LED-TV-power-consumption

If you are planning to buy a new LED TV or wondering how much electricity your existing LED TV is consuming then this article is for you. In this article, we will calculate the power consumption of an LED TV and also look at how much it costs to use one.

LED TVs have wattage between 20 watts to 200 watts. Generally, the bigger the size of the LED TV, the higher the wattage, and the higher the power consumption.

A 43-inch LED TV rated at around 100 watts, running for 8 hours a day will consume around 0.8 kWh in a day, 24 kWh in a month, and 292 kWh in a month.

This would roughly translate to a monthly electricity cost of $ 6.19 in the US, £ 8.64 in the UK, C$ 3.24 in Canada, A$ 7.68 in Australia, 232 in the Philippines, and Rs 240 in Mumbai, India.

Read the article to know how you can calculate the power consumption of your LED TV using a simple calculator.


How To Calculate The Power Consumption of LED TV:

The power consumption of an LED TV (for that matter any electrical appliance) depends upon two main things,

  1. First is the wattage of your LED TV,
  2. And second is the electricity tariff in your area.

Before we jump into calculating the power consumption of our LED TV let’s see what these terms are and how you can find out your LED TV’s wattage and the electricity tariff of your locality.

If you already know these terms and just want to use the calculator then please scroll down to use the calculator.


What is The Wattage of An LED TV:

Samsung 32-inch LED TV: 50 Watts

The wattage of LED TVs varies from 20 watts to 200 watts. Generally, the bigger the size of the TV, the higher the wattage.

For easy reference, In the table below, I have shown the wattage of different size LED TVs from Samsung, LG, and Sony.

LED TV SizeSamsung LED TVLG LED TVSony LED TV
24-inch LED TV25 watts30 watts‎20 Watts
32-inch LED TV50 watts‎45 watts‎51 Watts
43-inch LED TV110 watts ‎110 Watts‎96 Watts
55-inch LED TV155 watts 160 Watts‎142 Watts
65-inch LED TV200 watts‎195 Watts180 Watts

A few things to note from the above table,

  • Bigger the TV size, the higher the wattage. The wattage of a 24-inch LED TV is just 20 watts to 300 watts whereas, a 65-inch LED TV is rated at around 180 watts to 200 watts.
  • Irrespective of the brand, a specific size LED TV has similar wattage. For example, a 43-inch LED TV from Samsung has 80 watts, LG has 110 watts and Sony has 96 watts.

The above values are average values, you can expect a 5% to 10% variation on either side depending on the screen resolution (720p or 1080p), the wattage of the speaker, and other features.

If you want the exact wattage of your LED TV, then look for the technical specification label on its back or read the TV manual or just look for your LED TV on amazon and you will find its wattage in the description section.

LG 65-inch LED TV: 195 Watts

If you don’t have time to do this, then use values from the above table.

If this whole watt term is confusing you, then here is a quick explanation,

Watt is the unit of power. It means the rate at which electricity is consumed or produced by a device. For example, a 50-watt TV consumes power at a rate of 50 watts per hour, it does not mean that the TV consumed 50 units of electricity, it means it will consume power at a rate of 50 watts every hour.

So in short, the wattage of an LED TV lies between 20 watts to 200 watts and you can find it by looking at the label on it. With that out of the way, let’s look at what is electricity tariff.


What is your Electricity Tariff:

In simple words, electricity tariff is the amount your electricity provider charges you for one unit (kWh) of electricity. I live in Mumbai, India here the electricity tariff is Rs 12/kWh.

(What is a Kilowatt hour (kWh) Kilowatt hours or units of electricity is the energy consumption of a device. For example, a 50-watt table fan running for 50 hours will consume 50 watts x 50 hours = 2500-watt hours = 2.5-kilowatt hours of electricity = 2.5 units of electricity. (1 kWh of electricity = 1 unit of electricity))

To find your electricity tariff, just look into your previous month’s electricity bill and find out your monthly electricity consumption, then just divide your monthly electricity consumption by your total monthly electricity bill, the figure you get is approximately your electricity tariff.

I have put together the following table that shows the electricity tariff of a few countries.

Electricity Tariff Around The World:

LED TV Power Consumption:

With these two pieces of information in hand, you are ready to find the power consumption of your LED TV.

Let me show you an example,

LED-TV-electricity-consumption
Sony 43-inch LED TV: 96 Watts

I have selected a 43-inch LED TV from sony, it is rated at 96 Watts. (round it of to 100 watts for easy calculation)

Let’s assume we will use this 100 watts LED TV for 8 hours every day for the entire year.

With the knowledge of your LED TV wattage and your electricity tariff, just use this simple formula to calculate power consumption.

