TV Electricity Cost Calculator

Estimate your TV’s electricity use and yearly cost, including the effect of screen size and brightness.

Quick answer

A 90 W LED TV watched 5 hours a day uses about 0.45 kWh — around 8¢ a day or $2.30 a month at $0.17/kWh. Larger and brighter screens draw more; check the wattage on the label or in the manual. Compare other devices on the electricity cost calculator.

About the TV Electricity Cost calculator

Modern LED TVs typically draw 50–120 W depending on size, while large 65–75 inch models and HDR content can push that to 150–250 W. Older plasma sets were much hungrier.

Brightness is the biggest factor you control. “Vivid” or store-demo picture modes can use far more power than standard or eco modes. Standby is usually under 1 W on recent sets.

How to use it

  1. Enter the TV’s typical on-mode power from the label or spec sheet.
  2. Enter daily viewing hours.
  3. Enter your electricity price.

The formula

Yearly cost = Watts × Hours × 365 ÷ 1000 × Price

Worked example

A 55 inch LED TV at 90 W, 5 hours a day

  1. 90 × 5 = 450 Wh = 0.45 kWh per day.
  2. At $0.17/kWh: about $2.30 per month.
  3. About $28 per year.

Frequently asked questions

Do bigger TVs use more electricity?

Generally yes — power scales roughly with screen area and brightness. A 75 inch set can use twice as much as a 50 inch one.

Does a gaming console add much?

Yes. Current consoles draw roughly 150–220 W while gaming. Run the calculator again with the console’s wattage and add the two.

Should I unplug my TV at night?

Modern TVs use very little on standby, so the saving is small — usually less than a dollar a year.
