Kuluttajahintaedun

Kuluttajahintaedun, also known as consumer price index (CPI), is a statistical measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them. Changes in the CPI are used to assess price changes associated with the cost of living. If the CPI increases, each unit of currency buys fewer goods and services; if the CPI decreases, each unit buys more. The CPI is a key indicator of the economy's health and is used by policymakers, businesses, and individuals to make informed decisions. It is typically calculated and published by national statistical agencies. The CPI is often used to adjust wages, pensions, and other benefits for inflation, ensuring that the purchasing power of these payments remains constant over time. It is also used to track changes in the cost of living and to set interest rates. The CPI can be calculated using different methods, such as the Laspeyres or Paasche index, and can be adjusted for seasonal variations. It is an important tool for understanding the economy and making informed decisions about spending, saving, and investing.
