Cost & footprint
The cheapest tariff in year one is rarely the cheapest in year two. This calculator puts both years side by side and shows the consumption at which the ranking flips.
How we calculate
Annual cost is twelve monthly standing charges plus consumption times the unit rate.
New-customer bonuses are attributed to the first year only and removed in the second.
The crossover point between two tariffs is derived analytically from the difference in standing charge and unit rate.
Every tariff is also converted to an effective price per kilowatt hour for direct comparison.
Law & subsidies
Regulation determines the limits and tariffs this calculator works with.
Basic supply carries a two-week notice period. A price increase triggers a special right of termination.
Special contracts usually run twelve or twenty-four months with three months' notice. After the initial term they roll over, but may then be cancelled with at most one month's notice.
A supplier raising prices must give at least six weeks' notice in text form; the special right of termination runs from receipt.
Frequent questions
Anyone chasing the new-customer bonus switches annually. It takes about fifteen minutes and saves many households €150 to €350 a year.
A tariff whose unit rate follows the hourly exchange price. It pays off if you can shift load — with a heat pump, battery or electric car. Without controllable loads the potential is small.
In small households, yes. At 1,200 kWh a year, a €5 monthly difference in standing charge is 5 cents per kilowatt hour — more than most unit rate differences.
All results are model calculations based on your inputs and statistical reference data. They do not replace individual professional planning.

At 3.200 kWh, the standing charge is 11 % of the best tariff's annual cost. The smaller your consumption, the more it decides — and the less the unit rate does.
