What does an LED television cost to run?

A 55-inch 4K set, five hours a day, out-of-the-box brightness. At the US average rate of 18.34¢ per kilowatt-hour that is $31 a year.

Why this is lower than the number you will see elsewhere

Almost every published answer to this question multiplies the rating on the label by the hours the appliance is switched on. For an LED television that gives 164 kWh a year, or $30.

Backlight draw is steady for a given brightness setting.

Nameplate × hours — the usual answer164 kWh$30
What it actually draws171 kWh$31

The arithmetic, step by step

Nothing here is hidden, so you can check it or change it. Working in the order the formula runs:

  1. 90 W — what it draws while it is actually drawing. This is the rating on the plate.
  2. × 100% — the share of its in-service time it is really pulling that. Backlight draw is steady for a given brightness setting.
    That gives 90 W averaged across the hours it is on.
  3. × 5 hours a day × 365 days — A 55-inch 4K set, five hours a day, out-of-the-box brightness.
    90 × 5 × 365 ÷ 1,000 = 164 kWh a year.
  4. + standby — 1 W for the other 19.0 hours a day, which is 6.9 kWh a year. People leave this out and it is not always small.
  5. × 18.34¢ — the US average residential rate for June 2026.
    171 kWh × 18.34¢ = $31 a year.

Change any assumption in the calculator above and every figure on this page moves with it. The two that matter most are your rate, which varies 4× across the country, and the hours — the duty cycle is a property of the appliance, but the hours are a property of you.

How sensitive is that number?

A single figure invites more confidence than it deserves. Here is the same appliance under assumptions either side of the default, so you can see how much of the answer is the appliance and how much is the guess about how you use it.

Everything else held at the default. The spread here is the honest error bar on the headline figure.

The thing worth knowing

Screen size drives the number, not the technology: a 75-inch set draws roughly twice a 55-inch one. The store demo mode most sets ship in runs the backlight at maximum and can double the draw against the normal picture mode.

What it costs in your state

The appliance is the same everywhere; the rate is not. Running this LED television costs $90 a year in Hawaii and $22 in Nevada — a difference of 4×.

Questions

How much electricity does an LED television use?
About 171 kWh a year on the assumptions above — a 55-inch 4k set, five hours a day, out-of-the-box brightness. That works out to an average draw of 94 W over the hours it is in service, against a rated 90 W.
Is it expensive to run an LED television?
At the US average residential rate of 18.34¢ per kWh it costs about $31 a year, or $2.62 a month. The same appliance costs about $22 a year in Nevada and $90 in Hawaii, because the rate matters more than the appliance.
Why is your figure lower than other sites?
Because 90 W is what the appliance draws while it is actually drawing, not the average over the time it is switched on. Backlight draw is steady for a given brightness setting. Multiplying the rating by the hours gives 164 kWh a year, which is 1× the real figure.
What is the cheapest way to run an LED television?
Switch off the demo or vivid picture mode. It is a one-time change worth about 40% of the set’s consumption.
