Passive income differs from earned income and portfolio income in a variety of ways. Passive income is generally defined as a stream of income earned with little effort, and it is referred to as progressive passive income when there is little effort needed from the individual receiving the passive income in order to grow the stream of income. Examples of passive income include rental income and any business activities in which the earner does not materially participate during the year.
Finally, when looking around for the right personal finance software that meets your needs, make sure that you’re comfortable with the program’s interface. It shouldn’t be expected that you recognize every single feature instantly, but if the features don’t seem readable and manageable to you, then you’re not as likely to use it and get the full benefits.

YouTube brought in nearly $4 billion in estimated ad revenue in 2018. So you can earn a potentially large income by uploading videos to the platform and then watching those ad dollars roll in. You may need or want to upload videos regularly, which isn’t especially passive. But you don’t need to provide a specific product or service directly to customers.

In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
