The household income is one of the basic indicators of the human living standard in the countries or their regions. The indicator of income is very closely connected to the indicator of expenditures, which completes the view of the living standard of households. During the last two decades, there were some important events that have influenced the development of household incomes and expenditures in Slovakia, such as accession of the Slovak Republic into the EU, adoption of the common currency euro or economic crisis as well. In the last years, the net incomes as well as the net expenditures of the Slovak households have increased. According to the results, this trend will continue; however, the net expenditures will increase faster than the net incomes of households. Therefore, we can expect that the savings rate will decrease. On the other hand, the differences of net household income and expenditures among the regions of Slovakia were not eliminated. There is still a high difference of the net household income mainly between the Bratislava region and the Prešov region.
