The third-quarter 2026 IRL and the leases it affects
The tool is set to the third quarter of 2026: enter the rent and the area, and it divides by the third quarter of 2025.
Insee’s rent reference index (IRL) for the third quarter of 2026 is 148.06 for mainland France, against 145.77 a year earlier, so 1.57% over twelve months. The notice was published in the Journal officiel on 16 October 2026. Corsica stands at 143.80 and the overseas departments at 145.21, with the same annual change. Two groups of leases now use it. First, every lease whose review clause names the third quarter as reference, whatever its anniversary month. Second, leases that name no quarter and were signed while the third quarter of 2025 was the latest published, that is from its release on 17 October 2025 until the next release in January 2026. For them, anniversaries falling between the third-quarter 2026 release and mid-January 2027 use this value. The figure is slightly below the second-quarter IRL in level, but the annual change is higher, and the annual change is what decides the increase.

An F or G rated home gets nothing from this release if its lease was signed, renewed or rolled over since 24 August 2022 in mainland France, or since 1 July 2024 overseas: the calculator shows a zero increase when you select those ratings and answer yes to the date question. These limits are listed on Service-public.fr, revision of a home’s rent (F13723).
Where the figure comes from
The value is read from Insee series 001515333. The next quarter, the fourth of 2026, is not yet published and is expected in mid-January 2027. A review requested before that date for a lease referring to the fourth quarter cannot be calculated yet. To see every 2026 review month at once, go to IRL quarters in 2026; the longer history is on the IRL page, and the full procedure on rent review in France.
