    What’s Your FI Number? |How to Calculate Your Number Financial Independence & Retiring Early

    To effectively achieve Financial Independence as soon as reasonably possible, you need to answer one deceptively simple question:

    What does “enough” actually mean for me?

    Once you answer that, “financial independence” is no longer just a vague idea. It then becomes two concrete dollar amounts to plan on as goal lines: the ongoing monthly income you need to cover the expenses of a comfortable life and the pot of invested money that can safely produce that monthly income for the next 50 years or more. This article is essentially a calculator in prose that will guide you through the process of calculating what your required “ FI number” of dollars is to achieve financial independence.

    You’ll also understand how that amount you need for financial independence changes in your favor if you choose to move abroad or travel full-time, thanks to geoarbitrage – earning or investing in a strong currency while spending in places where your money goes further.

    By the end of this article and the FIRE planning exercise within, you’ll have four numbers:

    1. Baseline Burn Rate – what your current life at home really costs per month and per year.
    2. Home country Financial Indpendence Number – the lump sum you’d need invested to never work again at home, in your home country
    3. Experiment Year Number – the cost of taking a one-year “test drive” of life abroad.
    4. Global FIRE Numbers – what it would cost to be financially independent in a few cheaper (or more expensive) parts of the world.

    These four numbers give you a map to “FI” to replace the hopefully mirage of early retirement that most people have.

    Two Lives, Two Numbers

    Imagine two people of the same age, career, and income.

    Person A is 38, lives in a major US city, and has internalized the headlines and social media posts that say you need $2–3 million to retire modestly, and even more ($4+ million) to retire comfortably. He accepts it because he’s unsure how else to plan so far out, but still, it feels unreachable. Unsure exactly when retirement will be (besides age 62, the social security retirement age), he treats himself to splurge opportunities to console himself, unaware of how much further down the road each pushes retirement, but unsure how much closer each hypothetical sacrifice would get him to “FI.” So he keeps working, vaguely hoping that “someday” the math will work out.

    Person B is also 38, lives in the same city, and earns the same income. But instead of accepting that retirement “might come some day” if he plays the rat race game without question, he sits down with a notebook and sketches out the most important points of an “FI” (financial independence) plan:

    • A monthly burn rate at home – understanding how many months of freedom each $1000 saved buys
    • A slightly leaner version of his expenses, covering only the essentials, for awareness of “what he actually needs to be happy” and for the start of a Lean FIRE blueprint
    • A one-year abroad “experiment” number.
    • A Home FIRE Number to stop working at home.
    • A set of Global FIRE Numbers for a life in lower-cost regions they’d genuinely enjoy.

    What seemed impossible for Person A becomes a choice between multiple paths for Person B, each with a different price tag and timeline. Same income, same reality, different awareness, achieved by “knowing your number.”

    So, how does this translate to your path to Financial Independence?

    You should ask, “What’s my number?” But a better question is:

    “What are my possible numbers across the different variations of a financially independent life that you could actually imagine and, even better, enjoy living?”

    What “Your Number” Really Is (and Why It’s Plural)

    “FIRE’ing”, or achieving financial independence and retiring early, doesn’t hinge on a single magic number, and it’s possible through more ways than one.

    Think of your FIRE “numbers” as three doorways into FIRE with your burn rate being the foundation:

    1. Your Baseline Burn Rate (Routine Expenses): This monthly or yearly expense is what it takes to keep the lights on, keep you fed and housed, and keep life feeling normal where you live now—monthly and annually. All of your “FIRE” and “Escape” numbers are built and calculated based on this initial number.
    2. Your Home FIRE Number: A single amount of money (sometimes called your “FU” number) that, if invested, would produce enough income to cover your baseline burn rate without needing to work, for decades or for life.
    3. Your “Experiment Year Number”: The cost of spending a year abroad, slowly testing 6–12 destinations that you’re curious about, or simply want to experience. Not a fantasy gap year, but a realistic, well-budgeted experiment.
    4. Your Global FIRE Number(s): The different amounts of money that, if invested, would cover your burn rate if you lived permanently in lower-cost countries or regions, using cost-of-living differences to your advantage.

    Why these numbers matter

    These numbers turn the dreamy idea of FI into a specific goal.
    Vague dreams are hard to plan around.

    By knowing your numbers, “I want to retire early” becomes “I need $1,000,000 to do it in Eugene, Oregon, and $500,000 to do it in Sardinia or Bangkok.”

