Model
Lg OLED48C6PU*
Rank #33 means 32 of the 172 television models we track cost less to run each year; the 74th efficiency percentile means it uses less energy for its size than 74% of those models.
What does the Lg OLED48C6PU* cost to run per year?
At $23 a year to run, the Lg OLED48C6PU* is among the cheapest television models we track, ranking #33 of 172. Once capacity is factored in, its 74th efficiency percentile puts it ahead of most peers in its class. At 47.5 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 50HFL5214U/27 at $23/yr runs a little cheaper and the Sansui LE-40VA1 at $24/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 OLED48C6PU*'s $23/yr adds up to roughly $161 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED48C6PU* 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 $23/yr, here is what the Lg OLED48C6PU* 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 OLED48C6PU* costs about $230. That is roughly $120 less than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED48C6PU* compares
The television class we track runs from $3 to $117 a year. At $23/yr, it runs about $12 a year cheaper than the class median of $35, and it is about $20 a year more than the cheapest television to run at $3.
What drives its running cost
At 47.5 in, the Lg OLED48C6PU* 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.
- 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 OLED48C6PU* cheap to run?
Yes, relatively. At $23 a year it ranks #33 of 172 television models we track, in the cheaper part of its class to run.
How much does the Lg OLED48C6PU* cost per month?
Roughly $1.93/mo, spreading the $23/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 125 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $23 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg OLED48C6PU* for its size?
74th 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.
