Electricity Bill Calculator (Australia)
Estimate your power bill per quarter, month and year from your usage and your plan's rates.
Starting rates are typical 2026–27 single-rate prices in each state, including GST. Plans vary a lot, so enter the rates from your own bill for the most accurate figure.

How your electricity bill is worked out
Most Australian electricity bills have two parts:
- Usage charge: the number of kilowatt-hours (kWh) you use, multiplied by your usage rate in cents per kWh.
- Daily supply charge: a fixed amount for every day you're connected, whether you use any power or not. It covers the poles, wires and meter.
So the formula is: (kWh used × usage rate) + (days × supply charge), less any discounts and solar feed-in credits. For example, 15 kWh a day at 29c/kWh with a $1.15 daily supply charge costs about $4.35 + $1.15 = $5.50 a day, or roughly $500 a quarter.
Typical electricity rates by state (2026–27)
These are typical single-rate prices for homes without solar, including GST. Your plan could be higher or lower.
| State | Usage (per kWh) | Supply (per day) |
|---|---|---|
| New South Wales | 34c | $1.10 |
| Victoria | 29c | $1.15 |
| Queensland | 31c | $1.15 |
| South Australia | 41c | $1.15 |
| Western Australia | 32c | $1.15 |
| Tasmania | 30c | $1.20 |
| ACT | 28c | $1.00 |
| Northern Territory | 28c | $0.75 |
Prices in most states fell slightly from 1 July 2026, according to the regulators' default offers. South Australia was the exception, with a small rise.
How much electricity does an average home use?
A typical Australian household uses about 10–20 kWh a day. Usage is higher with electric heating or cooling, a pool, an electric car or a large family, and lower in small apartments or homes with gas heating and hot water. Your bill shows your average daily use, usually as a graph by quarter.
Ways to lower your bill
- Compare plans. Retailers' rates differ a lot, and staying on an old plan often costs more. The government's free Energy Made Easy site (or Victorian Energy Compare in Victoria) lists every plan in your area.
- Check your tariff type. On a time-of-use plan, running the dishwasher, washing machine and pool pump outside peak hours can save money.
- Heat and cool efficiently. A reverse-cycle air conditioner is usually far cheaper to run than a fan or oil heater. Use our appliance running cost calculator to compare.
- Consider solar. See our solar payback calculator for how long panels take to pay for themselves.
Frequently asked questions
What is the average electricity bill in Australia?
Many households pay around $350–$600 a quarter, depending on their state, plan and how much power they use. Larger homes with electric heating or a pool can pay much more.
What is a daily supply charge?
It's a fixed fee for each day your home is connected to the grid, typically around $0.75–$1.30 a day in 2026–27. You pay it even if you use no electricity.
How do I find my usage on my bill?
Look for your total kWh for the billing period, or your average daily usage. Divide the total kWh by the number of days in the bill to get kWh per day.
Do the rates include GST?
Yes. The rates in this calculator include GST, as do the rates shown on most household bills.
