Predictions, particularly about the future, are always difficult.
The current State Pension (for a couple) is circa €400pw, so just over €20,000pa. Based on your current salary, that’s almost 50%. I know your salary may increase in the future, but so may the State Pension.
Therefore any private pension will be in addition. If your deferred pension is c€13,700 (not clear whether that is the projected pension to include re-valuation to age 65 or the current figure which will be re-valued going forward) that will bring you further up. And finally anything from the DC scheme will only increase your overall pension.
It is impossible to predict what will happen to the State Pension:
-will it become means tested
-will it increase in line with inflation
-will it move to a start age of 70, etc
But my strategy would be to maximize as much as possible. The 15% contribution to the DC scheme is very reasonable. So overall I think you are on a reasonable path.
