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.
Even if each patron only contributes a very small amount each month, it can still be a huge source of income. Take a look at the Patreon page for Kinda Funny, an internet video company. They have over 6,209 patrons which means an average of just $3 a month would be a monthly income of almost $19,000 – plus they get cheerleaders that are always happy to spread the word on their brand.
4. eCourses: A step up from an eBook is an eCourse. These are a more thorough training that you can offer in a text format and typically include supplemental formats like video, worksheets, audio and more. This opportunity involves more work and likely an investment into a platform for delivery like Teachable, but you can also ask a lot more money. If you have been around the blogging world for any period of time you know it’s not unusual to see eCourses being sold for several hundred dollars if not more.

Further, the clarified order awarded Karen sixty percent of the residual income that was earned from the income and commissions generated by the brokers within the first category, and after the date of divorce. However, the order also stated that Karen was not entitled to any of the residual income generated by the second or third category. Brad filed for a new trial, but the trial court denied it. He appealed, and the appeals court ultimately affirmed the trial court’s clarified order.
Residual income valuation is a process of business equity evaluation that accurately calculates the cost of equity capital. The primary application of this method is to calculate a rate of return that provides investors and managers a means to measure the compensation for their opportunity cost. Even if a project shows a profit, the residual income valuation may show that this specific project may not have been as profitable as another opportunity.
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.
