I also noticed that in your passive income chart at the bottom that you don’t include your internet income other than sales from your book. Is there a reason for that? Do you not consider is passive because you are actively blogging all the time to create it? Or do you just not want readers to know how much money you generate from blogging activities?
Well written piece, but I question the core premise. Why the fascination with maximizing “income” (passive or otherwise). Shouldn’t the goal simply be to maximize long-term after tax growth of your entire portfolio? If this takes the form of dividend paying stocks, so be it. But what if small caps are poised to outperform? What if you want to take Buffet’s or Bogle’s advice and just buy a broad market index like the S&P 500, (no matter what the dividend because you’ll just have it automatically reinvested to avoid the transaction fees).
Some good writing here! I am a realtor myself and frequently get in touch with clients that consider buying a realty estate a conservative of investing. I once heard of a transport company in Vienna, Austria, which focused their entire profit on buying eventually every house available in the downtown for about 80 years. That must be some of a passive income!

Once I started blogging and connecting with other bloggers in the personal finance space, I saw how much potential was out there. And honestly, how much money some bloggers were making really shocked me. I distinctly remember one blogger telling me his website was making $30,000 per month….and this was 2009! To say this blew my mind is an understatement of epic proportions.
Investing in Index Funds – I use Vanguard for this, but there are several reputable sites out there that allow you to do the same thing.  It’s a good way to invest excess cash that you don’t need now and use it to diversify your portfolio.  I’m not going to make a specific recommendation here, but Vanguard does have a page that will make a recommendation to you based on your risk tolerance.  This is generally going to require more up-front money than Lending Club (probably $1,000+), but if you have the money, it’s something to consider.
You’re right Ed, it does require capital to get income from a rental property. However, I started hustling when I was a teen, baby-sitting, teaching younger kids the piano, doing homework with middle schoolers, being a French and Spanish tutor, none of which requires an initial investment. As do pet sitting, housekeeping, lawn mowing, house painting, and many gigs around.
Blogging is a great way to stream in income. Some consider blogging as a passive income source and they are pretty much dead wrong. It takes a lot of hard work and time to build your blog into a viable business.  It is not a good get rich quick scheme, but with time and patience you can easily earn a full time income and even exceed what you make at your full time job if you are really good.

Leveraging the internet to create, connect, and sell is something every creative person should attempt to do. The only risk is lost time and a wounded ego. You can start a site like mine for as little as $2.95 a month with Bluehost and go from there. They give you a free domain name for a year. Forget all the add-ons. Not a day goes by that I’m not grateful for my site.

Putting your money into an established franchise business could also be a great source of passive income. Seeing that this type of investment offers a built-in process, wherein and they will mostly help you out in getting started and in its inner workings – even in finding a good location for your business. This allows you to have more free time as an owner.
One thing I’ve realized is this: It’s FAR easier to work for an employer than it is to develop durable passive income streams for the average person. Why? Because working for an employer in a place that “needs” you means that it’s possible to show up and give a 50% effort. You can show up, put in your time, go home, have a beer, watch TV, and rinse and repeat all without REALLY having to put in the effort.
Industry accounts for 26% of GDP and employs 22% of the total workforce.[165] According to the World Bank, India's industrial manufacturing GDP output in 2015 was 6th largest in the world on current US dollar basis ($559 billion),[166] and 9th largest on inflation-adjusted constant 2005 US dollar basis ($197.1 billion).[167] The industrial sector underwent significant changes due to the 1991 economic reforms, which removed import restrictions, brought in foreign competition, led to the privatisation of certain government-owned public-sector industries, liberalised the foreign direct investment (FDI) regime,[168] improved infrastructure and led to an expansion in the production of fast-moving consumer goods.[169] Post-liberalisation, the Indian private sector was faced with increasing domestic and foreign competition, including the threat of cheaper Chinese imports. It has since handled the change by squeezing costs, revamping management, and relying on cheap labour and new technology. However, this has also reduced employment generation, even among smaller manufacturers who previously relied on labour-intensive processes.[170]

India's gross domestic savings in 2006–07 as a percentage of GDP stood at a high 32.8%.[206] More than half of personal savings are invested in physical assets such as land, houses, cattle, and gold.[207] The government-owned public-sector banks hold over 75% of total assets of the banking industry, with the private and foreign banks holding 18.2% and 6.5% respectively.[208] Since liberalisation, the government has approved significant banking reforms. While some of these relate to nationalised banks – such as reforms encouraging mergers, reducing government interference and increasing profitability and competitiveness – other reforms have opened the banking and insurance sectors to private and foreign companies.[209][210]
Petroleum products and chemicals are a major contributor to India's industrial GDP, and together they contribute over 34% of its export earnings. India hosts many oil refinery and petrochemical operations, including the world's largest refinery complex in Jamnagar that processes 1.24 million barrels of crude per day.[171] By volume, the Indian chemical industry was the third-largest producer in Asia, and contributed 5% of the country's GDP. India is one of the five-largest producers of agrochemicals, polymers and plastics, dyes and various organic and inorganic chemicals.[172] Despite being a large producer and exporter, India is a net importer of chemicals due to domestic demands.[173]
So one thing I have to disagree with after having done hours and hours of research from Multiple CPA’s is “Dividends – 21% (passive)”. Thats actually not right. Thats actually “active”. I actually paid 2 different CPA’s to do research on this topic. One of them I paid 500 dollars to actually dig out the IRS tax code and “prove” it. If you are active in a business and the business pays you dividends its still active income (not passive).

I’ve read stories about people setting up ad campaigns and making thousands of dollars within a matter of hours. What’s the catch?  The big one is risk.  You’re spending money to make money, so if you turn out to set up a bad ad campaign that doesn’t convert well, you can easily lose lots of money.  That’s been the primary reason I’ve stayed away from this method of making money online.  I’m not going to bother giving advice here, because as I said, this isn’t something I’ve done.  If you’re interested, you can probably find a lot of good information via Google, but watch out – as with any other internet marketing topic, most everyone is going to try to sell you something.
Purchasing a rental property is another common way that individual generate an income stream.  It is very similar to investing, in that you take a sum of money to purchase the property, and the property returns a cash flow – rent.  You do have expenses related to this that are different from investing, such as a mortgage, utilities, property taxes, etc, which all must be taken into consideration when calculating a return on rental property.
The best part is that you keep 97% of the fees paid and you don’t have to search for clients yourself . Serve them as they come. If you have a full house at some great tourist place like Goa/Shimla/Manali or those kind of places, you can put your whole house on rental basis. Many people who have a second home or extra room, hire a maid and offer the full range of services of a regular basis. Imagine if your extra room is rented even 5 times a month and you earn Rs 1,000 from it ? Its Rs 5,000 extra income !
As for me, I started focusing on passive income last year, but have owned rentals for 5 years. $25k now outside retirement accounts in mostly real estate. Looking to invest another $500k cash into real estate to get about $65k, and then 1031 under performers next year to hopefully boost that a bit higher. Heavy in real estate, but feels lower risk than the stock market to me if you have cashflowing properties. Real estate is inflation adjusted, and built in cashflow raise when the loan pays off.

There are a ton of ways to diversify your investments, some of which can send real income your way. By opening a brokerage account and investing in ETFs or mutual funds, you can earn real returns you can use to supplement your income. Of course, the flip side can also happen – as in, you can lose money. So, make sure you understand the risks before you dive in.
