A TV draws about 90 watts, or 0.09 kWh per hour. Enter your hours and electricity rate below for the exact cost per day, month and year.
Wattage is pre-filled with a typical value for a TV; change any field for your own device, usage and rate. Cost uses your rate × kWh — a US-average placeholder rate of $0.17/kWh is shown; enter your own from your bill for an accurate figure.
A TV draws about 90 watts while running. Energy is billed in kilowatt-hours (kWh), and one kWh is 1000 watts for one hour — so a TV uses 90 ÷ 1000 = 0.09 kWh for every hour it is on. Multiply that by the hours you use it and by your rate per kWh to get the cost. The calculator above does it live; change the wattage if your model differs. Kept up every day of the year at 5 hours a day, that is about 164 kWh — roughly $27.92 at the $0.17/kWh placeholder rate used here.
Screen size drives this more than panel technology does. On ENERGY STAR's certified-television list, median on-mode draw is about 84 W at 44–55 inches, 119 W at 56–65 inches, 141 W at 66–75 inches and 170 W at 76–85 inches; no certified OLED set exceeds 215 W, and the highest-drawing certified set of any type is 344 W. So 90 W fits a typical 55-inch set, and the figure scales with the diagonal rather than with the panel type.
Wattage moves with size, age and model, so treat 90 W as a mid-range starting point rather than a fixed number — the rating plate on your own appliance, or its ENERGY STAR listing, gives the figure to type in. The rate matters just as much: the US Energy Information Administration publishes current average residential prices by state, and the figure on your own bill is better still. This LK Forge calculator recomputes every result as you type.
Two levers change the bill: hours of use and your rate per kWh. Running high-wattage devices less, or shifting them to off-peak hours on a time-of-use plan, has the biggest effect. For a whole-home estimate or to compare devices, use the full electricity bill & appliance calculator.
