The system works as designed. That’s the problem.#
Every good bug report has two lines: expected behaviour and actual behaviour.
Expected: you work for 40 years, pay in every month, and then keep living roughly the way you lived before.
Actual: you get a base income that hangs on average wages and on how many people are still paying in. Nobody hacked anything. The system runs exactly to spec. The spec just doesn’t say what you were told it says.
And it’s the same spec in Rome, Warsaw, Vienna, Madrid and Berlin. Different logos on the letterhead, same architecture.
Pay-as-you-go in one paragraph#
Most state pensions in Europe run on pay-as-you-go. Your contributions aren’t invested for you. Not a cent. They go out again almost immediately, to the people who are retired right now. What you get in return is a claim – points, credits, an account balance that exists on paper – on the contributions of whoever is working when you’re old.
So there’s no pot. There’s a pipe. What comes out at one end depends on what goes in at the other.
If a private company paid its old customers with the money of its new customers, the founders would be explaining themselves to a judge. When the state does it, it’s called a contract between generations. You never signed it, by the way.
Fewer shoulders per pensioner, everywhere#
A pipe lives and dies by one ratio: payers to receivers. The OECD publishes it for every member country, together with the pension each system promises to somebody who starts working today.
Guess first
Roughly 1.3 people of working age per pensioner. And not all of them will have a job.
| Country | People 65+ per 100 aged 20–64, 2024 | Same, 2054 | Promised pension, % of pay | Pension age |
|---|---|---|---|---|
| Italy | 42.0 | 76.6 | 70.6 | 70 |
| Spain | 34.9 | 76.2 | 80.4 | 65 |
| Poland | 33.7 | 67.8 | 28.6 | 65 |
| Austria | 34.1 | 61.1 | 74.1 | 65 |
| Germany | 39.8 | 59.7 | 42.1 | 67 |
| France | 40.2 | 53.4 | 56.6 | 65 |
| Ireland | 27.0 | 51.1 | 24.3 | 66 |
Source: OECD Pensions at a Glance 2025. The promised pension is the gross replacement rate: gross pension as a share of gross pay for a man on average earnings who starts work at 22 in 2024 and works without a gap until the pension age in the last column. Mandatory schemes only. Poland: figures for men.
Read one row. Italy has 42 people over 65 for every 100 of working age. In 2054 it’s about 77. That’s 1.3 people of working age per pensioner, and not all of them will have a job.
Now read two columns together. Spain promises 80% of pay and heads for 76 pensioners per 100 people of working age. Italy promises 71% and heads for 77. One of those two numbers will have to give, and demography doesn’t negotiate.
Poland and Ireland did the cutting in advance: the promise is below 30% of pay. At least nobody can say they weren’t told.
The EU as a whole, counted by Eurostat with a slightly different yardstick (65 and over per 100 people aged 15 to 64): 34.5% on 1 January 2025, up from 29.0% ten years earlier.
Now your country.

Three knobs, no magic#
A system like this has exactly three knobs: higher contributions, a later retirement age, or a lower pension relative to wages. Tax money can plug the holes, sure. Guess who pays the taxes.
Every reform is a remix of the same knobs with a fresh name and a press conference. None of them adds money that wasn’t there, because politicians don’t have money. They have yours.
Worked example: Germany#
Take Germany, because I know it best and the numbers are public. Your country has its own versions of every figure below, and they’re worth ten minutes of searching.
The German statutory pension has run mostly on pay-as-you-go since 1957. The price of admission in 2026: 18.6% of gross pay, split between employee and employer.
Guess first
Today it’s about 2. Same pipe, a third of the shoulders.
| Year | Contributors per old-age pensioner, Germany |
|---|---|
| 1962 (West Germany) | 6 |
| 1973 | 4 |
| 1988 | 3 |
| Today | about 2 |
The number German politicians love to fight about is the pension level, fixed by law at 48% until 2031. Most people hear “I get 48% of my last salary”. Yeah, no. It compares a standard pension – 45 years of contributions at exactly average pay – with current average pay, both after social contributions and before tax. It’s also not the OECD’s 42.1% from the table: different yardstick, same direction.
Three traps hide in there, and you’ll find all three in most other systems too.
The cap. Earn twice the average and you collect two points a year, but only up to a ceiling (€101,400 of annual pay in 2026). So the better you earn, the wider the gap between salary and pension.
The full career. 45 years is a long time without studying, without a gap, without part-time work, without being self-employed and without moving abroad. Every one of those costs points.
The expiry date. The law guarantees the 48% until 2031. After that? A political decision nobody has made yet. The people who’ll make it have a planning horizon that ends at the next election. I wouldn’t build my life on it.
Inflation: the number on the letter isn’t what it buys#
Your pension statement shows an amount. Check whether it’s in today’s money. The German one isn’t: the Deutsche Rentenversicherung itself points out that its projection ignores the loss of purchasing power.
The European Central Bank aims for 2% inflation a year. At exactly 2%, €1,000 in 30 years buys what about €552 buys today. Yes, pensions get raised over time – in Germany by 4.24% in July 2026 – but a figure on a letter and a standard of living are two different animals.
The patch#
I don’t think state pensions will disappear. Pensioners vote, and politicians can count at least that far. A state pension pays for life, and that’s worth something. But I expect the promises to shrink, in every country in that table, so I’d book mine as a bonus. Nice when it shows up. Not the thing your life depends on.
The plan is the part you build yourself: know your gap, invest every month, earn more over time. Nobody is coming to save you, and honestly, that’s the good news: you’re the only one in this story with a reason to get it right. The goal isn’t a rocking chair, by the way. It’s the point where work becomes a choice. That’s Plan B, and it’s mostly maths and habits.
First move: get a rough number for your own situation. The calculator lets you pick your country.
