Estimate TV electricity cost
How this calculator works
Screen size, brightness, picture mode, HDR content, and panel technology affect television power. This calculator combines active viewing with standby time for a fuller estimate.
Streaming boxes, soundbars, game consoles, receivers, and network equipment are separate loads and should be added with the appliance or standby-power calculators.
A 100-watt TV watched five hours per day with 0.5-watt standby uses about 15.3 kWh per month and costs about $2.76 at $0.18/kWh.
How to get a more accurate estimate
- Use measured on-mode watts for your normal picture setting.
- Add external entertainment devices separately.
- Reduce excessive brightness or disable unnecessary quick-start features when practical.
Frequently asked questions
Does a larger TV always use more electricity?
Larger screens often use more, but panel technology, efficiency, brightness, and settings also matter.
Is standby power important?
A fraction of a watt is small, but multiple devices operating all year can add up.
Does 4K content use more power?
Power can change with brightness, HDR, processing, and content, but the difference varies by model.
Results use the values you enter and the formula shown above. Real bills can include taxes, minimum charges, tiers, time-of-use pricing, cycling losses, and other adjustments. Use a recent bill or a plug-in energy meter when accuracy matters.
