Rent increase in France: what percentage depending on your lease’s quarter?
At most +1.57% if your lease uses the IRL of Q3 2026: the latest index published by Insee, on 15 October 2026. With another quarter, the maximum increase is +1.15%, +0.78% or +0.79%.
Key points
A maximum — The increase cannot exceed the change in the IRL over one year.
The lease’s quarter — The one written in the contract; otherwise, that of the latest index published at signing.
F or G: no revision — Lease signed, renewed or rolled over since 24 August 2022 (mainland France).

On a rent of €650, how much more per month?
Lease using the index of Q2 2026
€650 → €657.49
€650 × 148.37 ÷ 146.68 = €657.49, i.e. €7.49 more per month and €89.88 per year.
Depending on the quarter written in the lease, the increase on this rent ranges from €5.05 per month (Q1 2026) to €10.21 (Q3 2026).
Your rent, your quarter
The new rent excluding charges and the monthly increase, with the index set in the lease. No sign-up.
The lease’s quarter or the signing quarter?§
The one the lease sets as the reference date. If the lease sets none, it is the quarter of the latest index published on the signing date.
The revision takes place once a year, on the date set in the lease or, failing that, on each anniversary of the contract. It applies from the request to the tenant.
Does the 3.5% cap still exist?§
Insee attaches it to the indices from Q3 2022 to Q1 2024: 3.5% in mainland France, 2.5% overseas, 2% in Corsica. None of the four indices in the table falls within that period.
