How much does it cost you to use your appliances? Our appliance and electronic energy use calculator allows you to estimate your annual energy use and cost to operate specific products. Use our calculator below to find out.
Energy Calculator
All appliances have a rating which indicates how much energy it uses. This is usually found on the base of the appliance or just inside the door on larger items. This is either written in Watts (W) or Kilowatts (kW). If it is in kW, multiply the figure by 1,000 and then enter into the calculator.
Your statement will tell you what type of tariff you are on. Click here to see where to find this.
You can see some example ratings for typical appliances in the table below.
Dishwasher | 1500 |
Tumble Dryer | 2500 |
Washing Machine | 2500 |
