Model
Lg OLED55C6PU*
Rank #94 means 93 of the 172 television models we track cost less to run each year; the 27th efficiency percentile means it uses less energy for its size than 27% of those models.
What does the Lg OLED55C6PU* cost to run per year?
The Lg OLED55C6PU* costs about $37 a year to run, a middle-of-the-pack figure at rank #94 of 172. Once capacity is factored in, its efficiency percentile of 27 is below the class median, worth weighing alongside the raw dollar figure. At 54.6 in, it is a mid-size 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 Samsung QN55S90HAE at $37/yr runs a little cheaper and the Samsung QN55S95HAF at $37/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 OLED55C6PU*'s $37/yr adds up to roughly $259 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED55C6PU* 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 $37/yr, here is what the Lg OLED55C6PU* 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 OLED55C6PU* costs about $370. That is roughly $20 more than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED55C6PU* compares
The television class we track runs from $3 to $117 a year. At $37/yr, it runs about $2 a year above the class median of $35, and it is about $34 a year more than the cheapest television to run at $3.
What drives its running cost
At 54.6 in, the Lg OLED55C6PU* 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. 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 OLED55C6PU* cheap to run?
It is about average. At $37 a year it ranks #94 of 172 television models we track, close to the middle of its class on running cost.
How much does the Lg OLED55C6PU* cost per month?
Roughly $3.11/mo, spreading the $37/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 201 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $37 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg OLED55C6PU* for its size?
27th percentile once size is factored in, a fairly typical result for the class.
