I have a friend who did exactly that. We worked together in tech for 10 years, he lived super frugally here in the Bay Area, and then when he had saved $1M, he retired back to his native Kansas, bought a house for under $100K, and just kicks back enjoying his time.
I've been trying to work it out, but mostly I just need to add to the pile until the passive numbers work out better an do so reliably in good and bad years. $40K on $1M means you have to be 100% in risk assets (stocks). Technically, if you had your whole million in say, an S&P 500 index fund, you could probably safely withdraw 4%, e.g. $40K/year and still grow your principal "most years." You couldn't last year, though.
I earned somewhere around $55K last year without lifting a finger except to judiciously manage the accounts (which takes around 1hr a day), file taxes (10-20hrs once a year), and manage few other things like the odd 401K rollover and what not. It takes the edge off of my main career, but I'm not ready to depend on just that side yet. Inflation is a cruel bitch, always moving the goalposts further away.
My main "plan" is to ditch the coding job if I can find some $40-50K role someplace not in tech, but that would probably still have to be a 40hr/FTE deal so that doesn't give me any additional free time although it probably would be a hell of a lot less stressful. I'm weary of the stress and outsized corporate nonsense, but I still love tech.
I'm open to any ideas.
Edit: Also to clarify, I absolutely agree with the living frugally thing, and think most people would be in general better off if they focused less on spending every penny they make.
I have noticed that my friends and family that grew up in higher cost of living, higher income areas and went into the standard higher paying careers (doctor/lawyer/finance/engineering) are more financially secure than those who weren't as fortunate or focused on the rat race. At what mental/other cost though, I can't say.
Edit: The most financially secure are those who invested in commercial real estate and development.
People going the DINK route are mostly prioritizing careers over life. It's a vicious cycle for many, who end up changing their mind and spending alot of money and opportunity cost trying to make up for it.
If you choose to join the cool kids club, you're paying the price of admission. I coach little league ($120/season) and do all sorts of activities with the kids that are fun, enriching and not outrageous. My kids will not see the Louvre or work on their Spanish in Barcelona on a school trip, but will somehow muddle through.
- Daycare is 18k per year.
- Extra seat on airplanes, depending on your travel habits could be 2k
- Food, diapers, increased medical premiums might all total around 1500
That's like a 30% pay cut for a lot of people.
Wholly disagree with the purchasing power notion. I have lived frugally for years and 1M is enough to set me up for life (providing I don't have kids). This is because budgeting is now an ingrained habit and I wouldn't suddenly stop budgeting just because I can now spend more on things.
