Cost of Electricity per kWh in Australia: Rates, Bill Calculations and Ways to Save
The cost of electricity per kWh in Australia is roughly 24–45 cents as a starting guide for residential flat-rate usage charges, with a daily supply charge added separately. Your location and plan determine the actual rate; time-of-use prices also change throughout the day. This guide explains how to read those charges, calculate what your appliances cost and choose practical ways to reduce the amount you spend on electricity.
Key Takeaways
There is no single residential electricity rate across Australia. Your state, distribution network and electricity plan determine the price you pay per kWh.
A kWh measures energy consumed. Multiply it by your usage rate to calculate the electricity charge.
Daily supply charges remain part of the bill even when you use less grid electricity.
Compare plans using your own annual consumption and usage times, not the lowest advertised rate alone.
Solar self-consumption replaces some grid purchases; storage makes collected energy available for later use.
Battery savings depend on usable energy, charging costs, losses and the tariff you would otherwise pay.
What Does the Cost of Electricity per kWh Mean?
The cost of electricity per kilowatt hour is the price you pay for each unit of energy taken from the grid. Understanding that unit makes it easier to connect the numbers on your bill with the appliances you use at home.
Understanding kW, kWh and Cents per kWh
Kilowatts (kW) measure how much power an appliance draws, while kilowatt-hours (kWh) measure the energy it uses over time. A device drawing 1 kW for one hour consumes 1 kWh. Your power cost per kilowatt hour determines the usage charge: at 30 c/kWh, that hour costs $0.30. Both the appliance’s power draw and how long you use it affect the total.
Finding the Electricity Usage Rate on Your Bill
Find electricity rate details under Usage Rate or Usage Charges on your bill, usually shown in cents or dollars per kWh; 33 c/kWh equals 0.33 Australian dollars per kWh. Daily Supply Charge is the fixed daily connection cost, usually listed in cents or dollars per day. On a time-of-use plan, Peak and Off-Peak rates show the prices for the periods specified by your retailer; shoulder rates may also apply. Solar export credits appear separately. Your usage rate is the price of each kWh purchased, while the total bill divided by kWh used gives an average cost that also includes fixed charges and other bill items.
Electricity Cost per kWh by State in Australia
The table below compares selected residential usage rates across six states, showing how prices differ by distribution area and tariff.
State or Territory | Distribution Area | Indicative Usage Rate (c/kWh) | Tariff Type | Data Source and Date |

Tasmania | TasNetworks | 24.75 | Aurora Tariff 32 | Aurora Energy; 1 July 2026 |
These examples show how location and tariff structure affect your usage rate. Compare your own rate and daily supply charge with the options available where you live. The Australian Government’s electricity pricing guidance explains default offers and directs you to the relevant state or territory comparison services.
Why Do Electricity Rates Vary?
The electricity cost per kWh reflects the cost of supplying your area and the way your retailer prices its plan. Where you live matters, but so do your meter, tariff structure and the hours when you use electricity.
Location, Network Costs and Retailer Pricing
Energy prices per kWh reflect wholesale energy, network delivery, retail services and other regulated costs. Network costs vary across distribution areas, so neighbouring regions may have different rates. Retailers also set different supply charges, discounts and contract terms. Compare a full year of expected costs to see how those differences affect your household.
Single-Rate, Time-of-Use and Other Tariff Structures
A single-rate tariff charges one usage price throughout the day, while time-of-use tariffs apply different prices during peak, shoulder and off-peak periods set by your plan. Controlled-load tariffs cover separately metered or controlled equipment, often hot water. Demand tariffs also charge for your highest measured demand during specified periods, so both the timing of electricity use and the appliances running together can affect your bill.
How to Calculate Your Electricity Costs
Calculate usage charges first, then add the supply charge for the billing period. Keeping those parts separate shows which costs change when you reduce consumption and which remain while your home stays connected. All dollar amounts below are Australian dollars.
Calculate Usage and Supply Charges With a Household Bill Example
For a single-rate plan: estimated bill = energy used (kWh) × usage rate ($/kWh) + daily supply charge × billing days. Consider a 30-day example using 450 kWh at $0.30/kWh, with a $1.20 daily supply charge.
Usage: 450 × $0.30 = $135.00
Supply: 30 × $1.20 = $36.00
Total: $171.00 before any separate fees, discounts or solar credits
This example uses GST-inclusive rates. On time-of-use pricing, calculate each period’s usage charge separately and add the results. Dividing the example’s full $171 bill by 450 kWh gives an effective cost of 38 c/kWh, which includes supply charges and differs from the 30 c/kWh usage rate.
