How it is calculated
The basis is the Stromspiegel für Deutschland 2025 (electricity consumption benchmark for Germany). It divides households by number of people, type of home and how hot water is heated into seven consumption classes from A (very low) to G (very high). As the average consumption, the calculator shows the middle of class D.
The costs are consumption × electricity price. Use a price here that includes the standing charge – that is, total costs divided by consumption.
- Classes A and B: a very economical household.
- Classes C to E: normal consumption.
- Classes F and G: it is almost always worth looking for appliances that use a lot of electricity, for example old fridges and freezers, instantaneous water heaters or devices that run all the time.
Worked example: two people in a flat
Two people live in a flat, and their hot water comes from the gas heating. According to the Stromspiegel, class D is between 1,700 and 2,000 kWh a year; as the average consumption, the calculator shows the middle of this class, 1,850 kWh. According to co2online, the average for all two-person households in flats is around 1,900 kWh. At 37 ct/kWh, 1,850 kWh costs around €685 a year.
If the household actually uses 2,600 kWh, it is in class F. The electricity costs are then around €962 a year.
- Average consumption (class D): 1,850 kWh
- Economical (class B) up to: 1,500 kWh
- Very high (class G) above: 3,000 kWh
- Your class at 2,600 kWh: F
Frequently asked questions
How much electricity does a 2-person household use?
In a flat without electric hot water, consumption in the middle class D is 1,700 to 2,000 kWh a year according to the Stromspiegel 2025. In a house and with an instantaneous water heater, it is much higher.
Why does a house use more electricity than a flat?
Houses often have additional appliances such as a heating pump, a chest freezer or garden tools, and the rooms are larger. That is why the Stromspiegel has separate values for houses.
What can I do if my consumption is in class F or G?
First check large consumers such as instantaneous water heaters, old fridges and freezers, tumble dryers and devices that run all the time. The appliance calculator shows you what a single appliance costs. A cheaper tariff lowers your costs further.
Are heat pumps and electric cars included?
No. The Stromspiegel applies to normal household electricity. Electricity for a heat pump or an electric car comes on top; there are separate calculators for these.
