Television Electricity Cost Per Watched Hour Used: Include Picture Mode and Streaming Gear
Quick answer: Estimate a television’s cost per watched hour from measured on-mode and standby energy, picture settings, streaming equipment, electricity rates, and useful viewing hours instead of screen size alone.
Inputs that change the result
Measure TV wall watts in default, bright, HDR, gaming, sleep, and network-standby modes. Record streaming box, soundbar, console, hours watched, idle time, rate and delivery charges, and whether the screen is shared by several viewers.
Formula and worked example
effective watched-hour cost = (TV on energy + attributable standby + streaming and audio energy + delivery charges + equipment allocation) ÷ useful watched hours. State whether the denominator is viewing time or total powered-on time. A TV averages 90 W for 4 watched hours and 1 W for 20 standby hours, using 0.38 kWh. At 0.20/kWh, direct energy is 0.08 per day. Add a 12 W streaming box and 25 W soundbar only for their actual powered hours; a large screen is not automatically a higher cost per hour.
Compare real use cases
Compare default picture mode, a bright HDR film, and gaming with a console and soundbar. ENERGY STAR television criteria distinguish on-mode and standby behavior; they do not include every external device or your local rate.

Limits and common mistakes
Brightness, HDR, refresh rate, network activity, connected devices, automatic power-down, and content can change draw. Do not convert a published efficiency percentage into your bill, and do not count subscription fees as electricity cost in the same denominator.
Frequently asked questions
Should streaming devices be included?
Include them when the question is the cost of the complete viewing setup. Report the TV alone as a separate line so viewers can see whether the main screen, sound, or streaming hardware drives the result.
