Online learning platforms have become extremely popular in recent years with people using platforms like Coursera, Lynda, and Udemy for learning courses about their specific interests. If you are knowledgeable in any field, whether it's web programming, photography or digital marketing, you can create a course on platforms like Udemy or Unacademy and earn money when users register for them.
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.
This is another way of ensuring regular income for a period of time. Let us say, you are uncomfortable with the idea of investing in high dividend yield stocks as they generally do not give price appreciation. Also, there is no assurance on dividend yields as dividends may fall if the profits of the company fall. Another way out is to invest the money into a debt fund and pay yourself through an SWP. Let us assume that you did the same SIP and ended up with Rs.1.41 crore at the age of 45. Now you want to pay yourself a regular income for a period of 15 years till your retirement. Here is how it will work.
If you want to top up your income without taking on a strenuous second job, your first port of call should be your very own skillset. If you have a natural talent that could help others, you have an instant “in” to easy money. Whether you’re a gifted guitarist, mathematical genius or speak a second language, almost any talent can be turned into cash. Offering one-to-one coaching is a flexible way to make a solid hourly rate, and enables you to take on as much or as little work as you wish. Find local clients by placing adverts in the library, schools and community bulletin boards and share your talent in exchange for a fee.

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.

What spurred this blog post was an idea put forth by my friend at ESI Money in which he talks about how the first million is the hardest. ESI shares how his net worth growth has accelerated. The first million took 19 years of work (the clock starts when he started working, not at birth!) but the 2nd million took just 4 years and 9 months. J Money took this same idea and started at $100k, which took him 7yrs 11mos. Each of the next $100k milestones took close to 18 months each to reach.
Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.
My returns are based on full cash purchase of the properties, as it is hard to compare the attractiveness of properties at different price ranges when only calculating down payment or properties that need very little rehab/updates. I did think about the scores assigned to each factor, but I believe tax deductions are a SIGNIFICANT factor when comparing passive income steams.

I would throw in some caution here: if your spouse works at the same company, or in the same industry as you, you are not diversified, and should something happen, you could be in a world of hurt.  Companies do go out of business, companies do lay employees off.  There is nothing wrong with working together, but realize that you are not diversified and you should be trying to maximize other income streams as a result.
You can provide tuitions to many school or college going students if you are good in a particular subject. Teaching students is also a great way to earn money. This way you can also enhance your knowledge about the subject you were passionate about. You can also go online and register yourself at websites and portals. This way you can maximize your reach.
Most of us think of investment income as just the cash flow we get from bank interest, bonds, share dividends and property rents, some of which comes via a super pension.  But a more complete view is to also consider how growing the value of your investments can add to your spending potential.  This total return approach generates income from both income and growth to optimise spending from your portfolio across all market cycles, aligning cheap and expensive investments to your goals.
