Germany started with a general minimum wage of EUR 8,5 per hour in 2015. Working 40 hours weekly results to EUR 1.473 (8,5 x 40 x13/3). To figure minimum monthly payment when working less than 40 hours weekly put the weekly hours instead of “40”. E. g. 25 hours: 8,5 x 25 x 13/3 = 921.
In sensitive industries such as constructing, cleaning or gastronomy the exact working times need to be documented. The same applies for minijobs with monthly payments of no more than EUR 450.
