Buyback of years of study for retirement from the public service

Verified 06 January 2026 - Public Service / Directorate of Legal and Administrative Information (Prime Minister)

You are a civil servant, you have studied in higher education and you want to buy back years of study for your retirement? We present you the information you need to know about this topic.

The redemption of years of study consists of make voluntary contributions so that your years of study in higher education are taken into account for retirement.

Warning  

If you are a contractor, you can redeem your years of study with Retirement Insurance.

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 resulted in a diploma.

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 a Member State ofEuropean Union can also be redeemed.

You must be at least 20 years of age and under 67 years of age on the date of your request.

You must not have applied for your retirement pension.

FYI  

You can apply for the redemption of your years of study as soon as you become a full member of the public service.

You can buy back from 1 to 12 quarters maximum.

You can only buy one integer number of quarters.

Any study period of 90 consecutive days is considered equal to 1 quarter.

Taking into account your years of study can not lead to validating more than 4 quarters per year.

So, for example, if you have acquired 1 quarter of pension insurance as part of a summer job during a year of study, you can buy back only 3 quarters of study for the year concerned.

You have 3 redemption options.

To understand what these 3 redemption options are, you need to understand how your retirement pension is calculated.

Your retirement pension is calculated based on 3 elements:

  1. The gross index treatment that you have held for at least 6 months on the date of your retirement. If you work part-time before retirement, your pension amount is calculated based on your full-time index salary.
  2. The rate of your pension fixed at 75%.
  3. Your number of liquidatable pension insurance quarters in relation to the number of quarters of pension insurance required to qualify for a full pension.
    Liquidatable quarters are the quarters contributed and possibly quarters granted free of charge (called enhancements). Paid quarters are taken into account for their actual duration if you worked part-time except in cases of statutory part-time work or if you overpaid (i.e. if you paid as if you worked full-time).
    The pension is awarded at full rate if you retire before age 67 with a specified number of quarters of pension insurance (this number varies depending on your year of birth) or if you retire at age 67 (regardless of your number of quarters of retirement insurance).

Your pension is calculated as follows:

Pension = Gross index salary x 75% x (Your number of liquidable quarters / Number of quarters of pension insurance required to qualify for a full rate pension)

For example, if you were born in 1964, you must have 170 quarters of pension insurance to qualify for a full pension before age 67.

Example :

If you retire between 62 and 9 months and age 67 with 170 quarters of pension insurance, all of which are liquidatable, you are entitled to a full pension equal to:

Pension = Gross index salary x 75% x (170 / 170)

If you have only 163 of your 170 liquidatable quarters, you are entitled to a retirement pension equal to:

Pension = Gross index salary x 75% x (163 / 170). To this amount is applied a haircut based on the number of quarters you are missing.

Example :

If you retire at age 67 with less than 170 quarters of pension insurance (for example only 168 quarters, of which 165 are liquidatable), you are also entitled to a full pension equal to:

Pension = Gross index salary x 75% x (165 / 170) but no discount is applied to this amount.

When you buy back study terms, you have the choice between the following 3 options:

  • Either buy back quarters that will be taken into account for the calculating your number of pension insurance quarters
  • Either buy back quarters that will be taken into account for the calculation of your number of liquidatable quarters
  • Either buy back quarters that will be taken into account both for the calculation of your number of pension insurance quarters and for the calculation of your number of liquidity quarters.

Before applying for a buyback, it is advisable to simulate the cost of the buyback according to the option you choose using the following simulator:
