What does the Lg OLED65C4PU* cost to run per year?

The Lg OLED65C4PU* costs about $45 a year to run, more than most of the 172 television models we track; it ranks #119. Its size-adjusted efficiency percentile of 23 suggests its capacity is doing more work than its efficiency to keep the headline cost down. Its on-mode draw of 131.9 W is the number ENERGY STAR measures directly and the one this running-cost figure is built from.

Immediately around it on the leaderboard, the Samsung QN65S95FAF at $44/yr runs a little cheaper and the Samsung QN55S95DAF at $46/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 OLED65C4PU*'s $45/yr adds up to roughly $315 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $45/yr, here is what the Lg OLED65C4PU* 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 OLED65C4PU* costs about $450. That is roughly $100 more than the class median, which would run closer to $350 over the same ten years.

How the Lg OLED65C4PU* compares

The television class we track runs from $3 to $117 a year. At $45/yr, it runs about $10 a year above the class median of $35, and it is about $42 a year more than the cheapest television to run at $3.

What drives its running cost

At 64.5 in, the Lg OLED65C4PU* 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. 131.9 W is the on-mode draw behind this figure (the class spans 9.3 to 343.5 W); two otherwise similar TVs can differ here mostly on picture-mode defaults rather than panel technology.

  • 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.
  • Screen size. Screen size is the single strongest predictor of a TV's on-mode wattage, ahead of panel technology or brand.
  • 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 OLED65C4PU* cheap to run?

Its $45/yr running cost, rank #119 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 OLED65C4PU* cost per month?

About $3.77 a month, which is the $45 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: 244 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $45 a year. It covers electricity only, not the purchase price, water, or installation.

How efficient is the Lg OLED65C4PU* for its size?

23rd 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.
