Fiksusti guides
Choose an electricity contract for an apartment by comparing it against your actual usage. With lower usage, a monthly standing charge can make up a larger share of the total; as usage rises, the energy rate matters more. Living in an apartment does not by itself tell you how much electricity you use.
Compare contracts using your own consumption ↓Enter your postcode and annual consumption. The comparison uses current product data and estimates total contract costs.
Product details come from open data published by the Finnish Energy Authority’s Sähkönhinta.fi service. Fiksusti syncs the catalogue and filters it by postcode and your choices. We rank results by estimated annual cost using your stated consumption and the product’s energy and monthly charges. Electricity retailers are responsible for product information.
Usage depends on the number of residents, apartment size, appliances, sauna, underfloor heating, hot-water arrangements, working from home and daily habits. Electric heating can also raise consumption considerably. Use your measured annual usage whenever available.
Check the past 12 months on an electricity bill or in your supplier or network operator’s online service. If you are moving or do not yet have a usage history, make an estimate for your own situation and treat it as an estimate. The calculator does not assume a typical apartment usage.
One person in a studio may use a different amount of electricity from several people in a larger apartment. Room count alone does not determine usage: residents, appliances and heating all matter. Results are ranked using the annual usage you enter, not your apartment type.
The monthly standing charge is billed regardless of consumption. Its annual effect is 12 times the monthly fee. At lower usage, this fixed part can represent a larger share of the total. Compare the energy rate too: a low standing charge alone does not make a contract cheapest overall.
The energy rate per kWh is multiplied by the electricity you use. A small rate difference can therefore have a greater effect at higher annual consumption. Do not choose a contract based only on its standing charge or unit rate.
The existing calculator uses the API product data, your annual usage, and supported energy-rate, standing-charge and promotion details. Contracts are ranked by estimated total cost where the available data supports a calculation. The estimate excludes distribution and is not a guarantee of your future bill.
Spot prices change with the market. Suitability depends on how much electricity you use, whether you can shift some usage and how comfortable you are with price changes. Spot pricing is not automatically the best or cheapest option for an apartment.
Fixed-term and open-ended describe contract duration. Fixed-rate and spot-linked describe how the energy price is set. Check the product terms: duration alone does not tell you how the energy rate is calculated.
An apartment may have electric underfloor heating or another significant electric heating load. If you pay for it, do not rely on a general low-use apartment estimate. Find your actual consumption or estimate it for your situation.
This comparison covers electricity supply contracts. Distribution is billed separately under the local network operator’s terms and cannot be switched in the same way as the electricity supplier. Do not confuse distribution charges with a contract’s standing charge.
The suitable option depends on postcode, availability, actual usage, energy rates, standing charges, promotions and pricing model. No single contract is cheapest for every apartment resident. Compare offers using your own details.
