Look at US Social Security ...they pay 5 pct to get a $2k monthly cheque (this is the max amount). The average payout is about $1300.
CPF makes you pay 20 pct and after accounting for inflation, you have actually lost money. Say you put 10k a year, over 30 years, your final total after compounding interest is $450k. If you invest this amount yourself just by buying an S&P etf, you would have net more than $1.3 million, assuming an average return of 8 pct. For the 1980 - 2013 period, the average return is 13 pct. The difference is $850k!!!!!!!
The CPF is a rip-off scheme, not one to help you save for retirement.
So comparing with the US now.... If their scheme is as good or perfect as you mentioned, why is it that 80% of the Americans doesn't own a house, they only rent...
