Lean FIRE: The Option If You Just Can’t Wait To Escape The Grind

The FIRE movement (Financial Independence, Retire Early) works on a simple premise. Save and invest enough money and eventually, you’ll have enough that your investments can support your lifestyle. As the FIRE movement has grown and evolved over the years, different sub-categories of FIRE have been defined. I’ve written about two of my favorite types of FIRE in previous posts – Barista FIRE and Coast FIRE. Another type of FIRE – and what I’m writing about in this post – is Lean FIRE.

I often think of Lean FIRE as a bit of a shortcut to financial independence – a way to pull the plug and escape the working world sooner, rather than later. The gist of it is that if you need less money to live on, you can hit your FIRE number sooner. Lean FIRE comes with an obvious tradeoff though. If you opt for this route, you have to be okay with living on less – perhaps far less than what you might have expected.

Depending on your situation, this is a tradeoff you might be willing to make. FIRE often acts as an escape hatch for people who are unhappy with where they are in life (usually with their job). I know that’s how I felt years ago and it’s what initially drew me to the FIRE movement. 

With this in mind, I can see why Lean FIRE can be appealing to some. If you’re already a low-spender or someone who doesn’t need much to be happy, then Lean FIRE is a potential FIRE option for you. A few years ago, it could have been a path for me. But as often happens, life happens and things change.

What Is Lean FIRE – The Low Annual Spending Definition

The generally accepted definition of FIRE is that you’ve reached financial independence once you’ve saved up 25 times your annual expenses. There are a lot of studies that show that you can withdraw 4% of your portfolio annually and theoretically have it last forever. So, once you’ve saved up 25 times your annual expenses, you theoretically should earn enough from your investments that you don’t have to work again. 

The problem with FIRE is that it can take a long time to save 25 times your annual expenses. Even for the most aggressive savers, brute force saving that much can take a decade or longer. If you’re in a job that you hate, the idea of saving your way to FIRE can be daunting. And the more you need to support your lifestyle, the longer it’ll likely take you to reach your FIRE.

Lean FIRE attempts to solve this problem by dramatically reducing your annual spending. The less you need to spend each year, the faster you can reach FIRE. The tradeoff, of course, is that you have to live on less than what you might otherwise spend normally. 

There isn’t any set definition of what constitutes Lean FIRE, but it seems like most people consider it as spending less than $40,000 per year. That means for most, you’ll need to save less than $1 million. Depending on what you need, you might be able to save just $500,000 to $1 million to find yourself financially independent.

How Does Lean FIRE Work? 

Many of you reading this might already understand the numbers behind Lean FIRE, but I think it’s still worth putting here so you can get a good visual of what you need to save to reach this point. 

In general, I assume that for most people, Lean FIRE means saving less than $1 million. If you had $1 million, that would generate $40,000 per year of income. Thus, for most people, Lean FIRE probably means living on between $30,000 and $40,000. 

That means most people aiming for Lean FIRE need to save the following to generate this amount of income: 

  • $30,000 Per Year of Income = $750,000
  • $35,000 Per Year of Income = $875,000
  • $40,000 Per Year of Income = $1,000,000

Depending on your situation, you can aim to live on even less. However, realistically, most people (not all, but most) will need fairly unique situations to live on much less than the above numbers for long periods. There are people out there that are living on $500,000 portfolios. But whether that’s possible to do forever remains to be seen. 

I personally think $40,000 per year is realistic and comfortable for many to live on. Depending on where you live, you might not even have to sacrifice much. Once you get under $30,000 per year, you’re looking at living on less than $2,500 per month. That’s doable, but much more difficult if you start having to think of others in your household.

An Alternative Definition – The Basic Essentials Definition

Another definition of Lean FIRE I’ve seen (and this may be more of a sub-category of Lean FIRE, rather than an alternative definition) is that Lean FIRE means you’ve saved enough that your portfolio can cover your basic necessities. Basic necessities typically include housing, food, and transportation.

This definition of Lean FIRE is interesting because if you’re covering your necessities, you’ve set up a great foundation. The problem with this definition is that you’re still going to need some income to cover other costs. And depending on what you consider necessities, the number you have here might not be very different from your normal Lean FIRE number. 

