This means that you can either jump start your passive income by investing some money in it from the start - such as paid advertisement or something of that sort, or spend a sizeable amount of time perfecting yourself and working around what you’ve got without having to spend any money. Passive income generating is by no means an easy task, and will definitely take some action to reach, but it is very, very reachable.
What if the manager of the Idaho investment center wants to invest $100,000 in new equipment that will generate a return of $16,000 per year? This would provide residual income of $4,000, which is the amount by which it exceeds the minimum 12% rate of return threshold. This would be acceptable to management, since the focus is on generating an incremental amount of cash.
Typically, the above formula will be applied such that the company is assumed to achieve maturity, or "constant growth". (Note that the value will remain identical: the adjustment is a "telescoping" device). Here, analysts commonly employ the Perpetuity Growth Model to calculate the corresponding terminal value[3] (although various, more formal approaches are also applied[4]). Then, assuming long-run, "constant", growth {\displaystyle g} from year {\displaystyle m} , the terminal value is
Keep in mind that most passive income business ideas usually become largely profitable after a certain amount of time, depending on the time and money you put in. It is important to know that some, also, never make it and fail - just like any other business in the world. However, some passive income businesses are more vulnerable and others are less risky and more prone to giving a good payout at the end of the month.
This was by far my biggest return on investment. It took about two weeks to figure out how to format my book for paperback and get setup for Createspace, but this is nearly 70% of my revenue. It’s ironic because my e-book is $4.99 and my paperback is $14.99. I priced the paperback higher because I wanted to drive readers to the ebook, where I could update it more easily. What I learned, however, is that many of the people buying my book are parents, not students, and they are more familiar with paperbacks. There is also an incorrect perception that you need a Kindle to read Kindle ebooks.
The topic of buying and selling blogs deserves it’s own book though and is a very difficult skill to master I must say.  I rant about the greatness and simultaneous pitfalls of marketplaces like Flippa elsewhere on this site, but needless to say I think this is it’s own expertise; worth learning more about for a lot of us who know that starting a business (getting momentum) is a lot tougher than fixing up and steering an existing business to greater profits (maintaining and directing momentum).
Buy a small business: A local small business, like a car wash or a laundromat, is a great way to put money down on a money-making venture. Automate it so you don't have to be on the premises unless you're collecting money. Go into a local business with your eyes wide open - study the books, especially on income and expenses, and examine water and utility bills if your venture will be open 24 hours.
There are so many great resources today at our fingertips to learn about the world of investing, business, and finance such as blogs, podcasts, and online courses. However, I feel the most tried and true method is still by reading good ol’ fashioned books. I’ve collectively spent a few hundred dollars to purchase these books, but I can tell you that they have resulted in countless dollars in savings and millions in current and future earnings. There really is no better return on investment.
I have a system in place to make sure it doesn’t happen. I have my wife who is helping us stay grounded and making sure my head doesn’t grow too big. But I also say to my audience, Hey, If you see me becoming somebody different from who you know I am or who I’m supposed to be, then catch me before I get off track. I’m not about buying a huge mansion, or really fancy cars. I’m more about the family and making it comfortable at home and going on family trips and creating memories.
Similar to what Chris Guthrie did with his Amazon niche sites back in 2008-09, you should take every dollar you earn and reinvest it into your passive income business…pay for more content to be created, for better (and quality) backlinks to be built, to buy new niche sites etc.  At least for the first few years.  Chris did this, and it allowed him to go from $0 to $100,000 in just over 12 months.
