Model
Lg 65QNED82AU*
Rank #71 means 70 of the 172 television models we track cost less to run each year; the 73rd efficiency percentile means it uses less energy for its size than 73% of those models.
What does the Lg 65QNED82AU* cost to run per year?
The Lg 65QNED82AU* holds rank #71 of 172 on running cost, at about $32 a year, an unremarkable but typical figure for the class. Its size-adjusted efficiency percentile of 73 is comfortably above the class median. This class has no published efficiency-factor figure beyond annual kWh itself, so at 64.5 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 QN50QN90DAF at $31/yr runs a little cheaper and the Lg 65QNED85AU* at $32/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 65QNED82AU*'s $32/yr adds up to roughly $224 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 65QNED82AU* 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 $32/yr, here is what the Lg 65QNED82AU* 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 65QNED82AU* costs about $320. That is roughly $30 less than the class median, which would run closer to $350 over the same ten years.
How the Lg 65QNED82AU* compares
The television class we track runs from $3 to $117 a year. At $32/yr, it runs about $3 a year cheaper than the class median of $35, and it is about $29 a year more than the cheapest television to run at $3.
What drives its running cost
At 64.5 in, the Lg 65QNED82AU* is a mid-size television for its class, which spans 13.23 to 114.4 in with a median of 55 in, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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 65QNED82AU* cheap to run?
Roughly, yes. Its $32/yr figure is close to the class median, ranking #71 of 172, neither a bargain nor a splurge on running cost.
How much does the Lg 65QNED82AU* cost per month?
About $2.64 a month, which is the $32 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: 171 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $32 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg 65QNED82AU* for its size?
73rd percentile once size is factored in, a fairly typical result for the class.
