With $200,000 a year in passive income, I would have enough income to provide for a family of up to four in San Francisco, given we bought a modest home in 2014. Now that we have a son, I'm happy to say that $200,000 indeed does seem like enough, especially if we can win the public-school lottery to avoid paying $20,000 to $50,000 a year in private-school tuition.
BankRate.com suggests that individuals need at least $250,000 in retirement savings in order to receive just $1,000 a month in passive income. Clearly, some will struggle to save that much, and few will be able to live on such little income – especially when you take inflation and currency devaluation into consideration. This calculation is based on a 5% withdrawal rate, which is also a similar rate of return mortgage lenders will use in crediting investment income when applying for a loan. While this might sound low to some, it may be incredibly generous given how much many have actually lost on other investments. The fact remains, passive income investments don’t require as much money as many think.
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.
