Model
Lg 65QNED85AU*
Rank #72 means 71 of the 172 television models we track cost less to run each year; the 72nd efficiency percentile means it uses less energy for its size than 72% of those models.
What does the Lg 65QNED85AU* cost to run per year?
The Lg 65QNED85AU* costs about $32 a year to run, a middle-of-the-pack figure at rank #72 of 172. Once capacity is factored in, its 72th efficiency percentile puts it ahead of most peers in its class. At 64.5 in, it is a mid-size 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 65QNED82AU* at $32/yr runs a little cheaper and the Lg 75QNED80AU* 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 65QNED85AU*'s $32/yr adds up to roughly $224 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 65QNED85AU* 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 65QNED85AU* 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 65QNED85AU* 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 65QNED85AU* 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 65QNED85AU* is a mid-size television for its class, which spans 13.23 to 114.4 in with a median of 55 in, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 65QNED85AU* cheap to run?
It is about average. At $32 a year it ranks #72 of 172 television models we track, close to the middle of its class on running cost.
How much does the Lg 65QNED85AU* cost per month?
Roughly $2.66/mo, spreading the $32/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 172 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $32 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg 65QNED85AU* for its size?
72nd percentile once size is factored in, a fairly typical result for the class.
