Question 1

What is CPI?

Accepted Answer

CPI (Consumer Price Index) is an index that measures the change in prices of goods and services consumed by households over time. It is calculated by the Turkish Statistical Institute (TURKSTAT) and is one of the main indicators of inflation. CPI is used to assess price stability in the economy and determine the inflation rate.

Question 2

How often are CPI data updated?

Accepted Answer

CPI data is published monthly by TURKSTAT. Usually, the previous month's data is announced on the 3rd day of the month. The data on this page is automatically retrieved from the TCMB EVDS (Electronic Data Distribution System) API and updated monthly. Index values are shown based on 2003=100.

Question 3

What does 2003=100 base index mean?

Accepted Answer

A 2003=100 base index means that the average value of 2003 is accepted as 100. For example, if the index value is 500, this indicates that prices have increased 5 times compared to 2003. This base year is the reference point of the index and is used to compare changes over time.

Question 4

What is the relationship between CPI and severance pay?

Accepted Answer

CPI plays an important role in severance pay calculations. According to the Labor Law, the severance pay amount can be updated according to the CPI increase rate. This protects employees' severance pay from the effects of inflation. CPI-based updates should be taken into account in severance pay calculations.

Question 5

Where is CPI data obtained from?

CPI data is calculated and published by the Turkish Statistical Institute (TURKSTAT). The data on this page is automatically retrieved from the TCMB (Central Bank of the Republic of Turkey) EVDS (Electronic Data Distribution System) API. EVDS is the official data distribution platform of the TCMB and provides reliable, up-to-date data.

Question 6

What is the difference between monthly change and annual change?

Accepted Answer

Monthly change (%): The percentage change in the CPI value of one month compared to the previous month. Annual change (%): The percentage change in the CPI value of one month compared to the same month of the previous year. For example, the annual change for January 2025 is a comparison of January 2025 with January 2024. Annual change shows a broader perspective of inflation.
