How to calculate the revision of a rent according to the annual evolution of the IRL? What is the value of IRL to consider? When can the rent of a unit rented with a residential lease be revised? We explain the rules to know.
The value of theIRL: titleContent is different depending on where it applies:

You can know the previous IRLs and their previous annual changes.
Please note
The IRL is based on the average change in consumer prices excluding tobacco and rent over the last 12 months.
THEIRL: titleContent serves as a basis for revising the rent of an empty rented dwelling or furnished with a residential lease. The annual change in the IRL determines the maximum increase that the owner of the dwelling can apply to the rent for the year.
The IRL to be taken into account is different depending on the type of accommodation:

Private sector housing
The owner (or real estate agency) of a private sector dwelling can review the rent once a year if a clause in the lease provides for it.
Warning
- In metropolitan France, when the lease is signed, renewed or tacitly renewed since 24 august 2022, and it concerns a dwelling classified F or G (classification indicated on the EPD: titleContent), it is forbidden to revise the rent.
- In Guadeloupe, French Guiana, Martinique, Reunion and Mayotte, when the lease is signed, renewed or tacitly renewed since 1er July 2024, and it concerns a dwelling classified F or G (classification indicated on the EPD: titleContent), it is forbidden to revise the rent.
The date of the IRL to be taken into account is the date indicated in the lease. This may be the annual end date of the lease or another date agreed between the owner and the tenant.
If the date of the IRL to be taken into account is not indicated in the lease, the date of the last IRL published by theInsee: titleContent at the time of signing the lease.
Warning
- If a rent supplement applies, the amount of the rent is equal to the total of basic rent and the rent supplement.
- For a furnished dwelling, if the expenses are to be paid at the flat rate, this amount can be revised each year according to the same rules as those of the rent revision.
- For a home governed by the 1948 law or Contracted Anah However, the rules for reviewing the rent are specific.
To calculate the revision of the monthly rent amount, the landlord (or real estate agency) needs the following 3 elements:
- Current monthly rent amount
- IRL for the reference quarter (provided for in the lease or published by theInsee: titleContent at the time of signing the lease)
- IRL for the same quarter of the previous year.
The calculation consists of the following operation:
New rent = current rent x new IRL for the reference quarter of the lease / IRL for the same quarter of the previous year.
Example :
A lease signed in metropolitan France on July 20, 2023, and fixing the monthly rent at €600, may be revised on 20 July 2024.
The last index published on the date of signature of the lease is that of 2e quarter 2023, i.e 140.59.
The new index published on the revision date is that of 2e quarter 2024, i.e 145.17.
July 20, 2024, date of 1re revision of the rent, the new amount of the rent must be calculated as follows: €600 x 145.17 / 140.59 = €619.55.
FYI
The result of the calculation must be rounded to the nearest 2nd decimal place.
To do this calculation, you can use the following simulator:
Social housing (HLM)
Rent is revised every 1er January.
The variation of IRL: titleContent taken into account is that of 2e quarter of the previous year.
The 1er January of year N, to calculate the new rent to be applied, the social landlord needs the following 3 elements:
- Current monthly rent amount
- IRL of 2e quarter of year N-1
- IRL of 2e quarter of year N-2
The calculation consists of the following operation:
New rent = current rent amount x IRL of 2e quarter of year N-1 / IRL of 2e quarter of year N-2
Example :
For a lease signed in metropolitan France on March 9, 2024, fixing the rent at €600, the social landlord can revise the rent for the 1re times the 1er January 2025 (year N).
For this, it needs the following 3 elements:
- The current monthly rent amount, i.e €600
- The IRL of 2e quarter of year N-1, i.e. IRL of 2e quarter 2024, 145.17
- The IRL of 2e quarter of year N-2, i.e. IRL of 2e quarter 2023, 140.59
The calculation is as follows:
New rent = €600 x 145.17 / 140.59 = €619.55.
FYI
The result of the calculation must be rounded to the nearest 2nd decimal place.
To do this calculation, you can use the following simulator:
Calculate the revision of your rent
Please note
If the social landlord has done rehabilitation work, he can revise the rent differently, for a limited time.
The owner (or real estate agency) can apply annual rent review within one year of the date of the revision of the lease.
The rent review does not apply retroactively, but only from the date of the application.
When the one-year period has elapsed, the unapplied revision is lost to the owner.
Example :
If the revision date is March 13, 2025, the landlord can revise the rent until March 12, 2026.
But if the landlord does not request it until June 13, 2025, only rents collected from that date can be revised.
