Model
Lg OLED77C6HU*
Rank #122 means 121 of the 172 television models we track cost less to run each year; the 52nd efficiency percentile means it uses less energy for its size than 52% of those models.
What does the Lg OLED77C6HU* cost to run per year?
The Lg OLED77C6HU* is a relatively costly runner for its class: about $46 a year, rank #122 of 172. Once capacity is factored in, its efficiency percentile of 52 is fairly typical for the class, neither a standout nor a laggard. At 76.7 in, it is a large 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 QN65S90FAF at $46/yr runs a little cheaper and the Lg OLED65G5*** at $47/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 OLED77C6HU*'s $46/yr adds up to roughly $322 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED77C6HU* 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 $46/yr, here is what the Lg OLED77C6HU* 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 OLED77C6HU* costs about $460. That is roughly $110 more than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED77C6HU* compares
The television class we track runs from $3 to $117 a year. At $46/yr, it runs about $11 a year above the class median of $35, and it is about $43 a year more than the cheapest television to run at $3.
What drives its running cost
At 76.7 in, the Lg OLED77C6HU* is a large television for its class, which spans 13.23 to 114.4 in with a median of 55 in, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- 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 OLED77C6HU* cheap to run?
Not especially. At $46 a year it ranks #122 of 172 television models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Lg OLED77C6HU* cost per month?
Roughly $3.87/mo, spreading the $46/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 250 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $46 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg OLED77C6HU* for its size?
52nd 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.
