Model
Summit LBW241
Rank #99 means 98 of the 388 washing machine models we track cost less to run each year; the 1st efficiency percentile means it uses less energy for its size than 1% of those models.
What does the Summit LBW241 cost to run per year?
The Summit LBW241 is a relatively cheap runner for its class: about $19 a year, rank #99 of 388. Its 1th size-adjusted efficiency percentile sits at the floor of the class, a figure worth weighing carefully against the raw cost above. At 1.9 cu ft, it is a small washing machine for the class, which runs 1.9 to 6 cu ft; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Samsung WF50R85**A* at $19/yr runs a little cheaper and the Summit LBW243 at $19/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 Summit LBW241's $19/yr adds up to roughly $190 in electricity alone, before purchase price or repairs.
Also sold as: Aviva ALWF190WH.
By the numbers
The Summit LBW241 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 $19/yr, here is what the Summit LBW241 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Summit LBW241 costs about $190. That is roughly $10 less than the class median, which would run closer to $200 over the same ten years.
How the Summit LBW241 compares
The washing machine class we track runs from $7 to $58 a year. At $19/yr, it runs about $1 a year cheaper than the class median of $20, and it is about $12 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 1.9 cu ft, the Summit LBW241 is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, 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.
- 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.
- 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.
- 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 Summit LBW241 cheap to run?
Yes, relatively. At $19 a year it ranks #99 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Summit LBW241 cost per month?
Roughly $1.55/mo, spreading the $19/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 100 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $19 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Summit LBW241 for its size?
1st percentile once size is factored in, a fairly typical result for the class.
