AUSTRALIA · APPLIANCES
Turn appliance power, kilowatt-hours, usage time and electricity tariffs into practical running-cost estimates for Australian households.
The basic appliance cost relationship
Electricity use depends on electrical power and operating time. Running cost then depends on the kilowatt-hours used and the variable electricity rate. This simple relationship is useful for many household devices when the input power is representative.
Rated power is not always average power
Some appliances cycle, modulate, enter standby or change power during operation. A measured or labelled energy-use figure can sometimes be more representative than multiplying a maximum rated input by every hour of use.
Use realistic usage patterns
Small assumptions can compound across a week or year. Estimate how often the appliance actually runs, then compare scenarios instead of treating one estimate as a guaranteed future bill.

Appliance Running Cost Calculator
Estimate appliance electricity cost from watts and usage time, or use annual kWh from an Energy Rating Label.
How HomeBillLab approaches this topic
We separate the numbers you can calculate from the assumptions that can change the result. Where a tariff, product label, official program or property-specific detail gives a better input, we prefer that information over a hidden national-average assumption.
See the HomeBillLab Methodology and Sources for how we document calculations and references.
