Model
Lg 50QNED85AU*
Rank #29 means 28 of the 172 television models we track cost less to run each year; the 85th efficiency percentile means it uses less energy for its size than 85% of those models.
What does the Lg 50QNED85AU* cost to run per year?
At $22 a year to run, the Lg 50QNED85AU* is among the cheapest television models we track, ranking #29 of 172. Once capacity is factored in, it outperforms 85% of the television models we track on efficiency, not just on headline running cost. At 49.5 in, it is a small television for the class, which runs 13.23 to 114.4 in; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Lg 50QNED82AU* at $22/yr runs a little cheaper and the Samsung QN43QN90FAF at $22/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A television typically stays in service for somewhere around 7 years; over that span, the Lg 50QNED85AU*'s $22/yr adds up to roughly $154 in electricity alone, before purchase price or repairs.

By the numbers
The Lg 50QNED85AU* normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $22/yr, here is what the Lg 50QNED85AU* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Lg 50QNED85AU* costs about $220. That is roughly $130 less than the class median, which would run closer to $350 over the same ten years.
How the Lg 50QNED85AU* compares
The television class we track runs from $3 to $117 a year. At $22/yr, it runs about $13 a year cheaper than the class median of $35, and it is about $19 a year more than the cheapest television to run at $3.
What drives its running cost
At 49.5 in, the Lg 50QNED85AU* is a small television for its class, which spans 13.23 to 114.4 in with a median of 55 in, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- Screen size. A bigger panel needs more backlight or more emissive pixels to reach the same brightness, so energy use climbs with diagonal screen size across most panel technologies.
- On-mode brightness. The picture mode you leave a TV on, vivid or eco, moves its real-world wattage more than almost anything else you control directly.
- Hours of use. ENERGY STAR's on-mode wattage figure assumes a standard number of hours per day; a TV left on longer than that, or used as ambient background noise, accumulates more of that hourly cost.
Common questions
Is the Lg 50QNED85AU* cheap to run?
Yes, relatively. At $22 a year it ranks #29 of 172 television models we track, in the cheaper part of its class to run.
How much does the Lg 50QNED85AU* cost per month?
Roughly $1.84/mo, spreading the $22/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 119 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $22 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg 50QNED85AU* for its size?
85th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
