Electricity Cost Calculator
Calculate electricity usage cost
About this calculator
The Electricity Cost Calculator helps you determine how much you're spending on electricity for specific appliances or your entire home. By inputting power consumption, usage hours, and your electricity rate, you can calculate daily, monthly, and annual costs. This tool is essential for budgeting, identifying energy-hungry devices, comparing appliance efficiency, and making informed decisions about energy usage to reduce your electricity bills.
How to use
Enter the power consumption of your appliance in watts or kilowatts, specify how many hours per day it runs, and input your electricity rate per kilowatt-hour (found on your utility bill). The calculator will instantly show your daily, monthly, and yearly electricity costs for that device.
Frequently asked questions
Where can I find my electricity rate?
Check your utility bill for the rate per kWh, or contact your electricity provider. Rates typically range from $0.08 to $0.30 per kWh depending on location.
How do I find my appliance's power consumption?
Look for a label on the appliance showing watts or kilowatts, check the user manual, or use a power meter to measure actual consumption.
Are the calculations accurate for all appliances?
Results are estimates based on constant power usage. Actual costs may vary due to fluctuating consumption, efficiency changes, and variable electricity rates.
