Model
Lg OLED55C4PU*
Rank #90 means 89 of the 172 television models we track cost less to run each year; the 38th efficiency percentile means it uses less energy for its size than 38% of those models.
What does the Lg OLED55C4PU* cost to run per year?
Do the math and the Lg OLED55C4PU*'s $35/yr puts it at rank #90 of 172, right around the class average. Normalized for capacity, it beats only 38% of television models we track, a below-average efficiency result. At 103.1 W in on-mode, its power draw is a direct input into that running-cost figure.
Immediately around it on the leaderboard, the Xitrix XPN-DSA6550 at $35/yr runs a little cheaper and the Samsung QN55QN90FAF at $36/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 OLED55C4PU*'s $35/yr adds up to roughly $245 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED55C4PU* 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 OLED55C4PU* 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 OLED55C4PU* 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 OLED55C4PU* 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 OLED55C4PU* 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. Its on-mode power draw of 103.1 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. The picture mode you leave a TV on, vivid or eco, moves its real-world wattage more than almost anything else you control directly.
- 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.
- 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 OLED55C4PU* cheap to run?
It is about average. At $35 a year it ranks #90 of 172 television models we track, close to the middle of its class on running cost.
How much does the Lg OLED55C4PU* cost per month?
Roughly $2.95/mo, spreading the $35/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 191 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $35 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg OLED55C4PU* for its size?
38th percentile once size is factored in, a fairly typical result for the class.
