Also, I feel like engineers are much more likely to be attracted the FIRE mentality and tend to have the incomes and low spending habits that can get them retired easily by their mid 30s. I'm personally in that boat, and frankly, I'm a little bored but not bored enough to go back to work as an SE full time. If companies offered more part time work and highly flexible work, it might be enough to drag me back in. Even large six figure salaries just aren't enough money for the soul crushing reality of renting out my brain full time to solving someone else's problems now that I have enough.

"that can get them retired easily by their mid 30s" Maybe a small subset. The median dev salary is $110k. So no, only a very small number are able to retire in their 30s.

  The absolute value of your salary doesn't tell you anything about how long it takes to get to retirement (or more accurately, financial independence). That's exclusively a function of your spending and saving rates. https://www.mrmoneymustache.com/2012/01/13/the-shockingly-simple-math-behind-early-retirement/ https://www.mrmoneymustache.com/2012/01/13/the-shockingly-si...
  - dnissley 5y ago
    The absolute value of your salary does highly correlate with cost of living, unfortunately. Which may have an effect on your savings rate.
    - anonporridge 5y ago
      Yes it does. If you have a high salary, you are probably living in a HCOL area. If you have a low salary for the same kind of work, then you are probably living in a LCOL area. The savings rates of these different individuals could be the same if the salary difference is proportional to the cost of living difference.
      - lolinder 5y ago
        But 20% of $200k/yr is $40k/yr, while 20% of $100k/yr is $20k/yr. If you make twice as much while saving the same rate (i.e. cost of living goes up proportionally), you'll still end up saving twice as fast. Then move to a LCOL area, and you've got twice as much saved as the people who've lived there all their lives.
        p1necone 5y ago
        Yep - this is what a lot of people who suggest moving to a cheaper area as a solution for not being able to buy a house don't seem to think about. Earning (made up numbers because I don't even live in the USA and I don't know what is reasonable) $100k and spending half of it on rent with no hope of buying a house is still better than earning $50k in an area with much cheaper housing. Of course if you can score a remote job then you can have the best of both worlds, but that isn't always possible (and some companies seem to pay differently based on your COL now).
        kelnos 5y ago
        I think it's a pretty big unsourced assumption that savings rates are similar between LCOL and HCOL areas. I'm curious if that's really true; I wonder if there's any research/polling done on this.

        Even if the saving rates are the same, the higher salary in a higher COL wins because you can always move before retirement. However, today’s high inflation rates make all these computations iffy, and if you rely too much on inflation beating stock market returns, you won’t be able to ratchet down on risk as you get closer to your preferred early retirement date (a crash can dump you back in the workforce at a bad time). Also, many people in HCOLs don’t want to downgrade to LCOLs after they retire. Too bad Medicare doesn’t transfer to low cost but nice southeast Asian countries.

        I am in the same mindset. I take deep satisfaction that I have something substantial to leave to my kids. I don't want to spend it on me. I don't like to travel, and I don't like "stuff." I have a few hobbies but they are not expensive.

I vaguely remember reading a surprising number of posts from HNW people that regretted not trying certain hobbies / activities when they were young enough fully enjoy them. That saying that no one on their deathbed says their biggest regret is that they didn't work harder, is probably a trope for a reason.
    - giantg2 5y ago
      There's also the fact that most people have to spend. Build your own house? Grow your on food? Most people are buying those.
    - anonporridge 5y ago
      Never said it's easy. But spending much below your means is the only reasonable path to financial independence and wealth. I for one don't want to live in a society that exclusively prioritizes now and doesn't sacrifice anything to plan for the future. "A society grows great when old men plant trees in whose shade they know they shall never sit."

    Salary is the absolute ceiling for savings rate, so I'd say it's a big factor.

