Electricity-cost calculators for Germany

Use euros, your own tariff, and device-specific operating models—without pretending one national average fits every household.

Billing context

Use the rate that changes with consumption.

Household electricity is sold by competing suppliers and usually combines an energy price with a fixed base charge. Contract, network area, consumption, taxes, and price guarantees affect the result.

How to enter your rate

Enter the Arbeitspreis in euros per kWh from your contract or latest bill. Keep the Grundpreis separate from an appliance-level running-cost calculation.

The energy calculation works without a tariff. Enter your bill's per-kWh rate to convert energy into local cost.

Local calculator

Electric heater

Direct electric heaters consume at the full Arbeitspreis while active, so room heat loss, runtime, supplier contract, and thermostat cycling dominate cost.

Calculate local cost ↗Local calculator

EV charging

EV charging cost depends on the household or mobility tariff, charge timing, battery conditioning, losses, and whether a separate metered rate applies.

WhyThe page exists to answer an operating-cost decision. Advertising never changes a formula, default, or recommendation.
