About CPI And Rent Increases

Legal cap
The increase rate may be capped by the legal upper limit for the period (often 25%).
What is CPI
The Consumer Price Index is the official inflation measure published by TurkStat.
Calculation period
Pick the CPI period that matches your contract renewal date.

How Is A Rent Increase Calculated?

New rent = current rent × (1 + applicable rate). If CPI exceeds the legal cap, the tool applies the cap.

Formula

New rent = Current rent × (1 + Applicable rate / 100)

Applicable rate = min(CPI, legal cap)
