Online Electricity Calculator
Stromrechner Online - Kostenloser Vergleich
Calculate your electricity costs and find cheaper tariffs. Easy-to-use tool for expats and newcomers in Germany.
What is a Stromrechner?
A Stromrechner (electricity calculator) is a free online tool that helps you compare electricity prices from different providers. Simply enter your postcode and annual consumption to see all available tariffs sorted by price.
For expats and newcomers, this tool is especially valuable. Germany's electricity market is liberalized, meaning you can choose from 200+ providers. Many newcomers unknowingly pay 20-40% more by staying with the default provider (Grundversorger).

Common Questions
Häufige Fragen zum Stromrechner
Is the electricity calculator really free?
Yes, 100% free! There are no costs, no obligations, and no hidden fees. You can compare prices as often as you like. Even switching providers through the calculator is free - we earn commission from providers, not from you.
Where do I find my annual consumption?
Check your last electricity bill (Stromrechnung) - look for "Jahresverbrauch" or "Verbrauch in kWh". If you're new to Germany or don't have a bill yet, use these estimates: 1 person ≈ 1,500 kWh, 2 persons ≈ 2,500 kWh, 3 persons ≈ 3,500 kWh, 4+ persons ≈ 4,500 kWh.
Are the prices shown final?
Yes, prices are binding. The calculator shows real-time prices directly from providers. The annual cost shown includes all fees (kWh price + base fee). Bonuses are also included in the first-year calculation. No hidden costs.
Can I switch directly through the calculator?
Yes! After comparing, click on your preferred tariff to start the online switch. You'll need your meter number (Zählernummer) from your current bill. The entire process takes 5-10 minutes. Your new provider handles canceling your old contract.
Do I need to speak German to use this?
No German required! The calculator interface is straightforward. You only need to enter numbers (postcode and kWh). Results show prices clearly. Many providers also offer English customer support.
