Could you retire on $1 Million?

A big No,

Only if I had invested them somewhere where I am earning a good 5 to 10% return.

Totally! Retiring on $1 million in my country is sth absolutely doable! but hey, I'm in my 30s, making that cash ain't that easy, haha! Gonna keep hustling and living it up for now.

If the 1 million dollars is in India. Yes with this amount you can retire here and live a comfortable life

In Germany you would have to live VERY frugally and/or be very lucky with your investments to retire on that money. That is, if you still expect to live for quite a few decades.

Depends on where, your life style, and age. But for an middle-class life style in any western country, that is more often that not a no.

There is the 4% rule, popular in the FIRE movement (Financially Independent, Retire Early). It is a rule of thumb of how much you can withdraw from your portfolio per year, taking into account future returns and a 30-year retirement horizon. So, roughly, will you get by with $40,000/year? If so... maybe you could? Even within the same country, if you live in a big city versus countryside the cost of living is vastly different. So your milage may vary.

No. Definitely not with a family in the US. I tried "retiring" for a year about 6 years ago, and living off the income of my digital products. I realized it is more exciting to be building.

in the Philippines, YES!

$1M is where you can start scaling, but not to retire!
