How we calculate it: watts ÷ 1,000 × hours used × electricity price.
Why this helps
Turn watts into dollars.
Appliance labels tell you watts. Power bills tell you kilowatt-hours. We connect the two so you can see the cost in terms that are easier to use.
About the rate
Use your own bill for the best estimate.
The state figure is an average delivered residential price from EIA. Your actual utility rate, fixed charges, taxes, and time-of-use pricing can make your bill different.
