AUSTRALIA · ELECTRICITY
Make sense of Australian household electricity costs, including usage rates, supply charges, time-of-use tariffs and the numbers used in HomeBillLab calculators.
What to understand first
Usage rates and supply charges are different
The variable usage rate is normally charged for each kilowatt-hour consumed, while a supply charge is a fixed charge for having the property connected. Appliance running-cost tools should normally use the relevant variable usage rate rather than adding the daily supply charge to one appliance.
Time-of-use plans need the right rate
Some plans apply different rates by time of day or other conditions. If an appliance operates across different tariff periods, separate scenarios can be more useful than hiding the variation inside one blended number.
Your bill is the practical starting point
Electricity prices vary by plan and location. HomeBillLab therefore prefers user-entered tariff data instead of inserting a single fixed “Australian average” into calculators.

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.
