Costs
What does your tariff really cost? From consumption, unit price and standing charge, the calculator works out your annual costs, the monthly amount and your average price per kilowatt hour.

Annual costs = annual consumption × unit price + 12 × standing charge per month. The average price is the result divided by consumption – it includes the standing charge and is therefore higher than the unit price.
For comparison, the calculator shows the 2026 average price according to BDEW: 37.0 ct/kWh for electricity (household using 3,500 kWh) and 11.93 ct/kWh for gas (single-family house using 20,000 kWh). With lower consumption, the standing charge has a bigger effect; a higher average price is then normal.
A household uses 2,500 kWh of electricity. The tariff costs 33 ct/kWh and a standing charge of €13 a month. The unit price comes to €825, the standing charge to €156 – a total of €981 a year or €81.75 a month. The average price is 39.24 ct/kWh.
You pay the unit price for every kilowatt hour you use. You pay the standing charge regardless of consumption, for example for the meter and billing.
On your annual bill or in your contract. Look for gross prices (including VAT) and check whether the standing charge is given per month or per year.
Not always. With low consumption, a tariff with a higher unit price and a low standing charge can be cheaper. So always compare the annual costs.
Compare your current tariff with a new offer. The calculator separates the first year with the bonus from the second year without the bonus – so you can see whether an offer is cheaper in the long term.
