EnergyBillMap answers one question: what does it cost to run a home in a given city, and where can you save? Every number is calculated from official open data. We never fill gaps with guesses: if a component has no data, the page says so.
The default home
To make cities comparable we use one standard household: 80 mยฒ, 2 people, 2,500 kWh of electricity a year. You can change all of these in the calculators.
Monthly running cost
Monthly cost (excluding rent) = (electricity use ร electricity price + heating energy ร heating price + water use ร water price) รท 12.
- Electricity: the average household price per kWh including all taxes and fixed charges for the country (Eurostat, band 2,500โ4,999 kWh), the Ofgem price cap for Great Britain, and the average residential price per state for the US (EIA).
- Heating energy: heating degree days of the area ร floor area ร a building factor of 0.04 kWh per mยฒ per degree day. Degree days measure how cold a place is over the year.
- Heating price: gas where gas heating is common; in the Nordic countries we assume a heat pump with an efficiency (COP) of 3, priced with electricity.
- Water and rent are added country by country when official data is available.
Heating degree days
For EU countries we use Eurostat's degree days per NUTS 3 region (average of the last five years). For the UK and the US we use NASA POWER climate data (2001โ2025 average) on a 0.5ยฐ grid and convert it to the Eurostat definition with the ratio measured on European cities that have both. The monthly heating curve on city pages always comes from NASA POWER.
Electricity prices by hour
Hourly prices come from the day-ahead market (SMARD, Bundesnetzagentur) for most European zones, from the PVPC consumer price in Spain, and from the Octopus Agile tariff in Great Britain. Day-ahead prices are wholesale prices: taxes, network charges and supplier margin come on top.
Rankings
Cities are ranked inside each country by monthly running cost, among cities with the same set of available components. Only towns with at least 10,000 inhabitants get their own page.

These are estimates for a standard home. Your bill depends on your contract, your building and your habits.
