How to check an Australian electricity bill
An electricity bill combines fixed and usage charges across a billing period. A useful check starts by matching the tariff and meter period before estimating individual appliances.

Identify every charge type
The supply charge is generally a fixed daily amount for connection to the network. Usage charges apply to electricity consumed and may use a flat rate, time-of-use periods, demand components or controlled-load rates. Solar exports, concessions and discounts appear as separate credits or adjustments.
A calculator check should multiply each rate by the matching number of days or kilowatt-hours. Combining all usage under one rate can be misleading when the plan has several tariff periods.
Match the billing period and meter data
Check the start and end dates, number of billing days and whether the reading is actual or estimated. Compare opening and closing meter readings where available. A longer billing period or an estimate corrected in a later bill can explain a change that is not caused by appliance use.
Weather, household occupancy and heating or cooling settings can change usage sharply. Compare the same season where possible rather than only the immediately previous bill.
Estimate appliances carefully
An appliance estimate multiplies power in kilowatts by operating hours and the applicable usage rate. Labelled power can represent a maximum rather than continuous consumption, and thermostatically controlled devices cycle on and off. Smart-meter or plug-meter data can provide a better observation.
- Convert watts to kilowatts before multiplying by hours.
- Use the tariff applying when the appliance operates.
- Keep the daily supply charge separate from appliance usage.
- Confirm whether discounts apply before or after particular charges.
Compare plans using annual cost
A discount percentage alone does not establish the cheapest plan. Compare the annual cost using the household's meter data, tariff eligibility and solar exports. Use the government comparison service available for the jurisdiction and read conditions attached to any discount.
