What Is Lean FIRE? My Real $1,800/Month Life in Vietnam

Lean FIRE is early retirement on a deliberately small budget, usually $20,000 to $40,000 a year for one person. Instead of building a huge portfolio to bankroll a big lifestyle, you keep your expenses low enough that a much smaller portfolio can carry you for life. Save up roughly 25 times your annual spending and you are there.

That is the textbook answer, and I am going to give you the lived in one. I actually do this, on $1,800 a month in Vietnam, with a $540,000 Lean FIRE number, for a life that does not feel lean at all. Below is the real definition, the exact math, and an honest look at where every single dollar goes, including the full contrast with the $6,000 a month I used to burn in New York.

The Life I Left: $6,000 a Month in New York

Before the beach and the slow mornings, there was New York. I spent a year and a half at Meta doing endless and high effort work that I knew would never make anyone's life better, and here is what it cost me just to exist while I did it.

That came to $72,000 a year, about ₹68 lakh, simply to live a normal and comfortable life. No penthouse and no Michelin dinners, just New York's baseline price of admission. Even while saving half of my tech salary, I was still lighting $72,000 on fire every year for a lifestyle that was slowly burning me out.

The Shift: I Went the Other Way

In January 2025 I cold quit and got on a plane with no real plan at all. The obvious move for a burnt out Indian in New York is to fly home to Pune and regroup, and I did the complete opposite. I explored Southeast Asia first, Thailand and then Vietnam, and I ended up in Da Nang, a coastal city with real beaches, fast internet, and a genuinely buzzing community of expats and digital nomads.

I did not leave in order to retire. Once I saw how little a genuinely good life costs over here though, I ran my numbers close to 100 times and realised I could simply stop grinding for a bigger pile. So I restructured my entire life around something much smaller and much calmer.

My Actual Numbers From Last Year

I sat down and pulled every transaction from my past year of living in Vietnam. These are not estimates, they are the actual numbers.

$1,800 a month, or $21,600 a year.

At a 4% withdrawal rate that works out to a Lean FIRE number of $540,000, which is roughly ₹5.1 crore. Half a million dollars for a real and full life, with good food, a nice apartment, international travel, and enough left over to support the people I care about.

The Honest Asterisk: $1,100 Core vs $1,800 All In

Here is the part that most "I live on $X abroad" posts quietly skip. My $1,100 a month is my pure core cost of living, and my true all in number is closer to $1,800, and I will not pretend otherwise. My bare essentials in Da Nang look like this.

Call it about $1,100 a month, roughly ₹1 lakh, for the essentials, which is $13,200 a year against New York's $72,000 for a genuinely better daily life. The gap up to $1,800 is the stuff that is not really about living in Da Nang:

• The personal trainer, around $240, which is a luxury rather than a necessity
• Visa runs, around $100 a month averaged, which is the Vietnam tax on an Indian passport
• Flights home and family support, around $460, since I fly back to India and I send money to people I love

Add all of that on top and you land at about $1,800 a month. So when you plan your own version of this life, plan on the all in number and never the shiny headline one.

The Spending Breakdown, Line by Line

Let me walk through the real budget piece by piece, because the honest detail is far more useful than generic advice.

Housing, $375 a month

I rent a 1 bedroom apartment in Da Nang that sits steps from the beach, and it is nothing like a shoebox. It has a full kitchen, air conditioning, 100 Mbps internet, a balcony with an ocean breeze, and 24 hour security. In most major US cities $375 is roughly one week of rent, and in Manhattan this same place runs well past $3,000. One honest caveat is that apartments here are genuinely hit or miss, so I spent two weeks viewing places before I signed anything. Most tourists pay $600 to $900 for the same square footage because they search in the obvious tourist strips, so do the legwork and look in a local neighbourhood instead.

Food, $600 a month

This is my biggest expense and I do not feel even slightly deprived on it. I eat out for most meals and I eat really well. A banh mi is a dollar or two, a proper bowl of pho is $1.50, and a sit down meal with a drink is $5 to $8, while fresh produce from the morning market costs almost nothing. The real unlock here is that eating healthy is the default rather than a daily act of discipline, which is the reverse of how it felt in New York. The one thing that is genuinely expensive is imported whey and supplements, and that is a small price to pay.

