Enter your current rent and the 12-month average CPI; calculate the legal maximum rent in seconds under Turkish law (TBK art. 344). If the hike is illegal, we’ll write the objection letter for you.
Under Turkish Code of Obligations art. 344, the annual increase for residential rents cannot exceed the 12-month average CPI of the previous rental year. Whatever current 12-month average TÜİK announces is the legal cap.
No. A hike above the 12-month average CPI is not legal; you don’t have to pay the excess. If the requested new rent exceeds the legal cap, it is an “illegal hike”.
First calculate the legal cap, then notify your landlord of the legal rate in writing. This tool also generates a ready objection letter for an illegal hike. If no agreement is reached, a rent-determination case can be filed at the civil court of peace.
After 5 years the rent may be set by a judge based on comparable rents and the principle of equity, without being limited to CPI. This tool shows the 12-month CPI cap; for 5+ years the court’s discretion applies.
You can confirm the 12-month average CPI from TÜİK’s official inflation data. The tool is pre-filled with the latest rate TÜİK announced; confirming for the current month is recommended.
The legal cap is based on Turkish Code of Obligations art. 344 (12-month average CPI). Confirm the rate with TÜİK. This tool is for guidance only, not legal advice; in a dispute, consult a mediator or lawyer.
