Model
Lg 55QNED85TU*
Rank #50 means 49 of the 172 television models we track cost less to run each year; the 76th efficiency percentile means it uses less energy for its size than 76% of those models.
What does the Lg 55QNED85TU* cost to run per year?
Ranking #50 of 172, the Lg 55QNED85TU* is in the cheaper half of its class to run, at about $26 a year. Normalized for capacity, it beats 76% of television models we track, a better-than-average efficiency result. At 76.9 W in on-mode, its power draw is a direct input into that running-cost figure.
Immediately around it on the leaderboard, the Samsung QN42S90FAE at $26/yr runs a little cheaper and the Samsung QN43QN90DAF at $27/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 55QNED85TU*'s $26/yr adds up to roughly $182 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 55QNED85TU* 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 $26/yr, here is what the Lg 55QNED85TU* 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 55QNED85TU* costs about $260. That is roughly $90 less than the class median, which would run closer to $350 over the same ten years.
How the Lg 55QNED85TU* compares
The television class we track runs from $3 to $117 a year. At $26/yr, it runs about $9 a year cheaper than the class median of $35, and it is about $23 a year more than the cheapest television to run at $3.
What drives its running cost
At 54.6 in, the Lg 55QNED85TU* 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. At 76.9 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 55QNED85TU* cheap to run?
Yes, relatively. At $26 a year it ranks #50 of 172 television models we track, in the cheaper part of its class to run.
How much does the Lg 55QNED85TU* cost per month?
Roughly $2.2/mo, spreading the $26/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 142 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $26 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg 55QNED85TU* for its size?
76th percentile once size is factored in, a fairly typical result for the class.
