Model
Lg OLED55B5***
Rank #96 means 95 of the 172 television models we track cost less to run each year; the 24th efficiency percentile means it uses less energy for its size than 24% of those models.
What does the Lg OLED55B5*** cost to run per year?
The Lg OLED55B5*** holds rank #96 of 172 on running cost, at about $38 a year, an unremarkable but typical figure for the class. Size-adjusted, this model trails most of its class on efficiency, ahead of just 24% of television models we track. Its on-mode draw of 100.2 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 QN55S95HAF at $37/yr runs a little cheaper and the Lg 65QNED85TU* at $38/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 OLED55B5***'s $38/yr adds up to roughly $266 in electricity alone, before purchase price or repairs.
By the numbers
The Lg OLED55B5*** 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 $38/yr, here is what the Lg OLED55B5*** 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 OLED55B5*** costs about $380. That is roughly $30 more than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED55B5*** compares
The television class we track runs from $3 to $117 a year. At $38/yr, it runs about $3 a year above the class median of $35, and it is about $35 a year more than the cheapest television to run at $3.
What drives its running cost
At 54.6 in, the Lg OLED55B5*** 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. 100.2 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 OLED55B5*** cheap to run?
Roughly, yes. Its $38/yr figure is close to the class median, ranking #96 of 172, neither a bargain nor a splurge on running cost.
How much does the Lg OLED55B5*** cost per month?
About $3.17 a month, which is the $38 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: 205 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $38 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg OLED55B5*** for its size?
24th percentile once size is factored in, a fairly typical result for the class.
