"Start providing
A person who aspired towards an annual pension of €100,000 when they reached 65, and started providing for it at 25, would have to put €65,400 into their pension fund every year, with the contribution assumed to increase by 2.5 per cent per year. If they wanted to retire at 60 and started making contributions aged 20, the equivalent figure would be €74,250.
If a young person aspired towards a pension of €24,000 per year, which is just below the average for retired civil servants last year, and wanted to retire aged 65, they would have to start investing €15,750 annually from age 25. That is the equivalent of one third of gross income. If they wanted to retire at 60 and started investing at age 20, the starting contribution would be €17,850.
