In this essential, Thomas Rießinger explains the rules of percentage and interest calculation using many examples. The basic terms of interest and percentage calculation and the corresponding formulas are repeated so that they are easy to apply in everyday life. The author applies the percentage calculation to interest rate problems and introduces different types of three-sentence calculation.

This book is a translation of the original German 1 st edition Dreisatz, Prozente und Zinsen by Thomas Rießinger, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2016. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
