Turkey Rent Increase Rate December 2025: Official Rate & Calculation

As the end of 2025 approaches, millions of tenants and real estate investors in Turkey await the official announcement regarding the rent increase rate, which is a vital indicator for regulating the relationship between landlord and tenant. at Skyline Real Estate, we provide you with an accurate and direct analysis of the official figures issued by the Turkish Statistical Institute (TÜİK) to clarify the new financial obligations and the rights of all parties.

What is the Official Rent Increase Rate for December 2025?

The Turkish Statistical Institute (TÜİK) has announced the inflation figures for November, based on which the rent increase cap for contracts renewing in December 2025 has been determined.

The Official Rent Increase Rate is: 35.91%

Legally, this rate is based on the twelve-month average of the Consumer Price Index (TÜFE), not just on annual or monthly inflation. It is worth noting that this rate shows a slight decrease compared to November, which recorded 37.15%, reflecting the downward trend in inflation that the Turkish economy has been witnessing recently.

Important note for tenants and landlords: This rate (35.91%) is the "Legal Upper Limit" that the landlord is not entitled to exceed when renewing the contract, unless there is a prior agreement stipulating a lower rate, or in special legal cases for old contracts.

The New Rent Increase Calculation Method (Practical Example)

To avoid any disputes or calculation errors, you can follow the simple formula below to determine the new rent amount accurately. The formula relies on adding the official rate (35.91%) to the current rent value.

Calculation Formula: New Rent = Current Rent + (Current Rent × 0.3591)

Example: If the current rent is 20,000 Turkish Lira, the new rent according to the specified increase rate is as follows:

27,182 = 20,000 + (20,000 × 0.3591)

The End of the 25% Cap: What Does This Mean for Tenants and Landlords?

There is still some ambiguity among foreign tenants regarding the 25% cap that was previously in effect. To clarify the matter:

1. Expiration of the Cap: The law limiting rent increases to 25% officially expired on July 1, 2024.
2. Current Rule: Reverting to Article 344 of the Turkish Code of Obligations, which stipulates that the maximum increase limit is the twelve-month average of the Consumer Price Index (TÜFE) (which is 35.91% for this month).
3. Tenant Rights: The landlord does not have the right to demand an increase exceeding this rate under the pretext of "market price" unless the lease contract has completed 5 full years, at which point they are entitled to file a "Rent Determination Lawsuit" (Kira Tespit Davası).

Understanding these rules protects you from illegal demands and helps you manage lease renewals in Turkey smoothly.