    These numbers are decision-making tools.
    Knowing your numbers lets you decide, with clear trade-offs, when to:

    • Stay in your current job to continue accruing assets and staying on track
    • Negotiate for remote work to ease into an Expat FIRE or Nomad FIRE situation
    • Take a sabbatical to test FIRE life as you get closer to FI and the dream becomes more realistic
    • Move abroad to accelerate your path, potentially settling in a more cost-efficient locale, to transition or test while still employed.
    • Give in to that purchase, or skip it, knowing how much closer it brings you to early retirement.

    Your FIRE numbers act as stress filters.
    A huge amount of money anxiety comes from not knowing if you’re “behind.” But, “behind” according to what? If you don’t know where you want to be, or need to be, it’s impossible to know.

    If you know your target and where you stand, you can choose when to push harder, when to coast, and when you’re actually on track.

    Your FIRE numbers are lifestyle design guidelines tailored to your wants and needs.

    Your numbers force you to confront what you truly want from life – comfort vs simplicity, roots vs mobility – and what you’re willing to trade to get there. Then, it challenges you to build a life around the discoveries of what you need.

    Let’s build those numbers step by step.

    Step 1: Find Your “Burn Rate” for Normal Life

    Before we talk about FIRE numbers and life abroad, we need one foundational piece: what your current life actually costs. Essentially, you “burn rate.”

    Your burn rate is the amount of money it takes to live your current life comfortably. Your housing, food, utilities, transport, basic fun, and the ordinary frictions of living where you live all add up to your total monthly or annual expenses and your burn rate.

    How to quickly calculate your burn rate:

    1. Gather 3–6 months of your spending data: Collect your checking account and credit card statements for the last three to six months.
    2. Calculate your average spending per period: Add all of your purchases and expenses across that period.
    3. Subtract unusual, large, one-off expenses and purchases: Go through those statements and subtract big, unusual expenses such as cross-country wedding trips, once-a-decade dental work, or the blow-out vacation you know you won’t repeat every year. This leaves your true, basic expenses for your normal life.
    4. Divide and annualize for monthly and yearly burn rate: Take the adjusted total and divide by the number of months gathered for your states to find your average monthly burn rate. Then, multiply that by 12 to find your annual burn rate.

    What you have now is your baseline burn rate: what it costs to live your preferred lifestyle, in your current city, living roughly how you live now.

    A concrete example: My life in Dallas

    Before I left Dallas, Texas, in 2017 to travel the world, I did this exercise of figuring out my personal burn rate. I discovered the following:

    Six months of checking and card statements showed $24,000 of total spending.

    Within the six months of expenses, I had:

    • A wedding trip to Florida that cost ~$1,000
    • A vacation to Rocky Mountain National Park that cost ~$1,000
    • A few weeks hosting my niece and nephew, that cost ~$1,000 for bowling, Chipotle, ice cream, and plenty of little bits of fun.

    Those one-off items totaled $3,000. Subtracting them from my initial calculated expenses of $24,000 left $21,000 in typical expenses for me over six months.

    From there:

    $21,000 ÷ 6 months = $3,500 as my monthly burn rate.

    $3,500 × 12 months = $42,000 as my annual burn rate.

    So, at that point in my life

    I had a monthly burn rate of $3,500, and I had an annual burn rate of $42,000.

    These are the numbers I used as my baseline in calculating my own FIRE numbers and my “geoarbitraged” cost of living around the world.

    Now, do this same for yourself to calculate your burn rate (and the basis for your FIRE numbers). Write down your monthly and annual burn rate. We’ll come back to your burn rate repeatedly, so keep the number handy.

    Step 2: Find your “Experimental Year Abroad Number”, which is the cost of a year abroad for you

    Now we’ll calculate something different but equally powerful for those interested in a life abroad: the cost of a one-year experiment to live abroad and sample the world.

    Think of this as the number that buys you a 12-month test drive of life in other locations around the world. In this potential experience, you not only get a sampling of different countries, cultures, and lifestyles, while you figure out where you’d actually want to land you also experiment with how geoarbitrage can accelerate your savings and push you to financial independence sooner.

    Within this experience, and the number behind it, we’ll plan on a one-year life spent with 1 to 2 months in each country on your list of places you would love to live, moving to the next new location every 1 to 2 months.

    We’ll call this your Experiment Year Number.

    Click here if you simply want to jump to Step 3 and calculate your FIRE number only for staying in your home country, but I highly recommend keeping an open mind and exploring the idea of a year abroad.

