    Key statistical concept
  • The CPI measures the average price change for a constant basket of goods and services purchased by private households for consumption purposes.
  • Types of prices: Prices measured are actual prices to the consumer and include turnover taxes and VAT, taking into account rebates.
  • Price collection methods: Approximatively 600 price collectors collect the prices of the same products in the same shops in a total of 188 municipalities every month. In addition, prices are centrally collected for many types of products, for instance, via the internet or in mail-order catalogues. On the whole, more than 300,000 individual prices are collected every month.
  • Treatment of Rentals for housing: Rentals are included.
  • Treatment of Owner-occupied housing: OOH is included using imputed rent.
  • Treatment of missing prices: An item selected for price monitoring purposes is replaced by another one, if the former is only seldom or no longer sold.


  • Classification(s) used
    COICOP (Classification of Individual Consumption According to Purpose)

    Aggregation and consolidation
  • Elementary aggregates (EAs): Elementary indices are calculated as ratio of unweighted arithmetic mean of prices.
  • Index Formula: The index is calculated using the Laspeyres formula (2010=100) with weights derived from the 2005 household budget survey.


  • Weights
  • Source of weights: Weights derived from the 2005 survey on income and expenditure of approximately 60,000 households.
  • Time period of current weights: Calendar year 2005.
  • Frequency of weight updates: Weights are updated at five-year intervals.
