Model
Lg 50QNED85TU*
Rank #46 means 45 of the 172 television models we track cost less to run each year; the 68th efficiency percentile means it uses less energy for its size than 68% of those models.
What does the Lg 50QNED85TU* cost to run per year?
At about $25 a year, the Lg 50QNED85TU* undercuts most television models we track on running cost, rank #46 of 172. Capacity-normalized, it ranks ahead of 68% of television models we track, a reasonably strong result for the class. Its on-mode draw of 73.2 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 Sansui LE-55V4 at $25/yr runs a little cheaper and the Lg OLED42C4PU* at $25/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 50QNED85TU*'s $25/yr adds up to roughly $175 in electricity alone, before purchase price or repairs.
By the numbers
The Lg 50QNED85TU* 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 $25/yr, here is what the Lg 50QNED85TU* 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 50QNED85TU* costs about $250. That is roughly $100 less than the class median, which would run closer to $350 over the same ten years.
How the Lg 50QNED85TU* compares
The television class we track runs from $3 to $117 a year. At $25/yr, it runs about $10 a year cheaper than the class median of $35, and it is about $22 a year more than the cheapest television to run at $3.
What drives its running cost
At 49.5 in, the Lg 50QNED85TU* is a small television for its class, which spans 13.23 to 114.4 in with a median of 55 in, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its on-mode power draw of 73.2 W (the class spans 9.3 to 343.5 W) is the direct input into the running-cost figure, and the picture-brightness setting you choose is the single biggest lever you control over it day to day.
- 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 50QNED85TU* cheap to run?
Yes. Its $25/yr running cost puts it at rank #46 of 172, below what most television models we track cost to run.
How much does the Lg 50QNED85TU* cost per month?
About $2.1 a month, which is the $25 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: 136 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $25 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg 50QNED85TU* for its size?
68th percentile once size is factored in, a fairly typical result for the class.