    How to calculate the cost of a one-year experiment abroad

    1. List 6–12 places you’d like to live for a month each: These can be countries or specific cities: Portugal, Mexico, Chiang Mai, Buenos Aires, Lisbon, Da Nang, Medellín, etc. Feel free to review this list of great countries for residencies and this list of countries by cost of living to spark some ideas.
    2. Use a cost-of-living database for roughly accurate cost of living data: Go to a site like Numbeo or Expatistan and look up the monthly cost of living for each place (a country or specific city is fine). Then, use the estimated monthly cost for a family of four as a proxy for what your monthly cost of living will be as a single “nomad” on your year abroad. That number tends to be higher than what a solo nomad or couple will actually spend, which we want, as it builds some financial padding into the budget.
    3. Add up the research monthly costs of living for each of your destinations across the year you have in mind: This total of estimated COL across destinations for a year gives you a rough total cost of living for a year spent living in all of your chosen locations.
    4. Add one “big flight” in and out: Use Google Flights to price two one-way tickets between your home and the furthest point on your route. Round up a bit.
    5. Add a budget for regional flights to move between your locations throughout the year: A good, simple assumption for travel is one short-haul or intra-region move per month via a regional or budget airline that will cost around $250 per flight. To account for the year of wandering, multiply 12 months × $250 per flight = $3,000. If you have an urge to be adventurous (think, flying from Istanbul to Mongolia) throughout the year, feel free to look up actual flights for a more accurate budget.
    6. Optionally add:
      • A rough number for travel insurance ($50 to $200 per month, depending on your age and the quality of the insurance)
      • Any big, intentional “splurge” experiences: Getting a race car driving license, attending a sushi making intensive in Japan, taking a luxurious trek to Everest Base Camp, etc.
      • A small buffer for things you inevitably didn’t think of: Perhaps, $100 extra per month as a 7 Eleven budget in Japan or an “emergency kebab” budget in Berlin.
    7. Calculate the total for the experimental year abroad: Add these all together, and you have your Experiment Year Number – what it would cost, with a reasonable margin for error, to spend a year living, wandering, exploring, and tasting a life abroad.

    An example: my first year abroad

    Before I left the US in 2017, I put this into practice. I brainstormed a 12-country bucket list designed around experiences I felt like I was missing:

    • Thailand: Beach bungalows, reading, and pad Thai.
    • Vietnam: Motorbiking the Ho Chi Minh Trail and exploring its history.
    • Nepal: Trekking to Everest Base Camp.
    • Sri Lanka: Learning to surf and seeing wild elephants.
    • Ecuador: Visiting the Galápagos Islands and testing an expat-friendly country for a life abroad.
    • Colombia: Dancing, food, and adventure.
    • Chile: Trekking Patagonia and wine.
    • Argentina: More Patagonia, more wine.
    • Portugal: Port wine, seafood, old-world architecture, walkable neighborhoods, and a rising nomad hub.
    • Greece: Volunteering, Mount Olympus, and the Aegean.
    • Turkey: Experiencing where “west meets east” and deep history beyond the media’s perspective.
    • Jordan: Experiencing one of the most welcoming countries in the Middle East.

    Using Numbeo’s “family of four” estimates, at the time, the monthly costs came out roughly as:

    • Thailand: $2,211
    • Vietnam: $1,546
    • Nepal: $1,194
    • Sri Lanka: $1,863
    • Ecuador: $1,888
    • Colombia: $1,986
    • Chile: $2,389
    • Argentina: $2,541
    • Portugal: $2,804
    • Greece: $3,177
    • Turkey: $2,378
    • Jordan: $2,460

    Adding those 12 monthly estimates gave a total of $26,437. That’s the rough cost of living for a year, split across those destinations, and a geoarbitraged burn rate of about $2,203 per month on average.

    To that, I added:

    • A “big flight” budget of $2,200 in and out (two long-haul one-way flights from Bangkok to Dallas at about $1,100 each).
    • A year of shorter flights at $3,000 (12 months × $250 intra-region flights).

    The individual totals came out to:

    • $26,437: Cost of living around the world (if I stayed put)
    • $2,200: Major flights (if I decided to go home once a year)
    • $3,000: Regional flights (if I decided to keep moving)

    This added up to…

    $31,637 for my total Experiment Year Number.

    Notably, that was less than my $42,000 annual burn rate to live in Dallas.

    Could I have done it for cheaper? Almost certainly. In practice, long-term stays and the local knowledge we accrue with longer stays usually push costs down. But using family-of-four figures and rounding up built in a healthy safety margin to my budget and “Experiment Year Number”.

