How much does electricity cost per month? Detached house and block of flats 2026

How much electricity different homes use

Price statistics use typical consumer profiles. A typical user of a flat consumes about 2 000 kWh a year, a detached house with an electric sauna stove but no electric heating 5 000 kWh, and a detached house with direct electric heating 18 000 kWh. Your own consumption can differ a lot from these.

In Motiva's example calculations, the consumption of a single resident's 50 square metre district-heated apartment is 3 100 kWh a year, including, for example, bathroom floor heating and an electric sauna stove. In a four-person 120 square metre electrically heated detached house, consumption is 18 900 kWh, of which heating accounts for 9 500 kWh. Charging an electric car adds 2 400 kWh a year to consumption in Motiva's example.

Block of flats: about 2,000–3,100 kWh per year
Detached house without electric heating: about 5,000 kWh a year
Electrically heated house: about 18 000–19 000 kWh a year
Home charging of an electric car: about 2 400 kWh more a year (Motiva's example)

What the total price consists of

A monthly bill consists of electricity energy, the grid company's transmission charges, electricity tax and VAT. From 1.4.2026 the electricity tax including the security of supply fee is 2.325 c/kWh excluding VAT, or about 2.92 c/kWh with 25.5% VAT. In addition, both the seller and the grid company usually charge a fixed monthly basic fee.

According to Statistics Finland, households consuming 5,000–15,000 kWh a year paid 17.9 c/kWh for electricity all in all in June 2026. The total price was about 9–10% higher than a year earlier. According to the Energy Authority's statistics, the total price for a 5,000 kWh household on 1.11.2025 was on average 20.86 c/kWh and for an 18,000 kWh electric heater 15.55 c/kWh.

Detached house without electric heating

According to the Energy Authority, at November 2025 prices the electricity bill of a household using 5 000 kWh a year was on average 1 043 € a year. That comes to about 87 € a month. At the June 2026 total price of 17,9 c/kWh the same consumption would cost about 895 € a year, or about 75 € a month.

In such a home, energy, transmission and taxes each account for about a third of the bill, according to an estimate based on Energy Authority statistics. Competitive tendering of electricity energy therefore affects only part of the total.

Electrically heated detached house

According to the Energy Authority, the electricity bill for an electric heater user with annual consumption of 18 000 kWh averaged 2 800 euros a year. Per month that is on average about 233 euros. With high consumption the price per kilowatt hour is lower because basic fees are spread over more kilowatt hours. About 41 % of the bill is energy, 35 % taxes and 24 % transmission.

The average does not, however, tell you about winter bills. Heating is concentrated in the winter months, when spot-price electricity is also often expensive. The average spot price was 13.72 c/kWh excluding VAT in February 2026 and 5.70 c/kWh in September 2026. With VAT the difference is about 10 cents per kilowatt-hour: every 1,000 kWh used in a month cost about €172 in energy alone on a spot contract in February and about €72 in September.

Flat in an apartment block

In an apartment block, heating is usually included in the maintenance charge or rent, so electricity is only used for household appliances, lighting and possibly a sauna. If Motiva's example of 3,100 kWh is priced at the average price of 20.86 c/kWh for a household using 5,000 kWh, the annual bill is about €647, or about €54 per month.

The figure is a lower-bound estimate. With low consumption, fixed basic fees weigh more heavily, so the real price per kilowatt hour is usually higher than with higher consumption. Check the basic fees of your own network company and supplier from your bill or price list.

How to calculate your own monthly price

The most accurate estimate comes from your own figures. Check your annual consumption in Fingrid's Oma Datahub or on your previous bill. Multiply the consumption by the energy price, the network company's transmission fee and the electricity tax, and add the basic fees of both companies. Finally, divide the result by twelve, but reserve more for the winter months if you heat with electricity.

You can find up-to-date spot prices, electricity tax and monthly average prices in Electricity Price Radar. Electricity contracts can be compared on the Energy Authority's sahkonhinta.fi service.

Annual consumption (kWh) × energy price (c/kWh)
+ annual consumption × transmission fee (c/kWh)
+ annual consumption × electricity tax 2,92 c/kWh (incl. VAT)
+ supplier and network company base fees × 12
= annual cost, from which the monthly average is obtained by dividing by 12

Frequently asked questions

How much does electricity cost per month in a detached house?

With electric heating absent (about 5 000 kWh/year), on average about 75–87 euros a month. In an electrically heated house (about 18 000 kWh/year), on average about 233 euros a month, clearly more in winter.

How much does electricity cost in a block of flats?

The consumption of a flat in an apartment block is typically about 2,000–3,100 kWh per year. At average prices that roughly means about €35–55 per month, but base fees can raise the total.

Why is the winter electricity bill so big?

Heating uses the most in winter, and spot-price electricity is then often more expensive. In February 2026 the average spot price was 13,72 c/kWh, in September 5,70 c/kWh (excl. VAT).
