State pension, employer scheme, private plan: Europe's three pillars explained
Most European retirement systems are built on a similar structure, often called the "three pillars." Understanding the shape of it makes it much easier to see where your own savings fit — and where the gaps might be.
Pillar one: the state pension
This is the public, government-run pension most people are automatically enrolled in through payroll contributions during their working life. It's designed as a baseline, not a full replacement for your working income.
Pillar two: employer or occupational schemes
Many employers offer a workplace pension on top of the state pension, sometimes with contributions matched or partly funded by the employer. These vary widely by country and even by employer, and can be one of the easiest places to leave value unclaimed if you're not paying attention — particularly if you've changed jobs a few times.
Pillar three: private and personal savings
This covers everything you do on your own initiative — personal pension products, investment accounts, insurance-based savings — to top up what the first two pillars provide. For many people, especially higher earners or those with non-traditional careers, this pillar does more of the work than people initially assume.
The OECD average net pension replacement rate for a full-career average earner from mandatory public and private schemes combined — rising to 69.2% once common voluntary schemes are included. Luxembourg and the Netherlands sit among the countries with the highest gross replacement rates in the OECD, both above 70%.

If you've worked in more than one European country, you may have partial entitlements sitting in more than one system — a few years of state pension contributions here, an old employer scheme there. None of these pillars talk to each other automatically, which is exactly the fragmentation problem worth getting ahead of early.
The takeaway
You don't need to optimize all three pillars perfectly — but you do need to know what you actually have in each one. That's the starting point for any realistic retirement plan.
