Managing Editor The FIRE movement aims for something that traditional retirement planning doesn’t – leaving full-time work long before the typical retirement age of your 60s and 70s, with enough money invested to last the rest of your life.
Short for “Financial Independence, Retire Early,” there isn’t a strict formula for reaching FIRE, but the path to it can be demanding. Most personal finance advice recommends saving 10%-15% of your income toward retirement, but the most committed FIRE adherents aim for 60%-70%.
“It's basically having the financial flexibility to have the ultimate life flexibility,” says Rachael Burns, a certified financial planner at True Worth Financial Planning, a financial planning firm based in Granite Bay, California.
However, following FIRE can leave very little to live on now, and isn’t a strategy for everyone. But there are various forms of FIRE, depending on whether the goal is leaving the workforce entirely, semi-retiring or just buying the freedom to walk away from a job you don't love. Here’s how to make FIRE work for you.

What are the different types of FIRE?
The FIRE movement can be reduced down to its simplest form – spend nothing, live frugally, invest aggressively – but there are various forms of FIRE, and each one can be further personalized.
- Lean FIRE: The most minimalist approach for people who can live off very little and save more than half their income to achieve financial independence faster.
- Fat FIRE: For people who want to maintain a higher lifestyle in retirement. Supporting a $200,000-a-year lifestyle, for example, requires far more saved than living on $50,000.
- Barista FIRE: The semi-retired approach, where you save enough to partially cover your retirement expenses but continue to work. For many, the appeal is more meaningful work or access to benefits like health insurance.
- Coast FIRE: This approach focuses on saving and investing aggressively early in your career until your balance reaches a point where it can compound to your FIRE number on its own. From there, you can keep working full-time without further retirement contributions, freeing up your income for current spending or other priorities.

Whichever version of FIRE you’re aiming for, the underlying blueprint is similar. Here’s some of the steps that followers of FIRE often consider when nailing down a strategy:
Rule of 25
The rule of 25 says you need to save 25 times your annual expenses to retire. To get this number, first multiply your monthly expenses by 12 to figure out your annual expenses. Then multiply that annual expense by 25 to get your FIRE number.
So, for example, if your monthly expenses are $6,000, you multiply that by 12 to get an annual expense of $72,000. Multiply that by 25 and you’ll have your FIRE number of $1.8 million.
If a FIRE number seems too ambitious, some people explore ways to increase their income and then invest that extra money.
The 4% rule
The 4% rule says that retirees can withdraw 4% of their savings the first year and then adjust that number for inflation in future years to avoid running out of money in retirement. The 4% rule assumes a 30-year retirement goal, so if you plan to retire earlier than that, it may not be accurate for you.
Burns says investors should be cautious about following advice designed for the masses, especially when it comes to determining a FIRE number.
“I see a lot of people saying, ‘Oh, you need to have this much money and then you can retire,’ or ‘You can safely withdraw 4.5%.’ These rules of thumb are really big generalizations, but like any of that financial advice, it's never one size fits all,” Burns says.
The right savings rate
If you’re interested in early retirement, think about how much money you plan to save and invest annually to reach your goal.
“Figure out a savings rate that matches the speed at which you want to go,” says Paris Woods, author of “The Black Girl's Guide to Financial Freedom” and a FIRE supporter.
If your goal is to achieve financial independence in 10 years or less, Woods suggests saving about 70% of your income.

The magic of compound growth
Due to inflation, cash saved in a bank account – even a high-yield savings account – might not be enough to sustain you for the next 40 years. However, investing in tax-advantaged retirement accounts, such as IRAs and 401(k)s, can do more, thanks to compound interest, capital gains and dividend reinvestment.
Both IRAs and 401(k)s have annual contribution limits, though. So what happens if you’ve maxed out all of your retirement accounts? Where do you save and invest next?
“Invest as much money as you want in a regular brokerage investing account,” Burns says. “There's no limit to how much you can add to that.”
What you invest in — stocks, bonds, or funds such as ETFs — depends on your risk tolerance. “It does need to be invested fairly aggressively, and aggressive means something different to everyone,” she says.
FIRE also requires you to stay invested, even in times of market turmoil, Burns says.
"FIRE is a long-term strategy, and you can't be too reactive to short-term economic events. You may need to adjust spending or saving in certain years based on market events, but the underlying strategy should stay the same."
Tax-efficient strategies
A question you should ask yourself when devising a strategy is how much money you’ll need between your goal retirement age and the age you can start withdrawing from your retirement accounts penalty-free, which is usually around 59½.
Once you have that number, you could consider saving that amount in your regular brokerage account. While you do have to pay taxes on any taxable event in your brokerage account – dividends and interest earnings, for example, as well as capital gains from selling investments –, you can avoid the extra early withdrawal penalty associated with unqualified withdrawals from your retirement account.
“There's no way to get around paying taxes — it’s just part of the game, and if you're paying taxes, it probably means you're making money. So it's kind of a good thing.”
Many FIRE adherents also look to the Roth IRA when planning out tax-efficient strategies. That's because not only does the Roth IRA allow for tax-free withdrawals in retirement, but some funds are also accessible after five years. This can be done through a backdoor Roth, which is a transfer from a traditional IRA to a Roth IRA, or through a mega backdoor Roth, which is a transfer from a 401(k) plan to a Roth IRA. When conversions are done over consecutive years, this is called a Roth conversion ladder.
Limitations of FIRE
Retiring early might sound appealing, but it’s not for everyone. Consider the downsides:
- Achieving FIRE requires getting strict with your spending, which is not always doable. It can mean sacrificing vacations, meals out, discretionary purchases and more.
- If you stop working, you’ll have to foot your own medical expenses until Medicare kicks in around age 65. You’d need to make sure costs like that are built into your plan.
- Your investments may not perform as well as you thought. That could become something that sends you back into the workforce.
If you don’t earn enough to cover your basic needs and save aggressively for early retirement at the same time, FIRE may not be for you, Burns says. Lacking an emergency fund or owing high-interest debt are other reasons that FIRE might not be attainable.
If someone's making minimum wage, FIRE is not going to be doable for them, Burns says. But if they make enough to live comfortably on half their income and invest the rest, that's how you get started.