In a lot of ways, this definition of Lean FIRE is probably closer to Barista FIRE, which is when you only need to earn a small amount each year to cover your expenses.

My Thoughts On Lean FIRE – A Good Goalpost (But Not The Ideal Endgame) 

I don’t have a problem with Lean FIRE as a concept. Indeed, for a long time, I thought I could easily live on $40,000 or less per year forever. The problem is that none of us knows what the future holds and trying to plan our lives under the assumption that it’ll always look the same is a foolish exercise, in my opinion.

That being said, I see Lean FIRE as a possibility for someone who’s single or for a family living frugally that doesn’t plan to have kids. However, if you start adding more people into your household or start having more people rely on your income, it gets increasingly difficult to live a comfortable Lean FIRE life. 

To me, Lean FIRE isn’t a good end game. Living frugally is fine and if you are truly happy living on a small amount each year, then more power to you. But for me, living frugally to get to your Lean FIRE number, only to then live frugally for the rest of your life isn’t a great goal. Money isn’t everything. But budgeting and pinching every penny in your life shouldn’t be everything either. All of us, I think, deserve more in our lives.

Still, Lean FIRE can still be a good goalpost to aim towards – another stepping stone on your way to whatever financial goal you might have. It can be a nice initial escape hatch too if you find yourself in a position where you just can’t take it anymore.

I think the best way to use Lean FIRE is to combine it with other types of FIRE. Barista FIRE, for example, is when you put yourself in a position where you only need to earn a small amount each year to cover your yearly expenses. Anyone can earn enough money to enjoy themselves a bit. Think how easy it can be to earn a few thousand dollars each year, especially if you already have your basic necessities covered.

Meanwhile, Coast FIRE is when you reach a point in your saving and investing journey where your money can grow large enough by itself to support your life at traditional retirement age. If you’ve reached this point, you can take chances without a lot of risks.

Combine Lean FIRE with Barista FIRE and Coast FIRE, you can do almost anything you want.

