Abstract
The Act on special solutions related to prevention, counteracting and combating COVID-19 has temporarily modified numerous legal institutions. One of such modifications is the establishment of a new, lower limit of non-interest credit costs for consumer credit agreements. The purpose of the article is to discuss the rules for applying the new limit, in particular in case of consumer credit agreements concluded for a period longer than the period of validity of this limit. Therefore, the article discusses primarily the function of the maximum non-interest credit costs, how this institution is regulated and the rules for calculating and charging those costs.
