Calculation of Rent Increases for Offices, Shops, and Residential Properties in 2025

Rent Increase Rates for Residential and Commercial Properties in January 2025

In Turkey, rent increase rates are determined in accordance with Article 344 of the Turkish Code of Obligations, which provides a legal framework for both residential and commercial leases. The rent increase rate effective as of January 2025 is based on the Consumer Price Index (CPI) data announced by the Turkish Statistical Institute (TÜİK).

In December 2024, the twelve-month CPI average was recorded at 58.51%. Therefore, if a rent increase is applied in January 2025, this rate can be used as the legal ceiling.

Rent Increase Rate for Residential Properties

The increase in residential rents is calculated based on the 12-month average CPI. For January 2025, this rate is 58.51%.

Rent Increase Rates for Residential and Commercial Properties in January 2025

Example Calculation:

• Rent for January 2024: 8,000 TL

• Rent increase rate for January 2025: 58.51%

• Maximum allowable rent increase for January 2025:

  
  

  8,000 TL × 58.51% = 4,680.8 TL (increase amount)

  
  

  New rent: 8,000 TL + 4,680.8 TL = 12,680.8 TL

This calculation indicates that a residential rent of 8,000 TL in 2024 can be increased to a maximum of 12,680.8 TL in 2025.

Rent Increase Rate for Commercial Properties

Commercial rents, like residential rents, are calculated based on the 12-month average CPI. For January 2025, this rate is also 58.51%.

Example Calculation:

• Rent for January 2024: 15,000 TL

• Rent increase rate for January 2025: 58.51%

• Maximum allowable rent increase for January 2025:

  
  

  15,000 TL × 58.51% = 8,776.5 TL (increase amount)

  
  

  New rent: 15,000 TL + 8,776.5 TL = 23,776.5 TL

This calculation shows that a commercial rent of 15,000 TL in 2024 can be increased to a maximum of 23,776.5 TL in 2025.

Legal Regulations and Limits

Article 344 of the Turkish Code of Obligations:"Agreements between parties regarding the rent to be applied in renewed rental periods are valid provided that they do not exceed the increase in the consumer price index (CPI) of the previous rental year. This rule applies to residential and roofed commercial leases. If the parties have not reached an agreement on this matter, the rent is determined by the court, not exceeding the CPI increase rate of the previous rental year."

This article aims to ensure the protection of tenants while regulating the rights of landlords within a legal framework. Agreements exceeding this limit are not valid, and rents determined by the courts also cannot surpass this rate.

Conclusion: Fair and Legal Rent Increases in 2025

As of January 2025, rent increases for both residential and commercial properties should be based on the 12-month CPI average of 58.51%. This rate aims to strike a balance between protecting tenants and safeguarding the rights of landlords.

Adhering to legal regulations during rent adjustments ensures long-term cooperation between parties. It is crucial to comply with these legal provisions when renewing rental agreements.
