Bills include the daily supply charge, any recurring fee and, unless you untick it, every discount that depends on how you pay (pay on time, direct debit); one-off credits such as sign-up bonuses are not counted. Prices are in cents; feed-in is what the retailer pays you for solar exports and is not in the bill, which assumes no solar. A plan marked “Not updated since” was last changed by its retailer more than 120 days before our fetch (92 on this network). Plans open only to some households (members, seniors, solar or battery owners, comparison-site customers, wholesale pass-through) are left out unless you include them.

12 plans on this network could not be priced

These are left out of every ranking above. 8 of them have a demand charge, which depends on a household's highest half-hour of use rather than how much it uses, so no annual estimate is fair to them.

How the household is chosen

Each network is priced for three households. Medium is the regulator's reference household: the AER's Default Market Offer 2026–27 usage and daily profile in NSW, south-east Queensland and SA, and the ESC's Victorian Default Offer 2026–27 usage (4,000 kWh) in Victoria. The ACT, Tasmania and regional Queensland have no default offer, so their medium is the AER's 2020 average for the distributor scaled to match the others. Low is half of medium and high is double. Usage is the same every day, so a seasonal price is weighted by the number of days in each season. A household with controlled load (a separately metered hot water system) adds the network's controlled load kWh, priced on the plan's cheapest controlled load rate. No solar export is assumed.

This is reference data worked out from published prices, not advice about which plan to choose. Each estimate assumes a stated household; a real bill depends on the household's own usage. Check a plan with your own usage at Energy Made Easy before you switch.

Each bill here is an estimate for a typical household's usage, worked out from the plan's published prices; your own bill depends on when and how much you use, so check a plan's estimate with your own usage at Energy Made Easy or Victorian Energy Compare, and confirm with the retailer that you can take it (some offer a plan to new customers only without saying so in the data), before you switch.
