I was just having this conversation with my two bosses. The 71 yr old, won't retire one says, you'll need at least 2 million to retire, and in fact, why don't you talk your husband into working past 65 to 68 to boost your nest egg. The other, younger one says, well you'll need $70k a year, so at least a million, but maybe not 2.
I said thanks, but DH is retiring in 6 years, at 50, and I'll follow him out the door as soon as our investment assets hit $750k, as our expenses are around $30k a year.
Ah, nothing like working in the land of high net worth folks, with expenses to match!
