Model
Samsung WF50A85**A*
Rank #190 means 189 of the 388 washing machine models we track cost less to run each year; the 75th efficiency percentile means it uses less energy for its size than 75% of those models.
What does the Samsung WF50A85**A* cost to run per year?
Among the 388 washing machine models we track, the Samsung WF50A85**A*'s $20/yr running cost ranks it #190, close to dead center. Its size-adjusted efficiency percentile of 75 is comfortably above the class median. At a IMEF of 2.92, 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 Midea MLH52S7AWW at $20/yr runs a little cheaper and the Samsung WF50T85**A* at $20/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 WF50A85**A*'s $20/yr adds up to roughly $200 in electricity alone, before purchase price or repairs.
Also sold as: Lg WT7250C*.
By the numbers
The Samsung WF50A85**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 $20/yr, here is what the Samsung WF50A85**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 WF50A85**A* costs about $200. That is roughly $0 less than the class median, which would run closer to $200 over the same ten years.
How the Samsung WF50A85**A* compares
The washing machine class we track runs from $7 to $58 a year. At $20/yr, it sits right on the class median of $20, and it is about $13 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5 cu ft, the Samsung WF50A85**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 2.92, 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). 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 WF50A85**A* cheap to run?
Roughly, yes. Its $20/yr figure is close to the class median, ranking #190 of 388, neither a bargain nor a splurge on running cost.
How much does the Samsung WF50A85**A* cost per month?
About $1.7 a month, which is the $20 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: 110 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $20 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Samsung WF50A85**A* for its size?
75th percentile once size is factored in, a fairly typical result for the class.
