Ireland: the State Pension age that did not rise
The State Pension age is 66; a planned rise to 67 was reversed. Ireland is the exception in this list, nearly every other country here has an age that is climbing, either on a legislated timetable or with life expectancy. Ireland's increase to 67 was legislated and then cancelled before it took effect, and the age has stayed at 66.
That has a practical consequence for the projection. Where a British, Dutch or Swedish reader should treat the age on this page as provisional, an Irish one can reasonably take 66 as the working assumption, while noting that the reversal is itself the evidence that this age is a political decision rather than an actuarial one.
The State Pension (Contributory) provides part of retirement income and is not modelled here. It is a flat rate built on PRSI contributions rather than a percentage of what you earned, so it covers a much larger share of a modest income than a high one. The higher your salary, the more of the gap the portfolio on this page has to close, and the further above zero the income target belongs.
Irish assumptions: a 6.5% nominal return and 2% inflation, a real return of 4.41% a year.
