Verified 01 January 2026 - Public Service / Directorate of Legal and Administrative Information (Prime Minister)
Are you an employee and would like to know whether certain periods during which you have not contributed to retirement can still be taken into account for your retirement? It is possible to redeem periods without contributions in making voluntary contributions for them to be taken into account and improve your retirement. We present you the main redemption possibilities.
The buyback of quarters allows you to pay voluntarily of contributions to ensure that periods during which you have not contributed for retirement be finally taken into account when you retire by Pension Insurance.
You can in particular redeem the following periods:
- Higher years of study
- Company internships completed as of March 15, 2015 as part of higher education
- Incomplete years for which you do not have 4 quarters of pension insurance recognized (validated) by the Retirement Insurance.
Others life situations may give rise to voluntary payment contributions (period of criminal work, period spent as a third-party volunteer with an invalid or infirm family member, periods during which a person has been registered as a high-performance sportsman on the list established by the Ministry of Sport, etc.).
The years of higher education and the incomplete years may also be redeemed points from the supplementary pension of Agirc-Arrco.
What are the periods of higher education that can be redeemed?
Study periods that can be redeemed must have been completed at one of the following institutions:
- Higher education institution
- Higher Technical School
- Grande école
- Preparatory class for a major school
- High school post-baccalaureate class.
These periods of study must have given rise to thegraduation.
Admission to a major school or to a preparatory class for a major school is equivalent to obtaining a diploma.
Periods of higher education completed in one of the following countries may also be redeemed:
- Countries of theEuropean Economic Area
- Switzerland
- Country linked to France by a international convention on social security.
What are the conditions to be met to buy back the years of higher education?
You can apply for the redemption of your higher education years if you have at least 20 years and under 67 years.
You must not have applied for your retirement pension from Retirement Insurance.
To be able to buy back and validate your years of study at the Pension Insurance, Retirement Insurance must be there 1re pension fund to which you contributed after your studies.
How are periods of higher education counted for retirement?
The redemption request is taken into account for a integer number of quarters.
Any study period of 90 consecutive days is considered equal to 1 quarter.
If the 90-day period spans 2 calendar years it may be regarded as having been carried out in one or other of those years.
Each year may comprise only 4 quarters.
Only 12 quarters in total may be redeemed for the following reasons:
- Higher years of study
- Incomplete years for which you do not have 4 quarters of pension insurance recognized (validated) by the Retirement Insurance
- Periods during which you have been registered as a high-performance sportsman on the list established by the Ministry responsible for sports and which have not been taken into account by another basic pension fund
- Periods during which you have held a local mandate.
What is the buy-back of school years for retirement?
You have 2 redemption options.
To understand what these two options are, it is necessary to understand how the retirement pension is calculated by the Retirement Insurance.
Your retirement pension from the Retirement Insurance is calculated based on 3 elements:
- Your average annual salary of your best 25 years
- The liquidation rate of your pension, which may be at most 50% if you are entitled to a full rate retirement.
The pension is awarded at full rate mainly in one of the following 2 cases:- You retire before the age of 67 with a specified number of quarters of pension insurance which depends on your year of birth
- Or you retire at age 67 (regardless of your number of quarters of retirement insurance).
- Your number of quarters of pension insurance in relation to the number of quarters of pension insurance required to qualify for a full pension.
Your pension is calculated as follows:
Annual Pension = Average Annual Salary x Rate x (Your number of Quarters of Retirement Insurance / Number of Quarters of Retirement Insurance Required to Qualify for Full Rate Retirement)
For example, an employee born in 1964 must be at least 62 years, 9 months and 170 quarters of pension insurance to be entitled to a full pension.
Example :
If he retires between 62 years and 9 months and 67 years with 170 quarters of pension insurance, he is entitled to a full retirement pension equal to:
Annual pension = Average annual salary x 50% x (170 / 170), i.e. for an average annual salary of €30,000, an annual pension of €15,000 raw
Example :
If he retires at age 67 with less than 170 quarters (e.g. only 159), he is also entitled to a full retirement pension equal to:
Annual pension = Average annual salary x 50% x (159 / 170), i.e. for an average annual salary of €30,000, an annual pension of €14,029.41 raw
Example :
If he retires between 62 years and 9 months and 67 years without having 170 quartersHowever, he is not entitled to a full retirement pension. In this case, his pension is haircut i.e. a reduction in the rate of 50% 0.625 per missing quarter.
The number of missing quarters selected is the most advantageous of the following numbers:
- Number of quarters between retirement age and age 67
- Or the number of quarters missing between his number of pension insurance quarters and the number of pension insurance quarters required to qualify for a full pension?
For example, if he retires on his 63rd birthday with 159 quarters:
- The number of quarters between the starting age (63 years) and 67 years is 16 (4 years).
- The number of quarters missing between his number of pension insurance quarters (159) and the number of pension insurance quarters required to qualify for a full pension rate (170) is 11. It is this more advantageous number that is retained.
The liquidation rate shall be reduced to: 50% - (11 x 0.625) = 43.125%.
The pension shall be equal to:
Annual pension = Average annual salary x 43.125% x (159 / 170), i.e. for an average annual salary of €30,000, an annual pension of €12,100.37 raw.
When you buy back quarters, you have the choice between 2 options following:
- Either buy back quarters that will be taken into account only for the calculation of your liquidation rate (to limit the discount)
- Either buy back quarters that will be taken into account both for the calculating your liquidation rateand for the calculating your number of pension insurance quarters.
Warning
Quarters validated following a buyback are not taken into account for the examination of the conditions for entitlement to early retirement.