      - giantg2 5y ago
        Yes I did. Your comment indicates that you don't understand ceiling. The article is overly simplistic in regards to things like cost of living, inflation, and returns on the savings. Do you really think you can save 90% of your income and retire after 3 years? This is terrible financial advice and completely ignores functions and changes in spending due to life events. Not to mention, I don't believe that function is legitimate depending on retirement age and current age combinations.
        robotresearcher 5y ago
        > Do you really think you can save 90% of your income and retire after 3 years? You certainly can if you make 5 million a year! Which means that absolute income is absolutely relevant.
        kelnos 5y ago
        Hell, in many places you can retire under those conditions if you "only" make $500k a year. The trick is to move to a much lower cost-of-living area after you retire, often abroad. If that kind of thing floats your boat, anyway.
        88913527 5y ago
        If your income is $100k and you save $90k, spending $10k, after 3 years, you will have saved $270k. With growth, you might have $300k. To support your ongoing $10k annual expenses, you'd only be spending 3% of your portfolio. The math checks out. Of course with taxes, a savings rate of 90% is more than likely to be possible.
  - tharkun__ 5y ago
    I don't think that is accurate. I would say it is a combination of both. The article you link to obviously makes it sound like it's an exclusive function. But it simply dismisses the fact that not everyone can reasonably sustain the savings rates mentioned. Sure, there's reports of very motivated people that live on next to nothing and have a huge savings rate for the first 10 years of their working life, abstaining from everything including having a family and such. For the vast majority of people this is not something they can achieve and that is not taken into account by the 'simple math'. I would agree with the author that having Starbucks coffee twice a day is not worth retiring later. I'd even give him Cable TV. But I'm not going to live like a hermit. Different people are on different places of this gradient. If I increase my take home pay, I can stay on the same savings rate as before and retire earlier (assuming that I don't want to make a certain percentage of my last pay during retirement and instead have a fixed goal for my retirement income).
    - anonporridge 5y ago
      We all have to make the choice between prioritizing creature comforts and freedom. I chose freedom. While my colleagues were living in fancy high rise apartments, buying new gaming rigs and cars, taking extravagant international vacations, and getting married and having kids, I was living in a basement studio with my college mattress on the floor and no car for several years while biking to work. I'm retired and they're still slaving away with no end in sight. No risk and sacrifice, no reward.
      - leeoniya 5y ago
        > getting married and having kids i have not met anyone yet who is married with kids but would have preferred an earlier retirement instead. kids are more expensive than all the other things combined that you listed - no amount of living in the basement or saving 30k on having no car is going to make up for that.

It's probably not _only_ inflation, supply and demand will have caused the majority of this shift, since savers saw their money start evaporating. But that is of itself of course a second order effect of inflation, so I think the point stands.
        UncleMeat 5y ago
        Sure, but the only kind of inflation that really crushes people living off their investments is stagflation, where increasing prices of goods is not reflected in portfolio sizes. If your investments are growing way faster than the price of goods, there is no problem.
    - kelnos 5y ago
      Not sure I agree. Trinity study suggests that if you retire 30 years before death, you can safely withdraw 4% every year during retirement, regardless of economic fluctuations. If you retire super early and need 50 or 60 years, your safe withdrawal rate is probably closer to 3% or even 2%, though. Your point may be that we should expect significant economic turmoil in the near- and medium-term, much more than "fluctuations", which may be true, or may not be. Impossible to predict the future. Consider that the 2021 inflation rate is likely a symptom of COVID. Monthly inflation rates for the last few months of 2021 were trending downward. Hopefully we can expect inflation to get back to something approaching normal by the end of 2022. Even if it takes a couple more years, there's no reason to expect that 7% inflation is the norm going forward. (Also consider that people who are doing FIRE certainly don't have much in treasuries. It's going to be mostly in stocks. That certainly carries other risks, of course.)

    Forecasting your spending rate far enough into the future, however, is a very tricky problem if you're trying to retire at 30, especially if you're living through turbulent times. I'd rather work 3 days a week until I'm dead then let my skills start deteriorating now and live the next 60 years in fear that my fixed income won't be able to sustain me.
    - wiz21c 5y ago
      spot on. Energy prices are going to rise in Europe for the years ahead so will inflation and then your savings will dwindle... In my country inflation is already around 2.5% years on years.

