Totals are based on the rolling 12-month spot average (now 6,90 c/kWh)

Totals are estimated using the rolling 12-month average of the realized spot price (currently 6,90 c/kWh) + the supplier's margin and monthly fee. The average updates daily as new spot prices arrive. Actual cost depends on future spot prices and when you use electricity. The calculation uses 6,8996 c/kWh — rounded above. A hand calculation therefore lands a few cents off.

Campaign prices are computed 12-month averages

Discounted prices and monthly fees on campaign rows are computed 12-month averages: the reduced campaign-period price blended with the normal price for the rest of the period.

The base price is not the realized price

The base price is the contract's fixed starting price. The realized price is the base price ± a consumption impact, determined monthly by when electricity is used relative to spot prices — shifting usage to cheap hours can bring the realized price below the base, and vice versa. Example: base 8.35 c/kWh with a monthly impact of −1.20 → you pay 7.15 c/kWh; +1.20 → 9.55 c/kWh.

Campaign prices are averages over the contract term

A campaign row's discounted monthly fee is a computed average over the whole contract term: the campaign period's 0 € combined with the normal fee for the rest.

Lowest base = the lowest base price in its term

Lowest base only marks the lowest starting price. The Estimate column computes the cost (€/mo or €/yr, your choice) from the consumption and impact you enter — it is your own scenario, not a promise of the realized price — and the green cell marks your scenario's cheapest in each term. Switching the unit never changes the order; the same impact applies to every row, so the order only shifts through monthly-fee differences.

Frequently asked questions about comparing electricity contracts

This service compares electricity contracts from Finnish suppliers impartially. The tables show at a glance which contract is cheapest for your consumption – fixed-term contracts (6, 12, 18 and 24 months), spot electricity and consumption-impact contracts. Prices are collected directly from the suppliers' own sites at least twice a day.

How do I find the cheapest electricity contract?

The cheapest contract depends on your annual consumption: with low consumption the monthly fee dominates, with high consumption the energy price (c/kWh) decides. The tables on this page pre-calculate the total cost for different consumption levels, so you can see directly which supplier is cheapest for your usage.

Which is cheaper: a fixed-term contract or spot electricity?

A fixed-term contract locks the price for the whole term, protecting you from price spikes. With spot electricity you pay the realised market price plus the supplier's margin – over the long run it has often been cheaper, but the price varies hourly. The choice depends on whether you want predictability or, on average, a lower but variable price. Tip: the cheapest first year on spot electricity often comes from using several suppliers' introductory offers in a row – many waive the monthly fee for the first months, and since spot contracts are open-ended, switching suppliers is flexible. The campaign badges in the table show which offers are currently active.

How often are the prices updated?

Prices are collected from the suppliers' own websites at least twice a day, morning and evening. The Latest changes section shows the most recent price changes and new campaigns.

What should I look at when comparing electricity contracts?

Always compare the total cost: besides the energy price (c/kWh), the monthly fee (€/month) and campaign discounts matter. A cheap-looking campaign price does not always mean the cheapest contract – the tables on this page average campaigns over the whole contract term, so the figures are comparable.
