How electricity costs are calculated.
Electricity is billed in kilowatt-hours (kWh). To calculate cost: multiply the appliance wattage by hours of use, divide by 1,000 to get kWh, then multiply by your electricity rate. For example: a 1,500W heater running 8 hours = 12 kWh × $0.12/kWh = $1.44/day.
The average US electricity rate is about $0.12–0.16 per kWh, but varies significantly by state. Check your utility bill for your exact rate.
Frequently asked questions.
What uses the most electricity in a home?
Heating and cooling typically account for 40–50% of home energy use. Water heaters, dryers, and electric ovens are also major consumers. LED lighting and modern appliances use relatively little.
How can I reduce my electricity bill?
Switch to LED bulbs, use a programmable thermostat, unplug devices when not in use, run appliances during off-peak hours, and ensure your home is well-insulated. Even small changes add up over a year.
