Model
Lg 86QNED85AU*
Rank #130 means 129 of the 172 television models we track cost less to run each year; the 58th efficiency percentile means it uses less energy for its size than 58% of those models.
What does the Lg 86QNED85AU* cost to run per year?
At about $49 a year, the Lg 86QNED85AU* costs more to run than most television models we track, rank #130 of 172. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 58% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 85.6 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 Lg OLED77B4PU* at $49/yr runs a little cheaper and the Samsung QN65QN90DAF at $49/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 86QNED85AU*'s $49/yr adds up to roughly $343 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 86QNED85AU* 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 $49/yr, here is what the Lg 86QNED85AU* 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 86QNED85AU* costs about $490. That is roughly $140 more than the class median, which would run closer to $350 over the same ten years.
How the Lg 86QNED85AU* compares
The television class we track runs from $3 to $117 a year. At $49/yr, it runs about $14 a year above the class median of $35, and it is about $46 a year more than the cheapest television to run at $3.
What drives its running cost
At 85.6 in, the Lg 86QNED85AU* is a large television for its class, which spans 13.23 to 114.4 in with a median of 55 in, among television models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- 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 86QNED85AU* cheap to run?
Its $49/yr running cost, rank #130 of 172, is above what most television models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Lg 86QNED85AU* cost per month?
About $4.08 a month, which is the $49 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: 264 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $49 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg 86QNED85AU* for its size?
58th 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.
