Model
Lg 86QNED82AU*
Rank #128 means 127 of the 172 television models we track cost less to run each year; the 59th efficiency percentile means it uses less energy for its size than 59% of those models.
What does the Lg 86QNED82AU* cost to run per year?
At $49 a year to run, the Lg 86QNED82AU* runs more expensively than most models in its class, ranking #128 of 172 television models we track. Its 59th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. At 85.6 in, it is a large 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 OLED65C6PU* at $48/yr runs a little cheaper and the Lg OLED77B4PU* 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 86QNED82AU*'s $49/yr adds up to roughly $343 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 86QNED82AU* 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 86QNED82AU* 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 86QNED82AU* 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 86QNED82AU* 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 86QNED82AU* is a large television for its class, which spans 13.23 to 114.4 in with a median of 55 in, and larger television models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- 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 86QNED82AU* cheap to run?
Not especially. At $49 a year it ranks #128 of 172 television models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Lg 86QNED82AU* cost per month?
Roughly $4.05/mo, spreading the $49/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 262 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $49 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg 86QNED82AU* for its size?
59th 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.
