Model
Lg WM9500H*A
Rank #224 means 223 of the 388 washing machine models we track cost less to run each year; the 80th efficiency percentile means it uses less energy for its size than 80% of those models.
What does the Lg WM9500H*A cost to run per year?
Ranking #224 of 388, the Lg WM9500H*A runs at roughly $22 a year, neither the cheapest nor the priciest in its class. Adjusted for its imef, it is more efficient than 80% of washing machine models we track, a strong result once size is taken into account. At a IMEF of 3.1, 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 WM9000H*A at $22/yr runs a little cheaper and the Lg WT8200C* at $22/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 WM9500H*A's $22/yr adds up to roughly $220 in electricity alone, before purchase price or repairs.
By the numbers
The Lg WM9500H*A 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 $22/yr, here is what the Lg WM9500H*A 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 WM9500H*A costs about $220. That is roughly $20 more than the class median, which would run closer to $200 over the same ten years.
How the Lg WM9500H*A compares
The washing machine class we track runs from $7 to $58 a year. At $22/yr, it runs about $2 a year above the class median of $20, and it is about $15 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5.8 cu ft, the Lg WM9500H*A is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, among washing machine models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. Its IMEF of 3.1, above the class median of 2.76, reflects integrated modified energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- Spin and wash efficiency (IMEF). A higher Integrated Modified Energy Factor means the machine wrings more useful washing (and a drier spin) out of every kilowatt-hour and gallon it uses.
- Drum volume. Drum volume sets the ceiling on how much a single cycle can wash, and it is usually the first driver of a washer's per-cycle energy use.
- Water heating. Cycle temperature, more than drum size, is usually what separates a cheap wash cycle from an expensive one on models with an internal water heater.
Common questions
Is the Lg WM9500H*A cheap to run?
It is about average. At $22 a year it ranks #224 of 388 washing machine models we track, close to the middle of its class on running cost.
How much does the Lg WM9500H*A cost per month?
Roughly $1.86/mo, spreading the $22/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 120 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $22 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WM9500H*A for its size?
80th percentile once size is factored in, a fairly typical result for the class.
