Model
Lg 65QNED90TU*
Rank #104 means 103 of the 172 television models we track cost less to run each year; the 46th efficiency percentile means it uses less energy for its size than 46% of those models.
What does the Lg 65QNED90TU* cost to run per year?
At about $40 a year, the Lg 65QNED90TU* costs more to run than most television models we track, rank #104 of 172. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 46% of the models we track. Its on-mode draw of 117 W is the number ENERGY STAR measures directly and the one this running-cost figure is built from.
Immediately around it on the leaderboard, the Samsung QN65S85FAF at $40/yr runs a little cheaper and the Rca 65D1 at $40/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 65QNED90TU*'s $40/yr adds up to roughly $280 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 65QNED90TU* 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 $40/yr, here is what the Lg 65QNED90TU* 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 65QNED90TU* costs about $400. That is roughly $50 more than the class median, which would run closer to $350 over the same ten years.
How the Lg 65QNED90TU* compares
The television class we track runs from $3 to $117 a year. At $40/yr, it runs about $5 a year above the class median of $35, and it is about $37 a year more than the cheapest television to run at $3.
What drives its running cost
At 64.5 in, the Lg 65QNED90TU* 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 117 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. On-mode watts, the figure ENERGY STAR measures at the factory picture setting, can differ a lot from what a TV actually draws once you change the picture mode.
- Screen size. Screen size is the single strongest predictor of a TV's on-mode wattage, ahead of panel technology or brand.
- Hours of use. Running cost compounds with hours of use, so this figure is really a per-hour rate multiplied by a standard viewing assumption, not a fixed annual bill.
Common questions
Is the Lg 65QNED90TU* cheap to run?
Its $40/yr running cost, rank #104 of 172, is above what most television models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Lg 65QNED90TU* cost per month?
About $3.34 a month, which is the $40 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 216 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $40 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg 65QNED90TU* for its size?
46th 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.
