Receiving a power bill and asking the inevitable question of “how does it cost that much!?” is probably a regular activity every quarter for household bill payers.
While the bill is most likely an accurate representation of the electricity used in that quarter, it can help to know what the average electricity bill looks like, and how to compare electricity plan options, to reduce any stress, or even help you switch to a cheaper plan altogether.
In this article, we will:
Use research data from Canstar Blue to understand the average electricity bills across states and territories, household size, and age group.

What impacts electricity bills
While each household will have different needs, and therefore different requirements for electricity, there are two main things that determine the price of your electricity bill.
How much electricity you use: Fewer people means a household will typically use less electricity, but that might not always be the case. If appliances - such as air con, clothes dryers or dishwashers - are not energy efficient, are used a lot, or used at a more expensive time of day to use electricity (if you are on a time of use tariff), then they could end up costing more.
How much you pay for electricity: A great deal on electricity means you’ll pay less for what you use, resulting in lower quarterly bills.
Reducing your electricity bill is about cutting down on your electricity use, but also making sure you’ve got a competitive energy plan.
Many electricity providers will include information with your bill to help you understand your bill more easily. This includes detailing how much electricity you used and when and comparing your usage to customers in your area.
Getting better than average
If your energy bill is close to the average, then you may be reassured. However, while being close to average is good, there could be savings to make by moving closer to the cheaper options available for you.
It’s also worth remembering that average bill prices are based on a number of assumptions about usage, and don't take individual house sizes or usage habits into account.
If you want to save on your energy bill, then it can help to compare prices from other providers offering similar plans. Keep your most recent energy bill available so you can compare more accurately.
There could be a plan that gives you cheaper rates for the same service, which means you could save. If you find a plan that looks right for you, then switching providers is easy and can be done online in a few steps.
Regular review makes for regular savings
Putting in time to do a regular review of your bills can help you to stay organised and stay on the most competitive plan for your household.
Getting a good deal does take a bit of time and effort, but if you want to be better than average, then it could be well worth it.
