Electricity Bill to kWh Calculator

Work out roughly how many kilowatt-hours a bill amount represents after the standing charge.

How it is calculated

kWh ≈ (bill ÷ (1 + VAT %) − standing charges) ÷ unit rate. This assumes one average rate; time-of-use plans will differ.

Results are estimates for planning, not bills or professional advice. For generator hookups use a changeover switch installed by a qualified electrician.
