In France, it is obligatory to pay into both the retraite de base (basic state pension scheme) and the retraite complémentaire (supplementary private pension).

The basic state pension is financed by the Social Security system. It is based on your average annual salary, a standard rate, and the length of time you have paid into the pension system.

Employees contribute a certain sum each month to the Social Security system and to their complementary pension schemes. The contributions are deducted directly from your salary.

The legal retirement age is 64 if you were born after 1 January 1968.

If you were born between 1 September 1961 and 31 December 31 1967, the legal retirement age increases gradually from 62 to 64 at a rate of 3 months per birth year.

To be entitled to a full state pension, you need to have contributed for a certain number of annual quarters. If you do not have the required number of quarters, you can still retire at the official retirement age, but you will not be paid a full pension.


Complementary private pension - AGIRC -ARRCO

AGIRC -ARRCO is a compulsory pension fund set up for all staff members in the private sector in France. In order to benefit, you must pay into the fund. The value of your pension is calculated based on the number of contributions paid (points acquired) during your working career, multiplied by the value of each point.

To retire with a full pension without having the required number of quarters, you will have to be 67 years old.


Progressive retirement  

Retraite progressive is a scheme which allows you to work part-time while receiving a proportion of your basic pension and a proportion of your complementary pension.

Consult the AGIRC-ARRCO website to discover more about various plans and options (in French):
