Model
Lg WT7200C*
Rank #257 means 256 of the 388 washing machine models we track cost less to run each year; the 54th efficiency percentile means it uses less energy for its size than 54% of those models.
What does the Lg WT7200C* cost to run per year?
The Lg WT7200C* costs about $24 a year to run, more than most of the 388 washing machine models we track; it ranks #257. Capacity-normalized, it ranks ahead of 54% of washing machine models we track, right in the class's middle band. At a IMEF of 2.38, 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 WT1901C* at $24/yr runs a little cheaper and the Lg WT7400C* 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 WT7200C*'s $24/yr adds up to roughly $240 in electricity alone, before purchase price or repairs.
Also sold as: Lg WT1901C*.
By the numbers
The Lg WT7200C* 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 WT7200C* 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 WT7200C* 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 WT7200C* 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 cu ft, the Lg WT7200C* is a mid-size washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. Beyond size, its IMEF of 2.38, below 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 WT7200C* cheap to run?
Its $24/yr running cost, rank #257 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 WT7200C* 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 WT7200C* for its size?
54th 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.
