Although precise data are not available, the total household wealth in the world, excluding human capital, has been estimated at $125 trillion (US$125×1012) in year 2000.[37] Including human capital, the United Nations estimated it in 2008 to be $118 trillion in the United States alone.[6][7] According to the Kuznet's Hypothesis, inequality of wealth and income increases during the early phases of economic development, stabilizes and then becomes more equitable.

Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.
1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.
You need to decide which machines you want to run, get the necessary licenses to operate them (you're selling items so you need to get sales licenses and whatnot from your state), buy the machines and a truck for the items in the machines, find a supplier of the products, and then finally you can secure locations. Finally, you need to service them periodically or hire someone to service them.
First off, I’m a blogger so it seems wrong not to mention it, but more importantly, it’s a legitimate way to make money. It’s quite possibly the least straight-forward way on this list, but it’s very doable and it’s also quite possibly the funnest way on this list. I love blogging and I know hundreds of bloggers who feel the same. So let’s talk about making money blogging and what it really means.
Write pitches. If you have located a client for whom you want to write, send pitches, which are topic ideas for articles. Write pitches that not only show your expertise, but also demonstrate your enthusiasm for the topic.[21] First, read the publication to which you are sending pitches to familiarize yourself with what they publish. If applicable, identify a specific section and send our pitch to the appropriate editor. Also, include a brief summary of who you are.[22]
The wealth of households amounts to US$280 trillion (2017). According to the eighth edition of the Global Wealth Report, in the year to mid-2017, total global wealth rose at a rate of 6.4%, the fastest pace since 2012 and reached US$280 trillion, a gain of US$16.7 trillion. This reflected widespread gains in equity markets matched by similar rises in non-financial assets, which moved above the pre-crisis year 2007's level for the first time this year. Wealth growth also outpaced population growth, so that global mean wealth per adult grew by 4.9% and reached a new record high of US$56,540 per adult. Tim Harford has asserted that a small child has greater wealth than the 2 billion poorest people in the world combined, since a small child has no debt.[23]
You’re right though that $50 per month probably won’t be sufficient in perpetuity. The numbers in this article serve as a baseline for what I need to survive. This is how much I’ll need to quit my job and live the life I plan on living immediately after FI. If 5 years after FI I decide that I really want to live in America full time again, I’ll have to increase my health insurance budget by either decreasing some of my other costs or by earning more money through part-time work that I enjoy. The main message of this post is that you don’t necessarily have to wait until every possible future expense is covered…just make sure you can survive in a lifestyle you want to live and then if you need to earn more money to change or enhance that lifestyle, you can do so. A lot of people think, oh I need $2.5 million to retire so that every possible expense that I could incur will be covered. That may be true for someone retiring in their 70s but for someone in their 30s, I say, cover your essentials, start living a free life as soon as possible, and earn more if you want to change your lifestyle later.
I am a small animal vet in the Washington DC area. Vet school loans and housing have taken their toll. I would like to retire at 60 (I just turned 52), and reach budget or baseline. Blockbuster isn’t a reality. Choose your career well– I love what I do, but sometimes wish it paid more. Semi-retirement may also be an option. Thank you, Sam, for a great post (as always).

Your freedom grows alongside your savings. Eventually, you will have enough money saved to feel comfortable switching jobs, starting a business, returning to school, traveling for a year, or any number of other activities that are impossible to achieve without savings. This stage of financial freedom might include major life changes, but they are not permanent. Your freedom is temporary because your savings will be depleted over time, forcing you to find other sources of income again.

We set up a business and personal budget for ourselves and include savings goals. Then to keep ourselves accountable we review our budget monthly. This keeps us on track to reaching our financial goals. I'd recommend setting up a system that works best for you and your family. Just writing down your goals will help you start the process. But, reviewing them daily and having honest conversations about where you are financially will determine your success or failure in becoming financially free.
Categories. Identify what’s truly necessary by identifying all of your monthly expenses based on the past six months, and then divide your expenses into three categories: Essentials, Nonessentials, and Junk. Write down every expense (food, housing, utilities, insurance, cars, gas, transportation, clothes, credit cards, phones, Internet, pets, entertainment, etc.); triple-check the list with your significant other or a friend; and then use your Essentials, Nonessentials, and Junk categories to prioritize and cut wherever you can. The stricter you are, the sooner you’ll be free.
To me the biggest reason for not quitting my job before have close to $10M is the cost of raising kids. I don’t see how it will work out for folks retiring at 35 with $1M saved if they plan to raise a family. Providing a good life, after school activities, travel opportunities, college, etc. I assume I’ll spend at least $1M per child to raise them from birth through college. (The average is ~$250,000 to get them just through high school and that doesn’t include many of the things I hope to do as a family)
Since I am so close, I won’t ask for more money or be aggressive because I don’t to jeopardize my retirement at 55. Losing 31K less pension plus 8K for medical is a total loss of 39K passive income. It takes $975,000 at 4% to generate 39K. With a better pension of 70K instead of 39K means that both pensions of 132K (70K+52K) will more than cover expenses. Then we can stop buying munis and that 2M of principle can be used to buy a decent place in Hawaii if we choose to. Wife said NO to buying so I have to work on her.
The figures are very optimistic! Even though I technically could “retire” with only $200K saved up, I’m going to continue working until 2015 and should have quite a bit more than that, when all’s said and done. I just wanted to compute the minimum amount it would take to cover my essential expenses to see how little I would actually need to survive. You’re definitely right that it’s a great feeling seeing how attainable FI really is!
I retired at age 56 with budget/baseline FI, but I am now in blockbuster category (age 69). My investment accounts have done well and the house has increased in market value. Renting part of the home covers housing and transportation expenses, and my small pension covers basic living expenses. I withdraw money from investments for travel but reinvest most of the gains. I too am faced with heavy income taxes once I have to withdraw from tax deferred accounts. I have run spreadsheet projections for income, net worth, and income taxes to 2035 with various withdrawal plans and estimated net returns. Always come back to deferring tax as long as possible, spending down the taxable accounts first, while building up the tax-free account agressively. What I would do differently is learn to invest my own money at a younger age, buy a bigger better house at a younger age, and retire earlier.
