Model
Lg 75QNED85AU*
Rank #99 means 98 of the 172 television models we track cost less to run each year; the 65th efficiency percentile means it uses less energy for its size than 65% of those models.
What does the Lg 75QNED85AU* cost to run per year?
At about $39 a year, the Lg 75QNED85AU* lands in the middle third of television models we track on running cost, rank #99 of 172. Its size-adjusted efficiency percentile of 65 is comfortably above the class median. This class has no published efficiency-factor figure beyond annual kWh itself, so at 74.5 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 Samsung QN65S85DAE at $38/yr runs a little cheaper and the Lg OLED65B4PU* at $39/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 75QNED85AU*'s $39/yr adds up to roughly $273 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 75QNED85AU* 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 $39/yr, here is what the Lg 75QNED85AU* 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 75QNED85AU* costs about $390. That is roughly $40 more than the class median, which would run closer to $350 over the same ten years.
How the Lg 75QNED85AU* compares
The television class we track runs from $3 to $117 a year. At $39/yr, it runs about $4 a year above the class median of $35, and it is about $36 a year more than the cheapest television to run at $3.
What drives its running cost
At 74.5 in, the Lg 75QNED85AU* 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 75QNED85AU* cheap to run?
Roughly, yes. Its $39/yr figure is close to the class median, ranking #99 of 172, neither a bargain nor a splurge on running cost.
How much does the Lg 75QNED85AU* cost per month?
About $3.25 a month, which is the $39 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: 210 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $39 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg 75QNED85AU* for its size?
65th percentile once size is factored in, a fairly typical result for the class.