    Now, run this same process for your own “dream year” (or a smaller 6-month experiment). That number becomes your price of trying on another life without committing to it forever.

    Step 3: Calculate Your FIRE Number (for your home country)

    Now that you know what your current life costs (burn rate), and what a one-year experiment abroad might cost (Experiment Year Number), we can talk about FIRE numbers. These FIRE numbers are the lump sums, properly invested to produce ongoing returns, that could safely pay enough and allow cash withdrawals to support spending levels equal to your burn rate for the rest of your early retirement and financial independence.

    The key concept here is the “safe withdrawal rate”.

    The safe withdrawal lens (“4% rule” of thumb)

    Decades of research on retirement portfolios, most famously the Trinity Study and work by financial planner Bill Bengen, suggest that a diversified portfolio of stocks and bonds can usually sustain a 4% annual withdrawal (calculated as 4% of your invested assets), with payment withdrawals increasing with inflation, over long periods without running out of money in most historical scenarios.

    In FIRE circles, this is often simplified to the “4% rule”:

    If you can live on 4% of your invested assets each year, then you likely have “enough” to be financially independent.

    For planning purposes, though, it’s useful to think in terms of a range: 3% is a very conservative Safe Withdrawal Rate, often for very early retirement or those wanting extra safety. Alternatively, 4% annual withdrawal rate is still conservative by historical standards for many people, assuming a long horizon and a well-diversified portfolio.

    These withdrawal rates can be mathematically simplified as follows:

    • 4% withdrawal ≈ 25× annual spending (since 1 ÷ 0.04 = 25), and is estimated to last for 50+ years
    • 3.5% withdrawal ≈ 29× annual spending.
    • 3% withdrawal ≈ 33× annual spending.

    To keep things simple and conservative, we’ll use 25× as the default multiplier, knowing that you can adjust it up if you want a more conservative calculation and more margin for error.

    From “burn rate” number to “Home FIRE” Number

    Using my Dallas example:

    My annual burn rate at home was $42,000.

    Using the 25× rule of thumb, my Home FIRE Number = $42,000 × 25 = $1,050,000.

    This means that with $1,050,000 invested in a well-diversified way, I could withdraw $42,000 per year (or $3,333 per month) for the rest of my life.

    Let’s check the math.

    4% of $1,050,000 = $42,000.

    On paper, that portfolio of $1,050,000 could support my Dallas lifestyle indefinitely, without additional work, in most historical scenarios.

    Now, do the same with your own annual burn rate.

    Your Home FIRE Number ≈ annual burn rate × 25

    That’s the approximate price tag of financial independence if you never move and always spend about what you do now.

    Step 4: Calculate your “FIRE Abroad” number

    We can apply the same math of the “25x rule” to the Experiment Year Number to get the approximate cost of your life abroad.

    From earlier:

    We learned that the cost of my experimental year abroad came to $31,637.

    If we multiply by 25, then we find myNomad FIRE Number” = $31,637 × 25 ≈ $790,925.

    So, $790,925 is the rough amount I’d need to invest, at a 4% withdrawal rate, to indefinitely fund a lifestyle abroad similar to my experimental year.

    This “nomadic lifestyle” would include:

    • Living in a rotating set of global destinations
    • Taking one or two long-haul flights per year
    • One shorter move per month on average

    Comparing the two scenarios of FIRE at home and FIRE abroad, we have:

    • My Home FIRE Number (Dallas): $1,050,000
    • My Travel FIRE Number (nomadic): $790,925

    In my rough scenario, it is over $250,000 cheaper to be financially independent as a world traveler than to be financially independent staying put in Dallas.

    As an expat and nomad who has actually lived abroad for the last ~10 years, I assure you, this savings estimate is accurate, and at worst, a conservative estimate of how much cheaper FIRE abroad has been for me.

    Your own math will differ, but the principle stands:

    Changing where you plan to live can change how much you need to reach FIRE—in some cases, dramatically.

    Step 5: Understand How Geoarbitrage Changes the Amount You Need to Retire

    So far, we’ve compared two points, which is FIRE for life at home (Dallas, in my case) vs. a specific nomadic year I designed.

    Now we’ll generalize that idea with geoarbitrage, which we’ll define as choosing to live in places where the cost of a good life is lower than the same life would cost at home, without compromising on safety or quality.

    Using cost-of-living multipliers to see how much cheaper life is in a different country or city

    Cost-of-living databases like Numbeo and Expatistan don’t just give raw costs; they also allow us to compare the cost of living in one city or country to another.

