Model
Lg 75QNED85TU*
Rank #126 means 125 of the 172 television models we track cost less to run each year; the 39th efficiency percentile means it uses less energy for its size than 39% of those models.
What does the Lg 75QNED85TU* cost to run per year?
At $48 a year to run, the Lg 75QNED85TU* runs more expensively than most models in its class, ranking #126 of 172 television models we track. Its 39th size-adjusted efficiency percentile is a step behind the class median, though not among the weakest results. At 140.7 W in on-mode, its power draw is a direct input into that running-cost figure.
Immediately around it on the leaderboard, the Lg 75QNED90TU* at $48/yr runs a little cheaper and the Lg OLED65C6PU* at $48/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 75QNED85TU*'s $48/yr adds up to roughly $336 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 75QNED85TU* 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 $48/yr, here is what the Lg 75QNED85TU* 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 75QNED85TU* costs about $480. That is roughly $130 more than the class median, which would run closer to $350 over the same ten years.
How the Lg 75QNED85TU* compares
The television class we track runs from $3 to $117 a year. At $48/yr, it runs about $13 a year above the class median of $35, and it is about $45 a year more than the cheapest television to run at $3.
What drives its running cost
At 74.5 in, the Lg 75QNED85TU* is a large television for its class, which spans 13.23 to 114.4 in with a median of 55 in, among television models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. 140.7 W is the on-mode draw behind this figure (the class spans 9.3 to 343.5 W); two otherwise similar TVs can differ here mostly on picture-mode defaults rather than panel technology.
- 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 75QNED85TU* cheap to run?
Not especially. At $48 a year it ranks #126 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 75QNED85TU* cost per month?
Roughly $4.02/mo, spreading the $48/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 260 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $48 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg 75QNED85TU* for its size?
39th 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.
