Introduction: In our modern lives, electricity powers almost everything we use, from lighting our homes to running our appliances. With the increasing focus on energy efficiency and cost savings, it’s essential to have a tool that helps you calculate the cost of running your electrical devices. This is where our Power Usage Cost Calculator comes in.
Formula: To estimate your monthly power usage cost, our calculator uses the following formula: Cost = (Wattage x Hours of Usage x 30 x Electricity Rate) / 1000
How to Use: Using the Power Usage Cost Calculator is simple:
- Enter the wattage of your appliance in watts.
- Input the number of hours you use the appliance each day.
- Provide your electricity rate (per kWh).
- Click the “Calculate” button.
The calculator will display the estimated monthly cost of operating your appliance.
Example: Let’s say you have a 1000-watt (1 kW) air conditioner, and you use it for 5 hours a day. Your electricity rate is $0.15 per kWh.
- Wattage: 1000 watts
- Hours: 5 hours
- Rate: $0.15 per kWh
Upon calculation, the estimated monthly cost would be $22.50.
