How the Two-Thirds Pension is calculated
The Two-Thirds Pension pays a proportion of a career-averaged "pensionable income" figure, scaled by how many years of contributions were paid. This page walks the mechanics — the averaging windows, the scaling rule, and the amounts the pension can never fall below or exceed — without computing a figure: the average itself depends on a wage-revaluation index this section does not carry, so no calculator is offered.
The formula
At a full yearly average of 50 paid or credited contributions, the pension is two-thirds of the claimant’s averaged pensionable income (art. 53(1)). Below that average — down to a floor of 15 — the two-thirds proportion is scaled down instead of being paid in full (art. 55): the proportion is multiplied by the ratio of the claimant’s own yearly average to 50, and the result substitutes for two-thirds in the calculation. Below 15, nothing is payable under this route at all.
art. 53(1) proviso (c): A self-employed person who has paid fewer than 156 contributions after 21 January 1979, where the Director is satisfied the shortfall was due to circumstances beyond their control, has the proportion of two-thirds substituted by (contributions paid after 21 January 1979) ÷ 234 instead of the average-of-50 scaling; otherwise no Two-Thirds Pension is payable under this route at all and the flat-Schedule alternative governs instead.
Pensionable income: the averaging window
“Pensionable income” is not a single year’s wage or income — it is the average of the best-performing years selected from a wider window, and both the window and the number of years selected from it depend on the claimant’s birth cohort and, for the earlier cohorts, on whether they were employed or self-employed/self-occupied.
| Cohort | Years considered | Best years selected (employed) | Best years selected (self-employed / self-occupied) |
|---|---|---|---|
| Born on or before 31 December 1951 | 10 | 3 | 10 |
| Born 1 January 1952 – 31 December 1955 | 11 | 3 | 10 |
| Born 1 January 1956 – 31 December 1958 | 12 | 3 | 10 |
| Born 1 January 1959 – 31 December 1961 | 13 | 3 | 10 |
| Born 1 January 1962 – 31 December 1968 | 40 | 10 | 10 |
| Born on or after 1 January 1969 | 41 | 10 | 10 |
Contribution averaging: a separate window
The yearly average of contributions that sets the proportion above is measured over its OWN reference period — not the pensionable-income window — running from a statutory start date to the contribution year before retirement, for as many years as the cohort below states.
| Cohort | Reference period |
|---|---|
| Born on or before 31 December 1951 | 30 years |
| Born 1 January 1952 – 31 December 1961 | 35 years |
| Born 1 January 1962 – 31 December 1968 | 40 years |
| Born 1 January 1969 – 31 December 1975 | 41 years |
| Born on or after 1 January 1976 | 42 years |
A ceiling on pensionable income itself
Separately from the averaging window, the Act caps how much of any one year’s wage or income counts toward pensionable income at all — a THIRD schedule, distinct from the window above and from the pension-rate ceiling below.
| From | Amount |
|---|---|
| 1 January 2024 | €22,000.00 |
| 1 January 2025 | €23,500.00 |
| 1 January 2026 | €25,500.00 |
| From | Amount |
|---|---|
| 1 January 2007 | €16,207.78 |
| 1 January 2014 | €20,964.36 |
The Act steps this cap up further between 2011 and 2013 by a stated RULE rather than three printed cash figures, so those interim amounts are not shown. Thirteenth Schedule (7)(b)(iii): from 1 January 2014 the €20,964.36 base is increased annually by 70% of the percentage increase in the national average wage for the previous calendar year plus 30% of the previous calendar year's inflation rate, both as published by the National Statistics Office. Those NSO percentage publications are not in this corpus, so the 2026 resulting cap for the born-1962-or-later cohort is not computed.
Floor and ceiling
The Guaranteed Minimum Level is €198.50/week for a person married and maintaining a spouse, and €194.50/week for any other person (Twelfth Schedule Table C), for anyone whose yearly average of contributions is not below 50. At the other end, a claimant qualifying for the full Two-Thirds Pension can never receive more than €281.64/week (Twelfth Schedule Table K, art. 54(b)).
Revaluation and annual increases
Thirteenth Schedule (1)/(2)/(3)/(4)/(5): each selected year's wage/income figure "may be increased by the applicable wage increases required by law to be awarded generally" in respect of each subsequent year up to retirement — for an employed person, capped so "each such increase is less than the net increase obtaining from year to year between one [wage] and another" for self-employed/self-occupied persons. The "applicable wage increases required by law to be awarded generally" are set by National Standard Orders under the Employment and Industrial Relations Act (Cap. 452) — a different Act, not vendored in this corpus. Cap. 318 states the rule but never tabulates the resulting annual percentages.
Once in payment, pensions increase under art. 90A: art. 90A: whenever Government awards a cost-of-living increase in the rate of the National Minimum Wage under the Employment and Industrial Relations Act, every pension payable under Cap. 318 is automatically increased — from the date of that award, or the date the pension becomes due, whichever is later — by an amount equal to two-thirds of the cost-of-living increase, unless a higher increase is already due under the Act's own provisions (in which case, save as the Sixth and Twelfth Schedules separately provide, art. 90A does not apply). A married National Minimum Pension recipient's share was four-fifths rather than two-thirds until this was withdrawn with effect from 1 January 2018. No standing wage/price formula and no fixed calendar month govern the pension's own uprating: the 2/3 share is stated in Cap. 318, but the AWARD it applies to — the size and timing of each year's National Minimum Wage cost-of-living increase — is fixed under the Employment and Industrial Relations Act, an external instrument not vendored here.
Why there is no calculator on this page
The average this formula scales against is a career-long figure built from years the Act selects individually and then revalues by an external wage-increase index this payload does not carry (see above) — nobody holds that number, so there is no honest input a form on this page could take. Cap. 318 arts. 44-51 (Retirement Pension / Increased Retirement Pension / National Minimum Pension / Guaranteed National Minimum Pension, priced off the Twelfth Schedule Tables A-C's flat weekly rates) remain live law, extended by art. 48's 2018 proviso to every insured person regardless of first-entry date. art. 57 pays whichever of that route and the Two-Thirds Pension modelled in this formula block is more advantageous to the claimant. This payload does not compute the flat-Schedule route or the art. 57 comparison — a claimant's actual weekly pension may be the flat-Schedule amount, not the Two-Thirds figure this formula produces, and no consumer of this payload may treat the Two-Thirds result as final without also pricing the alternative.
