FIRE Movement: Your Path to Financial Independence and Early Retirement

The Big Picture on Financial Independence and Retiring Early:

• • The FIRE movement is about achieving financial independence and early retirement by maximizing savings, minimizing living costs, and investing in income-generating assets like stocks and real estate.
  • Key to FIRE is a high savings rate combined with strategies to reduce spending and build passive income, allowing for financial security and freedom from a traditional career.
  • While not easy, this article explains how anyone, regardless of income, can work toward FIRE by carefully managing money, cutting unnecessary expenses, and making smart investment choices.

Who says you have to work into your 60s?

While people have been retiring early since there was work to shirk, the “FIRE movement” went mainstream in the early 2010s, popularized by Mr. Money Mustache and a few other bloggers. But does financial independence necessarily mean retiring early? How do you achieve financial freedom? And what hidden pros and cons of FIRE are you probably overlooking?

Here’s your 30,000-foot view of financial independence, early retirement, and a formula to achieve it.

Financial Independence, Early Retirement

FIRE is an acronym for financial independence/retire early, or alternately, financial independence/early retirement.

But those represent two distinct concepts. Early retirement refers to quitting your career job and never returning to the workforce—or at least not to a high-stress, high-income career.

Increasingly, some retirees blur the line and continue working a fun job either full- or part-time. Even within the FIRE movement, some proponents prefer the acronym to read “financial independence/recreational employment.”

But we’re getting ahead of ourselves.

Financial Freedom Defined

Financial independence, sometimes called financial freedom, means covering your living expenses with passive income from investments. In other words, your day job becomes optional, and you no longer need to trade time for money.

For example, say you live on $4,000 per month. You buy a rental property that generates $500/month in rental cash flow. You like seeing that extra $500/month come in, so you buy another property and then another. When you have $4,000 of rental cash flow coming in each month, you can live on the rent alone. You could quit your job in a blaze of glory if you liked.

Note that the term “financial independence” has two different meanings, depending on the context. Aside from the definition of financial freedom, it sometimes also means the ability to pay your own bills as an independent adult. Thus, 24-year-old stoner who spends his days playing video games in his parent’s basement and barely working is not financially independent.

The Path to Financial Independence

Like anything worthwhile, reaching financial freedom doesn’t happen overnight. You need to hit certain milestones to get there – think of them as checkpoints on your path to making your day job optional.

The Formula for FIRE

You get the gist: you can pay your bills and stop working with enough passive income.

But what should you invest in to reach financial independence and retire early? How much of a nest egg do you need?

Honestly, these are the easy parts of financial independence and early retirement. Easy enough that I can explain them in a few paragraphs.

The hard part is maintaining low living expenses and a high savings rate, month in and month out.

FIRE Investing: Passive income

As outlined above, you can invest in rental properties to generate passive income. And in doing so, you can bend — if not break entirely — the 4% Rule (more on that later).

But as much as we love rental income here at SparkRental, it’s far from the only passive income type. You can earn passive income streams from stock dividends, bonds, real estate crowdfunding investments, and countless other sources.

Rather than trying to pile all your money into one asset class and earn all your passive income in one way, aim to create many passive income streams. For example, I earn money from rent, stock dividends, real estate crowdfunding investments, private notes I’ve lent, and businesses I own. No one source of my income would blow your mind, but they add up.

If you’re new to investing, I recommend starting with stock investing through a robo-advisor like Acorns or SoFi Invest. It requires no skill; you can automate it and start building an investment portfolio with $10.

When you’re ready for the next step of diversification, add a real estate crowdfunding platform like Fundrise or Groundfloor. It’s equally easy and passive, with no expertise or work required.

Only consider buying your first rental property when you’re ready to learn a new set of skills and devote lots of hours to it outside of your day job.

How Much Do I Need to Reach FIRE?

As outlined above, financial independence requires covering your living expenses with passive income. It doesn’t require an exact net worth.

Still, traditional financial planners tell you to save up to 25 times your annual spending (not your annual income) because financial planners are thinking about the 4% safe withdrawal rate. Here’s how it goes: if you pull 4% out of your retirement portfolio in the year you retire, then adjust that upward each year for inflation, your net egg should last at least 30 years. Financial advisors refer to this as the 4% Rule.

But if you retire at 40, you need your nest egg to last you 40-60 years, not 30. In that case, a 3.5% withdrawal rate should keep your nest egg growing forever (see this explanation from CFP Michael Kitces for the math). Rather than multiplying your annual expenses by 25, multiply it by 28.6 to reach your target nest egg for early retirement.