      As someone who's been working for +10 years now for 3 day's a week I can say: spot on! I've got savings enough for fun projects or holiday's, and my 3 day job simply pays the rent/gas/electricity bills.

      When you forecast your spending rate, you naturally take some security margin, for example by retiring when your passive earnings gets 1.5x times larger than your targeted spending. And that security margin (which won't be spend most years) will compound. Sure, you might encounter a black swan event which force you out of retirement only 3 years after you started, and at that point your security margin won't have increased your stash by much, but at the same time your skill won't have deteriorated much in 3 years. It also work even if the black swan even happens 20 years after your retirement. You just need to take a security margin your are comfortable with, and project how much you will have after 3, 10, 25 years to see how much you have for unforeseen events.
- MichaelDickens 5y ago
  On $110K income, you could: - Pay roughly $30K in taxes - Spend $30K, which is close to the median American's individual expenditure - Invest the remaining $50K At that rate, you can achieve lean FIRE in 15-20 years. So not quite mid-30s, but not far off. Of course, in a high cost of living area, you might need to spend more than $30K, but you'd also make more than $110K. (For what it's worth, I lived in SF for several years and spent less than $30K annually.)

  But, this small subset is what company urges to have. If they are willing to lower down the baseline, there are still quite many engineers around the world.
lhorie 5y ago
I haven't really seen a whole lot of evidence that there's any stronger correlation between FIRE and engineers compared to other jobs (in fact, many FIRE blogs are from non-eng people). And conversely, there's plenty of engineers who have kids (hence, very much not FIRE). The vast majority end up going down that route, in fact, at least in my experience.
- loeg 5y ago
  Why do you say kids are incompatible with FIRE? They add some expense, but it is not insurmountable with a high income like many senior software engineers enjoy. There are prominent FIRE folks with kids -- e.g., "Mr. Money Mustache."
  - lhorie 5y ago
    I wouldn't go as far as say they're incompatible; I'm sure it's doable. But there's a pretty big difference in believability between the claim that "engineers are much more likely to be FIRE people, to the extent it makes a noticeable difference in the engineering job market, now of all times" vs "FIRE people w/ kids exist, but are outliers among outliers"
    - loeg 5y ago
      Ok, that seems reasonable. I got stuck on "there's plenty of engineers who have kids (hence, very much not FIRE)," which seems like an oversimplification of your views.

Thanks for writing that. Agreed, many technical people want the spare time and creativity to work on things that interest them. At some point, for those who enjoy intellectual pursuits, time becomes the limiting reagent, not money.
ryandrake 5y ago
Exactly. Once your needs and wants are met, every extra dollar can just get saved, and means less time until retirement. For this reason, there is never “a point where the money just isn't a motivating factor anymore.” If you are already comfortable and have the trajectory to retire at 55, why not job hop if only to be able to retire at 45? To me, the only point where moar money is truly useless is the day you retire, and even then, maybe you want to pay for your kid’s college or something?
- baash05 5y ago
  I think it's rather personal. I never plan to retire. I want to die coding. The extra cash isn't really a motivation. I've quit a job that I sort of liked, to take a job that paid 10k less, but was something I ended up loving. I didn't notice the difference in my spending habits.
  - Avalaxy 5y ago
    > I never plan to retire. I want to die coding. Yea, but: 1. Do you want to die coding for someone else, on boring enterprisey stuff with bad project managers telling you what to do? 2. What if you physical or mental health degrades when you're older, and you simply can't?

Even if it takes a couple more years, there's no reason to expect that 7% inflation is the norm going forward. (Also consider that people who are doing FIRE certainly don't have much in treasuries. It's going to be mostly in stocks. That certainly carries other risks, of course.)

  Forecasting your spending rate far enough into the future, however, is a very tricky problem if you're trying to retire at 30, especially if you're living through turbulent times. I'd rather work 3 days a week until I'm dead then let my skills start deteriorating now and live the next 60 years in fear that my fixed income won't be able to sustain me.

    spot on. Energy prices are going to rise in Europe for the years ahead so will inflation and then your savings will dwindle... In my country inflation is already around 2.5% years on years.