Power consumption of an appliance = Wattage of the appliance X operational hours

Cost to run an appliance = Power consumption of the appliance X electricity tariff

(Operational hours is basically the number of hours you are using your TV)

In our case, wattage is 100 watts and operational hours are 8 hours in a day, 240 hours in a month, and 2,920 hours in a year.

Hence by using the above formula.

  • Daily power consumption of a 100 watts LED TV (8 hours) = 100 watts X 8 hours = 0.8 kWh
  • Similarly, the Monthly power consumption of a 100 watts LED TV (8 hours/day @ 30 days) = 100 watts X 8 X 30 = 24 kWh
  • And the annual power consumption of 100 watts LED TV (8 hours/day @ 365 days) = 100 watts X 8 * 365 = 292 kWh

Similarly, In the table below I have calculated the daily, monthly, and annual power consumption of different sizes of Sony LED TVs.

LED TV SizeLED TV Daily Power Consumption (8 hours)LED TV Monthly Power Consumption (240 hours)LED TV Annual Power Consumption (2,920 hours)
24-inch LED TV (20 watts)0.16 kWh4.8 kWh58.4 kWh
32-inch LED TV (51 watts)0.41 kWh12.24 kWh148.92 kWh
43-inch LED TV (96 watts)0.77 kWh23.04 kWh280.32 kWh
55-inch LED TV (142 watts)1.14 kWh34.08 kWh414.64 kWh
65-inch LED TV (180 watts)1.44 kWh43.2 kWh525.6 kWh

IMP NOTE: One thing I would like to point out is, the above figures show the maximum power consumption of an LED TV. However, in reality, the power consumption of an LED TV can be 10% to 40% lower than the above values.

The reason is, the brightness of your TV is not at max settings all the time, you are not using internet on your TV all the time, and the speakers are not blasting at full power all the time. All these features consume extra power which in turn increases the running wattage of your TV, thus, increasing the overall power consumption of a TV.

If you are not using these features the running wattage of the TV will be less, thus, the overall power consumption will be less.


How much does it cost to run a LED TV?

Continuing with our above example of a 43-inch LED TV from Sony, let’s calculate how much it will cost us to run this TV.

Cost to run an appliance = Power consumption of the appliance X electricity tariff

let’s calculate how much it will cost to run this 100 watts LED TV for 8 hours every day for an entire month in Mumbai (India), the US, UK, and Canada.

  • In Mumbai, India, the avg. electricity tariff is around Rs 10 per kWh, hence it will cost around Rs 240 (24 kWh X Rs 10/kWh) to run this 100 watts LED TV for 8 hours every day for an entire month.
  • In the US, the avg. electricity tariff is around 16.20 cents per kWh, hence it will cost around $ 3.88 (24 kWh X 16.20 cents) to run this 100 watts LED TV for 8 hours every day for an entire month.
  • In the UK, the avg. electricity tariff is around 36 pence per kWh, hence it will cost around £ 8.64 (24 kWh X 36p/kWh) to run this 100 watts LED TV for 8 hours every day for an entire month.
  • In Canada, the avg. electricity tariff is around C$ 0.156 per kWh, hence it will cost around C$ 3.74 (24 kWh X C$ 0.156/kWh) to run this 100 watts LED TV for 8 hours every day for an entire month.

For your reference, I have calculated the power consumption and running costs of 24-inch, 32-inch, 43-inch, 55-inch, and 65-inch LED TVs.

LED TV Power Consumption Calculator:

As I explained before, the above figures show the maximum power consumption of your LED TV. However, in reality, the actual power consumption of your LED TV can be 10% to 40% lower than the above values depending on your usage.

If you are not happy with the approximate results and you want to know the exact power consumption of your LED TV, then I would suggest you buy a cheap Kill-A-Watt Meter from amazon.


Calculate the exact power consumption of any LED TV using Kill A Watt Meter:

Kill A Watt Meter is a simple device that gives real-time data on the power consumption of any device.

You can check it on amazon using this link – Kill A Watt Electricity Usage Monitor

To calculate the power consumption of your LED TV using a kill-a-watt meter, first, connect your LED TVs plug into the kill-a-watt meter and then plug the kill-a-watt meter in your wall socket and you are good to go.

Then start using your TV and you can see in real-time how many kWh (units) of electricity it is consuming.


Do LED TVs consume a lot of electricity?

No, LED TVs don’t consume a lot of electricity.

A 43-inch LED TV rated at around 100 watts, running for 8 hours a day will consume around just 24 kWh in a month, whereas, an average room heater rated at 1000 watts running for 8 hours a day will consume around 24 kWh of electricity in just 3 – 5 days.

The power consumption of LED TVs varies depending on the size and the brightness of the TV screen, the screen resolution (720p, 1080p, 4k, 8k), usage of the internet, and a few other features.
