@ClubMan - I've searched in vain over the years for the answer to this question. It seems that no statistical authority or industry group compiles it which is a real shame. Anyway I tend not to trust surveys of pension savers or recipients all that much as people are often ignorant of or reticent about their financial situation.
Anyway this Revenue
data from 2019 shows about 800k tax units (so some married couples) making an average of €3.7k pension contributions annually each. I completely trust the Revenue data btw. CSO show about 2m private sector employees and self employed in 2019 who could have been making contributions against the 800k tax units, which is probably 900k-1m individuals when you account for married couples. It's very hard to know how long people actually contribute for. Some do it their entire lives, many start late in life, some are patchy, and some make no contributions at all. But I'm going to assume something like a 25-year average contribution span who actually make contributions.
Pension saving of €4k per year (assume no inflation) gets you €145k after 25 years if you assume a 3% real return and €190k after 25 years if you assume a 5% real return.
So I think that estimates you see online of around €110k-€120k are on the low side and designed to hook people in and it's probably closer to
Of course median and mean will differ a lot as this distribution will have a long right tail.
Anyway I think it's plausible that
the average Irish worker making pension contributions is on track for something between €150k and €200k in today's money at retirement.
Finally, to give a practical example someone who saved a nominal $2k every year since 1999 and put it in the S&P500 (net 100bps of fees) would have $163k after 25 years. These pension contributions would have been not large by any metric but would have produced a pension pot today well above what the industry claims.
