Lg OLED65B4PU*
Rank #100 means 99 of the 172 television models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the Lg OLED65B4PU* cost to run per year?
Do the math and the Lg OLED65B4PU*'s $39/yr puts it at rank #100 of 172, right around the class average. Normalized for capacity, it beats 51% of television models we track, an average result for the class. At 114 W in on-mode, its power draw is a direct input into that running-cost figure.
Immediately around it on the leaderboard, the Lg 75QNED85AU* at $39/yr runs a little cheaper and the Samsung QN55S95FAF at $39/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 OLED65B4PU*'s $39/yr adds up to roughly $273 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED65B4PU* 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 $39/yr, here is what the Lg OLED65B4PU* 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 OLED65B4PU* costs about $390. That is roughly $40 more than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED65B4PU* compares
The television class we track runs from $3 to $117 a year. At $39/yr, it runs about $4 a year above the class median of $35, and it is about $36 a year more than the cheapest television to run at $3.
What drives its running cost
At 64.5 in, the Lg OLED65B4PU* 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. Its on-mode power draw of 114 W (the class spans 9.3 to 343.5 W) is the direct input into the running-cost figure, and the picture-brightness setting you choose is the single biggest lever you control over it day to day.
- 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.
- 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.
- 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 OLED65B4PU* cheap to run?
It is about average. At $39 a year it ranks #100 of 172 television models we track, close to the middle of its class on running cost.
How much does the Lg OLED65B4PU* cost per month?
Roughly $3.26/mo, spreading the $39/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 211 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $39 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg OLED65B4PU* for its size?
51st percentile once size is factored in, a fairly typical result for the class.
