Consumer prices rose by 1.8 percent in December 2025, compared to the same period the previous year, according to Statistics Finland.

Preliminary data in the Harmonised Index of Consumer Prices suggested that prices increased by 0.4 percent last month, compared to November.

The biggest increases were seen in healthcare costs, which saw a 5.9 year-on-year increase in December.

Food and non-alcoholic drink prices rose by 2.7 percent, compared to December 2024, but such costs fell slightly compared to last November.

Alcohol and tobacco prices went up by 2.3 percent year-on-year, but they did not change compared to November.

The Harmonised Index of Consumer Prices is used as a general measure of inflation, according to the number-crunching agency. However, it does not include costs related to “owner-occupancy, games of chance, interests on consumption and other credits, fire insurance on owner-occupied dwellings, the vehicle tax or fishing and hunting fees”.
