Watts to kWh
kWh = (W ÷ 1,000) × hours × load factor. Multiply kWh by your electricity price to estimate energy cost.
📺 Worked example
How much electricity does a television use?
Check whether the label gives separate SDR and HDR figures. Replace example inputs with your own usage pattern.
0.40 kWhper day of use
2.40 €per month at 0.20 €/kWh
Worked example
100 W × 4 h/day × 100 % load factor × 30 days.
12.00 kWh/month · 28.80 €/year
This is an energy-only estimate. Your bill can also include standing charges, taxes and other household consumption.
Typical reference range
Use the label, manual or manufacturer data for your exact model whenever possible.
| Type or situation | Indicative reference |
|---|---|
| Small efficient TV | 30–70 W |
| Typical 50–55 inch TV | 70–140 W |
| Large / very bright TV | 120–250+ W |
What changes the result?
Rated watts are only one part of the calculation.
Measure when possible
Thermostats, compressors, inverter control and programmes can make real consumption lower or higher than a simple maximum-power estimate.
Practical checks
- Brightness and HDR use can change power draw.
- Disable unnecessary high-brightness shop modes.
- Standby is usually small but can be measured over several days.

Check the real energy use of your television
Electricity use varies with screen brightness, size, display mode and HDR content. A label expressed as kWh per 1,000 hours can be converted to a personal period by multiplying by actual hours and dividing by 1,000. External set-top boxes and consoles are separate loads.
Checklist to reproduce the comparison
- Check whether the label gives separate SDR and HDR figures.
- Use your actual viewing hours rather than a generic household average.
- Add connected boxes, consoles or sound systems separately.
The figures elsewhere on this page are illustrative assumptions, not a measured average for every model. Use the label, your actual cycle count and safely collected kWh readings.
Estimate TV electricity cost from the energy label
Read your model's kWh per 1,000 hours in SDR and HDR from its EU energy label. They describe test-condition energy use per 1,000 hours, not what your household spends in a calendar year. Enter your hours and electricity rate to estimate your own use.
How the estimate works
Screen electricity: SDR and HDR label values × yearly hours in each mode ÷ 1,000. Standby electricity: standby watts × the remaining hours (24 minus viewing hours per day) × 365 ÷ 1,000, assuming the TV stays plugged in when not watched. Multiply the sum of kWh by your electricity price.
With the illustrative figures above, the estimate is 102.38 kWh and €20.48 per year at €0.20/kWh. Actual consumption may change with brightness, picture mode and accessories. Fixed charges and taxes are not included.
Find the model's label and data sheet using the European Commission's EPREL. The energy-label measurement is described in Commission Delegated Regulation (EU) 2019/2013. The standby figure comes from the technical specifications, not necessarily the front of the label.
