What is Electricity Cost?
An electricity cost calculator estimates how much it costs to run an appliance based on its wattage (power consumption), hours of use per day, and your electricity rate per kilowatt-hour (kWh).
How this calculator works
The calculator converts your appliance's wattage to kilowatts (÷ 1000), multiplies by hours of daily use to get daily kWh consumption, then multiplies by your electricity rate. Quick-select presets include common appliances like air conditioners (2000W), fridges (150W, 24hr), and pool pumps (1500W). Australian electricity rates typically range from $0.25 to $0.40 per kWh depending on your state, retailer, and tariff type. The annual projection helps you identify which appliances cost the most to run.