Gym and trainer, $20 plus a coach

The gym itself is $20 a month. Then I added the one thing I could never justify in Manhattan, a personal trainer 3 times a week at $19 a session, which comes to roughly $240 a month. In New York that was over $100 a session, so I simply never did it, and I am in the best shape of my life now for what amounts to a rounding error on my budget.

Scooter and gas, $75 a month

I rent a scooter for around $50 and spend about $25 on gas. It replaces the $150 a month I used to hand over for the subway and Ubers, and I can get anywhere in the city in 10 minutes.

Healthcare, cheaper than you would guess

The cost that scares most people off is healthcare, and day to day it is a genuine non issue here. Da Nang has Vinmec, a JCI accredited international hospital, along with a stack of international clinics. A doctor visit runs a few dollars and out of pocket costs are a fraction of US prices. For anything serious I carry international health insurance, which unlike the $370 a month I bled on insurance in New York actually feels like a rounding error. It sits outside my $1,100 core simply because it is cheap enough that it barely moves the needle.

Visa, $100 a month

This is the one line that is purely a Vietnam specific overhead. Every 3 months I renew my visa, and it costs roughly $300 to $400 per renewal, which averages out to about $100 a month. I walk through the whole thing in the Vietnam visa process for Indians. It is the Vietnam tax, it is predictable, and it is still cheaper than what I used to spend just commuting in a US city.

Travel and family support, around $725 a month

This is the most personal category and the one that swings the most from month to month. I fly back to India to see family a couple of times a year, I take weekend trips around Southeast Asia when the price is right, and I send money home when it is needed. Some of this is discretionary travel and some of it is support for people I love, and I include all of it because it is real. Your own Lean FIRE number should include the things that actually matter to you and not only your bare survival costs.

Where to Live in Da Nang, and Where I Work

Da Nang splits into two worlds and both have their own charm, the beachside east of the Han River and the riverside along the downtown waterfront. I am a beach person, so here is the lay of the land.

• An Thuong is the expat and digital nomad hub, walkable and packed with cafes and bars and restaurants, a 2 minute scooter from My Khe beach. If you are new to the city, start here.
• My An sits right next door, a touch calmer and still beachside.
• Son Tra is the peninsula and my personal favourite, green and quiet and genuinely stunning, with monkeys in the hills and a winding road up to Ban Co peak. It is so calm that Bill Gates reportedly picked it for a Vietnam holiday, at around $30,000 a night in villas at the InterContinental Sun Peninsula, and I live minutes away for $375 a month.

When it comes to work, the cafe scene here is unreal. I rotate between The Hideout in An Thuong, where the coconut coffee is the move, and Lighthouse over on the Son Tra side, which roasts its own beans. When I need to properly lock in, I book a desk at Enouvo Space, the main coworking spot in town.

Cheap Does Not Mean Rundown

People hear $1,100 a month and picture something shabby, and Da Nang is the opposite of that, a city on a steep rise. Robert De Niro's Nobu brand is building its first residences in all of Southeast Asia right on My Khe beach, handing over in 2027, and global money is pouring in. I am not part of any of that. I just live a 10 minute scooter ride from all of it, on a fraction of what I once spent merely to survive in New York. That is the quiet magic of this place, where the luxury and the affordability sit side by side and you get to pick your own slice.

What Lean FIRE Annual Expenses Actually Are

The standard definition is that Lean FIRE is early retirement on annual expenses of $20,000 to $40,000 a year. You reduce the lifestyle enough that a much smaller portfolio can sustain it. For a single person that usually lands between $1,500 and $3,300 a month, and my own $1,800 sits in the lower middle of that range. You will sometimes see this same idea called Skinny FIRE, which is simply another name for the same strategy.

If you are Indian and weighing this route specifically, I wrote a full breakdown of retiring in Southeast Asia as an Indian, covering real costs in Vietnam and Thailand, how it compares to Pune, and the visa reality on an Indian passport.

