Model
Lg 75QNED80AU*
Rank #73 means 72 of the 172 television models we track cost less to run each year; the 86th efficiency percentile means it uses less energy for its size than 86% of those models.
What does the Lg 75QNED80AU* cost to run per year?
Do the math and the Lg 75QNED80AU*'s $32/yr puts it at rank #73 of 172, right around the class average. Adjusted for its size, it is more efficient than 86% of television models we track, a strong result once size is taken into account. At 74.5 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 65QNED85AU* at $32/yr runs a little cheaper and the Lg 65QNED80AU* at $33/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 75QNED80AU*'s $32/yr adds up to roughly $224 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 75QNED80AU* 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 75QNED80AU* 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 75QNED80AU* 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 75QNED80AU* 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 74.5 in, the Lg 75QNED80AU* is a large television for its class, which spans 13.23 to 114.4 in with a median of 55 in, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- 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 75QNED80AU* cheap to run?
It is about average. At $32 a year it ranks #73 of 172 television models we track, close to the middle of its class on running cost.
How much does the Lg 75QNED80AU* cost per month?
Roughly $2.71/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 175 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 75QNED80AU* for its size?
86th percentile once size is factored in, a fairly typical result for the class.
