Under what circumstances does a 4% withdrawal rate deplete an investment account?
I'm doing my own math in a google sheet and I can't for the life of me figure out how withdrawing 4% of the starting balance every single year would ever deplete the retirement balance.
What am I missing? I know the market isn't going to grow every single year but it's also not going to be flat over 30 years?
Sorry if this is the wrong sub for this question.