More Recommended Ebike/Scooters

  • Urban Arrow Ebike – Last year, I made one of the largest purchases I’ve ever made – I bought a $9,000 electric cargo bike from Urban Arrow. In my Urban Arrow review, I will discuss what it is and why I decided to buy this bike, as well as discuss how impactful a bike like this can be on your journey to financial independence.
  • Troxus Explorer Step-Thru Ebike – The Troxus Explorer Step-Thru is a fat-tire ebike that I’ve had the pleasure of riding for a while now. It has amazing power, great looks, and awesome range. If you’re looking for a great fat-tire ebike that offers a lot for the price, the Troxus Explorer Step-Thru is definitely one for you to consider. Check out my Troxus Explorer Step-Thru Review.
  • Hovsco HovBeta Ebike – The HovBeta is a folding ebike with great specs and a lot of interesting features, and importantly, it’s sold at a good price point. I’ve had a blast commuting with it and using it to do deliveries with DoorDash, Uber Eats, and Grubhub. Check out my Hovsco HovBeta Ebike Review.
  • Vanpowers Manidae Ebike – The Vanpowers Manidae is a fat tire ebike that I’ve been riding as my primary winter commuting bike and have also been using it to do food delivery with apps like DoorDash, Uber Eats, and Grubhub. After clocking in a decent number of miles with this ebike, I wanted to write a post sharing what my experience with the Vanpowers Manidae ebike has been like. Check out my Vanpowers Manidae Review.
  • Sohamo S3 Step-Thru Folding EBike Review – A Great Value Folding Ebike – The Sohamo S3 Step-Thru Folding Ebike is an entry-level folding ebike that offers a lot of value for the price point. I’ve been riding the Sohamo S3 for a while now, putting the bike through its paces, and I have to say, this bike has exceeded all of my expectations. Check out my Sohamo Review.
  • KBO Flip Ebike – The KBO Flip is an excellent bike. I’ve had a great time riding it and think it’s a versatile bike that can be used for a lot of purposes and can fit a variety of lifestyles. It’s worked out great for me as a general commuter bike and as a food delivery bike. Check out my KBO Flip Review.
  • Hiboy P7 Commuter Ebike – The Hiboy P7 is an excellent electric commuter bike that’s offered at an affordable price point. The range and speed of this bike are both very good, so you won’t have any trouble getting anywhere you need to go with it. As a food delivery vehicle, this is also good – with how much range it offers, you’ll be able to work all day on a single charge. Check out my Hiboy P7 Commuter Electric Bike Review.
  • Himiway Escape Ebike – The Himiway Escape is an interesting bike for anyone looking for a moped-style ebike. If you’re a gig economy worker, the Himiway Escape is particularly interesting and it’s possible to think of it as an investment, especially if you can opt to do deliveries with the Himiway versus using a car. It’s not cheap, but you can definitely make your money back when you compare the mileage you’ll put on your car versus using an ebike. Check out my Himiway Escape Bike Review.
  • Espin Sport Ebike – The Espin Sport is a good ebike for someone who is looking for an ebike that feels and rides more like a regular bike. There are many ebikes that are really only bikes in name. In reality, they’re basically electric mopeds. The Espin Sport, by contrast, is a bike you could probably ride without the battery and you’d feel like you’re just riding a regular bike. Check out my Espin Sport Review.
  • Varla Eagle One Scooter – The Varla Eagle One is an excellent scooter that can make sense for a lot of people. It can work as a primary mode of transportation. You can use it to work on gig economy apps like DoorDash, Uber Eats, and Grubhub. And it can also be a recreational vehicle if you’d prefer to use it for that. Check out my Varla Eagle One Review.
  • Varla Falcon Scooter – The Varla Falcon is an excellent scooter that offers a good amount of power at a lower price point compared to more powerful scooters. It’s not exactly an entry-level scooter, nor is it a high-powered scooter. I think it fits somewhere in-between those two categories – an intermediate scooter if I had to give it a category. Check out my Varla Falcon Review.
  • Hiboy S2 Scooter – The Hiboy S2 is an excellent entry-level commuter scooter that's perfect for someone looking to save some money in transportation costs and improve their commute. Check out my Hiboy S2 Review.
  • Hiboy S2R Scooter – The Hiboy S2R is one of the more interesting electric scooters I’ve been able to test out. It’s not a high-powered scooter, but for an everyday transport option, it’s very useful, especially given some of the unique features that it has. Indeed, for the price, the Hiboy S2R might be the best value scooter I’ve used. Check out my Hiboy S2R Review.
  • Fucare H3 Scooter – The Fucare H3 is a fun scooter and I’ve enjoyed testing it out. For a daily commuter or quick trips or errands, the Fucare H3 is probably the scooter I’ll use. It’s portable and easy to maneuver, so it’s just easier to take on the road when I need it. Check out my Fucare H3 Scooter Review.

    Some of the big hitters in fire seem to live a great live as a family on way less. MMM a few years ago and root of good (family of 5) puts up numbers each month and is way under $40000 per year. My family of 3 is happily under 40 per year too.

    I always get confused if FIRE numbers are for an individual, or for a couple.
    Either way if one has a paid off house, $40k/year seems like a huge amount for one, and totally doable for two. And potentially even if not a home owner depending on rent situation.
    My expenses are more like $15k a year and in 2 years when house is paid off should go down to $12k/yr (I pay small portion of mortgage which is my husband’s house)…if I stop working potentially even less since transportation is currently the largest portion of my monthly expenses.. I plan to baristaFIRE (like my works, just want more flexibility to say, go hiking for a couple months at a time). I just started saving 2.5 years ago and if you save up a huge part of your income (in my case about 75% a year) it really makes a huge difference.

    Yeah, I agree. I think you can Lean FIRE if you are single and have a $1M portfolio and can live off of $40K. For couples it would probably need to be a bit more, but I suppose it is all in the finer details of where you chose to live and how you chose to live. For families looking to give their kids well a rounded upbringing with travel, playing on sports teams, museums, etc. I think it begins to become more challenging.
