Frequently Asked Questions
What does this EU energy cost calculator include?
It estimates a monthly electricity total by multiplying monthly kWh by your euro rate per kWh and then adding the standing charge you enter.
Should I include VAT in the electricity rate?
Use the rate format that matches the bill figure you want to compare against. If your bill rate already includes VAT, enter the VAT-inclusive number.
What is a standing charge?
A standing charge is a fixed recurring electricity fee that applies whether or not you use much energy in the month.
Why might the estimate differ from my actual bill?
Actual bills may include taxes, levies, market adjustments, regional fees, and time-of-use pricing that this simplified calculator does not model.
Where should I verify my rates?
Check your utility tariff documents or supplier statements. Verify current rates with the official government source where applicable.