    For example, Expatistan’s data suggested:

    • Bangkok’s cost of living was about 58% of Dallas’ cost of living
    • Thailand overall was around 39% of the US average

    Using those as rough multipliers, and starting from my Dallas annual burn rate of $42,000, we can estimate the following about the cost of living in Thailand:

    Bangkok life is 58% the cost of Dallas:

    • $42,000 per year in Dallas × 58% ≈ $24,360 per year in Bangkok
    • My Global FIRE Number (in Bangkok): $24,360 × 25 ≈ $609,000 to live abroad in Bangkok, indefinitely

    Life in the Rest of Thailand is 39% the average cost of living in the US:

    • $42,000 × 39% ≈ $16,380 per year
    • My Global FIRE Number (in Bangkok): $16,380 × 25 ≈ $409,500 to elsewhere in Thailand, indefinitely

    Compared to my Home FIRE Number in Dallas ($1,050,000), those price tags of $609,000 and $409,000 are very different for financial independence.

    Destination tiers as a starting point

    You don’t need precise numbers for every country to see the pattern. You can think in rough tiers, based on older Expatistan comparisons (your actual planning should always use fresh data):

    Around 30–40% of US costs

    Examples: Vietnam (~29%), Ecuador (~31%), Georgia (~32%), Thailand (~39%), Indonesia (~39%), Malaysia (~39%).

    Around 40–60% of US costs

    Examples: Mexico (~49%), Colombia (~49%), Brazil (~43%), Costa Rica (~62%), Greece (~62%), Panama (~62%).

    Around 60–80% of US costs

    Examples: Portugal (~60%), Spain (~61%), Finland (~61%), Germany (~73%), Italy (~74%), France (~76%).

    Close to or above US costs.

    Examples: Netherlands, Ireland, Canada (~88%), Australia (~86%), UAE (~87%)—often “roughly equal” or higher in major cities.

    These are broad brushstrokes, not precise quotes, but the primary point remains. If your annual burn rate at home is $40,000, and you move somewhere at 50% of US costs, your local annual burn rate will likely be closer to $20,000.

    At a 4% withdrawal rate, your FIRE number drops from about $1,000,000 to about $500,000.

    How to apply this to your own life

    1. Pick 3–5 countries or cities you’d seriously consider living in.
    2. Check a fresh cost-of-living comparison between your current city and those places using Expatistan or Numbeo.
    3. For each destination: Multiply your current annual burn rate by that destination’s cost-of-living percentage to get your local burn rate. Then, multiply your local burn rate by 25 to get your Global FIRE Number for that destination.

    Do this for a few places, and you’ll see your potential FIRE numbers fan out into a range of options, many of which may even be possible now, instead of a single daunting figure.

    Step 6: Build Your Personal “Number Map”

    At this point, you’ve gathered enough pieces to build a simple but powerful number map regarding your financial independence options.

    To make your personalized financial independence number map, write down:

    1. Baseline Burn Rate
      • Monthly: $_____
      • Annual: $_____
    2. Experiment Year Number
      • Total cost for a one-year abroad test: $_____

    Your Experimental Year Destinations and Monthly Costs

      • Country 1:_____________ & Monthly Cost _____________
      • Country 2:_____________ & Monthly Cost _____________
      • Country 3:_____________ & Monthly Cost _____________
      • Country 4:_____________ & Monthly Cost _____________
      • Country 5:_____________ & Monthly Cost _____________
      • Country 6:_____________ & Monthly Cost _____________
      • Country 7:_____________ & Monthly Cost _____________
      • Country 8:_____________ & Monthly Cost _____________
      • Country 9:_____________ & Monthly Cost _____________
      • Country 10:____________ & Monthly Cost _____________
      • Country 11:____________ & Monthly Cost _____________
      • Country 12:____________ & Monthly Cost _____________
    1. Home FIRE Number
      • Annual burn rate × 25 = $_____
    2. Global FIRE Numbers
      • Country/City A: ________ local annual burn rate $_____ → FIRE Number $_____
      • Country/City B: ________ local annual burn rate $_____ → FIRE Number $_____
      • Country/City C: ________ local annual burn rate $_____ → FIRE Number $_____

    You now have:

    • A clear view of what it costs to be you right now (your burn rate)
    • A price tag for trying on another life for a year (Experiment Year Abroad Number)
    • A rough estimate of what it would cost to retire early at home (FIRE Number)
    • Several alternative price tags for retiring early in other parts of the world (Global FIRE Number(s))

    Instead of one impossible-sounding number, you have multiple paths, each with its own cost and flavor.

