kuluttajahintaindeksissä

Kuluttajahintaindeksi, often abbreviated as KPI, is a statistical measure used to track the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It is a key indicator of inflation and deflation. The basket typically includes items such as food, housing, transportation, clothing, medical care, recreation, and education.

The index is calculated by comparing the total cost of this fixed basket of goods and services in the current period to its cost in a base period. The difference, expressed as a percentage, represents the inflation rate. For example, if the KPI rises from 100 in the base period to 105 in a subsequent period, it indicates that prices have increased by 5%.

Central banks and governments use the KPI to guide monetary policy decisions, such as setting interest rates, and to inform fiscal policy. It also helps consumers and businesses make informed decisions about their spending and investments. In Finland, Statistics Finland is responsible for calculating and publishing the consumer price index. The index is a crucial tool for understanding economic trends and their impact on everyday life.