    As someone who's been working for +10 years now for 3 day's a week I can say: spot on! I've got savings enough for fun projects or holiday's, and my 3 day job simply pays the rent/gas/electricity bills.

      If I may ask, what work do you do / what company do you work for that allows you to only work 3 days a week?

    When you forecast your spending rate, you naturally take some security margin, for example by retiring when your passive earnings gets 1.5x times larger than your targeted spending. And that security margin (which won't be spend most years) will compound. Sure, you might encounter a black swan event which force you out of retirement only 3 years after you started, and at that point your security margin won't have increased your stash by much, but at the same time your skill won't have deteriorated much in 3 years. It also work even if the black swan even happens 20 years after your retirement. You just need to take a security margin your are comfortable with, and project how much you will have after 3, 10, 25 years to see how much you have for unforeseen events.

On $110K income, you could: - Pay roughly $30K in taxes - Spend $30K, which is close to the median American's individual expenditure - Invest the remaining $50K At that rate, you can achieve lean FIRE in 15-20 years. So not quite mid-30s, but not far off. Of course, in a high cost of living area, you might need to spend more than $30K, but you'd also make more than $110K. (For what it's worth, I lived in SF for several years and spent less than $30K annually.)

But, this small subset is what company urges to have. If they are willing to lower down the baseline, there are still quite many engineers around the world.

I haven't really seen a whole lot of evidence that there's any stronger correlation between FIRE and engineers compared to other jobs (in fact, many FIRE blogs are from non-eng people). And conversely, there's plenty of engineers who have kids (hence, very much not FIRE). The vast majority end up going down that route, in fact, at least in my experience.

Why do you say kids are incompatible with FIRE? They add some expense, but it is not insurmountable with a high income like many senior software engineers enjoy. There are prominent FIRE folks with kids -- e.g., "Mr. Money Mustache."
- lhorie 5y ago
  I wouldn't go as far as say they're incompatible; I'm sure it's doable. But there's a pretty big difference in believability between the claim that "engineers are much more likely to be FIRE people, to the extent it makes a noticeable difference in the engineering job market, now of all times" vs "FIRE people w/ kids exist, but are outliers among outliers"
  - loeg 5y ago
    Ok, that seems reasonable. I got stuck on "there's plenty of engineers who have kids (hence, very much not FIRE)," which seems like an oversimplification of your views.

  MMM sells shovels in a goldrush, and got divorced (with relatively young kids) out the blue while selling his white picket fence (albeit a cheap one) lifestyle dream for years. Hardly the one to bring up as an example for a successful FIREee.

> in fact, many FIRE blogs are from non-eng people I don't disagree with your overall point, but I don't think "number of FIRE bloggers who are engineers" is a good proxy for "number of FIRE people who are engineers".

I think you have no idea how bad people are with their money even as engineers.

anonporridge 5y ago
Even a small bleed of a minority retiring early could have huge effects on corporate hiring ability. Especially for senior engineers.

stocknoob 5y ago

Thanks for writing that. Agreed, many technical people want the spare time and creativity to work on things that interest them. At some point, for those who enjoy intellectual pursuits, time becomes the limiting reagent, not money.

ryandrake 5y ago

Exactly. Once your needs and wants are met, every extra dollar can just get saved, and means less time until retirement. For this reason, there is never “a point where the money just isn't a motivating factor anymore.” If you are already comfortable and have the trajectory to retire at 55, why not job hop if only to be able to retire at 45? To me, the only point where moar money is truly useless is the day you retire, and even then, maybe you want to pay for your kid’s college or something?

I think it's rather personal. I never plan to retire. I want to die coding. The extra cash isn't really a motivation. I've quit a job that I sort of liked, to take a job that paid 10k less, but was something I ended up loving. I didn't notice the difference in my spending habits.
- Avalaxy 5y ago
  > I never plan to retire. I want to die coding. Yea, but: 1. Do you want to die coding for someone else, on boring enterprisey stuff with bad project managers telling you what to do? 2. What if you physical or mental health degrades when you're older, and you simply can't?
