Model
Lg OLED65B5***
Rank #114 means 113 of the 172 television models we track cost less to run each year; the 33rd efficiency percentile means it uses less energy for its size than 33% of those models.
What does the Lg OLED65B5*** cost to run per year?
Ranking #114 of 172, the Lg OLED65B5*** sits in the pricier half of its class to run, at about $43 a year. Adjusted for size, it is only more efficient than 33% of television models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 64.5 in, it is a mid-size 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 Lg 86QNED80AU* at $43/yr runs a little cheaper and the Samsung QN65S95HAF at $43/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 OLED65B5***'s $43/yr adds up to roughly $301 in electricity alone, before purchase price or repairs.
Also sold as: Samsung QN65S95HAF.
By the numbers
The Lg OLED65B5*** 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 $43/yr, here is what the Lg OLED65B5*** 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 OLED65B5*** costs about $430. That is roughly $80 more than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED65B5*** compares
The television class we track runs from $3 to $117 a year. At $43/yr, it runs about $8 a year above the class median of $35, and it is about $40 a year more than the cheapest television to run at $3.
What drives its running cost
At 64.5 in, the Lg OLED65B5*** is a mid-size television for its class, which spans 13.23 to 114.4 in with a median of 55 in, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 OLED65B5*** cheap to run?
Not especially. At $43 a year it ranks #114 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 OLED65B5*** cost per month?
Roughly $3.62/mo, spreading the $43/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 234 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $43 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg OLED65B5*** for its size?
33rd 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.