Where you land in that range comes down to 4 things rather than your coffee habit:

1. Housing, which is the biggest lever by far
2. Healthcare, which is punishing in the US and cheap or free in much of the world
3. Location, since domestic versus international geo arbitrage changes everything
4. Food culture, because places with vibrant street food cost a fraction of supermarkets

My $1,800 a month Vietnam life sits at the bold row, at $540,000 needed at 4% and $664,000 at the safer 3.25% rate.

What Is the Lean FIRE Number?

Your Lean FIRE number is your annual expenses divided by your withdrawal rate. At 4% that is the same as multiplying your annual spend by 25, and at a more conservative 3.25% you multiply by roughly 31. Mine works out to $21,600 times 25, which is $540,000 at 4%, or about $669,600 at 3.25% if I want more cushion against sequence risk.

The reason this matters so much is geography. Look at the same me in two different cities.

• In New York my annual expenses ran $72,000, about ₹68 lakh, for a FIRE number of $1.8 million, roughly ₹17 crore.
• In Da Nang my all in expenses run about $21,600, about ₹20 lakh, for a FIRE number of $540,000, roughly ₹5.1 crore.

Same person, same 4% rule, and a target that is smaller by well over a million dollars. Geo arbitrage bought my freedom years earlier than staying in New York ever could, and location is the single biggest lever on the whole FIRE path. If your own portfolio is closer to $500,000, I ran every strategy for retiring at 35 with $500k, where geography rather than the raw amount decides whether it works.

Why might you want the more conservative number? Because Lean FIRE portfolios have almost no fat to trim during a crash. A Fat FIRE retiree who loses 40% of a $3 million portfolio trims the travel budget, while a Lean FIRE retiree who loses 40% of $600,000 trims food, and that difference is very real. For a proper stress test of your withdrawal plan, the Sequence Risk Calculator shows how different market timing scenarios hit a lean portfolio.

What You Are Giving Up (Honest)

I said I am making some sacrifices, so let me name them plainly.

A permanent home base is the first one. I do not own property and I do not hold a lease longer than 3 months. For some people that would feel unmooring, and for me right now it genuinely does not, though I will not pretend it suits everyone.

Distance from family and friends is real. The timezone gap to India means calls happen at awkward hours, and I miss things, weddings and festivals and ordinary Tuesday dinners, and no amount of cheap banh mi fully makes up for that.

Visa uncertainty is another one. Vietnam has no simple permanent residency path for someone like me, so I am always one policy change away from needing to relocate, and I keep a contingency plan in the back of my mind for it.

US healthcare is a genuine long term question mark. If I ever needed to return to the States for an extended stretch, my healthcare costs would balloon instantly, and my international insurance covers emergencies rather than a full move back.

Stepping off the income escalator has a cost too. If I ever want to climb back on, the gap on my resume will matter, and I have made my peace with that.

What Vietnam Gives Back

Now the other side of the ledger, because Vietnam gives back in ways that are hard to put a price on.

Time is the one that hits you first. I write when I want to write, I do not set an alarm, and I take a long walk at 10am on a Tuesday because that is when the light is good.

The quality of food is the next. I eat better here on $600 a month than I did on $700 a month in New York, with fresh vegetables from the morning market and food cooked in front of me and no drive through anything, and my health has measurably improved.

Community surprised me most. There is a large expat and digital nomad crowd here, and I have met founders and writers and investors and retirees from every country, so the social life is genuinely rich.

Then there is the weather, since I can go outside in January, and the pace, because afternoons slow down and coffee is taken seriously and nobody is sprinting to their next meeting. After years of sprint culture that has been deeply restorative.

New York, by contrast, was never just expensive in dollars. It cost me time in hour long commutes, it cost me stress through the noise and the crowds and the permanent hum of the hustle, and it cost me my health through less sleep and more takeout and a gym too pricey to actually use. Da Nang handed all of that back, and you cannot put a clean dollar figure on it, though it mattered more than the $6,000 ever did.

Pick Your Battles

Here is the mental model I keep returning to, which is simply to pick your battles. I gave up a permanent home base and I kept world class food. I gave up convenience and I kept my time. I gave up career progression and I kept the freedom to decide what every single day looks like.

