A household using 997 kWh over the same 91 days, the 4,000 kWh a year we use to compare states, would pay about $482 on this tariff. Yours is about the same.

Uses the Default Market Offer reference price for Ausgrid, 2026-27, including GST. Market offers are often cheaper. Estimates only, not a quote.

How to use the calculator

  1. Choose your state and network

    Your network is printed on your bill as the distributor. In NSW, Victoria and Queensland it changes the price, so pick the right one.

  2. Enter your usage and billing days

    Copy the total kWh and the number of days from your bill. Use the month, quarter or year buttons if you are estimating.

  3. Choose your tariff

    Flat rate works for most bills. Where a regulated time-of-use price exists, switch to time of use and set how much of your power you use in the peak.

  4. Add controlled load and solar

    If your bill has a separate hot water line or a solar credit, enter those under the optional section for a closer match.

How the maths works

Every Australian electricity bill comes down to two charges. The usage charge is the kWh you used multiplied by your rate in cents. The daily supply charge is a fixed amount for every day you are connected, whether you use power or not. Controlled load and solar credits are added or taken off after that.

Worked example: 1,000 kWh over 91 days on the Ausgrid reference price
Usage1,000 kWh × 33.14c$331.37
Daily supply91 days × $1.6623$151.27
Total for the quarter$482.64
Flat rate, prices include GST. Rounded to the nearest cent.

The supply charge is the part people forget. At $1.66 a day it is about $607 a year before any usage, and on the Essential Energy network in regional NSW it is close to $994. A low-usage home can pay a third or more of its bill in supply charges. See our guide to daily supply charges.

Why your bill may not match the estimate

  • You are on a market offer. Most households pay less than the regulated price. Enter your own rates from your bill to match it.
  • Concessions and rebates. These come off after the charges and are not included in the estimate.
  • Estimated reads. If the meter was not read, the bill is a guess that gets corrected later. Our guide to estimated reads explains how.
  • Different billing days. A 92-day bill has one more day of supply than a 91-day bill.

The quick check

Enter your usage and days on the regulated price for your network. If your actual bill is higher than the estimate, you are paying more than the standing offer benchmark and should compare plans.

Calculators for each state

Each state page opens the calculator on that state and explains how bills work there.

Questions about calculating your bill

Multiply the kWh you used by your usage rate, then add the daily supply charge for every day in the billing period. On the Ausgrid reference price, 1,000 kWh at 33.14c is $331.37 and 91 days of supply at $1.66 is $151.27, so the quarter comes to about $483. Take off any solar feed-in credit and concessions.

Look for a section called usage, consumption or your electricity charges. It shows the kWh used, often split into peak, off-peak or controlled load lines, and the dates of the billing period. Add up the kWh across all general usage lines and enter any controlled load separately.

The calculator uses the regulated reference price for your network. Your retailer may charge less on a market offer, add or remove discounts, apply concessions, or bill a different number of days. Estimated meter reads can also make one bill high and the next one low. Enter your own rates from your bill if you want to match it exactly.

Yes. Every rate used is GST inclusive, which is how Australian retailers quote residential prices. The total is what you would see as the amount due before any concession or discount.

It varies by state and household. Priced on each state's regulated tariff, a 1,000 kWh quarter costs about $374 in the NT and $583 in South Australia. Bigger homes, pools, electric heating and EVs push usage well above that. Compare your kWh per day to judge your own bill.

Yes. Open the controlled load and solar section, enter the kWh you exported in the billing period and your feed-in rate. The calculator subtracts the credit from your bill. Use the usage figure for power you bought from the grid, not your total household consumption.

Use whatever is on your bill. Time of use is only available in the calculator where a regulator publishes a single time-of-use rate, such as Victoria, Tasmania and the NT. In NSW, South East Queensland and South Australia each retailer sets its own time-of-use prices.

Usually between 89 and 92 days, depending on when your meter is read. The calculator defaults to 91 days. Check the billing period dates on your bill and enter the exact number, because each extra day adds another daily supply charge.
