Electricity bill breakdown
See how your annual electricity bill divides between energy, network costs, taxes and VAT.
Start with your own tariff, or apply an official EU country reference price. Every other value is an example you can edit.

How the breakdown is calculated
Annual cost = your annual electricity use × your tariff. Each of the four components is then shown as its share of that total, which is why the four shares must add up to 100%. You supply the shares; the calculator only multiplies them by your annual cost.
Where a country reference comes from
The official reference price is a national household average from Eurostat for annual use of 2,500–4,999 kWh, with taxes included and expressed in EUR. Wattlyze compares your result with the EU-27 average for the same observation period only, because comparing across periods mixes different price levels. A national average is a benchmark, not your bill: households in the same country pay different rates depending on supplier, contract and region.
When your real bill will differ
Standing charges, time-of-use rates and local levies sit outside this model. If your household falls in another consumption band, or shifts demand to a heat pump or an electric car, your average price per kWh changes as well. Use the shares from your own bill wherever you have them.
Questions this result raises
Why must the four shares add up to 100%?
They describe how one bill divides, not four separate charges. The calculator multiplies your annual cost by each share, so a total below or above 100% would describe a bill that cannot exist.
Is the VAT share the same as the VAT rate?
No. It is the VAT amount as a share of what you pay in total, so it is smaller than the statutory rate: VAT applies to part of the bill, not to all of it.
Why does the reference price use 2,500–4,999 kWh?
Eurostat publishes a separate price per kWh for each consumption band. The band 2,500–4,999 kWh is the one Wattlyze imports, so a household in a different band is compared against a different average.
Does the country average replace my own tariff?
It is a comparison point, not a replacement. Supplier, contract length, payment method and region all move the price you pay, so treat the national average as a check on your own figure.
What is the EU-27 figure in the result?
It is the same calculation run at the EU-27 average price for the same observation period, so the difference isolates the price you pay rather than a change in your usage.