    Step 7: Plan for Uncertainty, Risk, and Safety Margins

    All of this math is useful, but it’s still a road map we’re laying over a messy reality, and with that trail blazing mindset, it’s only prudent to acknowledge the risks and uncertainty, and plan for them accordingly.

    There are three big sources of uncertainty we need to acknowledge, be aware of, and plan for.

    1. Sequence of returns risk

    This is the risk that markets may do poorly in the first years after you stop working and start drawing from your investments. If you’re withdrawing during a bear market, you’re selling more shares at lower prices, which can hurt long-term sustainability and quickly shorten your timeline to FI even with the same withdrawal rate.

    How do we mitigate risk from sequence of returns:

    • Use more conservative withdrawal rates (closer to 3–3.5%) if you’re very early in retirement or risk-averse.
    • Keep a larger cash or bond buffer (e.g., 1–3 years of expenses) so that you don’t have to sell equities during down markets, and can delay your stock sales without delaying withdrawals.
    • Maintain some flexibility in your lifestyle to reduce spending or earn a bit of income if markets hit a rough patch.

    2. Inflation and currency risk

    As a nomad or expat “FIRE’ing” in our home country currency (US dollars or Euros) with bonds and equities purchased in our home countries, the movement of currency in our home country relative to the country we choose to live in is very important.

    If your investments and spending are in different currencies, or if you move to a country with higher inflation, the real value of your withdrawals can change, and you need to be aware of this possibility, its effects, and how to navigate around it long term.

    How we mitigate risks from currency movements:

    • Choose destinations with relatively stable inflation for the long term, as shown historically in their economy
    • Be familiar with the average currency exchange rate range for your country, to avoid dips, and stock up on local currency when rates spike
    • Be willing to adjust destinations over time if costs rise faster than expected.

    3. Life changes

    Your life won’t stand still after you reach a number. Kids growing through phases and needs, aging parents, health issues, and new priorities can all reshape what “enough” means and where life as you need it is possible.

    How to plan for inevitable life changes (and dance with them):

    • Treat your FIRE numbers as directional, not sacred, and be honest about your changing needs that change your numbers.
    • Heavily consider family and children, and the phases they’ll pass through, along with the needs those phases bring, when calculating FIRE numbers and considering destination countries and cities.
    • Revisit your numbers every few years, or whenever something major changes, reassessing for new costs of living, inflation, and life changes.
    • Consider buffers as a margin of error, including planning a bigger emergency fund, maintaining part-time work or the option of it, maintaining flexibility in your destination choice (mentally, logistically, and financially), and hiring professional planning help when you’re close to executing (financial planners, immigration attorneys, and fixers in your country of choice).

    The key mindset to maintain is that your number is a range and an adaptive plan, not a single figure carved in stone. Additionally, it’s better to be approximately right, keep moving, and refine as you go than to wait for perfect precision and never start.

    Step 7: Understand Where to Go from Here

    If you’ve followed along, you now have:

    • Your Baseline Burn Rate at home.
    • An Experiment Year Number for trying life abroad.
    • A Home FIRE Number.
    • A handful of Global FIRE Numbers for places you might like to live.

    That’s more clarity than most people ever get.

    From here, a practical next move could look like this:

    1. Track your spending for the next 1–3 months to refine your burn rate.
    2. Rough out a real one-year abroad plan, even if you don’t plan to execute it yet.
    3. Attempt to narrow down to 1 or 2 long-term scenarios you find genuinely attractive:
      • Stay home and aim for Traditional or Fat FIRE**.
      • Build toward ExpatFIRE in a specific country.
      • Pursue LeanFIRE** or NomadFIRE with a travel circuit.
      • Use BaristaFIRE or Coast FIRE** to buy back time earlier, then simultaneously create your life abroad.
    4. Run the numbers for each scenario and ask:
      • Which path feels most alive to me?
      • Which path is most realistic given my income, skills, and tolerance for uncertainty?
      • Where do I want to aim first, knowing you can pivot later?

    Now that you know your numbers, you’re no longer just vaguely “saving for retirement.” You’re actively working toward specific lives you’ve imagined and feel passionate about – lives at home, abroad, and somewhere in between.

    The rest of your FIRE journey is about choosing which life you want to step into, temporarily or permanently, and then building the financial and logistical runway to get there.
