Residual income has two real definitions. Let’s look at those first. Residual Income is income that continues to be generated after the initial effort has been expended. Compare this to what most people focus on earning: linear income, which is “one-shot” compensation or payment in the form of a fee, wage, commission or salary. The other definition for residual income is not actually a type of income, but rather a calculation that determines how much discretionary money an individual has available to spend after most monthly bills are paid. We believe that income that exceeds your expenses is called PROFIT! So, we are going to use the first definition for the sake of this document.
You need to decide which machines you want to run, get the necessary licenses to operate them (you're selling items so you need to get sales licenses and whatnot from your state), buy the machines and a truck for the items in the machines, find a supplier of the products, and then finally you can secure locations. Finally, you need to service them periodically or hire someone to service them.
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.
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.
