How to apply for pension?
You must apply for a pension from the pension authority in the country in which you live. If you have never worked in the country where you currently live, this will be passed on to the country where you last worked. They are responsible for processing the claim and compiling the records of contributions paid in all the countries where he or she worked.

Age of Retirement
In some EU countries you have to wait longer before you can retire than in others.
You can only get a pension from the country where you now live (or last worked) when you have reached the legal retirement age in that country. If you have accrued pension rights in other countries, you will not receive the corresponding part of the pension until you reach the statutory retirement age in the countries concerned.
Therefore, find out in advance in all countries where you have worked what your situation will be if you change the date on which you start receiving your pension. If you start getting a pension sooner than another pension, this may affect the amounts you receive.
For more information, consult the pension authority in the country where you live and/or in the countries where you have worked.

How is your pension calculated?
The pension authorities in each country where you have worked will take into account the contributions paid into their systems, the amounts paid in other countries and the periods during which you have worked in the various countries.
Each pension authority calculates the part of the pension it has to pay you, taking into account the periods of work in all EU countries. To this end, it adds up the periods completed in all EU countries and calculates the pension to which it would have been entitled if it had contributed to its own scheme for the whole of the total period (the so-called notional amount).
This amount is then adjusted to reflect the actual length of time you were insured in that country (the so-called pro-rata benefit).
If you qualify for a pension regardless of periods completed in other countries, the pension authority calculates the national pension (the so-called independent benefit)
