Model
Lg WT7480C*
Rank #259 means 258 of the 388 washing machine models we track cost less to run each year; the 62nd efficiency percentile means it uses less energy for its size than 62% of those models.
What does the Lg WT7480C* cost to run per year?
Among the 388 washing machine models we track, the Lg WT7480C*'s $24/yr running cost ranks it #259, in the above-average-cost group. Capacity-normalized, it ranks ahead of 62% of washing machine models we track, a reasonably strong result for the class. At a IMEF of 2.76, its integrated modified energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Lg WT7400C* at $24/yr runs a little cheaper and the Lg WT7500C* at $24/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A washing machine typically stays in service for somewhere around 10 years; over that span, the Lg WT7480C*'s $24/yr adds up to roughly $240 in electricity alone, before purchase price or repairs.

By the numbers
The Lg WT7480C* 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 $24/yr, here is what the Lg WT7480C* 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 WT7480C* costs about $240. That is roughly $40 more than the class median, which would run closer to $200 over the same ten years.
How the Lg WT7480C* compares
The washing machine class we track runs from $7 to $58 a year. At $24/yr, it runs about $4 a year above the class median of $20, and it is about $17 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5.5 cu ft, the Lg WT7480C* is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. Beyond size, its IMEF of 2.76, above the class median of 2.76, is the class's own efficiency yardstick, integrated modified energy factor, and it is what separates two similarly sized models with different running costs.
- Spin and wash efficiency (IMEF). IMEF is this class's core efficiency yardstick; two washers with the same drum size can carry meaningfully different IMEF figures and running costs.
- Drum volume. A larger-capacity washer can wash more per load, which can lower cost per pound of laundry, but it also draws more water and energy per cycle if you are not filling it.
- Water heating. Most washers rely on your home's hot water supply, but internal-heater sanitize or hot-wash cycles use meaningfully more electricity than a cold or warm wash.
Common questions
Is the Lg WT7480C* cheap to run?
Its $24/yr running cost, rank #259 of 388, is above what most washing machine models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Lg WT7480C* cost per month?
About $2.01 a month, which is the $24 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: 130 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $24 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg WT7480C* for its size?
62nd percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
