Electricity Cost Calculator
Running cost of any appliance
Curious what an appliance costs to run? Enter its wattage, how long it runs each day and your electricity rate to see the monthly and yearly cost.
Finding the wattage
Check the label or manual for watts (W). Running cost is watts ÷ 1000 × hours × rate. Always-on devices (fridges, pumps, space heaters) add up fast — this is a great way to hunt down energy hogs.