You do not have to make the same trades I did, because Lean FIRE is a framework rather than one fixed lifestyle. The real question is which constraints bother you least and which freedoms matter most. For me, I do not care much about driving a nice car and I care enormously about controlling my own calendar, so trading expensive infrastructure for time freedom is a deal I will take every time. The people who struggle with Lean FIRE are usually the ones who have not worked out which battles are worth picking, so they give up things they actually care about and keep things they never needed, and that is when it starts to feel like deprivation. When you trade the right things, it stops feeling like a sacrifice and starts feeling like the deal you always wanted.

Is This Sustainable Long Term?

The question I get most is whether anyone can really live like this forever. The honest answer is that I do not know, and I do not need to, because the whole beauty of geo arbitrage is optionality. I can move back to the US, try another country, or raise my budget whenever I choose.

Here is how I actually fund it. I do not sell investments to pay for my life. I keep a cash buffer parked in high yield savings and short term CDs and I draw from that, which lets the portfolio compound untouched, and I walk through that entire structure in my three bucket approach. Because my spend is a fraction of what it once was, that buffer stretches for years. The point was never to live on $1,100 forever, the point is that I can.

Final Thoughts

I am not telling you to move to Vietnam. Geo arbitrage looks different for everyone, whether that is San Francisco to Austin, London to Lisbon, or New York to Da Nang. The principle underneath it all is the same everywhere, which is to cut your cost of living without cutting your quality of life. For me, going from $6,000 to a real all in $1,800 was the whole unlock, and it bought freedom and health and time. Location is the biggest lever on the FIRE path and most people never once touch it.

When you are ready to work out your own target, run the math with our guide to calculating your FIRE number, and if the numbers feel impossibly far away today, remember that I started from $40,000 of debt and got here inside a decade, which I walk through in going from $40k debt to Lean FIRE at 33. And if you are still weighing whether this life would genuinely suit you, I wrote a full guide on whether Lean FIRE is right for you.

Frequently Asked Questions

What is the typical Lean FIRE annual spending amount?

For a single person in the US, Lean FIRE annual expenses typically run $20,000 to $40,000 a year. Internationally, especially in Southeast Asia and parts of Latin America and Eastern Europe, you can run a full lifestyle on $18,000 to $25,000 a year. My actual spend in Vietnam was $21,600 a year.

What does Lean FIRE mean?

Lean FIRE means Financial Independence, Retire Early on a minimal but intentional budget, typically $20,000 to $40,000 a year for a single person. It needs a much smaller portfolio than traditional FIRE, because you keep annual expenses low through geographic arbitrage, housing choices, or both.

Can you really live on $1,100 a month in Vietnam?

Yes, and $1,100 a month covers a comfortable core lifestyle in Da Nang, with a modern beachside apartment, eating out most meals, a gym, and a scooter. Plan realistically on closer to $1,800 a month all in once you add visa costs, flights home, and anything you send to family.

Is Lean FIRE the same as Skinny FIRE?

Basically yes. Skinny FIRE is just another name for Lean FIRE, early retirement funded by a small portfolio and a lean budget of roughly $18,000 to $40,000 a year for one person. Some people reserve Skinny FIRE for the very leanest end of that range, and in practice the two terms describe the same strategy.

How do you calculate your Lean FIRE number?

Divide your annual expenses by your target withdrawal rate. At 4% you multiply annual expenses by 25, and at a safer 3.25% you multiply by 31. My own math is $21,600 a year times 25, which is $540,000 at 4%, or $669,600 at 3.25%.

Can I do Lean FIRE in the US without moving abroad?

Yes, and the specific lever is housing. Cities like Tulsa, Columbus, Tucson, and much of the rural South and Midwest have cost structures where $25,000 to $35,000 a year is genuinely liveable. Going international simply accelerates the math a lot faster.

Is Lean FIRE deprivation?

Only if you trade away things that actually matter to you. I gave up a permanent home and geographic stability, which I do not particularly need right now, and I kept great food, full control of my time, and community. That is a trade I made with my eyes wide open.
