Model
Samsung WW25FG6B****
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 WW25FG6B**** cost to run per year?
The Samsung WW25FG6B**** runs for about $17 a year, landing it near the bottom of the cost table at rank #66 of 388 washing machine models we track. Efficiency-wise, once size is accounted for, it trails most of the class, ahead of only 29% of the models we track. Its IMEF of 2.25 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Samsung WW25FG5B**** at $17/yr runs a little cheaper and the Samsung WF45A64**A* 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 WW25FG6B****'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 WW25FG6B**** 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 WW25FG6B**** 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 WW25FG6B**** 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 WW25FG6B**** 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 WW25FG6B**** 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 2.25 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). 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 Samsung WW25FG6B**** cheap to run?
Yes. Its $17/yr running cost puts it at rank #66 of 388, below what most washing machine models we track cost to run.
How much does the Samsung WW25FG6B**** cost per month?
About $1.39 a month, which is the $17 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: 90 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $17 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Samsung WW25FG6B**** 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.
