TV power consumption and electricity cost
- Last Updated: February 25, 2023
Nowadays, TVs are rather efficient, so the electricity usage of a TV is quite low if we consider the amount of time they are powered on.
Still, it is good to know the electricity usage and the electricity cost to ensure there are no surprises once we receive the electricity bill.

How much power and electricity does a TV use
All the TVs should have a label describing, at the very least, their power consumption. Some TVs will also be labeled with information about standby power consumption.
If you are considering purchasing a new TV, you better have a look at the specifications. The power consumption of a TV can significantly increase our electricity bills, so better to know the electricity cost in advance.
For example, according to the specifications of our TV, it is estimated that it uses 532 Kilowatts per hour (kWh) per year.
Because we are paying our electricity provider 0,217 euros per every kWh we consume, our TV will cost us around 115 euros for electricity every year.
532 kWh x 0,217 euro per kWh = 115,44 euro per year
How to calculate power from voltage and current
If you only know the voltage and current of your TV, you can calculate the power consumption in Watts using the calculator below.
For more information about Power, Voltage, and Current, scroll down to the ‘Electricity Measurement Units’ section.
TV electricity cost calculator
The calculator below can calculate a TV’s energy consumption and cost over a year.
You just need to adjust the values in the PARAMETERS section to your requirements, and the calculator will automatically display the RESULTS section.
For example:
> If your TV has a power consumption of 532 kWh per year
> If you are paying 0,2 euros (or dollars or pounds) per every kWh you consume
You will be paying around 106 euros (or dollars, pounds, or…) per year in electricity costs.
How much does electricity cost
If you don’t know how much you are paying per kWh, you should be able to find the cost per kWh on your electricity contract or in one of the electricity bills.
Alternatively, if you don’t have access to your contract or your electricity bills, this website does show the electricity cost per country.
Home appliances and devices electricity calculators
A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:

TV electricity usage monitor
If you want to know the exact electricity usage of a TV, your best option is to use a plug-in power meter to measure the exact power consumption and electricity cost.
Clicking on the image below will redirect you to the Amazon page, where you can look at the specifications of the power meter we use for our measurements.
Our house appliances and devices like the washing machine, the dishwasher, the TV, or the printer are plugged into a wall socket.
So, with a power consumption meter, we can determine how much electricity our appliances or devices are using, and, more importantly, we can measure the electricity usage over time.
Have a look at this YouTube video for more information.
How to lower the electricity bill of a TV
If you are concerned that your TV may be using too much electricity, here are some tips that you can apply to reduce electricity usage:
1.- Enable the power-saving settings
Your TV is probably set up to stay in standby mode, waiting for your commands.
While on standby, your TV will use electricity, even if not in use. This is because your TV will use electricity while you are sleeping, away from home, or just cooking or showering.
If you would like to learn more about standby electricity usage, have a look at this video:
2.- The larger the TV is, the more electricity it will use
It may not always be the case, but the larger the TV is, the more electricity it will use. Be aware of this when you buy a new TV and look at the specifications, find the power usage, and compare it to other TV models.
TV electricity usage FAQ
How much electricity does a TV use in standby?
A TV in standby mode uses very little electricity, around 1 Watts per hour.
How much electricity does a smart TV use?
It depends on the TV model and usage.
According to our TV’s specifications, it uses 532 kWh per year.
The electricity usage, in Kilowatts hour, of a TV can be searched on the internet.
Once you know the power usage of your TV, you can use the calculator from the ‘Electricity cost calculator’ section to estimate the electricity cost.
How much electricity does a flat screen TV use?
It depends on the TV model and usage.
According to our TV’s specifications, it uses 532 kWh per year.
The electricity usage, in Kilowatts hour, of a TV can be searched on the internet.
Once you know the power usage of your TV, you can use the calculator from the ‘Electricity cost calculator’ section to estimate the electricity cost.
How much electricity does a TV use when off?
A TV does not use electricity when turned off.
Just ensure the TV is fully turned off and not on standby mode.
Electricity measurement units
Not everybody is familiar with terms like Watts, Kilowatts, or Kilowatt hours so if you would learn more about them, have a look at this YouTube video that we have prepared about this topic.
Electricity measurement units calculators
Or you can have a look at this electricity measurement units calculators to get a better understanding of:
> What is a Watt (W), and how to transform Watts into Kilowatts
> What is a Kilowatt (kW), and how to transform Kilowatts into Kilowatts hour
> What is a Kilowatt hour (kWh), and how to transform Kilowatts hours into other units
> What are Power (P), Voltage (V), and Current (I)
TVs and energy conservation
Energy conservation can be defined as the decision and the act of using less energy.
Energy conservation both benefit you and the environment
The act of saving and conserving electricity does benefit you because you will be paying less for your energy bills.
And it also benefits the environment because conserving electricity prevents unnecessary waste of natural resources.
At the individual level, it may not look worth trying to save a few watts here or there.
Still, every little one counts, and if hundreds or thousands of us save a little every time, it will make an important contribution towards conserving our natural resources.
Energy conservation calculator
If we could reduce our TV’s electricity usage, even a very small amount, it would greatly impact preserving our natural resources.
For example, if 9000 households save as little as 10 Watts per day (0,01 kWh) on the TV’s electricity usage, that would add to 32850 Kilowatt hours (kWh) saved per year.
9000 households x 0,01 kWh per day x 365 days per year
=
32,850 kWh saved per year
That is a considerable amount of electricity, but let’s add additional perspectives for clarity:
> Assuming an average cost of 0,18 euros (or dollars, pounds, or any other currency) per kWh, we would collectively save nearly 6000 euros annually.
> To produce 32,850 kWh of electricity, it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
Look at this page for more information about the resources needed to produce electricity.
In any case, small energy savings do count when looking into the bigger picture.
