Finnish news portal Yle.fi with reference to the December data from the statistical service of EU Eurostat Finland is the most expensive country in the Eurozone. The research is made on the base of comparing prices for food, clothes and services and it turned out that they are the highest in Eurozone.

For example, for the last ten years the prices for food in Finland grew faster than the average in Europe.
The same situation is with the consumer goods and clothing prices -  if an average European customer gets the shoes for about €100, Finnish customer will pay €121 for the same pair of shoes.
So, it turns out that to have the same purchasing power, the Finns need to get 20% higher salary than the average EU consumer.
