I've been web-womble-researching this issue recently to try and get a handle on the basic assumptions, to inform a spreadsheet like Bronte's, and consider different drawdown rates/inflation/interest situations.
It's important to remember throughout the EU around half of retirements are not by choice/age, and that it can be a tough, expensive few years if you do not have any support to reach your state pension... and if you are my age/gender, you've had the state pension goalposts moved on you already by 7 years during your working life...!
Europe’s pension systems can be expected to deliver adequate pensions also to future generations of retirees provided Member States pursue strong policies to enable as many workers as possible to stay in jobs until they reach the statutory pension age, a new report on pension adequacy shows.

In the Irish situation, enforced early retirement is a big issue for women, although employment figures have improved recently for the over 50s.
This year (2019), CSO figures show only 63% of women aged 55-59 were working compared to 80% of men. For the 60-64 agegroup, 47% of women were working compared to 63% of men. Recent coverage of care duties as a cause of the gender disparity has been poorly reported in the media - this as reported by recent ESRI research only affects 7% of the early retirees. In the main, I think the gender difference is likely good old sexism and ageism.
2001 Irish research: over one third of people over 55 would like to retire as soon as possible and 55% only work for the money. But one third of those retired would like to be doing some work [broken link removed]
Also bear in mind, in Ireland, less than 1 in 20 (about 3.7%) end up in a nursing home at the end of their lives. If you come from a family that's seen a lot of aged disability, maybe you are over-worrying about nursing home costs? Average time spent in care is 2 years not the 5 mentioned in some of the posts on this thread.
[broken link removed] - 2013 NERI paper that looks at Ireland and points out the urban/rural divide - a lot more expensive to be out of town. Figures considerably lower than those usually seen in pension provider advertorials but some of the data is from SVDP, who probably have their own angled view on the data.
Which? UK figures based on survey for how much people really spend in retirement - add 10% for euro conversion/different costs here was my guesstimate for conversion plus - crosscheck against your own current spending?
Work out how much you need to save for retirement, see how much retirees normally spend and watch real people's experiences of managing their money in retirement.

(there is a good section on "money purchase pensions" towards the bottom of that long page in Which?)
In my view (but I'm a person who doesn't much care about foreign holidays and new clothes/cars), I think if you have your house paid off, but you are paying for private health insurance, the income you need, including state supports, is probably around €30k/yr for a couple.
But I'm also of the view that the thing to focus on is funding your healthy early retirement to be enjoyable in your own terms. I'm not sure that running out of cash in your later, less-healthy years is actually a bad thing.
What other basic assumptions have people used for their calculations?
