Model
Lg OLED83C5P**
Rank #168 means 167 of the 172 television models we track cost less to run each year; the 3rd efficiency percentile means it uses less energy for its size than 3% of those models.
What does the Lg OLED83C5P** cost to run per year?
Out of the 172 television models we track, the Lg OLED83C5P** lands at rank #168 on cost, roughly $70 a year, one of the most expensive figures in the class. Its size-adjusted efficiency percentile of 3 means its running cost, whatever it is, owes almost nothing to efficiency and almost everything to capacity. This class has no published efficiency-factor figure beyond annual kWh itself, so at 82.5 in (the class spans 13.23 to 114.4), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Lg OLED83G5*** at $70/yr runs a little cheaper and the Samsung QN85QN90DAF at $72/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 OLED83C5P**'s $70/yr adds up to roughly $490 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED83C5P** 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 $70/yr, here is what the Lg OLED83C5P** 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 OLED83C5P** costs about $700. That is roughly $350 more than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED83C5P** compares
The television class we track runs from $3 to $117 a year. At $70/yr, it runs about $35 a year above the class median of $35, and it is about $67 a year more than the cheapest television to run at $3.
What drives its running cost
At 82.5 in, the Lg OLED83C5P** is a large television for its class, which spans 13.23 to 114.4 in with a median of 55 in, among television models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- Screen size. Screen size is the single strongest predictor of a TV's on-mode wattage, ahead of panel technology or brand.
- On-mode brightness. On-mode watts, the figure ENERGY STAR measures at the factory picture setting, can differ a lot from what a TV actually draws once you change the picture mode.
- Hours of use. Running cost compounds with hours of use, so this figure is really a per-hour rate multiplied by a standard viewing assumption, not a fixed annual bill.
Common questions
Is the Lg OLED83C5P** cheap to run?
Its $70/yr running cost, rank #168 of 172, is above what most television models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Lg OLED83C5P** cost per month?
About $5.83 a month, which is the $70 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 377 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $70 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg OLED83C5P** for its size?
3rd percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
