The idea of financial independence retire early (FIRE) has gained tremendous steam over the past few years. FIRE is a movement where people seek to save money, invest, and grow their wealth so that they can retire much earlier than is typical. Pursuers of FIRE also tend to spend less than most, focusing on increasing their income, reducing expenses, and investing the difference whether it be in real estate, stocks, bonds, etc.
But, while many people dream of early retirement, some dream even bigger with Fat FIRE.
Fat FIRE allows you to live large in retirement and requires more money invested than regular FIRE.
FatFIRE will require you to accumulate millions and may not be achievable for the average person, but it is only one of the types of FIRE one can pursue to make early retirement a reality.
If you’re a high-income earner or seek a higher standard of living in your golden years, read on to explore the benefits of Fat FIRE and see if this lifestyle is right for you.
What Is Fat FIRE?
Fat FIRE turns the concept of financial independence retire early up a few extra notches. Those pursuing Fat FIRE strive to not only reach financial independence but to retire early with enough wealth to support a higher standard of living and more discretionary spending in retirement.
In general, Fat FIRE is defined as having enough money to spend at least $100,000 a year in retirement comfortably. Using the standard 4% rule, this level of annual spending would require a Fat FIRE number of around $2.5 million in investments.
Although Fat FIRE requires significantly more money invested and is harder to achieve, it appeals to many because it allows you to enjoy your retirement lifestyle without sacrificing luxuries. You will also have more wiggle room for unforeseen events.
Types of FIRE
Fat FIRE allows you to sustain an upper-middle-class lifestyle in early retirement, but it isn’t the only path to retiring early. The FIRE movement covers a spectrum of options, and the amount of money you’ll need to achieve financial independence varies with each.
Let’s take a look at the most common types of FIRE.
The FIRE movement began with the idea that if you have 25 times your anticipated annual expenses in investments, you could utilize a safe withdrawal rate of 4% and have enough money to last at least 30 years.
For example, if you need $50,000 a year to live on in retirement, you would need $1,250,000 invested.
Lean FIRE is for those who are comfortable living a frugal lifestyle. Generally, those pursuing Lean FIRE live on $40,000 a year or less with a safe withdrawal rate of 4%.
Using the 25x rule, someone pursuing Lean FIRE living on $30,000 a year would only need to save $750,000 to retire early.
Barista FIRE is a bit different in that you don’t need more money saved to achieve it. With Barista FIRE, all you can work part-time to cover your expenses. The name came from the idea of working part-time at a coffee shop, but others may choose to work gig economy jobs or freelance. Many choose a part-time job that grants access to healthcare, saving thousands in out-of-pocket costs.
Coast FIRE is when you’ve saved and invested enough money to have enough to retire at the traditional retirement age even if you never contribute a penny again. These individuals usually start investing early and have a higher annual income. Their savings rate is also typically high. As a result, they have built a large nest egg and a healthy net worth at a younger age.
The difference with this version of FIRE is that the individual still plans to work until the traditional retirement age to let their investments compound. Rather than retire early, they choose to stop investing and enjoy their life along the way, all while allowing what they have invested in to grow.
Then we have Fat FIRE, where an individual seeks to cover expenses of $100,000 or more a year in retirement. Again, typically someone pursuing Fat FIRE makes a healthy amount of money and likely has a high net worth. However, it is harder for the average individual to achieve Fat FIRE due to the higher Fat FIRE number one must attain, which must be at least $2,500,000 invested.
Pros and Cons of Fat FIRE
Like anything, there are pros and cons to pursuing FatFIRE.
- Enjoy a more luxurious lifestyle in retirement
- Have more ability to give
- Have more of a buffer for setbacks or unforeseen events
- Have financial flexibility
- It may take longer to achieve
- You’ll need to save much more money
- It can lead to lifestyle inflation
- It will be difficult for those without a high income
Calculating Your Fat FIRE Number
Regular FIRE assumes you’ll need roughly 25x your anticipated annual spending invested in the stock market and/or other areas. You can use the same formula to calculate your Fat FIRE number – the trick will be to estimate how much you’ll be spending accurately.
One way to go about calculating your FIRE number is to estimate your spending in all areas in as much detail as you can, then multiply that number by 25. Since Fat FIRE will typically allow you more financial flexibility, another way to go about it is to pick an annual spending threshold and calculate your FIRE number based on that. The key will be to ensure you don’t exceed that threshold once you retire, or you may need to find a source of supplemental income.
For example, you could choose $100,000 as your desired annual spending. With that in mind, your Fat FIRE number would be $100,000 x 25 = $2,500,000.
Alternatively, if you estimate that you’ll need to spend $125,000 a year, then your number would be $125,000 x 25 = $3,125,000.
One important thing to note is that achieving Fat FIRE isn’t just about how much you save, but how fast you can save it. Your savings rate (how much of your income you save) is the number one factor in FIREing more quickly. The more you save, the more time your money will have to grow.
You’ll also need to consider things like your current net worth, income, health, and inflation rate and how they will impact your future cost.

How to Get to Fat FIRE
As mentioned, your savings rate will be the most significant factor in reaching FIRE and when. To be considered Fat FIRE, you’ll need to have saved and invested AT LEAST $2,500,000, which is a daunting amount. The key will be to make and invest as much cash as possible until you have reached that threshold.
While the numbers are pretty straightforward, the path you choose to get to Fat FIRE can look however you want. For example, you could live an extremely frugal life during the pursuit to save faster, or you could select more balance and have a slower journey.
Your ability to Fat FIRE will also depend on your choices once you’ve reached it. Those willing to live in a lower cost of living areas who have far fewer living expenses will be able to live a more luxurious life than those in more expensive places like San Francisco, Seattle, and New York. If you own your primary residence and have little or no debt, you’ll also be able to make your money go further.
While a lofty goal, usually Fat FIRE, takes more time and money to achieve, it simply won’t be realistic for everyone. However, there are many paths to early retirement, and it is possible to live a great life on much less than a six-figure investment income.
Who Is Fat FIREing?
Most who can achieve Fat FIRE are entrepreneurs and other high-income professionals, but that isn’t always the case. Given enough time and consistent investing and the average Joe could also achieve the net worth required to Fat FIRE.
