  1. Enter the Power Consumption of your appliance and select Watts (W) or Kilowatts (kW).
  2. Enter the Usage Time in hours per day.
  3. Enter your local Electricity Rate (price per kWh). You can usually find this on your utility bill.
  4. The calculator will display the estimated daily, monthly (30 days), and yearly cost.

Kilowatts (kW) = Watts ÷ 1000
Daily Cost = Power (kW) × Time (hours) × Rate ($/kWh)
Monthly Cost = Daily Cost × 30
Yearly Cost = Daily Cost × 365

Wondering how much that space heater, air conditioner, or gaming PC is really costing you? An electricity cost calculator helps you estimate the running costs of any home appliance. By calculating the power consumption in kilowatts (kW) and multiplying it by your utility provider's rate, you can make informed decisions to save energy and lower your electric bills. You can find out more about how energy consumption works in the Wikipedia article on Electric Power.
