Model
Lg 55QNED85AU*
Rank #56 means 55 of the 172 television models we track cost less to run each year; the 71st efficiency percentile means it uses less energy for its size than 71% of those models.
What does the Lg 55QNED85AU* cost to run per year?
Among the 172 television models we track, the Lg 55QNED85AU* sits in the below-average-cost group, rank #56, at roughly $27 a year. Size-adjusted, this model beats 71% of television models we track on efficiency, better than most of its class. This class has no published efficiency-factor figure beyond annual kWh itself, so at 54.6 in (the class spans 13.23 to 114.4), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Sansui LE-55TA1 at $27/yr runs a little cheaper and the Philips 55HFL4518U/27 at $28/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 55QNED85AU*'s $27/yr adds up to roughly $189 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 55QNED85AU* 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 $27/yr, here is what the Lg 55QNED85AU* 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 55QNED85AU* costs about $270. That is roughly $80 less than the class median, which would run closer to $350 over the same ten years.
How the Lg 55QNED85AU* compares
The television class we track runs from $3 to $117 a year. At $27/yr, it runs about $8 a year cheaper than the class median of $35, and it is about $24 a year more than the cheapest television to run at $3.
What drives its running cost
At 54.6 in, the Lg 55QNED85AU* is a mid-size television for its class, which spans 13.23 to 114.4 in with a median of 55 in, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- Screen size. Screen size is the single strongest predictor of a TV's on-mode wattage, ahead of panel technology or brand.
- On-mode brightness. On-mode watts, the figure ENERGY STAR measures at the factory picture setting, can differ a lot from what a TV actually draws once you change the picture mode.
- Hours of use. Running cost compounds with hours of use, so this figure is really a per-hour rate multiplied by a standard viewing assumption, not a fixed annual bill.
Common questions
Is the Lg 55QNED85AU* cheap to run?
Yes. Its $27/yr running cost puts it at rank #56 of 172, below what most television models we track cost to run.
How much does the Lg 55QNED85AU* cost per month?
About $2.27 a month, which is the $27 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 147 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $27 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg 55QNED85AU* for its size?
71st percentile once size is factored in, a fairly typical result for the class.
