How to Calculate Appliance Energy Costs
The average US household pays $0.16/kWh. Enter your local rate above to see accurate costs for your area. You can find your rate on your electricity bill — look for the "price per kWh" or "energy charge" line.
The formula is simple: (Watts ÷ 1,000) × Hours per day × 365 days × Rate per kWh = Annual Cost. For example, a 1,500W space heater running 6 hours a day at $0.16/kWh costs about $526 per year.
Electricity rates vary widely by state. Hawaii has the highest rates (~$0.43/kWh) while states like Idaho, Washington, and Wyoming enjoy rates as low as $0.11/kWh. Your actual cost depends on your utility company, rate plan, and time of use.
ENERGY STAR certified appliances use 10-50% less energy than standard models. Over a 10-year lifespan, choosing an efficient appliance can save hundreds or even thousands of dollars in electricity costs.
