Is 1MM enough to retire?

No, not enough.

if you wanna live off of 25k a year...

Personally, at minimum I would need 2MM to "retire" and start running my own money full time

If you live frugally, maybe... even then, retiring at 45 is quite young. For the extra 15-20 years before a normal retirement, you will most likely need more.

No in general. But it greatly depends on your personal situation and spending habits. If you live in a cheap place, have a house paid off with low property taxes and don't have kids, maybe if you spent very minimally but you'd be living like a hermit in the Ozarks. And with life expetancy where it is now you could be stretching that out a long time and your SS check isn't going to be very big because you wouldn't have been contributing for 20 years.

@couchy has it about right. You'd have a good chance if you moved to a remote fishing village in Guatemala. However, if you want to live in the US, it's not very practical.

Nope, and according to CFA, you have significant longevity risk.

Would investing in blue chip dividend growth stocks with bonds, equities, REITS, etc. be enough to cover my living expenses? They pace with inflation and I suppose I could earn 4% return each year, which should be enough for a single person with no debt.

assets are only 1 piece of the puzzle. if you still have liabilities (not just debt, but things like kids, aging parents, etc) and expenses and no other sources of income (your SS is probably unimpressive at only age 45) like a pension or partnership interests, then $1mm is a small sum on which to retire.

why do you want to retire? why not switch industries, I'm sure you have an interesting story and may be able to make the leap to something else.

many places in latam / se asia you could make this last pretty easily, wouldnt have to be a remote fishing village either ,

Thailand baby! I think you could live comfortable on $400k out there ($20k a year @ 5%). Probably want more like $600k if you want to fly back to the U.S. once a year...

Buy gold. Inflation is coming.

OP, I'm curious, are you really 45, or close, with $1MM and want to retire or are you running hypotheticals as a 25 year old thinking you want to retire ASAP on as little as possible at some point in the future?

And @andylouis and @jankynoname are correct: you could take that money to parts of South America or SE Asia and live pretty well. Take that to rural India and you could be a god.

Would really be tough. What makes it really hard is if you plan on having a family and needing to support them

What if you owned your house outright?

Unless you plan on living alone on 20k a year and not having kids or any dependents... NO
