We believe that financial calculations and everyday math should be accessible to everyone — free, easy, and privacy-friendly. All calculations run locally in your browser. No data is transmitted to any server.
Data Sources
All calculations are based on official publications from the German Federal Ministry of Finance (BMF), the Federal Ministry of Labour and Social Affairs (BMAS), the Deutsche Bundesbank, and other official institutions. We update all values at the beginning of each year.
Creator
Calk24.de was created by Konstantin Iakovlev — the developer behind calk.kz (Kazakhstan) and calk-au.com (Australia). Our goal is to make country-specific calculators accessible and free worldwide.
