How much money do you need to retire, and what variables need to be considered?
Any useful links that can help determine a dollar figure?
Edit*
I have thought that if you have enough money invested, and it pays a sufficient return to cover all living expenses, you can retire at any age.
As long as income sufficiently surpasses expenses.
But I would like to hear about variables that are wise to consider.
Thank you everyone.
@Whomastadon: Depends which old folks you're talking about. Ex prime ministers get that back 10 fold.
