Inflation figures come from UNECE

The inflation figures presented on this page come from UNECE. This UN agency compiles data from official sources, both national and international (Eurostat, IMF, OECD).

You can also use the calculator on the page to estimate future inflation. The calculator estimates future inflation by assuming that the inflation rate of the past year will continue.

The inflation rate (HICP) published by Eurostat does not include owner-occupied housing

It is worth noting that the EU statistical authority Eurostat also publishes its own inflation figures, which are intended for comparing inflation rates in different European countries. These figures may differ significantly from national figures. The difference is due to the costs of owner-occupied housing. Eurostat's inflation does not take into account, for example, changes in house prices or mortgage interest rates.

The Eurostat consumer price index is called HICP (Harmonised indices of consumer prices).

The European Central Bank aims to keep this harmonised consumer price index at around two percent.

Core inflation does not include energy, food, alcohol and tobacco prices

In addition to these inflation figures, core inflation is also measured. It is calculated from the harmonised consumer price index by removing the effect of energy, food, alcohol and tobacco. The prices of these products can fluctuate significantly.

The European Central Bank is interested in the development of core inflation, as it provides a better picture of the direction inflation is heading.

How is inflation calculated from the consumer price index?

When the consumer price index at a certain point in time i2 and the same index a year earlier i1 are known, inflation can be calculated simply as the percentage change in the index:

Inflation% = i2 - i1 i1 × 100 %
