“[T]he stream of continuing payments that are earned by Brad and/or Karen from the commissions (current and future) earned by the brokers within a book of business. Residual income arises from all sources of income relating to or derived from an identified book of business, including commissions earned by the brokers within that identified book of business from any source whatsoever.”
Passive income is attractive because it frees up your time so you can focus on the things you actually enjoy. If a doctor wants to earn the same amount of money and enjoy the same lifestyle year after year, they must continue to work the same number of hours at the same pay rate—or more, to keep up with inflation. Although such a career can provide a very comfortable lifestyle, it requires far too much sacrifice unless you truly enjoy the daily grind of your chosen profession. Additionally, once you decide to retire, or find yourself unable to work any longer, your income will cease to exist unless you have some form of passive income.
Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
