Get a cup of coffee.
In this thread, I'll help you work out how much money you need to retire.

The goal is simple.
You want to accumulate a *large* portfolio of assets.
How large?
Well, you should be able to quit your job. And you and your family should be able to live comfortably for decades -- just off of the income generated by this portfolio.

This is the crux of the "FIRE" movement.
FIRE stands for "Financially Independent, Retired Early".
The basic philosophy is: keep your spending needs low. Save a large portion of your income. Invest these savings. With luck, you'll be able to retire early.
4/
FIRE advocates have a rule they love to cite: the 4% rule.
The 4% rule says: your annual expenses in retirement should not exceed 4% of your portfolio.
You can use this rule to calculate how large a portfolio you need to accumulate before you can quit your job and retire.
5/
For example, suppose you and your family need $40K/year to live comfortably in retirement.
Then you need to accumulate a portfolio that's at least $1M.
Another way to say this is: your portfolio should be at least 25 times your annual expenses in retirement.
