at least 15% in order for the management to consider the investment. If department B doesn’t meet minimum 15% return rate, it might be shut down or redirected.
Wouldn’t it be nice to earn money while not working? That money is called residual, or recurring, income. It's what can happen after you put a lot of time, effort and sometimes money into a job to continue to get paid for the work months or years after it's done. (Salary jobs are part of linear income. This income is directly related to the number of hours you work. If you work 40 hours, you get paid for 40 hours of work.) Once you set up your business to earn residual income, you continue to make money while doing other things – maybe even starting a new business to generate more residual income!
On August 4, 2003, Brad and Karen Murray’s marriage ended. They continued arguing over their assets for another four years. Brad worked as an independent broker for Ameriplan – a marketing company specializing in providing discounted rates on services related to healthcare. As part of his job, Brad sold monthly memberships to Ameriplan’s discounted health plans. He also recruited other brokers to do the same.
In expensive cities like San Francisco and New York City, net rental yields can fall as low as 2%. This is a sign that there is a lot of liquidity buying property for property appreciation, and not so much for income generation. This is a riskier proposition than buying property based on rental income. In inexpensive cities, such as those in the Midwest, net rental yields can easily be in the range of 8% – 12%, although appreciation may be slower.
But when so many turn down leasing one and one-half acre for one Wind Turbine for each 80 acres, that lease certainly does not materially affect the rest of the Farm or Ranch grazing pasture and the lease pays much more than the farm crow or grazing pasture lease, just because some lawyer said the lease was too long: 30 years plus 30 year option = 60 years, and the wind turbine company has selling production/electricity contracts for the next 150 years – which is needed to obtain financing!

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.
