Model
Lg OLED48B4PU*
Rank #59 means 58 of the 172 television models we track cost less to run each year; the 57th efficiency percentile means it uses less energy for its size than 57% of those models.
What does the Lg OLED48B4PU* cost to run per year?
At roughly $28 a year to run, ranking #59 of 172, the Lg OLED48B4PU* costs less than the typical television model we track. Capacity-normalized, it ranks ahead of 57% of television models we track, right in the class's middle band. Its on-mode draw of 81.3 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 Philips 58HFL6214U/27 at $28/yr runs a little cheaper and the Samsung QN48S90DAE at $28/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 OLED48B4PU*'s $28/yr adds up to roughly $196 in electricity alone, before purchase price or repairs.
Also sold as: Samsung QN48S90DAE.
By the numbers
The Lg OLED48B4PU* 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 $28/yr, here is what the Lg OLED48B4PU* 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 OLED48B4PU* costs about $280. That is roughly $70 less than the class median, which would run closer to $350 over the same ten years.
How the Lg OLED48B4PU* compares
The television class we track runs from $3 to $117 a year. At $28/yr, it runs about $7 a year cheaper than the class median of $35, and it is about $25 a year more than the cheapest television to run at $3.
What drives its running cost
At 47.5 in, the Lg OLED48B4PU* is a small television for its class, which spans 13.23 to 114.4 in with a median of 55 in, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. 81.3 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 OLED48B4PU* cheap to run?
Yes. Its $28/yr running cost puts it at rank #59 of 172, below what most television models we track cost to run.
How much does the Lg OLED48B4PU* cost per month?
About $2.34 a month, which is the $28 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: 151 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $28 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg OLED48B4PU* for its size?
57th percentile once size is factored in, a fairly typical result for the class.
