Estimate your monthly electric bill from your usage and rate, or find out what a single appliance costs to run. Choose your state to start from its average residential rate, or enter the rate from your own bill for a closer estimate.
Estimate your monthly electric bill
Find this on your bill. A typical U.S. home uses roughly 900 kWh a month.

State rates are average residential prices for July 2026 from the U.S. Energy Information Administration. This is an estimate. Your actual bill depends on your utility, rate plan, taxes and fees. Appliance wattages are typical values, so check the label on yours.
How the calculator works
Your bill is mostly your usage in kilowatt-hours (kWh) multiplied by your rate per kWh, plus any fixed monthly charges and taxes. The state averages in this tool are the U.S. Energy Information Administration’s average residential prices, which already include typical fixed charges. If you type in the rate from your own bill, add your fixed charge separately.
How to find your kWh usage
Look for a usage or meter-reading section on your bill. It lists the kilowatt-hours you used during the billing period. Many utilities also show usage history in your online account.
How appliance cost is calculated
An appliance’s monthly energy is its watts, multiplied by the hours it runs each day and the days it runs each month, divided by 1,000 to convert to kilowatt-hours. Multiply that by your rate to get the cost. Wattage is usually printed on the appliance label.
Ways to lower your electric bill
- Replace frequently used bulbs with LEDs.
- Set heating and cooling to moderate settings when you are away or asleep.
- Unplug or switch off devices that draw power when idle.
- Ask your utility whether it offers time-of-use rates or a budget billing plan.
- Check whether your provider offers assistance programs if you are struggling to pay.
