FAQs
Is this my official electricity bill?
No. It is a planning estimate based on the usage and rates you enter. Your supplier’s official bill may include extra tariffs, discounts or time-of-use rates.
What is a standing charge?
A standing charge is a fixed daily amount you pay regardless of usage, covering the cost of supplying your home. The calculator multiplies it by the days in your billing period.
Where do I find my rates?
Your rate per kWh and standing charge are printed on your electricity bill or listed in your supplier’s tariff documents.
Is my data sent anywhere?
No. The estimate is calculated entirely in your browser and never transmits or saves your entries.
