The eagerly awaited announcement has arrived for millions of people with rental housing or workplaces.
The November 2025 rent increase rate has been determined! With TÜİK’s announcement of October inflation figures, the legal increase rate that can be applied to rents this month has also become clear.
What is the November 2025 Rent Increase Rate?
According to data from the Turkish Statistical Institute (TÜİK):
October 2025 annual inflation rate: %32.87
12-month average CPI (rate used as basis for rent increase): % 37.15
With TÜİK data, the November 2025 rent increase rate has been announced. The legal increase rate for homes and workplaces became % 37.15. Accordingly, in rent contracts to be renewed in November 2025, landlords will be able to make an increase of a maximum of % 37.15. This rate is valid for both residential rents and workplace rents.
Important Note: Landlords can make an increase below this rate, but an increase above it is not legally valid.
Rent Increase Calculation (November 2025)
Formula: New rent = Old rent + (Old rent × %37.15)
Examples:
| Current Rent (TL) | Increase Rate | New Rent (TL) |
|---|---|---|
| 20.000 | % 37.15 | 27.430 TL |
| 30.000 | % 37.15 | 41.145 TL |
This method is valid for all lease agreements to be renewed in the November 2025 period.
How Is Rent Increase Determined?
The rent increase rate is calculated based on the 12-month average of CPI announced monthly by TURKSTAT, according to the Turkish Code of Obligations and current regulations.
The 25% upper limit applied during the 2022-2024 period has now ended; therefore, rent increases in 2025 are once again tied to the CPI average.
Landlords can only implement increases provided they do not exceed the 12-month average of CPI.
Even if there are provisions like “CPI + X%” in the contract, the total rate cannot exceed this limit.
