And when you retire, inflation actually increases. By that stage, you don't have any kids to put through university and will have paid for your house, etc.
In the 1970's and up to about R 1985, a R3m nest egg was considered adequate to retire on, with interest rates above 10%, annuities were paying R 14k per million so a R3m portfolio would bring in R 42k a month, more than adequate
Since 2008 that all changed, an annuity (if you believe in these) maybe gets you R 7k per R1m, so you need much more money put away. Of my circle of retired friends, say about 30, only 10 are comfortably off, can do what they like and don't have to watch the pennies. The other 20, in varying degrees, have to be very careful, accept handouts from their kids, don't travel much and don't go out to meals. And these were mostly guys with well-paid jobs, engineers, doctors, etc. The winners are those receiving an oveseas pension from a company (not the British Govt) or a country like Switzerland or Germany.
If you contributed an average of R 550 a month to a pension fund in Switzerland (and were a Swiss national) then you can expect a monthly pension of around R 83 000. Given that the value of the SFr increases year by year via a vis the Rand, this takes care of inflationary trends in SA
I don't want to get into a discussion of retirement income, since this is not the heading of this thread, but you have to be aware of the future. You can guarantee that inflation will never go away, at least in SA
