How the estimate works
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity RateFor this tv example: 120 / 1000 x 5 x 0.17 = $0.10 per day.

Streaming devices add a little more
This calculator estimates the TV wattage you enter. If you use a streaming box, game console, soundbar, or receiver, add those devices separately for a full entertainment setup estimate.
How to lower the cost
Lower brightness and enable automatic power saving when the picture still looks good.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
