Model
Lg OLED42C6PU*
Rank #27 means 26 of the 172 television models we track cost less to run each year; the 65th efficiency percentile means it uses less energy for its size than 65% of those models.
What does the Lg OLED42C6PU* cost to run per year?
Few television models we track cost less to run than the Lg OLED42C6PU*: about $22 a year, rank #27 of 172. Normalized for capacity, it beats 65% of television models we track, a better-than-average efficiency result. At 41.5 in, it is a small 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 Philips 50HFL4518U/27 at $21/yr runs a little cheaper and the Sansui LE-43V1 at $22/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 OLED42C6PU*'s $22/yr adds up to roughly $154 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED42C6PU* 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 $22/yr, here is what the Lg OLED42C6PU* 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 OLED42C6PU* costs about $220. That is roughly $130 less than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED42C6PU* compares
The television class we track runs from $3 to $117 a year. At $22/yr, it runs about $13 a year cheaper than the class median of $35, and it is about $19 a year more than the cheapest television to run at $3.
What drives its running cost
At 41.5 in, the Lg OLED42C6PU* is a small television for its class, which spans 13.23 to 114.4 in with a median of 55 in, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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 OLED42C6PU* cheap to run?
Yes, relatively. At $22 a year it ranks #27 of 172 television models we track, in the cheaper part of its class to run.
How much does the Lg OLED42C6PU* cost per month?
Roughly $1.81/mo, spreading the $22/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 117 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $22 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg OLED42C6PU* for its size?
65th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
