This is a regulation that protects you as a customer. The aim is to improve the comparability of offers. Specifically, it concerns ensuring that offers and loan agreements include all costs that are relevant: regulation for consumer protection. To ensure better comparability, banks are obliged by the Price Indication Regulation (PAngV) to list all relevant costs, prices, and effective interest rates in offers and loan agreements.
In practice, there is, for example, the rule that the effective annual interest rate must also take into account the interest for the period after the first contract. Normally, there is still a certain residual debt open, which must then be continued with a new interest rate. Nobody knows this rate today. In the Price Indication Regulation, there is no rule for this assumption either. Unfortunately, this leads to banks calculating differently, and the desired comparability is lost.
We are happy to help you compare different offers transparently.
