Model
Beko BWM242300SWW
Rank #23 means 22 of the 388 washing machine models we track cost less to run each year; the 37th efficiency percentile means it uses less energy for its size than 37% of those models.
What does the Beko BWM242300SWW cost to run per year?
The Beko BWM242300SWW costs about $14 a year to run and sits near the top of the cheapest-to-run leaderboard, rank #23 of 388. Once capacity is factored in, its efficiency percentile of 37 is below the class median, worth weighing alongside the raw dollar figure. The IMEF figure of 2.3 on this model captures integrated modified energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Truarctic TAFW2422W at $13/yr runs a little cheaper and the Blomberg BLWM242300SWG at $14/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 Beko BWM242300SWW's $14/yr adds up to roughly $140 in electricity alone, before purchase price or repairs.

By the numbers
The Beko BWM242300SWW 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 $14/yr, here is what the Beko BWM242300SWW adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Beko BWM242300SWW costs about $140. That is roughly $60 less than the class median, which would run closer to $200 over the same ten years.
How the Beko BWM242300SWW compares
The washing machine class we track runs from $7 to $58 a year. At $14/yr, it runs about $6 a year cheaper than the class median of $20, and it is about $7 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.3 cu ft, the Beko BWM242300SWW 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. The IMEF of 2.3 on this model, below the class median of 2.76, measures integrated modified energy factor; it is the number to compare directly against another model's IMEF if capacity is similar.
- 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 Beko BWM242300SWW cheap to run?
Yes, relatively. At $14 a year it ranks #23 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Beko BWM242300SWW cost per month?
Roughly $1.13/mo, spreading the $14/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 73 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $14 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Beko BWM242300SWW for its size?
37th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
