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)
