If current pension levels and rules were in place in 2048 (a big call, I know), then by my calculations $410,000 dollars (in current day dollars) between a couple would be plenty enough for a comfortable lifestyle when you include the part pension, assuming they retire at 67.
It's a shame the report doesn't specify the amount for a comfortable lifestyle. My recently arrived superannuation statement tells me I need $41,000 as a single person per year in retirement to be comfortable. Ha!
I'm planning on retirement income of 35k for the two of us, which should yield a (nearby) overseas holiday every second year. That's more than comfortable.
Superannuation companies don't actually want you to retire, because then you stop giving them money. My annual report also projects my future super balance using 3% returns after inflation, and shows this chart of savings disappearing to nothing at age 84. They have a nifty looking on-line calculator, but they don't actually let you change the return rate, the withdrawal rate or age at death. I'm sure they're just covering themselves, but it's as if it was designed to scare you into keeping working, and putting money into superannuation.
