Model
Lg OLED65C5***
Rank #136 means 135 of the 172 television models we track cost less to run each year; the 10th efficiency percentile means it uses less energy for its size than 10% of those models.
What does the Lg OLED65C5*** cost to run per year?
At about $51 a year, the Lg OLED65C5*** costs more to run than most television models we track, rank #136 of 172. Size-adjusted, this model ranks near the bottom of its class on efficiency, ahead of just 10% of television models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 64.5 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 Sansui LE-75VA1 at $51/yr runs a little cheaper and the Samsung QN65QN95DAF at $51/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 OLED65C5***'s $51/yr adds up to roughly $357 in electricity alone, before purchase price or repairs.
Also sold as: Samsung QN65QN95DAF.
By the numbers
The Lg OLED65C5*** 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 $51/yr, here is what the Lg OLED65C5*** 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 OLED65C5*** costs about $510. That is roughly $160 more than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED65C5*** compares
The television class we track runs from $3 to $117 a year. At $51/yr, it runs about $16 a year above the class median of $35, and it is about $48 a year more than the cheapest television to run at $3.
What drives its running cost
At 64.5 in, the Lg OLED65C5*** 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.
- 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 OLED65C5*** cheap to run?
Its $51/yr running cost, rank #136 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 OLED65C5*** cost per month?
About $4.25 a month, which is the $51 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: 275 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $51 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg OLED65C5*** for its size?
10th 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.
