What does the Lg OLED48C5*** cost to run per year?

Ranking #68 of 172, the Lg OLED48C5*** is in the cheaper half of its class to run, at about $30 a year. Normalized for capacity, it beats 43% of television models we track, an average result for the class. At 87 W in on-mode, its power draw is a direct input into that running-cost figure.

Immediately around it on the leaderboard, the Xitrix XPN-DSA6560 at $30/yr runs a little cheaper and the Samsung QN55S85DAE at $31/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 OLED48C5***'s $30/yr adds up to roughly $210 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 $30/yr, here is what the Lg OLED48C5*** adds up to before purchase price, water, or repairs enter the math.

1 year$30
5 years$150
10 years$300

Left running for a decade at today's US average rate, the Lg OLED48C5*** costs about $300. That is roughly $50 less than the class median, which would run closer to $350 over the same ten years.

What drives its running cost

At 47.5 in, the Lg OLED48C5*** 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. Its on-mode power draw of 87 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 OLED48C5*** cheap to run?

Yes, relatively. At $30 a year it ranks #68 of 172 television models we track, in the cheaper part of its class to run.

How much does the Lg OLED48C5*** cost per month?

Roughly $2.51/mo, spreading the $30/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 162 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $30 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.

How efficient is the Lg OLED48C5*** for its size?

43rd percentile once size is factored in, a fairly typical result for the class.