Withdrawal rates only apply to stocks and bonds, not real estate investments. Real estate generates ongoing income, so there is no need to sell assets.

Actually, You Need Less Than That

Most people who reach financial independence don’t actually stop working. Oh, they may quit their high-octane career job. But there are only so many days in a row you can sip margaritas on a beach before you get bored, and fat.

Rather, most people simply switch to a new career that fulfills them. It may not pay well, but that doesn’t matter when you reach financial freedom. Some people start blogs or online businesses, such as travel blogs documenting their adventures. Others work for nonprofits, changing the world for the better. Some focus on writing novels, painting, or other artistic endeavors.

But because you won’t actually stop working, you probably won’t stop earning money. You’ll just earn less than you do today, so you don’t need to cover all your living expenses with passive income. You just need enough to bridge the gap between what you spend and how much your dream job pays.

For example, imagine you spend $70,000 per year while working a soul-sucking job. You dream of becoming a travel writer, but that only pays $55,000. You don’t need $70,000 in passive income to quit your 9-5 job — you just need $15,000 per year, to supplement the income from your dream job.

Although you may not technically be financially independent, who cares? You can still live the same post-FIRE lifestyle without meeting the full definition of financial freedom.

This is why FIREbugs like me think of the “RE” stands for recreational employment, not retiring early. It’s a mindset shift, albeit one that most people aren’t ready for when they first discover the FIRE movement.

Building Passive Income Fast

Cut your living expenses as low as possible to reach financial independence and early retirement fast. Not only does that boost your savings rate, allowing you to funnel more money into investments, but it also lowers your target passive income and nest egg. Remember, for every dollar you spend in retirement, you need $25 invested (or $28.60 if you plan to retire young)!

Automate your savings with a robo-advisor or by setting up automatic recurring transfers.

When you’re ready to expand into rental properties, read up on down payment hacks to buy a rental property with no money down. But beware of using too much leverage in real estate investing; it can leave you with negative cash flow.

You’ll be surprised how quickly your investments take on a life of their own and start generating passive income. Avoid lifestyle creep as your income rises, and keep funneling your returns and passive income back into new investments.

Honestly, that’s where the challenge of financial independence and early retirement lies: not in the math or investment strategies, but in keeping your living expenses low and your savings rate high.

Hidden Benefits of Financial Freedom Defined

The FIRE lifestyle of low living expenses and high savings comes with some surprising perks.

To begin with, recessions are less scary. As you earn more passive income, you rely less on your 9-5 job to cover your bills. If your job disappears into a recession, you can cover many of your bills with rental income, dividends, and other passive income sources.

That same lower dependence on your day job puts you in a better position to negotiate a higher salary or benefits. You can push hard because you’re less daunted by the idea of aggravating your boss. Your world wouldn’t end if you lost your job.

Those negotiated benefits could include working remotely, allowing you to move somewhere with a lower cost of living. I live in Peru, for example, which allows me to live a luxurious lifestyle on relatively few US dollars each month.

You may not need life insurance or long-term disability insurance. Low living expenses and a high savings rate mean your family could probably survive on one income if one partner shuffled off this mortal coil.

While many young adults complain that student loans prevent them from investing, living a frugal lifestyle while paying them off makes it easy to keep that “extreme savings” going. You can just funnel that money into passive income streams and retirement savings rather than student debt.

Different Flavors of FIRE

One thing that FIRE gurus don’t tell you upfront is that there’s more than one way to approach this cat. Although everyone talks about FIRE like it’s one thing, smart money folks know better.

Some people go the “Lean FIRE” route — practitioners often live around 40,000 annually (depending on location and lifestyle, but you get the idea). They embrace radical frugality, tiny homes, simple pleasures, and anything minimalistic. While this approach gets you to financial independence fastest, it’s not for everyone. 

Then there’s “Fat FIRE” – Fat FIRE followers aim for a more luxurious retirement, typically requiring $100,000+ annually. This path takes longer but allows for regular travel and fewer compromises. However, you’ll need a larger nest egg – often $2.5 million or more – but you won’t have to clip coupons or give up your morning latte.

Barista FIRE might be the sweet spot for many. It’s named after the stereotype of early retirees working part-time at Starbucks for health insurance, and this approach combines modest passive income with flexible work. You might need only $500,000-750,000 invested if you’re willing to earn $20,000-30,000 annually doing something you enjoy, but again, the numbers may vary based on individual needs and inflation.

“Coast FIRE” is another type of FIRE that’s attracting attention in recent years. It involves accumulating sufficient savings early in your career so that, without further contributions, your investments can grow to support a traditional retirement. After you hit the target number, you’ll only need to worry about your living expenses while working, and use your investments to “coast” towards your retirement goals. 

