Model
Lg 86QNED90TU*
Rank #156 means 155 of the 172 television models we track cost less to run each year; the 16th efficiency percentile means it uses less energy for its size than 16% of those models.
What does the Lg 86QNED90TU* cost to run per year?
Do the math and the Lg 86QNED90TU*'s $63/yr puts it at rank #156 of 172, one of the costlier television models we track to keep running. Normalized for capacity, it beats only 16% of television models we track, one of the weaker efficiency results we track for the class. At 184.6 W in on-mode, its power draw is a direct input into that running-cost figure.
Immediately around it on the leaderboard, the Lg OLED83B5PU* at $61/yr runs a little cheaper and the Lg OLED77B5*** at $64/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 86QNED90TU*'s $63/yr adds up to roughly $441 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 86QNED90TU* 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 $63/yr, here is what the Lg 86QNED90TU* 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 86QNED90TU* costs about $630. That is roughly $280 more than the class median, which would run closer to $350 over the same ten years.
How the Lg 86QNED90TU* compares
The television class we track runs from $3 to $117 a year. At $63/yr, it runs about $28 a year above the class median of $35, and it is about $60 a year more than the cheapest television to run at $3.
What drives its running cost
At 85.6 in, the Lg 86QNED90TU* 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. At 184.6 W on-mode (the class spans 9.3 to 343.5 W), its power draw is what ENERGY STAR actually measured to produce this running-cost figure; brightness settings move that wattage more than screen size alone.
- 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.
- 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.
- 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 86QNED90TU* cheap to run?
Not especially. At $63 a year it ranks #156 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 86QNED90TU* cost per month?
Roughly $5.26/mo, spreading the $63/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 340 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $63 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg 86QNED90TU* for its size?
16th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
