To be financially independent(not have to work again) if expenses are $25000 p.a. you would need $625,000, this would last for a 30 yr period also known as a 4% safe withdrawal rate.
To make sure it lasts longer than 30 yrs times expenses by 30 i.e. a 3% SWR, you would need $750,000.
To me rich is having over a couple of million but FI financial independence , freedom , choice to work or not ,live your life as you choose is just as good.
Expenses * 30 will get u there for a nice early retirement..
So for instance that cheap iphone at only $100 per month $1200 p.a. you need to save an extra $36,000 for your retirement, so you can have the joys of sending lols and
all day.
