Another benefit of residual income is that, if the income stream is large enough, one does not need the main focus of his life to be on making enough money to survive. Having a comfortable and continuous level of residual income opens up more opportunities to travel, look into other business opportunities, and even take the time to indulge in his hobbies.

Under throughput analysis, the only factor that matters is the impact of a proposed investment on the ability of a business to increase its total throughput (revenue minus totally variable costs). Under this concept, the main focus is on either enhancing throughput through the bottleneck operation or in reducing operating expenses. This analysis requires a consideration of bottleneck usage by the likely mix of products to be manufactured, and their margins. This is a much more detailed analysis than is contemplated under the more simplistic residual income approach.

One of the reasons starting a blog is such a draw for people these days is the ability to generate “hands off” money. We are all longing to get out of the rat race. We want to travel, volunteer at our kids’ school, have time to do the activities we truly love instead of sitting in traffic on the way to and from work. And blogging can help make that happen.
Haha, that is too funny. I wanted to make an app back in the day called “MyShares” (You can probably tell how I cam up with the name at the time). The idea was that I would loan out books and DVD’s and then would never get them back. Then I thought, how cool would it be if I could rent those items out and that would motivate people to bring them back. Obviously, books and DVD’s are cheap, so this isn’t the money maker. The idea that would probably make the most money would be things like tools, ATVs, etc.
Nowadays, anyone can create and sell t-shirts online, even with minimal design skill and coding knowledge. You can create designs on t-shirt marketplaces that do it all for you, upload designs to print-on-demand vendors who dropship orders for you, or set up an online store and sell tees you print and ship yourself, which can be the most profitable option.

During that time I’ve met many top earners who you would think had achieved the mythical walk away income, but guess what…? They are still working today, some in their 2nd or 3rd company since I’ve known them! So where is the walk away income? I say it doesn’t exist. I have known reps who have had 100’s of thousands of distributors on their teams at one time and now they are rebuilding and doing it all over again still promoting walk away income. It makes me want to scream! They can’t see that 99.9% of the people can’t do what they do and they can’t even achieve the mythical income. – Source

Passive Income: This is the work you do for ends that will provide you with resources for the long-term. Even after you stop contributing to the effort, you are compensated again and again. Passive income is building your own empire to gain the kind of freedom we all dream about. Unlike active, it needs a bit more dedication and hard work up front, but all of which pays off in the end.

We have decided to invest in 2 ETFs, a multi asset allocation ETF (Fixed Inc, alts and div paying equities) and a preferred stock ETF. This will cover almost 45 percent of our deficit. We will be extremely diversified, can access the markets at a very low cost and the investments are liquid. On this pool of $, we have no plans to invade principal unless the investment grows by 20 percent, which we think is unlikely given the characteristics of the investments.

If you know anything well, a place, how to fix something, how to make something, how to do something, you can write a guide for it. You can sell your guide as an e-book, offer it as a download for a fee on your site or reach out to bloggers with similar content and ask if they will offer it as a paid download on their website (for a price of course).
I’ve owned several traditional brick and mortar stores in a few locations around the world and have always been a small business owner at heart. But with, I am on track to generate $1,000 per month in passive revenue through my reviews. It does take a fair amount of work up front, but once you get traffic, it converts to passive revenue pretty quickly.
Investing in rental properties: Another form of real estate investment, rental investments (i.e. becoming a landlord) could steer you down the passive income path of steady monthly rent checks that you can use to pay off a mortgage loan on the rental property. After the mortgage is paid off, those monthly checks go right into your bank account -- potentially for years to come. 
Making legitimate passive income isn’t as difficult as you might think. Some of the best passive income ideas might take a little time to set up but can start cash flowing within a couple of months and will provide a consistent monthly income for years or more. The most important point is just to get started. You make exactly $0 on the passive income sources you never start.

Plenty of online marketplaces exist to sell web design, writing, and other common skills. But one marketplace in particular, People Per Hour, allows you to sell a well defined service. For instance, if you studied interior design, you could set a fixed price to design someone’s studio apartment. The marketplace is great and allows you to be more creative with what you can offer based on your actual background.
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.
