Turkey Rent Increase Calculator
Your rent increase cannot exceed the twelve-month average change in the consumer price index (Turkish Code of Obligations, art. 344). Enter the month your lease renews and the tool applies the correct official rate.
Quick answer
A lease renewing in September 2026 can be increased by up to 31.79%. That figure is the twelve-month average change in the consumer price index published by TurkStat, and under article 344 of the Turkish Code of Obligations it is the ceiling on any increase.
The maths is simple: current rent × rate ÷ 100 = the increase. A rent of 20,000 TL rises by 6,358 TL to 26,358 TL. Which rate applies depends on the month your lease renews, and it changes every month.
Two things catch people out. The rate comes from the month before your renewal month. And if your lease has run for more than five years, the ceiling no longer applies, comparable rents come into it too.
Current ceiling
September 2026 renewals · 31.79%
This applies to leases that renew in September. If yours renews in a different month, find your month in the table below.
This is the single most common mistake, and it is worth being precise about. The ceiling for your renewal is not the figure for your renewal month. It is the figure published for the month before it.
An example. Say your lease renews in April 2026. The ceiling is set by the data TurkStat published at the beginning of April, which is the March 2026 twelve-month CPI average is 32.82%. The April figure does not exist yet when your renewal falls due, which is exactly why the previous month is used.
The law does not use the annual inflation figure you hear on the news. It uses the twelve-month average change in the consumer price index, which is a different number and is usually lower. If a landlord quotes you the headline inflation rate, they are quoting the wrong figure.
The 25% cap is gone. Between 11 June 2022 and 1 July 2024 residential rent increases were capped at 25%. That measure was not extended. For any renewal after that date including every row in the table above the only ceiling is the twelve-month CPI average. Pages still saying "the cap is 25%" are out of date.

The Consumer Price Index (CPI) is a key economic indicator that measures the average change over time in the prices paid by consumers for goods and services.

Unless there is a different clause in the lease agreement, landlords in Turkey cannot arbitrarily raise rent beyond this cap. The goal is to protect tenants, especially foreign tenants and expats, from unfair and unpredictable rent hikes.
In 2026, the rent increase cap Turkey calculator is especially useful for identifying whether a proposed increase is lawful or excessive. If the new rent exceeds the calculated limit based on CPI, it may be considered legally excessive, and the tenant has the right to contest it in court.

In Turkey, lease renewal directly affects rent increase, as it provides the landlord an opportunity to revise the rent based on the latest economic indicators, primarily the Consumer Price Index (CPI). According to Turkish law, when a lease term ends and is renewed, any rent adjustment must still comply with the legal rent increase cap, which is tied to the 12-month average CPI.

After five years the rule changes
If your lease has run longer than five years, or is renewed after the fifth year, the increase is no longer capped by CPI.
At that point a judge sets the rent on equitable grounds, taking into account the twelve-month CPI average, the condition of the property and comparable rents in the area. In practice that means the rent can be moved towards the market rate. This is the point at which a long-standing tenant on a low rent is most exposed, and it is worth taking advice before the fifth year is up rather than after.
According to Turkish rental law, rent can be increased once every 12 months at the time of lease renewal. This applies to both Turkish citizens and foreign tenants renting property in Turkey. Regardless of market changes or inflation, landlords are legally allowed to raise rent only once per year, and even then, only within the limits set by the 12-month average Consumer Price Index (CPI).

This rule applies regardless of whether you’re a local tenant or a foreigner. For expats, this is a crucial protection that helps prevent sudden rent hikes. If your landlord tries to raise your rent mid-lease, you can legally object. You should first verify the legality of the proposed increase using a turkey rent increase calculator.
In cases where the lease hasn’t expired, any attempt by a landlord to adjust the rent is typically considered unlawful. You can also reference the turkey rental increase calculator online or turkey rent adjustment calculator for foreigners to determine your rights in English.
To sum up: mid-lease rent increases are not allowed in Turkey. Use trusted tools like the expat rent increase calculator Turkey or online rent increase tool Turkey to stay informed and legally protected.
An increase has to be notified in writing. It does not take effect on its own. The landlord must tell you and the notice has to reach you. A rent rise mentioned in passing is very hard to prove later, which is why a notary’s notice is the safe route. If a landlord says nothing for months and then asks for the whole backdated difference in one go, that demand is open to challenge, get the file looked at before you pay it.
Yes, a landlord in Turkey can set a new rental price when signing a lease with a new tenant. Turkish rent control laws, including CPI-based limits, primarily apply to ongoing leases and annual renewals. However, when a property becomes vacant and is rented to a new tenant, the landlord has the freedom to determine the initial rent amount within the boundaries of good faith and general legal principles.
That said, it’s still essential for new tenants, especially expats unfamiliar with local norms, to evaluate whether the proposed rent is fair and in line with market standards. While the turkey rent increase calculator and turkey rental increase calculator online focus on current tenants, tools like the turkey landlord rent hike tool English and compute rent adjustment Turkey expat can help foreigners understand reasonable pricing before signing a lease.
Understanding how to calculate rent increase in Turkey becomes important when your lease renews after the first year. At that point, any increase must follow the annual rent increase formula Turkey law outlines, often based on CPI averages. Using the turkey cpi rent increase calculator or rent increase calculator Turkey expats ensures compliance.
In summary, landlords are legally allowed to raise rent for new tenants, but foreign renters should research market averages and use online tools like the turkey lease renewal rent calculator and turkey annual rental increase calculator English to ensure they’re entering into a fair agreement from the start.
