Model
Lg OLED55G6WU*
Rank #87 means 86 of the 172 television models we track cost less to run each year; the 40th efficiency percentile means it uses less energy for its size than 40% of those models.
What does the Lg OLED55G6WU* cost to run per year?
The Lg OLED55G6WU* costs about $35 a year to run, a fairly typical figure for the class; it ranks #87 of 172. Its size-adjusted efficiency percentile of 40 lands in the middle of the pack once capacity is accounted for. This class has no published efficiency-factor figure beyond annual kWh itself, so at 54.6 in (the class spans 13.23 to 114.4), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Lg 75QNED82AU* at $35/yr runs a little cheaper and the Sansui LE-65KA1 at $35/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 OLED55G6WU*'s $35/yr adds up to roughly $245 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED55G6WU* 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 $35/yr, here is what the Lg OLED55G6WU* 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 OLED55G6WU* costs about $350. That is roughly $0 less than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED55G6WU* compares
The television class we track runs from $3 to $117 a year. At $35/yr, it sits right on the class median of $35, and it is about $32 a year more than the cheapest television to run at $3.
What drives its running cost
At 54.6 in, the Lg OLED55G6WU* 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.
- Screen size. Screen size is the single strongest predictor of a TV's on-mode wattage, ahead of panel technology or brand.
- 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.
- 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 OLED55G6WU* cheap to run?
Roughly, yes. Its $35/yr figure is close to the class median, ranking #87 of 172, neither a bargain nor a splurge on running cost.
How much does the Lg OLED55G6WU* cost per month?
About $2.91 a month, which is the $35 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: 188 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $35 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg OLED55G6WU* for its size?
40th percentile once size is factored in, a fairly typical result for the class.
