Model
Samsung WA50M74**A*
Rank #254 means 253 of the 388 washing machine models we track cost less to run each year; the 56th efficiency percentile means it uses less energy for its size than 56% of those models.
What does the Samsung WA50M74**A* cost to run per year?
The Samsung WA50M74**A* is a relatively costly runner for its class: about $23 a year, rank #254 of 388. Once capacity is factored in, its efficiency percentile of 56 is fairly typical for the class, neither a standout nor a laggard. Its IMEF of 2.06 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Whirlpool WFW560CH** at $23/yr runs a little cheaper and the Samsung WA50T74**A* at $23/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 WA50M74**A*'s $23/yr adds up to roughly $230 in electricity alone, before purchase price or repairs.

By the numbers
The Samsung WA50M74**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 $23/yr, here is what the Samsung WA50M74**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 WA50M74**A* costs about $230. That is roughly $30 more than the class median, which would run closer to $200 over the same ten years.
How the Samsung WA50M74**A* compares
The washing machine class we track runs from $7 to $58 a year. At $23/yr, it runs about $3 a year above the class median of $20, and it is about $16 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5 cu ft, the Samsung WA50M74**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, putting it squarely in the middle of the class on the size lever that drives most of the cost. Beyond size, its IMEF of 2.06, below 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 WA50M74**A* cheap to run?
Not especially. At $23 a year it ranks #254 of 388 washing machine models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Samsung WA50M74**A* cost per month?
Roughly $1.93/mo, spreading the $23/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 125 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $23 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Samsung WA50M74**A* for its size?
56th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
