How much money do you need to retire?
It all depends on your age, lifestyle etc., but I'd argue that anyone can easily retire with 1.5 million, at any age. It doesn't matter if you're 65, 45, or 25, if you have 1.5 million and invest it with a 5% return you'll be making 75k per year without even touching the principal. If you have 2 million you'd make 100k per year, definitely more than enough to retire on.
