Indicative diagram of this calculator inputs — Cost depends on real power draw, usage time and the price per kWh.

How we calculate consumption

We convert watts to kilowatts and multiply by hours, days and load factor, then apply the electricity price.

W ÷ 1000 × hours × load × days × €/kWh

Rated power and average consumption differ

The label is a reference, but consumption changes with picture and settings. A plug-in meter can replace the estimate with a measured value.

Compare habits using the same assumptions

When comparing two TVs, use the same hours, days and tariff so most of the difference comes from power use.

Why TV power changes during normal viewing

A television does not necessarily draw the same power all the time. Screen brightness, HDR, panel technology, picture mode and the content being displayed can all change real consumption compared with a single label value.

Use measured average power when possible

If you have a plug-in meter, measure the TV during typical viewing rather than using a maximum or peak figure. A sports broadcast, a dark film and an HDR game can create different average demand on some displays.

Standby is separate from viewing

The calculator estimates active use from the hours you enter. If standby consumption matters, measure or estimate that separately rather than increasing active viewing hours.

For a worked reference, see how much electricity a television uses. For better measurement practice, read how to measure appliance consumption.

If you are in Spain, replace the default tariff with the current electricity price.
