konsumentprisindex

Konsumentprisindex (KPI) is the Swedish consumer price index, a key macroeconomic indicator that measures how prices for a representative basket of goods and services used by households change over time. It is the standard measure of inflation in Sweden and is used to assess the cost of living and the purchasing power of households.

Calculation and methodology: KPI is built from a fixed basket of goods and services reflecting typical household spending. Each item is assigned a weight based on expenditure patterns, and prices are collected monthly from a sample of retail outlets and service providers nationwide. The index is expressed relative to a base year (set to 100). Because consumption patterns evolve, the weights are periodically updated to keep the basket representative. In addition to KPI, statistics offices may publish related measures that adjust for particular components, such as energy or mortgage costs, to suit analytical needs.

Publication and use: KPI is published by Statistics Sweden (Statistiska centralbyrån, SCB). It serves as the official measure of inflation in Sweden, informing monetary policy, wage negotiations, social benefits, and cost-of-living adjustments in contracts and pensions. Analysts also use KPI to study price dynamics across sectors and to compare inflation over time.

Related indicators: A closely watched variant is KPIF, the KPI with a fixed mortgage rate, which isolates price movements excluding changes in housing-related borrowing costs. See also inflation metrics and price indices for broader context.
