How to Use the Wattage Cost Calculator

The calculator is user-friendly and requires just a few inputs:

  1. Appliance Wattage: Enter the wattage of your device. This can usually be found on the appliance label or manual.
  2. Hours Used Per Day: Input the average number of hours the appliance runs each day. Fractional values like 1.5 hours are allowed.
  3. Days Used Per Month: Enter how many days per month the device is in use.
  4. Electricity Rate: Enter your local electricity cost per kWh (default is $0.13/kWh).
  5. Appliance Type: Choose from options like Air Conditioner, Heater, Refrigerator, Washer/Dryer, Computer, TV, or Lighting. Each type has a typical duty cycle for more accurate calculation.
  6. Power Factor: Adjust based on the efficiency of the appliance (1.0 = 100% efficient).
  7. Voltage: Choose between 120V or 240V depending on the appliance.
  8. Calculate: Click the Calculate button to see your appliance’s energy usage and cost estimates.
  9. Reset (Optional): Clear all values using the Reset button to start a new calculation.

Example Calculation

Suppose you want to calculate the cost of running a 1500W space heater for 6 hours a day, 25 days per month, at an electricity rate of $0.14/kWh. The heater has a power factor of 0.90 and uses 240V.

  • Appliance Wattage: 1500W
  • Hours Used Per Day: 6
  • Days Used Per Month: 25
  • Electricity Rate: $0.14/kWh
  • Appliance Type: Space Heater
  • Power Factor: 0.90
  • Voltage: 240V

The calculator provides:

  • Actual Power Draw: 1667 W (1500 ÷ 0.9)
  • Daily Energy Usage: 10.0 kWh
  • Monthly Energy Usage: 250.0 kWh
  • Annual Energy Usage: 3650.0 kWh
  • Hourly Cost: $0.233
  • Daily Cost: $1.40
  • Monthly Cost: $35.00
  • Annual Cost: $511.00
  • Current Draw: 6.95 A

This example shows how much running a single appliance can cost over different periods, helping you plan and save money effectively.
