Definition of "Nebenkosten"

The Nebenkosten is the amount you pay for utilities (heat, hot water, electricity). You pay your Nebenkosten every month with your rent. This is an estimated amount; you might have to pay more at the end of the year, when you receive your Betriebskostenabrechnung.

The Nebenkosten are added to your cold rent (Kaltmiete). The total amount is called the warm rent (Warmmiete).
