How to use our electricity bill calculator
You need to start by looking deciding how many days you want to look at, one day, one week, one year or anything in between.
Next, the calculator needs to know your electricity consumption per day. This can be worked out from your latest electricity bill, or you can use our average estimates below.
The next two pieces of information you will need to get from your bill. This will differ depending on your energy supplier and tariff. Your unit rate is how much you pay for each unit of electricity, your standing charge is a fixed amount you pay per day regardless of how much energy is used.
Once you put all these details in, you will automatically see a breakdown of your total unit charge over the period you set, the total cost of your standing charge and what your overall bill would be for that period of time.
