During the periods when rent agreements are renewed, the most critical issue for both tenants and landlords is the legally applicable maximum rent increase rate. This rate is calculated based on the 12-month Consumer Price Index (CPI) average announced by the Turkish Statistical Institute (TurkStat) and is updated monthly. The 12-month CPI average announced by TurkStat for January 2026 was realized as 34.88%. That is, the maximum increase rate that can be applied for those who will renew their lease contracts in January is 34.88%.
How is the Rent Increase Rate Calculated?
With the legal regulation made in 2022, the rent increase rate for residential leases is determined solely based on the 12-month CPI (Consumer Price Index) average. This rate is applied as a legal upper limit in order to both protect tenants from excessive increases and safeguard the rights of landlords. Different regulations may apply to commercial leases; therefore, the legislation should be checked according to the type of contract.
Rent Increase Rate to be Applied for January 2026: 34.88%
The fact that the 12-month CPI average announced by TurkStat is 34.88% means that for those who will renew their lease contracts in January, unless there is a contrary provision in the contract, the rent can be increased by a maximum of this rate. This rate must be applied correctly so that both tenants and landlords can protect their legal rights.
Calculation Example
Current rent amount: 10,000 TL Rent increase rate: 34.88% New rent amount: 10,000 TL x 1.3488 = 13,488 TL
In this example, the rent amount can be set to a maximum of 13,488 TL for the new period. The parties can also mutually agree to apply an increase below this rate.
Legal Details and Things to Consider
- In residential leases, the 12-month CPI average is the legal upper limit; a higher rate cannot be applied.
- There may be different legal regulations for commercial leases; the contract and the legislation must definitely be checked.

- Put all your agreements regarding the rent increase in writing.
- Pay and receive the new rent amount, calculated using the increase rate, with an official bank receipt.
- Do not hesitate to apply to legal authorities in case of a dispute.
