Estimates, Not Bills

All cost figures provided by WattCosts are estimates. They are based on average residential electricity rates published by the U.S. Energy Information Administration (EIA) and typical appliance wattage ratings. Your actual electricity costs will differ based on your specific utility plan, rate structure, taxes, fees, and the actual power consumption of your appliances.

Rate Data

State electricity rates shown on this Site represent average residential rates and are updated quarterly from EIA data. Your utility may charge more or less than the state average. Many utilities use tiered pricing, time-of-use rates, demand charges, or seasonal adjustments that are not reflected in our calculations. Check your most recent electricity bill or contact your utility for your exact rate.

Appliance Wattage

The wattage values we use represent typical figures for each appliance category. Your specific appliance may use more or less power depending on its age, model, efficiency rating, settings, and condition. Check the label on your appliance or its owner's manual for the actual wattage rating.

Not Financial or Professional Advice

Nothing on this Site constitutes financial, engineering, or professional energy advice. Do not make significant purchasing, home improvement, or financial decisions based solely on the estimates from our calculators. Consult qualified professionals when appropriate.

Limitation of Liability

WattCosts, its creators, and its contributors shall not be held liable for any decisions made or actions taken based on the information provided on this Site. Use the calculators and content at your own discretion.
