Paid,
On k100 accumulated on a pension fund, will make a pension @3% on an annuity pension for 20 years starting @65 = circa 6500 a year of a pension without indexation etc.
Means that to get pension of k24 the value of pension in todays buying terms = @ a minimum k370.
Indexation and spouses/survivors add ons will increase that to well above k 370.
As a stab @ it , average k24 pension in public service = k500 in todays terms.
But spreading that state cost over 20 years makes the k500 just a figure.
The crunch will come when State can,t afford the annual known pension bill,
If that happens , State pensions will be cut !
Apart from people living longer and demographics , no-one can predict the future, we are maybe viewing things a bit too pessimistically.
