Model
Samsung WF50BG83**A*
Rank #87 means 86 of the 388 washing machine models we track cost less to run each year; the 88th efficiency percentile means it uses less energy for its size than 88% of those models.
What does the Samsung WF50BG83**A* cost to run per year?
The Samsung WF50BG83**A* costs about $18 a year to run, which beats most of the 388 washing machine models we track; it ranks #87. Few washing machine models we track beat it on size-adjusted efficiency; it edges out 88% of the class once capacity is normalized. The IMEF figure of 3.1 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 WF50A86**A* at $18/yr runs a little cheaper and the Aviva ALWF190WH 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 Samsung WF50BG83**A*'s $18/yr adds up to roughly $180 in electricity alone, before purchase price or repairs.
Also sold as: Lg SWWE50*3.
By the numbers
The Samsung WF50BG83**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 WF50BG83**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 WF50BG83**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 WF50BG83**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 5 cu ft, the Samsung WF50BG83**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, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. Its IMEF of 3.1, above the class median of 2.76, reflects integrated modified energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 WF50BG83**A* cheap to run?
Yes. Its $18/yr running cost puts it at rank #87 of 388, below what most washing machine models we track cost to run.
How much does the Samsung WF50BG83**A* cost per month?
About $1.53 a month, which is the $18 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: 99 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $18 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Samsung WF50BG83**A* for its size?
88th percentile once size is factored in, a fairly typical result for the class.
