Publié le null - Legal and Administrative Information Directorate (Prime Minister)

The new rent benchmark (IRL) was published on 14 April 2023 by the National Institute of Statistics and Economic Studies (INSEE). Taking into account the 3,5 % cap on the change in the benchmark rent index established by the Law for the Protection of Purchasing Power, the index of 1er quarter 2023 now stands at 138.61, representing an annual increase of 3.49%. As a reminder, it had increased by 3.50% at 4e quarter 2022.

At 1er in the 2023 quarter, the increase in the benchmark rent index could not exceed 3.5% in metropolitan France. It is therefore 138.61, or an annual increase of 3.49%.

As the increase in the benchmark rent index cannot exceed 2.5 per cent in overseas communities, it stands at 137.27, or +2.49 per cent.

In the Corsican community, the increase in the IRL is capped at 2%, and amounts to 136.60, i.e. an annual increase of 1.99%


Thearticle 12 of law no. 2022-1158 of 16 august 2022 on emergency measures for the protection of purchasing power provides that for the setting of rental benchmarks between 3e quarter of the year 2022 and 2e in the quarter of 2023, the increase in the benchmark rent index shall not exceed:

  • 3.5% in mainland France;
  • 2 % in Corsica;
  • 2.5% overseas.

Rents will not be allowed to increase above these percentages set during the application of the "rent shield" until June 30, 2023.

As far as the Corsican community is concerned, it is theOrder No. R20-2022-10-11-00012 published in the Code of Administrative Acts of the Prefecture of Corsica, which stipulates that the change in the benchmark rent index may not exceed 2% between 3e quarter of 2022 and 2e quarter 2023.


Without the capping measures, the benchmark rent index would be 142.32, an increase of 6.26 per cent year-on-year. The non-capped IRL is given by Insee as an indication and cannot be used in the context of the revision of a dwelling rent.

As a general rule, the rent revision is calculated on the basis of the latest IRL published by INSEE. The IRL sets the annual rent increase ceilings that landlords may charge their tenants when the lease includes an annual rent review clause.

It applies to furnished and unfurnished residential leases.

The IRL is the average change in the consumer price index (CPI) excluding tobacco and rent over the last 12 months.

Please note

The rent of a dwelling subject to the 1948 Law is reassessed each year according to specific rules not related to the IRL.
