Model
Samsung WW25FG5B****
Rank #66 means 65 of the 388 washing machine models we track cost less to run each year; the 29th efficiency percentile means it uses less energy for its size than 29% of those models.
What does the Samsung WW25FG5B**** cost to run per year?
Few washing machine models we track cost less to run than the Samsung WW25FG5B****: about $17 a year, rank #66 of 388. Normalized for capacity, it beats only 29% of washing machine models we track, a below-average efficiency result. The IMEF figure of 2.25 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 Samsung WW25B69**A* at $17/yr runs a little cheaper and the Samsung WW25FG6B**** at $17/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 Samsung WW25FG5B****'s $17/yr adds up to roughly $170 in electricity alone, before purchase price or repairs.
Also sold as: Samsung WW25B68**A*.
By the numbers
The Samsung WW25FG5B**** 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 $17/yr, here is what the Samsung WW25FG5B**** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Samsung WW25FG5B**** costs about $170. That is roughly $30 less than the class median, which would run closer to $200 over the same ten years.
How the Samsung WW25FG5B**** compares
The washing machine class we track runs from $7 to $58 a year. At $17/yr, it runs about $3 a year cheaper than the class median of $20, and it is about $10 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.5 cu ft, the Samsung WW25FG5B**** is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, and smaller washing machine models generally cost less to run for the same job, all else being equal. The IMEF of 2.25 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 Samsung WW25FG5B**** cheap to run?
Yes, relatively. At $17 a year it ranks #66 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Samsung WW25FG5B**** cost per month?
Roughly $1.39/mo, spreading the $17/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 90 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $17 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Samsung WW25FG5B**** for its size?
29th 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.
