Not sure if it is possible to give an exact answer to this. But I can say that when looking back at my records, at age 51 years I have 10 times the amount I had at 32 - and that's without significant extra contributions or anything, just the SGC contributions skimmed off my salary / bonuses each year, and into a "growth" option pooled fund. I expect this to double again before I am 60 as well, even allowing for the current market crash / forced recession.
