Tarbijahinnindeksi

Tarbijahinnindeksi, also known as the Consumer Price Index (CPI) in English, is a statistical measure that tracks the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It is widely used to monitor inflation and adjust wages and benefits for changes in the cost of living.

The index is calculated by comparing the prices of a fixed basket of goods and services in different periods. The base period is typically set to 100, and subsequent periods are compared to this base. For example, if the CPI for a given year is 120, it means that the average price level has increased by 20% compared to the base year.

Tarbijahinnindeksi is used by governments, central banks, and businesses to make economic decisions. For instance, it helps in setting monetary policy, adjusting social welfare benefits, and evaluating the effectiveness of economic policies. It is also used by consumers to understand the purchasing power of their money and make informed decisions.

The index is compiled by national statistical offices and can vary slightly between countries due to differences in the goods and services included in the basket, the methodology used, and the geographic coverage. Despite these differences, the CPI is a valuable tool for understanding economic trends and making informed decisions.