If there’s anything else to learn from these types of FIRE, it’s less about never working again and more about having the freedom to choose your path.

FIRE’S Real-World Challenges to Consider

The FIRE journey isn’t all smooth sailing. There are hurdles you’ll need to be aware of, and let me tell you – they’re not the ones most people expect.

Starting with the elephant in the room: healthcare costs. These expenses can demolish even the most carefully planned retirement budget. Without employer coverage, you’re looking at $500-1,500 monthly for a decent health insurance plan, and the price moves up the more comprehensive the package is. Some strategies to manage this include moving abroad for cheaper healthcare, having part-time work with benefits, or building a larger cushion for medical expenses. But that’s just the beginning.

Speaking of things that can wreck your plans, market volatility is another beast entirely. The 2008 financial crisis and the 2020 pandemic reminded us that markets can plummet without warning. Your $1 million portfolio might suddenly become $600,000 – right when you need it most. This is why diversification isn’t just a buzzword. Spread your investments across stocks, real estate, bonds, and even businesses. Consider keeping 2-3 years of expenses in cash during retirement to avoid selling assets in down markets.

However, the lifestyle adjustments required for FIRE are what really throw people in a loop. You might think you’re ready for the financial changes, but the social impact? That’s a whole different story. Your social circle might not understand why you’re brown-bagging lunch while they’re hitting fancy restaurants. Your family might question your sanity when you downsize your home.

Success requires clear communication, strong boundaries, and possibly finding a new community that shares your values. Trust me, I’ve seen more FIRE journeys derailed by relationship issues than market crashes.

FIRE Movement Criticisms

Haters gonna hate — and the FIRE movement has plenty of haters.

Some say it involves too much sacrifice, and people pursuing FIRE save for the future at the expense of the present. As someone who saves 65% of his household income and spends months out of the year vacationing abroad, I can tell you firsthand that’s a bogus criticism. 

The woke crowd might retort:

“Yeah but you’re a 40-year-old white male who owns an online business, you probably earn a boatload of money.”

I can assure you I do not. It took years for SparkRental to turn a profit, and even today, we reinvest most of our profits back into the business—you know, doing evil things like hiring people and creating jobs.

To this day, my family lives almost entirely on my wife’s modest teacher salary.

Some whine that only married couples can achieve financial independence and early retirement. Others claim only single people can do it, citing marital disputes over money. They can’t both be right, but they can both be wrong.

Others worry about health insurance without employer coverage. It’s good that you have so many health insurance options for early retirees.

Everyone has an excuse for not building passive income and retiring early. Most of them just don’t want to cut spending for a more frugal lifestyle — and there’s nothing wrong with that. By all means, live a normal suburban life while keeping up with the Joneses. Just don’t tell me middle-class people can’t retire at 40 because you’re wrong. Look no further than the Thompsons, who retired at 30.

FAQs about FIRE

After presenting hundreds of presentations on financial independence, I’ve noticed the same questions pop up repeatedly — and they’re good questions. Let’s discuss the biggest head-scratchers I hear.

Q: Can I still enjoy life while pursuing FIRE?

Absolutely. The key is to spend mindfully on what truly brings you joy while cutting mercilessly on everything else. Many FIRE followers report feeling more satisfied after breaking free from consumerism.

Q: What if I have kids?

Children certainly impact your FIRE timeline, but many families make it work. Consider it an opportunity to teach financial literacy early. Plus, your kids might thank you later when you can attend their school events instead of being stuck at work.

Q: Is it too late to start if I’m over 40?

While starting earlier helps, it’s never too late. You might need to adjust your target retirement age or savings rate, but the principles remain the same. Cutting just a few years off the traditional retirement age is still a win.

Q: What about inflation?

The 4% rule actually accounts for inflation through annual adjustments. However, for extra security, consider building a margin of safety by using a 3-3.5% withdrawal rate instead, especially for early retirement.

Q: Do I need to be a high earner?

Although a high income helps, FIRE is more about your savings rate than your absolute income. We’ve seen teachers, nurses, and municipal workers reach FIRE through disciplined saving and smart investing. Just live well below your means, regardless of what those means are.

Final Thoughts

Love it or hate it, the FIRE movement proves that not everyone has to work the standard 40-year career. Some work for 10-20 years, invest a high percentage of their income and then reach financial independence and early retirement.

I plan to work forever — doing things I love. That includes writing, building lifestyle businesses, and perhaps working in the wine industry.

And the more passive income I earn, the less I worry about how much I earn from active income.♦
