Indices for the construction sector
See the statistics on quarterly cost developments of housing constructions (BYG43) and civil engineering projects (BYG61), yearly price developments for construction of dwellings (PRIS90) and renovation and maintenance work (PRIS91), and monthly statistics on productivity in the construction sector (BYGPRO).
The statistics are used to regulate building contracts and monitor general economic trends.

A price index is used to track relative price changes. The price index measure average price changes between two time periods by comparing the price index in the two periods.

Construction cost index for residential buildings
Most data used in the construction cost index for residential buildings is gathered from other statistics at Statistics Denmark. Prices of materials and equipment are primarily collected from the Price Index for Domestic Supply, from which more than 1000 material prices of approximately 70 representative goods are gathered for use in Construction cost index for residential buildings. Prices of machinery and equipment are also gathered yearly from Molio Prisdata.
Prices of transportation are collected quarterly from the Producer price index for services, from which prices of freight transport by road are used.
The prices of total labor costs are mainly collected from Statistics Denmark's Implicit indices of average earnings. For more information, see the documentation of statistics for Implicit index of average earnings.
The weights used in the construction cost index for residential buildings are based on business accounts from nine actual residential buildings: three one-family houses, three terraced houses and three multi-family houses. The business accounts are collected from contractors of different sizes and geographic location. During the processing of this data, an expert in pricing of residential buildings from Molio has been consulted. The collected information is processed so that each construction part, e.g., the mounting of a concrete wall element, is specified by materials, in this case concrete, by equipment, e.g., building crane, and by type of labor, e.g., concrete element work, that is required, and the associated costs. In cases where the accounts have not been detailed enough for the specific elements Price data from Molio has been applied to estimate the cost shares.

Construction cost indices for civil engineering projects
The data used in Construction cost indices for civil engineering projects are mostly obtained from other statistics produced by Statistics Denmark.
Prices of materials are collected from the Price Index for Domestic Supply, which gathers prices from producers and importers on a monthly basis. Prices of transportation are collected quarterly from the Producer price index for services, from which prices of Freight transport by road are used.
Labor costs are gathered from indices selected from Statistics Denmark's Standardised index of average earnings.
Up to April 2004 material and equipment costs were calculated on the basis of actual prices paid by producers/ importers excl. VAT. This means that the prices used were net of discounts of the actual sale of the materials or equipment. As of April 2004, the prices collected are the importers' purchasing price c.i.f. (i.e. including cost, insurance and freight) excl. taxes and fees, instead of the final sales prices that were collected previously.
The weight basis for this statistic was updated in 2025, with 2021 as base year. It was developed in cooperation with the Danish Road Directorate, Banedanmark and a number of entrepreneurs on the basis of an analysis of road construction work carried out in 2021. The weights reflect the shares of labor costs, material costs, transport costs and equipment costs of the total costs of performing civil-engineering projects. Approximately every fifth year, the weights are evaluated.
The indices for earth works, asphalt works, concrete structures and iron structures are used directly in the calculation of the cost index for construction of roads. The four indices have weights of 45,35 pct. for earth works, 25,24 pct. for asphalt works, 21,36 pct. for concrete structures and 8,05 pct. for iron structures.

Producer price index for construction of dwellings
The Producer Price Index for Construction of Dwellings is calculated on the basis of prices, reported by selected companies engaged in construction of one-family houses. The sample is selected using a top-down approach by turnover. The collected prices cover 30 to 40 pct. of completed free standing one-family houses i Denmark every quarter. Furthermore, the price information is enriched with information from the Danish Buildings and Dwellings Register. Currently, only data on free standing one-family houses are collected. This is due to the fact that construction of one-family houses typically is carried out by a single entrepreneur with one final sales price. Construction of multi-family buildings, however, typically involves several entrepreneurs that may not have the final sales price for the whole building, which complicates the data collection process. Prices are collected for the period when house constructions are completed; not the period when the price is agreed upon.
Producer price index for renovation and maintenance
The Producer price index for renovation and maintenance is calculated on the basis of prices reported by select companies. The sample is selected using a top-down approach, where the largest companies, based on turnover, are selected for price reporting.
Index of production in construction (IPC)
The IPC is based on WTA, which are exclusively based on existing data sources, which are subsequently converted to the concepts used in the WTA.
On the statistics – documentation, sources and method
See the documentation of statistics to learn more:
The construction cost index for residential buildings reflects the evolution of housing construction costs in Denmark. The index is used, among other things, to regulate building contracts. The primary users of this index are construction organizations, entrepreneurs, housing developer, professional craftsmen, solicitors, public institutions and the EU. The construction cost index has been published since the first quarter of 2003 and replaces the former construction cost index.
Additional documentation
The Construction cost indices for civil engineering projects show the trends in prices for construction of civil engineering projects in Denmark. It is used, among other things, for regulation of building contracts, and for following the economic conjuncture in the construction industry. The statistics have been compiled in various forms since 1959, but in its current form the indices for earth work, asphalt work, concrete structures, and iron structures are comparable from 1976 and onwards. The index for roads is comparable from 1996 and onwards.
The purpose of Index for Production in Construction (IPC) is to illustrate the business trends in the sector. These statistics have been compiled since autumn 2014, but is in its current form comparable from January 2000 and onwards.
Producer price index for construction of dwellings demonstrates trends in prices at the first stage of commercial transactions for the construction of free standing one-family houses, i.e. the producer price incl. direct construction costs and profits, but excl. VAT, cost of land and other costs not directly linked to the construction. The statistic is typically used in analyses of price developments in the construction sector. It has been compiled since 2019 with indices dating back to 2015.
The purpose of the Producer price index for renovation and maintenance is to track the development of producer prices of renovation and maintenance tasks performed by Danish construction and craftsman companies. This covers the prices of services incl. the producer's direct costs and their profits, but excl. VAT. The statistics has been produced since 2017 with data for 2014 and onwards. It is used primarily to evaluate price developments in the construction industry, and to regulate prices and contracts.
