Energy Cost Estimator
Take control of your electricity expenses with our detailed energy cost estimator. Understanding how much energy your appliances and devices consume is the first step toward reducing your utility bills and minimizing your environmental impact. This calculator helps you estimate the cost of running common household appliances based on their wattage, daily usage hours, and your local electricity rate. Whether you're trying to identify energy-hungry devices, comparing the efficiency of different appliances, or simply budgeting your monthly electricity expenses, our tool provides clear insights into where your energy dollars are going. Input the wattage and usage patterns of your refrigerator, air conditioner, water heater, television, computer, and other devices to see detailed breakdowns of daily, monthly, and annual costs. Armed with this knowledge, you can make informed decisions about when to use high-consumption appliances, which devices to upgrade to energy-efficient models, and how to adjust your habits to save money while reducing your carbon footprint.

Frequently Asked Questions
How do I calculate my electricity costs?
To calculate electricity costs, multiply appliance wattage by hours used, divide by 1,000 to get kWh, then multiply by your electricity rate (cents per kWh). Formula: (Watts × Hours ÷ 1,000) × Rate = Daily cost. Our calculator automates this process for accurate estimates.
What is a kilowatt-hour (kWh)?
A kilowatt-hour (kWh) is a unit of energy equal to using 1,000 watts for one hour. For example, a 100-watt light bulb running for 10 hours uses 1 kWh. Utility companies charge by the kWh, typically ranging from $0.10 to $0.30 per kWh depending on location.
What appliances use the most electricity?
The biggest electricity consumers are HVAC systems (heating/cooling), water heaters, refrigerators, washers and dryers, electric ovens, and dishwashers. These appliances can account for 60-80% of home energy usage. Identifying high-consumption devices helps target energy-saving efforts.
How can I reduce my electricity bill?
Reduce electricity costs by using LED bulbs, adjusting thermostat settings (68°F winter, 78°F summer), unplugging devices when not in use, using energy-efficient appliances, running dishwashers and laundry during off-peak hours, and improving home insulation.
What is the average electricity cost per month?
The average U.S. household electricity bill is around $120-$140 per month, or about $1,500 annually. Actual costs vary widely based on location, home size, climate, number of occupants, and appliance efficiency. Use our calculator to estimate your specific costs.
