When preparing a cost-benefit analysis (CBA) and other economic analyses, it is crucial to calculate with consistent prices: prices that can be compared with each other. For example, if costs are expressed in euros and benefits in Danish kroner, misunderstandings quickly arise: one euro is not worth the same as one Danish krone. The same difference applies to prices in ‘prices excluding product-related taxes and subsidies’ versus prices in ‘market or consumer prices’. In practice, there is a need for flexibility to calculate in both ‘prices excluding product-related taxes and subsidies’ and in ‘market prices’.

This publication presents calculations to convert prices excluding product-related taxes and subsidies into market prices. Based on new calculations, we recommend a factor of 1.162 for this purpose. Using one average factor for product-related taxes and subsidies is a defensible and pragmatic approach and does not make preparing a CBA unnecessarily complicated.
