Model
Samsung WA55CG71**A*
Rank #228 means 227 of the 388 washing machine models we track cost less to run each year; the 77th efficiency percentile means it uses less energy for its size than 77% of those models.
What does the Samsung WA55CG71**A* cost to run per year?
At about $22 a year, the Samsung WA55CG71**A* lands in the middle third of washing machine models we track on running cost, rank #228 of 388. Size-adjusted, this model beats 77% of washing machine models we track on efficiency, better than most of its class. At a IMEF of 2.3, 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 WA55A77**A* at $22/yr runs a little cheaper and the Samsung WA55CG75**A* at $22/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 WA55CG71**A*'s $22/yr adds up to roughly $220 in electricity alone, before purchase price or repairs.
Also sold as: Lg WT8400C*.
By the numbers
The Samsung WA55CG71**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 $22/yr, here is what the Samsung WA55CG71**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 WA55CG71**A* costs about $220. That is roughly $20 more than the class median, which would run closer to $200 over the same ten years.
How the Samsung WA55CG71**A* compares
The washing machine class we track runs from $7 to $58 a year. At $22/yr, it runs about $2 a year above the class median of $20, and it is about $15 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5.5 cu ft, the Samsung WA55CG71**A* is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, among washing machine models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. The IMEF of 2.3 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 WA55CG71**A* cheap to run?
Roughly, yes. Its $22/yr figure is close to the class median, ranking #228 of 388, neither a bargain nor a splurge on running cost.
How much does the Samsung WA55CG71**A* cost per month?
About $1.86 a month, which is the $22 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: 120 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $22 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Samsung WA55CG71**A* for its size?
77th percentile once size is factored in, a fairly typical result for the class.
