About the CPI Data
Monthly and annual changes in the Consumer Price Index (CPI) published by TurkStat every month. Monthly rates come automatically from our data provider. The annual rate is shown only when the official TurkStat figure can be captured automatically; it is never derived from the monthly rates.
Frequently Asked Questions

According to the TurkStat national data release calendar, October 2026 CPI will be published on November 03, 2026 at 10:00 Istanbul time (UTC+3). Release dates do not fall on the same day every month.
What is the latest inflation rate?
Annual CPI for September 2026 came in at 29.73% and monthly CPI at 1.84%.
How is annual inflation calculated?
TurkStat computes annual inflation from index levels: this month’s CPI index is divided by the index for the same month a year earlier, minus 1. The result compounds the monthly changes rather than adding them; for example, 3% every month is not 36% a year but roughly 42.6%.
What is CPI?
The Consumer Price Index measures the price level of a fixed basket of goods and services consumed by households. Basket weights come from household budget surveys, so food, transport, housing and clothing carry different weights.
How does inflation affect investment returns?
Real return is the nominal return adjusted for inflation: (1 + nominal) / (1 + inflation) − 1. When deposit, fund or stock returns fall short of inflation, purchasing power shrinks, so returns should always be judged against inflation.