A Simple kWh Cost Calculator for Australian Appliances
For a simple kWh cost calculator in Australia, use energy (kWh) = power (W) ÷ 1,000 × hours of operation. Multiply the result by your usage rate. The examples below assume a constant draw while operating and a rate of $0.30/kWh; they exclude daily supply charges.
Appliance | Daily Energy Use (kWh) | Estimated Daily Cost (AUD) |
60 W fan used for 8 hours | 0.48 | $0.14 |
100 W television used for 4 hours | 0.40 | $0.12 |
2,000 W kettle used for 6 minutes | 0.20 | $0.06 |
1,500 W heater actively drawing for 3 hours | 4.50 | $1.35 |
*Replace those assumptions with your own equipment’s measured consumption and tariff. Energy labels help with appliances that cycle. For heating and cooling, record actual energy use over a representative day instead of multiplying the maximum input by every hour the unit is switched on.
Practical Ways to Reduce Your Electricity Bill
Start with your plan and avoidable consumption, then look at when you use electricity. Once those basics are clear, solar generation and battery storage have a defined job: replacing some of the grid energy you would otherwise buy.
Compare the Total Cost of Electricity Plans
Use a recent bill and your annual usage to compare electricity plans. Include supply charges, usage periods, demand charges and solar credits. A lower usage rate may be offset by a higher daily charge, particularly in a low-consumption home. Check when introductory discounts end and whether any conditions affect the advertised price.
Reduce Wasted Power and Shift Flexible Usage to Cheaper Times
You’ll usually get the clearest results by tackling equipment used often: heating, cooling, hot water and laundry. Close off unused rooms, clean filters and use efficient settings. To save electricity without disrupting your routine, start with one or two habits you can keep, such as washing full loads and switching off unused equipment.
Next, move flexible tasks into your plan’s lower-priced periods. Set appliance timers where suitable and match daytime use to available solar generation. On a flat-rate plan, focus on reducing consumption and using available solar electricity.
Use More Solar Electricity at Home and Understand Export Credits
Run flexible appliances, such as your dishwasher or washing machine, during the day to use more of the electricity your solar panels generate and reduce grid purchases. Solar export credits are the amounts credited to your bill for surplus solar electricity sent to the grid, calculated using your feed-in tariff. When your usage rate is higher than your feed-in tariff, using solar electricity at home generally offers more value per kWh than exporting it. A battery can store surplus daytime generation for evening lighting or other suitable appliances. To estimate the net saving, account for charging and discharging losses and the export credits you would otherwise receive.

FAQs
Do Electricity Rates Include GST?
Australian residential electricity prices are generally displayed including GST, but check the wording on the bill or offer. Some bills show a GST-inclusive total alongside a separate GST breakdown. Use either inclusive or exclusive figures consistently when calculating costs. If a rate already includes GST, don’t add another 10%. Retailer comparisons are easier when every plan uses the same GST basis.
Why Is My Bill Higher Even Though My Electricity Rate Has Not Changed?
Compare the number of billing days and your average daily kWh first. A longer period, seasonal heating or cooling, or a change in how often you’re home can increase the total without a rate rise. Also check for an estimated meter reading, an expired discount or an added fee. With solar, lower generation or exports may reduce credits and leave a larger amount to pay.
Does a Higher Solar Feed-in Tariff Always Mean a Cheaper Plan?
No. A higher feed-in tariff is useful when you export enough electricity to offset any extra supply or usage charges. Compare plans with both your annual grid imports and exports. Check export caps, eligibility conditions and when the higher rate applies. A home that uses most of its solar electricity during the day may gain less from a generous export rate than a regular daytime exporter.
Can Renters Use a Portable Solar Generator to Power Household Devices?
Yes. A portable solar generator can supply compatible plug-in devices without becoming part of the property’s fixed wiring. You’ll need a suitable place for the panels, enough sunlight and safe cable routing. Ask for approval before attaching panels to the building or changing electrical installations. In an apartment, balcony shading and building rules help determine whether regular solar charging is practical.
Can a Solar Generator Reduce Your Electricity Bill in Australia?
Yes. Using solar-generated electricity instead of grid power can lower your bill. The EcoFlow DELTA 3 Plus Solar Generator (PV220W), for example, stores collected solar energy for compatible household devices. Actual savings depend on sunlight, how much collected energy you use, charging and discharging losses, and any export credits you give up. Compare those savings with the equipment cost to judge the value for your household.
