The 4% Rule.... how does it really work? Are your numbers right?

[Anthony W.]

So just a little clarity on the 4% rule. Please any and everyone comment. I get the whole concept of the 4% rule but im just hung up on one portion and dont laugh at me lol. So does this 4% rule go into action once you retire...example if i retire at 62, i do 4% of what i need to leave from 62 until i think i will pass on (pretty morbid), Thanks for any and all comments.
