Model
Samsung WF46BG65**A*
Rank #82 means 81 of the 388 washing machine models we track cost less to run each year; the 82nd efficiency percentile means it uses less energy for its size than 82% of those models.
What does the Samsung WF46BG65**A* cost to run per year?
Do the math and the Samsung WF46BG65**A*'s $18/yr puts it at rank #82 of 388, on the cheaper side of the class. Normalized for capacity, it ranks ahead of 82% of washing machine models we track on efficiency, a genuinely strong showing. 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 Samsung WF45T62**A* at $18/yr runs a little cheaper and the Samsung WH46DBH50*E* at $18/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 WF46BG65**A*'s $18/yr adds up to roughly $180 in electricity alone, before purchase price or repairs.
Also sold as: Samsung WH46DBH5**G*, Samsung WH46DBH50*E*, Samsung WH46DBH55*E*.
By the numbers
The Samsung WF46BG65**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 $18/yr, here is what the Samsung WF46BG65**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 Samsung WF46BG65**A* costs about $180. That is roughly $20 less than the class median, which would run closer to $200 over the same ten years.
How the Samsung WF46BG65**A* compares
The washing machine class we track runs from $7 to $58 a year. At $18/yr, it runs about $2 a year cheaper than the class median of $20, and it is about $11 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.6 cu ft, the Samsung WF46BG65**A* is a mid-size washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. Beyond size, its IMEF of 3.1, above the class median of 2.76, is the class's own efficiency yardstick, integrated modified energy factor, and it is what separates two similarly sized models with different running costs.
- 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 WF46BG65**A* cheap to run?
Yes, relatively. At $18 a year it ranks #82 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Samsung WF46BG65**A* cost per month?
Roughly $1.47/mo, spreading the $18/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 95 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $18 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Samsung WF46BG65**A* for its size?
82nd percentile once size is factored in, a fairly typical result for the class.
