Compare electricity tariffs

Compare two electricity offers side by side – first year with bonuses, second year without, and the total over 24 months.

Your consumption

The consumption from your last annual bill.

Your two offers

Tariff A

Positive for costs, negative for a credit.

For example: bonus only after twelve months of loyalty. The calculator does not assess the condition legally.

Tariff B

Positive for costs, negative for a credit.

For example: bonus only after twelve months of loyalty. The calculator does not assess the condition legally.

How the calculator works

  • Annual cost = consumption × unit price + annual standing charge + one-off costs. First year net = annual cost − bonuses actually applied.
  • Bonuses are applied in the first year only. In the second year the calculator works without instant and new customer bonuses. Whether a bonus is paid depends on the provider’s conditions – the calculator does not check that.
  • The effective price per kWh is the unit price plus the share of the standing charge. It makes tariffs with very different standing charges comparable.
  • The calculator compares only your own entries. It retrieves no tariff database, knows no providers and gives no recommendation.
  • Meter charges, metering point fees, instalments, deposits, third-party switching rewards and price changes after a guarantee expires are not included. Taxes, levies and surcharges are inside the unit price if you enter it that way.
Worked example

3,500 kWh per year. Tariff A: €0.30/kWh, €12 monthly standing charge, €150 instant bonus. Tariff B: €0.28/kWh, €18 monthly standing charge, no bonus. Tariff A costs €1,044.00 in the first year after the bonus and €1,194.00 in the second year. Tariff B costs €1,196.00 in both years. Over 24 months A leads with €2,238.00 against €2,392.00.

Frequently asked questions

Why does the calculator treat the second year separately?

Because instant and new customer bonuses are usually paid only once. A tariff that looks cheap in year one can be more expensive from year two than the alternative. Looking at both years separately makes that visible.

What is the effective price per kWh?

It spreads the standing charge across consumption and adds it to the unit price. That makes tariffs comparable when a low unit price is bought with a high standing charge.

What does the break-even consumption mean?

It is the annual consumption at which both tariffs cost the same without bonuses. Below it the tariff with the lower standing charge is cheaper, above it the one with the lower unit price.

Does the calculator recommend a tariff?

No. It only puts your own entries side by side. It knows no providers, retrieves no tariff database and does not assess bonus conditions legally.

Notes on the defaults

The defaults are freely chosen example values for illustration. They do not come from a tariff database and do not claim to be current market prices.

  • The example values €0.30/kWh and €0.28/kWh with €12 and €18 monthly standing charge only serve to show the calculation. Enter your own offers.
  • For orientation: according to the BDEW electricity price analysis the average household electricity price was 37.0 ct/kWh for new-customer tariffs at 3,500 kWh (data as of 08/2026).
  • Bonuses are often tied to conditions such as a minimum contract term. The calculator applies a bonus only if you enter it, and flags in the result when the advantage comes solely from the bonus.
