Frac, I recall many years ago (early 90's) when I was at a Super presentation and the question about the amount of yearly super income was required for retirement.
The presenter replied that $43k p/a was the minimum for a couple which bemused me because I wasn't even earning that amount with a family, mortgage and one income!
Q. How much do you need to retire ?
A. What lifestyle do you want in retirement, eg, business class holidays every year and new Merc every 3 years!
Only you can answer your own question, but I would imagine that very few would have your level of Super when retiring.
