Frequently asked questions
How do I calculate the cost to run an appliance?
Multiply the appliance's power in kilowatts (watts ÷ 1,000) by the hours you use it, then by your electricity rate in dollars per kWh. A 1,500-watt space heater run 5 hours a day at the U.S. average of 16.8¢/kWh costs about $1.26 a day, or roughly $38 a month.
How much does electricity cost per kWh?
The U.S. residential average is about 16.8¢ per kWh in 2026, but it ranges from around 10.5¢ in Idaho and Louisiana to about 42¢ in Hawaii. Picking your state in the calculator uses a realistic local rate instead of a generic one.
What uses the most electricity in my home?
Heating and cooling usually top the bill — central AC, electric furnaces, heat pumps, and electric water heaters. Big intermittent loads like clothes dryers, ovens, and EV chargers add up too. Compare any of them in the calculator.
How much does it cost to run a space heater or AC?
A 1,500-watt space heater costs roughly $38 a month at 5 hours a day; central AC often runs $65–$100 a month in summer. Both scale directly with your state's rate — four times more in Hawaii than Idaho.
