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.
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.
