Wattage Cost Calculator

Electricity Cost: $

Introduction: Are you curious about how much electricity a particular appliance consumes and what it costs you? The Wattage Cost Calculator is here to help. It allows you to determine the daily electricity cost of any appliance in your home. This handy tool is perfect for budgeting and making energy-efficient choices.

Formula: To calculate the electricity cost, we use the following formula:

Electricity Cost ($) = (Wattage (W) × Hours of Use (h) × Electricity Rate (per kWh)) / 1000

How to Use:

  1. Enter the wattage of your appliance in watts.
  2. Input the number of hours you use the appliance daily.
  3. Provide your electricity rate in dollars per kilowatt-hour (kWh).
  4. Click the “Calculate” button.
  5. The calculator will display the estimated electricity cost per day.

Example: Let’s say you have a 1000-watt space heater, you use it for 6 hours a day, and your electricity rate is $0.12 per kWh. The calculation would be:

Electricity Cost = (1000 W × 6 h × $0.12) / 1000 = $0.72 per day
