Quarters required for a full pension: 170, 171 or 172 depending on your generation

According to the official information sheet on service-public.fr, verified on August 14, 2026, a full pension before age 67 requires 170 quarters of contributions if you were born between January 1, 1963, and March 31, 1965; 171 if you were born between April 1 and December 31, 1965; and 172 if you were born in 1966 or later. For those born between 1964 and 1968, the official announcement of February 27, 2026, confirms these figures for pensions taking effect from September 1, 2026. At age 67, a full pension is automatically granted regardless of the number of quarters of contributions.

This page deals with the required insurance period and how a quarter is calculated. It does not cover the retirement age, which is addressed on another page. Nor does it cover increases in insurance periods for children, the situation of people who have contributed or who live abroad, or special schemes and schemes other than those for private sector employees.

What does "full rate" mean?«

A full pension is a pension granted without any reduction, meaning without any decrease in its amount. The number of quarters required is calculated based on your total insurance period, across all pension schemes, and not on a single scheme.

The table by generation

Here is the number of quarters required for the full rate before age 67, according to the date of birth, as given in the official fact sheet "Full rate retirement: conditions" (verified on August 14, 2026).

This table is from the official record verified on August 14, 2026. The comparison between before and after September 1, 2026, presented in the following section, only concerns the generations from 1964 to 1968. The quarters are counted across all schemes.

What changed on September 1, 2026

The Social Security Financing Act for 2026 (Law No. 2025-1403 of December 30, 2025) suspends the increase in the legal retirement age and the increase in the required contribution period until 2028. The new rules apply to pensions taking effect from September 1, 2026. This page does not explain what will happen after 2028.

The official news table only includes the 1964 to 1968 birth cohorts. The effect on the number of quarters relates to the 1964 and 1965 cohorts:

If your retirement takes effect before September 1, 2026, the right-hand column does not apply. If it takes effect on or after that date, then it does.

That counts as a quarter

A quarter is validated from an income threshold or an equivalent period.

• Private sector employee: an income threshold. The official document, verified on January 1, 2026, calculates the threshold by multiplying the gross hourly minimum wage (SMIC) of January 1 by 150 hours. It indicates €1,803. A quarter is validated when your gross annual income reaches this threshold.
• A maximum of four quarters per calendar year. A high income does not validate more than 4 quarters in a year.
• Work-related illness or accident. 1 quarter is validated for each 60-day compensation period, with daily allowances.
• Maternity. One quarter is validated for each 90-day compensation period.
• Internships. One term is validated for each 50-day internship period.
• Unemployment benefits. One quarter is validated for every 50 days of unemployment, consecutive or not, up to a maximum of four quarters per calendar year. This record was verified on August 28, 2025.

For unpaid unemployment, the rules depend on your age and career: they are checked in your file.

If you do not have the required number of quarters

Early retirement is possible between the legal minimum age and 67, but the pension is then reduced by a penalty, except in specific circumstances (long career, disability, invalidity, for example). The mechanism is as follows:

• the rate of 50 % is reduced by 0.625 % per missing quarter; ;
• the number of quarters retained is the smaller of two differences: the missing quarters up to age 67, or the missing quarters compared to the required number; ;
• the resulting number is rounded up to the next digit; ;
• it is limited to 20 quarters, i.e. a minimum rate of 37.5 %.

At age 67, you are entitled to the full pension rate regardless of the number of quarters you have contributed. A detailed calculation of the reduction is covered on another page.

Long career: same number of quarters

For early retirement due to a long career, the official table (in the case of an activity started before age 20) gives the number of quarters required:

The rules for long careers are changing from September 1, 2026. This page does not detail the conditions for starting work (before 16, 18, 20 or 21 years old) or the retirement ages.

Numerical example (fictitious profile)

Situation. Marc was born on July 1, 1966. He is a private sector employee. His legal retirement age is 63 years and 3 months: he can retire on October 1, 2029. The required contribution period for his generation is 172 quarters. On that date, he will have 160 quarters (based on his profile). His average annual income is €40,000 (based on his profile). It is assumed that all his quarters, both the initial 160 and subsequent ones, are credited to the French National Retirement Insurance (Assurance retraite): the basic pension formula takes into account the quarters credited to the National Retirement Insurance.

Issue. He is 12 quarters short of qualifying for a full pension. Should he retire at 63 years and 3 months or continue working?

Strategy. Compare two starting dates: October 1, 2029 and October 1, 2032, three years later. Assume he completes 4 quarters per year between the two dates.

Result.

Retirement benefits are calculated here according to the formula in the official "Basic Retirement Amount" document: average annual income × rate × (retirement insurance period ÷ required insurance period for a full pension). Official documents do not all formulate the denominator in the same way: the exact amount should be verified with the official source or your pension fund. Retirement in 2029: €40,000 × 42.5 × 160 ÷ 172. Retirement in 2032: €40,000 × 50 × 172 ÷ 172.

This profile is fictitious. The calculation uses the same average annual income in both cases. It does not take into account salary increases, supplementary pension benefits, or the three years of pension payments that Marc would not receive if he continues to work. The figures illustrate the mechanism and do not predict your individual situation.

What changes depending on your situation

• Your exact date of birth March 31 and April 1, 1965 do not give the same number.
• The effective date of your retirement : before or on or from September 1, 2026.
• Your periods of non-contribution : illness, maternity, internships, unemployment.
• Your other plans : the calculation is done across all schemes, but each fund calculates its own pension.
• Special situations : long career, handicap, disability.
• Your average annual income : it is included in the calculation of the amount, according to the formula in the official document.
• Quarters validated for retirement insurance : these are the ones that the basic pension formula retains, according to the official document.
