Cost & footprint

Is switching really worth it?

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

Calculation model

  1. 01

    Annual cost is twelve monthly standing charges plus consumption times the unit rate.

  2. 02

    New-customer bonuses are attributed to the first year only and removed in the second.

  3. 03

    The crossover point between two tariffs is derived analytically from the difference in standing charge and unit rate.

  4. 04

    Every tariff is also converted to an effective price per kilowatt hour for direct comparison.

Good to know

  • A large bonus paired with a high unit rate is almost always the worse deal at high consumption.
  • Price guarantees usually cover only the procurement component, not taxes, levies and grid fees.
  • Below roughly 1,500 kWh the standing charge dominates — there it is worth looking at tariffs without one.

Law & subsidies

What applies in Austria

Regulation determines the limits and tariffs this calculator works with.

Energy communities: the Austrian speciality

Surplus electricity can be passed directly to neighbours, at freely agreed prices and with reduced grid fees.

Grid fee discount
up to 57 % (local level)
Renewable energy community
same grid level
Citizen energy community
nationwide

Austria implemented the EU rules on energy communities far more ambitiously than Germany. An operator can sell surplus to members of the community instead of releasing it at a low market price.

In practice this is the most effective answer to the missing feed-in tariff: instead of three to eleven cents, fifteen to twenty is often achievable within a community — and the buyer still pays less than to a supplier.

Frequent questions

Answered briefly.

How often should I switch supplier?

Anyone chasing the new-customer bonus switches annually. It takes about fifteen minutes and saves many households €150 to €350 a year.

What is a dynamic tariff?

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.

Does the standing charge really matter that much?

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.
