There are many different methods to valuing a company or its stock. One could opt to use a relative valuation approach, comparing multiples and metrics of a firm in relation to other companies within its industry or sector. Another alternative would be value a firm based upon an absolute estimate, such as implementing discounted cash flow modeling or the dividend discount method, in an attempt to place an intrinsic value to said firm.

Residual income can have two different definitions or applications. The first definition, a less common application of residual income, is the money that is left after monthly debts are paid. This calculation is particularly important when a person is seeking financing or a loan based on their income and available money to cover the additional debt. In this scenario, the residual income is calculated by this formula:
Airbnb is a concept that has only been around for a few years, but it has exploded around the globe. Airbnb allows people to travel all around the world and to stay in accommodations that are a lot less expensive than traditional hotels. They do this by staying with participating Airbnb members who rent out part of their homes to travelers. By participating in Airbnb, you can use your residence to accommodate guests and earn extra money just for renting out space in your home.
Opportunity cost is the basic concept at the heart of residual income. Opportunity cost refers to what you are giving up to use an asset for a particular project or investment. Let's say you start with $100,000 cash in your stock portfolio and grew that money to $104,000 by spending only a few hours per month trading stocks. Now $4,000 in profit may look just fine when you consider that you only worked, say, 20 hours for it in total. However, once you consider your opportunity cost, your little hobby will not look nearly as profitable. If banks are paying six percent for risk-free certificates of deposit, your $100,000 would have grown to $106,000 simply by depositing it in a bank. Your opportunity cost is $6,000
Obviously, these are much higher than you’re going to get with most other investments. What’s more is that you can choose a plan that matches your investment strategy, whether your goal is Supplemental Income, Balanced Investing, or Long-term Growth. You can also look at different real estate projects and choose for yourself which ones to invest in.
Lenders may be willing to remove family members from the residual calculations if a non-purchasing spouse or a working-age child has sufficient income to cover their monthly debts. This can include children who receive Social Security or disability income, child support and other forms of income, provided it’s likely to continue for at least three years.
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.
