Household budget and Nebenkosten for renters in Germany

What Nebenkosten are, how advance payments and the yearly bill work, how to check the bill, and how to keep a household budget that includes them.

Published 2026-10-08; sources checked 2026-10-08

Rent adverts in Germany often show two numbers: Kaltmiete (rent without running costs) and Warmmiete (rent plus the running costs, called Nebenkosten or Betriebskosten). Newcomers are regularly surprised by the second number, and again by a bill a year later. This guide explains how the system works and how to plan for it. It is general information, not legal or tax advice; for your own lease or a dispute, ask a tenants' association, a consumer advice centre or a lawyer.

Nebenkosten, Vorauszahlung, Abrechnung

In a typical lease you pay a monthly advance payment (Vorauszahlung) for running costs on top of the basic rent. Once a year the landlord settles the account (Abrechnung): your advance payments are compared with the costs actually incurred, and the result is either an additional payment (Nachzahlung) or a refund. The consumer advice centres' page on high utility bills describes the bill as containing, among other things, the billing period, the total costs, the allocation keys (how the costs are split between flats) and the deduction of the advance payments you made.

So the advance payment is an estimate, not a fixed price. If energy or other costs rise, the next bill can be higher than you expected.

Your rights when the bill arrives

According to the Verbraucherzentrale (consumer advice centres):

• Tenants have twelve months to object to the settlement ("zwölf Monate"). The centres still advise checking the bill quickly and objecting immediately if you suspect mistakes. Remember that the payment deadline in the bill is a separate matter, so do not assume the objection period delays it.
• You may inspect all invoices and receipts the bill is based on ("sämtliche Rechnungen und Belege"). The centres say a landlord cannot refuse this by citing data protection.

The law behind this is § 556 Abs. 3 of the German Civil Code (BGB), as quoted on dejure.org. The landlord must settle advance payments for running costs annually, as a general rule, the bill must reach the tenant by the end of the twelfth month after the end of the billing period, and the tenant has twelve months after receiving the bill to raise objections; the law makes exceptions, for example where a party is not responsible for the delay. We are not giving legal advice: if you think a bill is late or wrong, ask a consumer advice centre or a tenants' association before you act.

What to look at on the bill

A simple check with the bill on one side and your lease on the other:

1. Is the billing period correct and do the dates match your move-in or move-out?
2. Do the cost types on the bill appear in your lease? Ask if one is unclear.
3. Are your advance payments deducted at the right amount?
4. Compare to last year. A big jump in one line is a good question to ask.
5. Ask to see the receipts if something looks off.

Build the Nebenkosten into your budget

Because the settlement comes once a year, the practical habit is to treat the monthly advance payment as a fixed cost and to keep a separate small reserve, so that a Nachzahlung does not hit a month's budget. Three steps:

• Write down your fixed costs in one list: Kaltmiete, the Nebenkosten advance payment, electricity, internet, insurance.
• Track what you actually spend each month against what you planned.
• Put a small amount aside each month for the possible Nachzahlung, and keep the bill so you can compare next year.

A ready-made workbook

We built an Excel workbook for this: the Haushaltsbuch tracks income, expenses, fixed costs, utility advance payments and savings goals, with a dashboard. It comes as an English and a German file, so you can use the German terms from your lease alongside English labels. It is a tracking tool; it does not check your Nebenkosten bill and it is not tax advice.
